0908? Works well for me.
I had a $20 discount coming from NewEgg and needed a board fast, and cheap ;) They had the "vanilla" as open box for $89, I grabbed it and got it for $69 with the discount I had for them screwing up my last order.
I did all the vmods except for vcore, didn't have a 100k vr. Without mods the best I could do was boot at around 420fsb, my ram just wouldn't run any faster at 2.1v. After the mods with vdimm at 2.35v, vdoop set so I get exactly what I set in bios, and vmch and fsfb at 1.45v, I can now boot at 500fsb and it's at least superpi stable.
I got this 6700es to 4.6ghz on a DFI 975 board, it benched superpi 1m at 11.2sec. I want a sub 11sec pi and am pretty sure I can get it with this board (I'm insulating it for some dry ice runs), I only need about 4.63 to get sub 11's.

just got a P5B 0806 and E6600,
running at 3.4ghz ( 378*9 or 425*8 both stable )
3.45 fails prime after like 2 hours and 3.5ghz freezes on prime
vcore = 1.6 ( 1.5 idle 1.49 load)
vdimm 2.1v Geil 400mhz 4-4-4-12 @ 425mhz 4-5-5-12
60 degrees load
superpi 1mb 15 seconds exactly
problems im getting is in cpuz 1.38 it doest show all my mem timings, like command rate is greyed out and has no number in the box so i dont know if im running at 1T or 2T
how do u do any of the vmods
I just modded this board to allow me more vdimm, but unable to find Northbridge voltage adjustment, does this board even support NB voltage adjustments? :S
vMCH :)Quote:

Got it, thanks man, will be trying it out soon :D
do u have a link
new p5b ,vcore and vdimm mods done :p

would you recommend this mobo to someone who needs most of all a reliable and stable system?
does this mobo overclock good enough (around 450 fsb) without any mods?
will i need a chipset fan around 450 fsb?
thank you :)
I have the C1 Chipset and it does 450 easily without any mods
do you have to active cool it or are you with stock heatsink?Quote:

no 2.1 max, u need a mod, if u can afford a p5b delux then get it otherwise its still a good board
would you characterise it as stable/reliable or should i better go for the ds3 ?
I would go P5B vanilla over DS3, it's a great board.
Yup, love this one to bits! Cheap as chips too and overclocks like a MONSTER when vmodded. It's pretty damn good when stock too though, only thing limiting it is the lack of vCore (though that'll be the same on the DS3 too afaik)Quote:

Well, the Biostar seems more attractive to me then - especially after the new BIOS update.
It's wierd, because I thought this was kickass fsb-clocker; everyone was doing like 450 fsb :o
So with the new 1007 BIOS, what does it mean by "suuports 4X DIMM"?
I've had trouble in the past running 4 modules in the board (got all kinds of system restarts and shutdowns). Eventually ended up selling the other 2 sticks...Does this mean it can now run 4 modules reliably?
Thanks!

Mine is at 450 stable right now. Gonna research my ram a little more before I push it. It's ddrs 800 ram and I have it running at 900 stock.
It will actually boot up to 800 but fails pretty hard when testing it.
What exactly does fsb termination voltage do? That might be the problem.
I know this clock isn't a cpu wall. Its motherboard or ram.
Has anyone had problems running 4GB of ram (PC6400) on this board? I had troubles running 3GB, but thats because I think the timings were a hair different (both made by Corsair, and both XMS2, matched pairs - one 2GB pair, and one 1GB pair). The board didn't like the mismatch apparently..
I was thinking about getting another set of 2GB modules to run with the 2GB pair I was left with when I ditched the 1GB pair... What do you all think?
Thanks!

i hit a wall at 3.15 ghz then i put FSB termination at max 1.45v and now i can boot 3.5ghz and 3.4ghz stable at 425x8=3400
Hey all, I just wanted to post with some great news. I just got my p5b vanilla in from newegg. Immediately put the hr05 on the nb, and put some thermal compound on the sb. Then booted up and went in bios to see what was there.
Here's the great news! vdimm goes all the way up to 2.45v!! vmch goes all the way up to 1.77 (1.7_ I think it's a 7). vfsb goes up to 1.45v. There's adjustments for vcore southbridge (pcie/sata) as well as vich.
I was able to boot with everything on auto except for 1.4v vcore and 2.15v vdimm at 8x400. However, for some reason, g71gs was stuck at x1 instead of x16. I did some fiddling and toggled the force x1 a few times as well as brought vmch up to 1.55v (didn't bother with the 1.40v one since I remember on the ds3, it would be finicky with cold boots if vmch wasn't held at 1.55v), gave a slight bump to vcore_sb (since I'm running pcie at 110), vfsb up to 1.4v to match vcore. So far, it looks great. I love it to death over the god damned ds3.
The only thing that needs to be worked on is vdrop and vdroop. I understand pencil shading for vdroop should fix drop as well depending on resistance, correct?
I'm setting 1.40v in bios, seeing 1.35v at idle, and 1.30v at load. Good lord!! Can't wait to get my new psu in so I can try for 3.6ghz again. I was almost stable before, but it was pushing the ultra vpower 500w too hard. It would give out harsh electrical burning smells under load at 3.6 and eventually lead to instability.
edit: vdimm above 2.1v is not real. goes back to 1.8v
Hallo a friend of mine have a problem,after a lan he came home and his p5b was dead.in the morning it starts, but only the fans and leds, whith one memory in. He says the leds blink like crazy.anyone have a idea?
wat u talking about vdimm only goes up to 2.1 not 2.45
also with the new i think its called 1102 bios when u load a OC profile then in jumperfree configorations u see a new voltage setting called VMCH or IHC or ