I have had this board (Asus P5b-Deluxe Rev 1.03G) for about 2 years. the problem i am going to describe has been there for about 8 months.
At times the system would just stop responding at all. that means that nothing short of turning the psu switch to off works. pressing the 'reset' button does nothing, neither does the 'power' button. no blue screen of death, nothing. the machine just stops responding to everything.
turning off the power, turning it on usually gets the system up and running and the chances of the samething happening are extremely varied. at times it boots up okay and the problem doesnt come back for what seems like an age, other times it would do the same thing again immediately.
The event viewer shows up nothing (no errors what so ever).
Things that i've noticed:
1. There is no guaranteed way to reproduce the error, however one way that occasionally does this is to change any bit of hardware in my system (be it a HDD, a DVD drive etc). specifically any hardware that need a wire to connect to the mobo. most commonly happens when using a Sata cable.
2. Everytime this happens, the system clock sorta goes to sleep. when the computer starts to run normally, the clock picks up EXACTLY where it left off when the problem began
Things that i've done:
0. Bios updates. no difference
1. Checked Power supply: using a volt meter. all voltages are pretty okay. checked psu in another rig (p5k-vm + 8800gtx) works great
2. Checked Processor in another board (again a p5k-vm) no problems
3. Chekced RAM (memcheck) no errors. checked ram in another system, no problems
4. Undo my oc settings. the problem still strikes if i run my system at default
5. checked gfx cards (4870, 8800gtx). get similar issues with both cards.
6. checked multiple hdds in the system (greatest stability with IDE HDD)
The problem is that if i am to RMA this board i have to write in exactly what goes wrong and how to reproduce it (that is the way things go here :( ) . as this error seems to just come on its own, i have no sure way of reproducing it.
I checked asus's forums and came up with this:
http://vip.asus.com/forum/view.aspx?...Language=en-us
this describes the problem EXACTLY. but the solution doesnt work for me atleast. i've tried 4 different sets and i get problems with all of em. the last set i tried i pulled out from another system where they were working fine.
I really am running out of ideas as what to do. the simplest to me is to get another board and try my luck with an RMA (takes upto 3 months to process one).
I really dont want to go the new board way as i am tempted by the core i7.
Please if anyone has any ideas please lemme know!
sys specs:
1. Asus p5b-d rev 1.03G (bios 1236) + Intel Q6600 @3.0Ghz + Tuniq Tower 120
2. Corsair 2x1Gig DHX XMS2 RAM

I would first think Power Supply, but you have a good one. And, you said you checked it. Do you ever run a program like Everest that post the core volts and rails. There is a good Vdroop with this board. I run the CPU at the high end of the specs.
What about the sound card? Did you ever test it without it?
I will go i7 eventually also. Just want the prices and the tech to mature a little.
Any good for my settings? I need to look to see if there is a 64-bit. This is a 1 time run with some system load.
Not that long ago, I reduced my setting to 3.28 GHz/ FSB 1640 MHz Mem 820 MHz, 5-6-6-18, Also I have C1E enabled.
I was at 3.36 GHz/ FSB 1680 MHz Mem 840 MHz, 5-5-5-15

alitayyab: I was using a Q6600 - G0 for a while on my P5B Deluxe and it was far harder getting it to run fast and stable compared to any Dual Core I've tried.
I've found that even with the Dual Core, when you have random instability issues you can improve things with more chipset voltage. I definitely wouldn't set anything in the bios to AUTO for voltage or anything else for that matter on this board.
What are your settings on the voltage tab in the bios? When I first started overclocking the P5B I could run for hours, Prime stable and then a day or two later at the same settings I would have weird problems, usually at 0% load, surfing the net or something and my computer would lock up or reboot. It made no sense but extra voltage fixed pretty much everything.
The only issue I have now is that sometimes when I reboot, my wireless keyboard isn't recognized in the bios. I can hammer away on the Delete key when it is booting up in the bios but nothing happens. After it gets to Windows the keyboard works fine. I think it is designed like this by Asus so if you are using Hibernate mode it won't let you make any bios changes but sometimes it gets confused and even if you use ShutDown it still locks you out of the bios and you can't push F8 either to bring up the boot menu.
I thought this was just a wireless keyboard issue but I plugged in a PS2 keyboard and same thing. I've read in forums that I'm not the only one with this issue so I've learned to live with it. It doesn't happen very often and if I wasn't trying to overclock the chipset 100% it probably wouldn't happen at all. :D
Turning off the power supply switch for 30 seconds usually fixes this.
My E8400 C0 has no issues with voltages and overclock settings being saved or lost with bios version 1237. Hopefully they fix this issue with the next bios release for your E0 Quad.
all voltages are set to their lowest value except for Vcore which is 1.3125.Quote:

Asus in the US has a very small office for customer service. They can ship you an advanced replacement if you have a credit card.
I don't know if you are in the US.
Up them volts. I run my CPU 24/7 for a long time now at 1.39v at idle. I test it by looping prime95 and 3DMARK06 simultaneously. The 3Dmark really brings out the Vdroop.
The bios setting CPU volt is much greater. But, it gives me 1.39V. I think I have the bios at 1.45+ as a setting.
I would up some other volts as well
I use bios 1219 for the Q

Why? Some of these boards are very sensitive to chipset voltage settings and I can almost guarantee you that if you start bumping those up, your problems will go away. Here's a good place to start:Quote:

I've been using the voltage settings in the screen shot above for the last year and a half if not longer and I haven't hurt anything yet. Stability is excellent.
okay i'll try higher nb volts.
but shouldnt the board atleast respond to a hard reset EVEN if this is a chipset issue???
in my 20 years i've never encountered a problem like this.
unfortunately i am not in the US, thus my slightly off RMA process where i have to show the distributor what is wrong with the board.!

c. 8 multi has a FSB wall @ 400 (you need a very insane and high Vcore for a 45 nm CPU)
d. CPU runs quite stable for 6 h with Prime 95 in all instances with only 1, 1 V @ 3 GHz (8x 374) with 2 x 2 GB Apogee 1150 RAM (1.45 V NB )
but fails immediately with IBT and OCCT (CPU /RAM) in seconds

mine: What speed and voltage were you running your Apogee memory at? The P5B has a strap change at 400 MHz so it is a lot easier to run stable at a FSB of 401 MHz than it is to run at 400 MHz, especially with a Quad. I assumed you tried using lots of voltage for the northbridge, etc. to try to get your computer stable. What sort of temps do you get up to with Prime small FFTs?
The P5B isn't exactly top priority for the bios writers at Asus these days but they seem to keep making some slow progress with each release. My E8400 - C0 is pretty happy on the P5B Deluxe now. It needs more chipset voltage than my original E6400 ever did but whatever makes it happy, I give it.
With lots of FSB MHz for my E8400 - C0 I was having trouble in the bios with it locking up while I was making adjustments but 1.65 volts for the northbridge sure cured that! :D If you plan to replace your board then don't be afraid to give it some juice. Slower, more conservative, memory speeds with CL4 timings works more reliably for me than DDR2-1100+ speeds and CL5 timings. With the tighter CL4 timings, the performance loss is minimal.
I also pulled off my northbridge heatsink a long time ago. It wasn't sitting squarely so I bent the heatpipe a little and used some AS5. If a person was serious and didn't mind some extra noise then bolting a small fan to it would probably be a good idea too.

Right now NB is @ 1,45 V . i got some kind of lockups in bios just as you reported and weird "no boots" even with bios @ default.
(1,65 V mmmhhhh .. should I ?????)
Biggest shock are the stability tests in IBT and OCCT :
Failure in seconds even @default 333 FSB @2,83 Ghz
Even with Vcore 1.3V (from 1,12)
I like the way Asus is supporting a 2 year old board but please not in that way .. This is just frustrating ...

EDIT : So I followed Uncles advice and upped the voltage on the NB to an insane 1,65 V ! Temps were incredibly high ..I measured 84 C .. . So i installed a 80mm Yateloon silent fan @7v , pointing in the NB direction. And guess what ? Cured a lot of problems . Not all . ..but got my first clean IBT run (256 MB RAM)
Prime 95 custom runs for 6 hours without any problems with a mere 1,09 V (CPUZ) 1,12 in bios. Amazing.
Thanx

mine: I have no idea why the northbridge requires so much voltage with 45nm but it does seem to help overall stability. I found 65nm Quads were similar needing more chipset voltage than 65nm Dual Cores. Maybe with the next bios release they will have figured something out and I'll be able to drop it from 1.65 volts but until then, I'm leaving it.
As you said, it cures a lot of problems but it doesn't fix everything. I still have a resume from Stand By issue when the FSB is at 500+ MHz but with the 9.0 multi on my E8400, I can survive with 450 x 9.0
Most people are running their new ATI 4850 cards at 80C so I don't get too worried about temp numbers as long as things are stable. The shutdown temperature for Intel Core CPUs is approximately 125C so even though 80C or 85C sounds like a big number, it probably won't hurt anything. What did you use to measure the temperature? I just checked the heatsink on the NB with an IR thermometer and it's presently showing only 48C. I know it can get a lot hotter than that. Next time I feel the heatsink with my magic finger and some skin comes off I'll try another IR measurement. Do you have any software that reports NB temps? I didn't think Asus Probe reported that last time I checked.
Using a program like SPDTool might help give you some control over your SPD memory timings. It's pretty easy to use. Minimum Refresh to Active/Refresh Command Period... is where you can make adjustments to tRFC in the SPD table. I'm not sure if the Asus bios will respect your request or if it will be ignored if it is out of the range that it can handle.
Edit: I just ran Prime Blend for about half an hour. The NB voltage was at 1.65 volts and the IR measured temp of the heatsink was about 55C. I was really surprised when I pulled my heatsink off and noticed what poor contact it was making. Pull it off, put it on a flat surface and bend the heat pipe a little until it allows both ends of it to sit square. I don't have any before and after numbers but a heatsink that is making full contact with a chip has to be better than one only making contact on the corner of a chip. I'm usually not the type of person to check stuff like that out but I'm glad I did.
Now that I stopped Prime, the NB measured temp is about 49C to 50C and the southbridge heatsink is measuring 58C to 59C. No worries.
Edit#2: 57C measured on the NB heatsink is equivalent to being able to hold two fingers on the flat side of the heatsink closest to the graphics card for about 10 seconds. Your mileage or fingers may vary. Try holding your fingers on a Gigabyte DS3 NB heatsink and you'll find out what hot is all about! :D
Thanks a lot UnclewebbQuote:

Now after getting all primestable for 8 hours
only my IBT failures @ mild overclocking (FSB 375-8x) give me a lot of headaches
I got 50 runs with 512 MB flawlessly
and 5 failures with 1024 MB RAM chosen.. (NB from 1.45-1.65 V)
EDIT: not even IBT stability @ default FSB/VCore and setup default in Bios
How are you measuring the temp of your northbridge at 84C? If you are using software then I'd like to try running the same program just to compare. If you're using an IR thermometer like I have then I'd suggest pulling your heatsink off and having a look at the contact it's making.
If you're stable when using 512 MB but not stable with 1024 MB then I'd try adding a little more memory voltage. I've found that a bios setting of 2.10 to 2.15 volts works great for many different types of DDR2 ram. Even modules that are only rated at 1.8 volts will run stable at a faster speed with some extra voltage. That seems to be a common theme for me. :)
You might burn your ram out at 2.5 volts but 2.15 volts long term won't hurt anything. There usually isn't much to be gained going beyond 2.15 volts in the P5B Dlx bios for 24/7 type use.
Does the 1024 MB test run longer and create a higher CPU core temperature? When well overclocked, most CPUs will lose long term reliability when the core temperature hits 65C to 70C. Every CPU is different and the amount of temperature head room you have varies depending on how hard you're pushing your CPU. Use a nice program like RealTemp which can keep track of your maximum core temperature and you might see a pattern develop between core temperature and stability.
There are some FSB speeds that are easier to run stable at. You lose performance when the FSB goes over 400 MHz on the P5B due to the strap change but it's easier to run reliably at 410 MHz then it is to run at 390 MHz. I'm not a big fan of the 366 MHz to 400 MHz range. Try running with a FSB just over 400 MHz and then use a smaller CPU multiplier so your overall MHz are about the same. This might help isolate your problem.
Personally, I find IBT to be a little bit overkill. It's great to be IBT stable but do you ever use any real world software that heats your CPU up to within 10C of what IBT heats your CPU up to?
IBT is sort of like putting a brick on the gas pedal of your car and then going to sleep for the night. If your engine blows half way through the night then I guess it wasn't "brick stable" but since I never drive around with a brick on my gas pedal then not being "brick stable" isn't really a problem for me or my car. I like being Prime small FFT stable but even that is borderline overkill because I don't use any real software that runs the floating point units of both cores of my CPU at full load for extended periods of time.
Edit: I just tried the LinX front end for linpack and the bigger the test, the more the core temperatures go up so you might be hitting the wall due to excessive CPU heat.
thanx unclewebb , appreciate your efforts
Unfortunately (not for me , but for my computerparts) I use a small Silverstone HTPC case .
Though the 9550 E 0 was incredibly easy to cool. I use the small Noctua (9 vers.) heatsink in a pushpull config. with 2 scythe Kama 92 mm PWM fans.
idle : highest temp.: 36 C (core 1) @ 22 C room temp.
load : highest temp : 58 C (core 1) @ 22 C room Temp (IBT-max memory)
So even with small FFts I never saw temps exceeding 54 degrees.
I measured the NB temps again with an IR Thermo. @ 1,55 V after 30 min. IBT and got 62 degrees.
Will reseaten it and apply new Noctua TP .
I tried adding some more juice to the Apogee RAM before (2,2V) but , sorry to say,that was contraproductive. (no Micronchips inside ) they run best @ 1,9-2,0 V)
very interesting : FSB 400-410 @ 8x multi gave me much more problems
than 380x8,5 , thats quite unusual , isnīt ?
Just for fun I reinstalled my trusty old E 6600 (first gen. ES) ....whow what a stable configuration
Really no problems at all ...rockstable with Prime-and IBT
though interesting ...same problems with FSB 400 +
I remember for sure , there were no such problems at all 2 years ago ... I just look at screens with
Superpi 13,0 sec and FSB 9x 420 and 8x 440.
So I think the board may have some kind of degradation or is getting old , Just doesnīt like young speeedy cpu girls inside the house or 2x2 GB 1150 sportscars
like all of us , very sympathic .. in a way ....
May be my young speedy blond girlfriend should get it as a present , playing solitaire on it.

Hello!
I'm planning to buy 8GB of DDR2@800MHz for my ASUS P5B-Deluxe BIOS v1236.
The RAM in question is this:
G.SKILL F2-6400CL5Q-8GBPQ, DDR2 800 MHz, KIT 4x2 GB
details:
http://newgskill.web-bi.net/bbs/view...d=g_ddr2&no=95
I'm going to run a 64bit OS with memory remap enabled. I'm pretty sure that I'll be able to allocate all 8GB BUT...the question is will I be able to run it @ 800MHz (which is the default max for P5B-Deluxe)?
I'm asking you experts this becaue I stumbled upon this:
http://forums.hexus.net/pc-memory/10...5b-deluxe.html
to be precise, post #13:
so, what say ye?Quote:
You probably found this out by now, like i did just recently when I bought a Asus P5B Deluxe board... but the 8Gb possiblity of the server can only be done on DDR2 PC5400 or DDR PC-5200 RAM (677 or 533 respectively), as the board doesnt support anything more then 4Gb total in PC-6400 RAM.
Also the above configurations will only work with specific manufacturer chips...I put 4 x 1Gb PC-6400 Rambo ram on my board, and it only detects 3Gb.... which sucks big time..... seems the board manufacturer had a marketing agreement with specific ram manufactuers.... no offense to Corsair, as I'm now looking for the required 4 x 2Gb Corsair RAM for the board to get it to 8Gb but my current problem is that ASUS dont provide the details of the supported RAM modules for 8GB.
If you have done this already Agrippa, any advice would be appreciated!
P.S. please no "why do you need 8GB of RAM?" :eek:
Hi
I think my MarvelYukon died . one RJ45 blank the other orange . using PCI NIC .
Does anyone know where the chip is located ? and what voltage can be changed in BIOS to add juice to it ?
mine: Your CPU temps look good and shouldn't be causing a problem. Most memory scales upward with more voltage but from what I've read about the Apogee, it doesn't need extra voltage like the Micron D9 chips do. TweakTown didn't really gain anything by going beyond the rated 2.1 volts when they tested some DDR2-1150 Apogee GT 2x2GB modules last month. Have you ever tried slowing your memory down and running it 1:1 with CL4 or CL5 timings when checking stability? I've always preferred that to big memory MHz numbers on this board.
Maybe the next bios release will help with E0 compatibility. I'm pretty happy with how my E8400 - C0 runs now on the P5B Deluxe but I haven't tried using a 45nm E0, Dual or Quad on the P5B so I guess I can't help you. One board has lasted me for the entire Core CPU generation so I can survive now until Core i7 comes out.

Hi Guys!
I'm having a problem with my P5B dlx, I hope you guys can help me.
I apologize for the long post, but please bear with me:
I had a pair of Crucial ballistix (2x1gb, 800mhz) which I had running at 1200mhz, 5,5,5,12 @ 2.15v- they ran perfectly at those speeds for a couple of months - then after a overclocking session, I pushed them even higher and increased the volts to 2.4 (If I remember correctly), anyway, this fried the ram.
So I got another set of ballistix - (unfortunately the single sided ones) and now I cant get them to run at the rated speeds (They are supposed to be able to run at either 800 @ 4,4,4,12 or 1000 @ 5,5,5,15 - STOCK) I've tried different voltages ect, but it doesn't seem to help.
Now I originally thought that there is something wrong with the ram, so I tested them in a friends pc and the work perfectly at 1000mhz without having to change anything?
At the moment I've got a E0 e8400 445 x 9 @ 1.25 and the Ram at 890 @ 5,5,5,15 - this is highest they will go.
I'm running the latest bios 1237 - I've also tried 1236, still no luck.
My NB Vcore Voltage to 1.45V.
Both my NB and my CPU are watercooled - and the only mod I've done is a Vdroop pencil mod
Now I've gone over my bios settings again and again, tried different timings, volts, sub timings, sub voltages still no luck.
I've tried resetting the bios to stock and only changing the ram speeds - it still wont boot.
Is it possible that I've damaged something on the board?
Any ideas - this is driving me crazy!
Agail: As I mentioned above, I think this board appreciates more NB voltage when using the newer 45nm CPUs. My NB is only air cooled but it seems to like having the NB set to 1.65 volts in the bios. On the previous page I posted some bios voltage settings that are working good for my E8400 - C0.
http://www.xtremesystems.org/forums/...postcount=4925
I think the facts of life are that this board is a couple of years old now and it is not really optimized for some of the newer memory. Some new sticks that can run DDR2-1200 speeds on a newer board with a newer chipset probably won't be able to run that same speed on a P5B Deluxe. Asus makes a little bit of progress with each bios release but it just isn't that high a priority for them.
When you say that you can't get them to run at the rated speed does that mean they aren't Prime stable or you can't even boot up?
I was having some boot up issues before (it would hang) but I was running some mismatched sticks. One was a Ballistix 1GB and the other was a Team. With the extra voltage and some new OCZ DDR2-9200 Reapers it's been trouble free lately.
It's also possible that your CPU might need a little more voltage now. After the initial burn in some 45nm CPUs need a little more voltage to run the same overclock.
just to add
you may try memset
sometimes a problem of high performance DDR 2 RAM and the P5 B bios
are the tRFC settings : 42 (default)
for high-speed RAM 1100 Mhz +... thats way too low ..try > 60
there is and sorry to say never existed an Asus bios that changed these way too low timings .
I was able to squeeze 1120 stable out of the 4096 Apogee 1066 set (not so easy with 2x 2GB RAM sticks)
with > 9100 read speed in Everest @ only 3 GHz

um...anyone care to answer my question? :)
snnoopypw: Sorry, I haven't tried running 8GB on a P5B at DDR2-800. You might have to be the guinea pig and give it a try. Even if some user posts that he did it, you might try it and it might not work with your ram.
I do know that the guy that said this:
was probably just running into the limitations of a 32bit OS.Quote:

I tried raising the NB to 1.65v, but it didn't seem to make a difference.
I've tried this ram with my e0 e8400 as well as a c0 e8400, no difference.
I've also tried increasing Vcore, but that doesn't seem to be my limiting factor.
I think your theory on the bios not being optimized for newer memory, seems to be the most plausible explanation - unfortunately, I don't have any other high performance ram handy to test it with.

It's almost as if one of the recent bios updates has negatively effected ram compatibility. When I first got my 2x1GB Team memory it worked great but then it developed the problem where it would fail to boot sometimes. I thought one stick was bad so I swapped in a similar Crucial 1GB stick and it worked for a while but then it also developed the fail to boot issues. It got so bad at times that I'd have to swap in my 512MB Micron DDR2-667 to get it to boot up again so I could get in the bios. This was never a problem with my original E6400 but the 45nm E8400 - C0 seems a lot pickier when it comes to memory.
Since swapping in the OCZ Reapers, I haven't had this problem once. When I get the chance I'll try taking the SPD data from the Reapers and burn it to my Team memory to see if I can create some Frankenstein modules that don't have this boot issue with the P5B.
It should be here next week, thanks for the heads up. Ill post up what happens after its in.Quote:

So far so good with 1.65 volts to the northbridge. If there was a bios setting for 1.75 volts I think I'd try that. My room temp is only about 20C so the NB temp isn't too bad.Quote:

I figure if I fry this board then I'll have a reason to get a P5Q Deluxe or similar. This P5B has had some quirks during its lifetime but at the moment it's running pretty good.
I was running perfectly stable(12+hrs) Orthos at 9*355 and I decided to try and
run 8*400 so I could run 1:1 RAM. When I applied the settings everything booted fine and loaded windows properly. Once I was in windows I started Orthos to test it at the new settings and it froze after ~20sec. Ever since it froze I have not been able to get it to boot again. I've searched a lot and tried numerous fixes posted by people with no results. I'll list what I've tried.
1. Initially just jumpered the reset CMOS for ~10sec, nothing
2. Removed battery and jumpered CMOS, nothing
3. Disconnected all CDROMS and hard disks, nothing
4. Removed all RAM and booted it with none, then rebooted with one stick, nothing
5. Left the power off and unplugged all night, nothing
6. The one last thing I'm trying is leaving the CMOS battery out and the jumper set all day while I'm at work.
Also, ever since it froze when it boots new it will boot the turn off for a bit then reboot. Almost like it does when you apply new clock settings. I'm really at a loss for what to do and would appreciate any help/advice. Do you think the board is dead and if so what new board should I consider without dropping $300. Thanks!!
WHat ram you running? Got a different stick you can try? One of mine last night, I came home to a frozen rig, rebooted, & was doing what your describing. Did the cmos & still had the prob, swapped out the ram & bam! it booted. Hope this helps.Quote:

I had 2x1GB Corsair XMS2 DDR2800 installed and had just bought 2x2GB corsair xms2 DDR2 800 and was running with all 6GB installed. Bios and windows had recognized ram properly. When I started having problems I went to using just one stick of the 1GB in Channel A.
Try a different stick of ram then. What NB voltage you running, im not too sure on that amount of ram & this mobo, most I ever run is 2 gigs. It will end up booting for you, these boards are just plain buggy at times. I had to let one of mine sit for 2 days before i applied power to it & it finally booted.

Well, before it began locking up I was running Auto NB Voltage. I'm not sure
what Auto sets it to or I would have bumped it one notch maybe. Now that It won't boot obviously I can't change anything. Is a NB voltage increase typically required for 4 sticks? I agree, this board is very buggy at times. I've had problems where when upgrading the bios I could never get the BIOS to detect all my SATA drives. I had to downgrade to 1223 since that's the only bios that would work right. I haven't tried any of the new beta ones. What is the typical bios most people overclocking run on this board? I'm not truly convinced it's bad I'm just running out of options. Really appreciate you trying to help me out.
jgree32: My P5B also has a history of being buggy when pushing it hard and trying settings that it doesn't like. It gets into a mode where no matter what you do, it won't boot up. I'm using the most recent 12.37 bios and same thing.
The easiest thing that works for me is I have some Micron DDR2-667 2 x 512MB sticks of ram. They actually have D9GMH chips on them but only single sided. As soon as I stick in one of these sticks, it will immediately boot up so I can get back into the bios and go from there.
When trying to get it going again, use only a single stick of memory. Another thing that has worked for me in the past is briefly removing the graphics card. Power it on and then turn it off and replace the card again. You need to trick the board into thinking that something has changed so it dumps the bios settings that aren't working. I've found that 65nm Dual Core CPUs get into this "won't boot" mode less often than my 45nm E8400. I also have a cheap E2160 65nm Pentium CPU available to swap in to shock this board into booting up but I've never had to go that far.
I actually spent all day yesterday deliberately trying to force my board into this "won't boot" mode so I could try and understand it more and come up with some ways to fix this issue. I succeeded several times! :D
I found that having inadequate memory voltage when going for big DDR2 MHz numbers or tight timings was a good way to cause this problem.
I think having the northbridge locked at a minimum of 1.55 volts is a good idea. I wouldn't use any AUTO settings on this board because you'll never know how much voltage anything is getting. It gets pretty stupid when set to AUTO for CPU voltage so I don't trust it for anything else.
I've been using 1.65 volts for the northbridge lately. The advantage I've found with this is that when using SetFSB, I can jack the MHz up or down in one step by a huge amount without it locking up. With inadequate northbridge voltage, I have to move the MHz slider in baby steps. I also tend to get more lock ups when making adjustments in the bios when at a high FSB if the northbridge voltage isn't high enough.
Anyway, I decided to create a generic SPD setting for my old 1MB sticks that used to be kind of cranky. They are both double sided and rated DDR2-800 at CL4, one Ballistix and one Team, so I wanted to come up with a common SPD setting to use for both of them to try and cure some of the boot issues.

More details in a minute or two about how that went.............
I should have posted more info about my system specs, I apologize for that. Just really irritated with this board right now. My specs are as followsQuote:

6GB Corsair XMS2 DDR2 800
I've had problems getting boards to boot before but this has proved to be the worst yet. I really don't believe it's dead but with all the things I tried I began to get a little worried. I don't have any old DDR2 lieing around. All I have is 2 2GB sticks and 2 1GB sticks so I guess I could try those one at a time to see if it helps. I haven't tried the video card thing you mentioned so I'll give that a shot. I do have a 7800 gt I could borrow out of my other Pc, do you think swapping that in would help anything? The other PC has DDR 1 otherwise I could try it's RAM and it's an AMD machine so no swapping CPU. Also is there a list available somewhere that shows what the AUTO voltage settings set to. I'm currently using vcore set to 1.35, Memory set to 2.1 and all else on auto. I didn't really know what to set the NB or FSB or any of those voltage to.
Set the NB to 1.45-1.55, unless your going crazy on the OC. Im good with 1.55 for 550fsb. You can run the vfsb all the way up & it will be fine. I run my e6600 @ 3.8 24/7/365. The memory is where you are having the issues. Got a local store where you can pick up a 512 stick to get it back up & running? Another option is to pop out the cpu & put it back in. Like unclewbb said, you need to trick the mobo, sometimes there is no method to this madness, sometimes some things work to bring it back, while sometimes what you did the last time wont work this time.Quote:

Did you try removing your graphics card or moving it into the other PCI-E slot?
I had a nice Prime run today with my E8400 at 7.5 x 533 ~ 4000 MHz. I'll post some bios screen shots so if you ever shock your board back to life at least you'll have some good baseline voltages and memory timings that you can try.
I did try removing the graphics card and booting without it. I also tried removing the CPU and booting without it. I've also tried a different video card from another PC. I just can't believe that none of the things I tried worked. I guess maybe something was going wrong with the board or something for this to happen at settings which it booted at fine. I really have no idea at this point but I will try the other PCIE slot. Any suggetions on motherboards if I have to buy another without dropping $300. Thanks again! Oh, also forgot I tried another PSU.Quote:

It sounds like you've tried pretty much all of the normal tricks that usually work. I recently helped a friend with his new Asus P5Q Pro. It was inexpensive but overclocked well and had a decent cooler on the northbridge similar to the P5B. I also like Gigabyte boards but haven't used one with the newer Intel chipsets so I can't help you too much.
My P5B was rock solid today with some new settings. Here's how it did running Prime small FFTs for the day:
http://img396.imageshack.us/img396/5...3mhzig9.th.pnghttp://img396.imageshack.us/images/thpix.gif
This was with a bios setting of 1.55 volts for the northbridge. Here are the voltages and memory timings I used:
http://img378.imageshack.us/img378/8...voltagenn3.jpg
My E8400 (C0) runs OK but has always needed more voltage than most. The trips to 100C and beyond might have something to do with that! I think a fresh E0 stepping should run 4 GHz, Prime stable, with 1.30 volts or less.
http://img515.imageshack.us/img515/7...smemorysf3.jpg
Edit: I originally had the Static Read Control set to Faster but later learned that this can cause "unable to boot" issues when the FSB is at 333 MHz which is the default for an E8400. This changes the Performance Level as reported by MemSet. Not by much but enough to cause boot troubles with some combinations. At 533x7.5 on the Faster setting everything was fine but at lower FSB MHz it was problematic.
Nothing too complicated but check out the memory write bandwidth.
Newer DDR3 chipsets with aggressively overclocked CPUs would be envious of a number like that:
http://img407.imageshack.us/img407/2245/everestxh5.jpg
I was using my mismatched DDR2-800 ram but both sticks have D9GMH chips on them. I designed a new SPD table that I used so they would match up better and hopefully cause fewer problems at boot up. My Reapers have been pretty decent so far at booting up so I borrowed some of the settings from them and from the net and did lots of testing yesterday. The 965 chipset doesn't use the EPP settings so I got rid of all of them and I turned off the CL3 and CL4 SPD settings since I want this board always using CL5. Unfortunately, after a bunch of hard work, I learned that the P5B ignores most of the information in the SPD tables within the memory modules.
I thought boosting tRFC up to 56 and tRC up to 32 might help at higher frequencies. I created a SPD table with those settings as shown in my earlier post above but when I booted up, the P5B sets that to 42 so there is no advantage. You can adjust that with MemSet once you're in Windows but that isn't going to help any if you can't even boot up. My run above was with tRFC = 42.
I tried SPD timings of CL5-5-5-15 or -18. The P5B only sets CL5 and ignores the rest. Those two settings both end up as CL5-6-6-15 when running MemTest86+ or booting up into Windows. This might help explain why this board sometimes has problems booting up. It ignores most of the information in the memory SPD tables.
The modified SPD table I created is working OK for me today but with the P5B, tomorrow is another day. No lock ups recently other than ones I've deliberately tried to create. I might play some more tomorrow to see what else I can learn. I'll also post the SPD table I created if anyone wants to have a look at that. I'm not yet sure if it is helping me in any way since I had to use manually set timings when testing and most of the info is ignored by the P5B.
Edit: Resume from stand by is working 100% with these settings.
Nice and interesting and corresponding to my findingsQuote:

Write peformance is clearly lower with the much lower FSB
But what about your latencies ?
Best
m
The L1/L2 cache latencies are different because your screen shot is for a 65nm CPU while my screen shot is for a 45nm. Intel likely changed the latency settings when they introduced the new CPUs for better stability at high MHz.
As for memory latency, usually the less the better. The most important numbers though are always memory bandwidth or how fast a CPU can read and write information to and from your memory. I'm not sure what spec, read, write or copy, is the most important to overall performance.
I tired to run my E8400 at 9.0 x 348 for a better comparison. My CPU is capable of that but my memory choked. I switched to the OCZ DDR2-9200 Reapers but they didn't have the balls to run at DDR2-1160 either. They are officially rated at DDR2-1150 but on this board they struggle and need too much voltage as soon as they go over DDR2-1100 speed. For my combination, I get excellent reliability and decent performance keeping them at DDR2-1066 without needing to go over their rated 2.1 volts.
When overclocking I get my best 24/7 results by finding out what my CPU can do and then adjusting multipliers and memory speed so that the memory is optimized. In real world use, there's not much difference between DDR2-1000 CL4 or DDR2-1100 or 1200 with CL5 timings. Most benchmarks that show a large difference that I've seen are usually when they are making a comparison with two totally different CPU speeds.
I'll have to go try some benches. Setting my CPU to 8x500 and using DDR2-1000 CL4 timings might be best for my combination. This CPU has seen 4500 or so MHz but it needs too much voltage to run reliably at much over 4 GHz for 24/7 use.
One thing I learned during today's testing was that the memory bios setting, Static Read Control can cause some boot problems.
I returned my CPU to default (9.0 x 333) and with the memory set in the bios to DDR2-667, it booted up fine. I rebooted and tried the next setting, DDR2-833 but it would not boot up. Static Read Control was set to Faster at the time. I tried using Fast but the same thing. It would boot up fine when this was set to AUTO or set to Disable but it didn't like Fast or Faster even though my memory was only trying to run at DDR2-833 CL5.
Just another P5B bug. I re-did my memory bios timings page in the above screen shot. If this item causes problems then I think it's best to leave it disabled.
Just for comparison, I ran Everest at DDR2-1000 CL4.
http://img529.imageshack.us/img529/5...1000cl4or5.png
DDR2-1066 CL5 is a hair better, not that anyone would ever notice.
CL5 also needs about 0.10 to 0.15 less memory voltage so I'll be sticking with that.
Edit: I also figured out that the Static Read Control setting in the bios changes Performance Level as reported by MemSet. When set it to Disable or AUTO, Performance Level gets set to 13. When set it to Fast, Performance Level changes to 12 and when it is set to Faster, Performance Level changes to 11. You get a couple of extra MB/s of memory bandwidth but that's about it. With the P5B, it's hard to notice a significant difference whether this is set to 1 or 15. If you have any "unable to boot" issues then set it to Disable and if you don't have any problems then I guess set it to Faster.
wow, i really like seeing the old chipset doing so well, have to say that my own p965 does just as good but it struggles with my sticks. so using a 45nm wuad wiht this board is kinda problematic?
I've pretty much hit the wall here. It might be Prime stable too but I haven't run it long enough to prove it.
http://img98.imageshack.us/img98/348...4050mhzyf7.png
I think it's my memory or how I have it set up and not the chipset that's holding me back here. No complaints though! :D
Last time I tried my Q6600 I wasn't very successful but I didn't push it too hard. With this new memory and a few more tricks, maybe I'll put it back in to see what it can do. The P5B works great with Dual Core CPUs. With this board I'd rather have an E8500 or E8600 (E0) than a Quad and I'd be trying for 535x8.0 for 24/7 use to get some good numbers out of the chipset and memory.
Edit: There was a little bit of extra performance still hiding in that chipset that I didn't know about, until today that is. ;)

:confused: im thinking of getting a E8500 should I ? looking to get 4.5GHz + with this mobo cuz the E8400 is like only $25 less and the E8500 and the E8600 is $80 over the E8500 and $105 on the E8400
Dom7184: The E8500 E0 seems to be the sweet spot at the moment.
After what I learned today, I can only think of two words, "Get It!" :up:
yeah now I need to make sure ill get a E0 :p:Quote:

It's end of the line for socket 775. Intel has some new CPUs coming out next month but you will need a new motherboard and some new DDR3 to run them. The way an E8500 can run on this two year old motherboard, there's no reason to even think about upgrading. Maybe Christmas 2009.
When I was playing this week I sometimes had the problem with it freezing up in the bios while making adjustments and I don't think I'm the only one that's had this problem. The bar at the top of the screen will keep going back and forth from left to right but it won't let you make any adjustments.
I'm still testing but I think bumping these two items in the bios up to 12 has got rid of that problem:
Rank Write to Read Delay
Write to Precharge Delay
It seems more compatible when using a high FSB speed. I used to have these set at 10 and 11 but now both are at 12. I'll see if I can isolate this problem further. Right now this board is running incredible for me. Very easy to set up and get decent results from.
Anyone not sure if they should stick with this board with an E8500 needs to read this thread:
http://www.xtremesystems.org/forums/...d.php?t=182051
Setting the NB to 1.65 volts is necessary for me when using P965StrapTweaker to maintain excellent memory bandwidth and stability at a FSB of 533. Highly recommended.
Edit: I thought running on the fast strap when the FSB was over 500 MHz might cause some instability but after a few hours of Prime95 blend, it looks good enough for 24/7 use.

Look for Intel sSpec Number SLB9K on the box or CPU when looking for an E8500 E0.
but there is going to be some more 775 when i7 comes out cant remember where I saw it
also my mobo fully modded just the vdroop is pencil
cuz i was looking at the ASUS P5Q Deluxe, ASUS Maximus II, ASUS P5Q Premium, ASUS RAMPAGE FORMULA, ASUS P5E Deluxe
I think the new 775 CPUs will be budget processors.Quote:

Usually when a new line of processors is introduced, the old line is slowly phased out. There's not much point of them releasing any performance Dual cores beyond the E8600. They'd rather those users switch over to Core i7 that will have higher margins and maybe they'll be able to sell a new board or two while they're at it. I just read today that Intel has released the budget E7300 with plans for an E7400 as well.
which one ?
1. E8500 & Asus P5B Deluxe (Vdroop Pencil Mod) [Vcore, Vmch & Vdimm Hard Mod] Already Own
2. E8500 & ASUS Maximus II Formula

hello folks!
I have a question regarding this combination:
ASUS P5B Deluxe (BIOS v1236) + G.SKILL 8GB (4 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Quad Kit Desktop Memory - Retail + C2D E6600
memory specs are:
so, how should I set CPU and memory timings? I don't plan to overclock.Quote:
Tech Spec
Capacity 8GB (4 x 2GB)
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Timing 5-5-5-15
Voltage 1.8V - 1.9V
Heat Spreader Yes
Will the memory work@800MHz with this CPU? If yes...how? If someone could explain.
snoopypw: Why not get some Reapers like I'm using?
http://www.newegg.com/Product/Produc...82E16820227267
You could buy 2 sets of Reapers and with the $20 rebate you'd save some money compared to the G.Skill you're looking at.
The P5B can overclock much higher when using only 2 sticks of memory but if you don't intend to overclock then you shouldn't have a problem. There is very little difference in performance between DDR2-667 or DDR2-800 so if your memory doesn't run or isn't stable at DDR2-800 then set it to DDR2-667 in the bios.
8GB of memory is dirt cheap these days so buy them and see how it works for you. If you're not happy then dump them on EBay. The Reapers have a good reputation so you won't have a problem selling them. Hell, I'll give you $100 for 8GB of Reapers! :)
You should be able to do that, though you won't be able to OC the RAM much if G.Skill has the SPD foolishly setting tRFC to 43 like on my G.Skill DDR2-800 5-5-5-15 PQ kit.Quote:

I think it's right place to ask this question: Does P5B-dlx have problems with new E0 stepping? I read in few places that is impossible to change Vcore on this MBO when using E0 stepping CPU.
This also relates to P5B vannila, which i own. I'm willing to buy new E0 stepping CPU, but I'm concerned about this problem. I'd like to stay with this board, i don't see reason to upgrade to P35/45.
Thanks in advance!
Yes it does have problems. I was on the latest bios & trying out my buds es e8400 & the bios was all wacky. Vcore wasnt there was one of the issues. But this was on a ES cpu, so i cant say for sure on the mainstream cpus.Quote:

Having no Vcore option in BIOS does limit overclock, but i've seen E8600 on P5B-Dlx at 4GHz with 1.32V, that is Vcore that MBO automaticaly sets. No bad imo, but i would rather like to find fine balance between Vcore and clock.
If I get bored of waiting, I could always buy used E8400 C0. :) I didn't see any problems with C0 stepping. Still good for 3.6GHz @1.3-1.35V.
Ya i was using my e8400 c0 & its rock stable @ 4.2 on the p5b-d. Crunches 24/7/365.Quote:

My P5B vanilla is C2 rev. but I have crappy memory (can't go over 840MHz) so I'm limited with that. On the other hand, I'm not willing to spend too much on this build, prior to Nehalem release.
My testing seems to show that the P5B Deluxe completely ignores the tRFC setting from the SPD data within a memory stick. You can manually set it to a maximum of 42 in the bios and that's it until you get into Windows where you can adjust it higher with MemSet if you need to. If he's not overclocking then he won't have to worry about this.Quote:

Pretty much every combination of parts causes some weird issue but when you work around all the bugs and get things running decently, this old board will put a big smile on your face. All those new boards are too damn easy. :)
Edit: You might want to ask this guy about his E0 on his P5B. He seems to be doing quite well.

If I still have an account there I'll try to post a question.
I would not spend 250 ~ $300.00 on a 775 MB with LGA1366 around the way. I would get the CPU and keep the P965 board unless I wanted to go DDR3. I think the newer chipsets are only a refinement of old technology. With a small memory performance improvement. And, I guess PCIX 2.0.Quote:

I want the Tri channel Bloomfield board and the cheaper Bloomfield 4 core w/ hyper-thread CPU 2.66 MHz.
After running a Quad CPU for a while, I don't think I will have anymore dual cores on my #1 PC. I have 8GBs of memory. And, I can't ever access all of it (in testing) with out the CPU maxing out (Vista 64). So, I will go with the 6GB Tri Channel.
I just think it is a bad time to spend top money on 775 technology.
Also, I would not buy any DDR3 because of the volt questions for the i7
Wow, quality DDR2 at a great price right now. I bet DDR2 will never be this cheap again.Quote:

I was wondering if the 1232 and up bios' give a better Max OC or if I should upgrade to a 8500 e0 and go from there
Thanks
1236 is the latest, im going to try my E8500 E0 in my P5B before I put it in the new moboQuote:

Hi again guys
I'm thinking about getting this (GA-EP45-DQ6) board cause I can get it relatively cheap, has anyone got any opinions on it?
It would be replacing my P5b deluxe.
What sort of overclocking capabilities does it have?
Better or worse than the p5b?
X-Bit Labs sure like their GA-EP45-DQ6 that they recently tested.
http://www.xbitlabs.com/articles/mai...-ep45-dq6.html
Looks like there's lots of potential there. If you're only overclocking a Dual Core then you probably won't see any difference when it comes to overclocking but with a Quad I'd rather have the DQ6.
Looking forward to see someone getting an EO running on this mobo... I have a mate that wants to upgrade but he's comfortable with 3.6-3.8Ghz region so 400FSB would be enough on an E8500
friday I get my E8500 E0 and well put it in my p5b dlx :up:Quote:

cuz the P5Q has 16 phase and RAMPAGE FORMULA 8 phase right
cuz for CF the X48 is the way to go but i want more fsb on the Q
Well, last night somethin' happened. My P5B-D is in my secondary box that I use for DL'ing, rendering and burning stuff. My main is for gaming.
Anyway I just had the P5B-D sitting idle and all the sudden heard this "pop!" and smelled smoke. Looked inside and a capacitor blew it's wad all over the place.
It's kinda sad to see the ol' faithful board go. Many good years it has served... I bought a P5Q-E to replace it. Hopefully I'll get a couple more good years out of it.
So, that sad, I guess I'll never be checking this thread anymore. Awww. :-(
@Dom7184
Well my P5Q dlx did 500FSB with the QX at 8 multi, but temps were way higher than with 10 x 400 or 8 x 450... so I opted to stay at 9 x 450 with 1081 on the ram for daily use... My friend ordered the E8600 so I hope it will run otherwise he will have to buy another mobo...
500FSB Quad screenies in the link :
P5QDlx 500-1200prime.jpg
well im not asking for prime stable :p: more for benching cuz the X3350 i got is x8 so im still looking to go with a P45 or X48Quote:

and make sure his on the latest beta bios ;) its supported
Core 2 Duo E8600 (3.33GHz,1333FSB,L2:6MB,65W,rev.E0) ALL 1236beta
True, its supported, but does it lack manual Vcore option? :)
:confused: no why would it :rofl:Quote:

If you say there is no problem with Vcore, then ok. Somebody posted E8500 & P5B-Dlx OC thread, there is also everything ok.
It seems that on some places everything works fine, but somewhere doesn't. Strange.
well i get mine friday so ill post if it works it should the X3350 isnt on the list and it works but for sure friday E8500 E0 via UPS :D
well it works but you set your fsb etc. then reboot then set the vcore cuz with me the 1st time its auto but the 2nd time you can set itQuote:

if I try install ATItool (for OC set profil 2D-3D-2D)
run atitool, pickup MHz for core, save, than have on my display white-black wiev
that means that cannot use ATItool, why :confused:
RT I dont like
well on my 9600GSO it goes to 2D on auto and I use RivaTuner for OCed 3D clocksQuote:

It only boots now with junk generic 1 gig stick when I put

I have tried all sorts of combinations and nothing
Once in a BLUE moon I somehow get luckly and get it to boot with 4 GB then the rig runs 24/7 for months no problems at all
but anytime I have to cut power say to vaccum the room or something im F*&#ED
Even a shutdown in windows then hitting power button on tower causes me to have to fight a damn war to get this board to work.
Why is this damn thing marketed for overclockers then won't boot with high performance memory WTF ASUS WHY
Can anyone help please or give good advice on how I can get it to boot.
What do you guys do to get this to work?
I just ordered the OCZ reapers that was posted on last page 2X2GB for 60+$ seems awesome
I hope this picky bastard will boot the OCZ when it arrives.
my settings in bios

all two same
try 0.26 that what I use in XP 0.27 I use in VistaQuote:

I had mismatched modules, one Ballistix and one Team that I thought was causing part of the problem. I kept a 512MB DDR2-667 stick handy for emergencies to get it up and running. I have no idea what the exact problem is but I did find a few things that seem to help. This post and a few after it might give you some ideas:
http://www.xtremesystems.org/forums/...postcount=4953
Good news is that my new OCZ 9200 2x1GB Reapers have been working great. No issues at all. With my previous modules I created some SPD settings and burnt it to both modules and it seems to have helped but I haven't been using them lately so it's hard to say how much of an improvement I got.
Even so, there are some settings that this board just doesn't like. Getting my FSB up to 500MHz x 8.0 or 533MHz x 7.5 has made things more reliable. Some boards don't like to overclock and this one doesn't like to run at default settings. I don't understand that logic but I can't complain lately. It also likes the memory now when it is up to DDR2-1000 or DDR2-1066. My Reapers can't go much beyond that without having to crank up the voltage so I don't bother.
You should try dropping your multi and then bump your FSB up to 500MHz or so. I'm not sure if the 65nm chips will like this but the 45nm CPUs love it. DDR2-800 CL4 memory gives better performance at DDR2-1000 CL5 and needs the same voltage. My Team and Ballistix are both DDR2-800 but on this board they run at a very similar maximum speed as my 9200 Reapers. The Reapers need slightly less voltage but that's about it.
Let me know if you want to try my SPD settings on one of your Ballistix sticks. If it doesn't work any better you can always go back to your original SPD settings as long as you saved them before and you can ever get your board to boot up with one of your other sticks. When testing I was shoving memory modules in while the computer was running. Windows didn't understand what was going on but the SPDTool program would recognize the module so you could burn some new settings to it and try again.
Dom7184: If you've got your FSB up to 580MHz, you sure don't need my help! I was using the P965StrapTweaker to get a little extra performance out of my chipset but at 580MHz, this tweaker might be too aggressive and your board might lock up and need a re-boot. Your memory bandwidth numbers look pretty impressive as is. I think my E8400 C0 also needs a second boot after a CMOS clear before the CPU voltage options magically appear. After that, it's open season with the FSB. :up:
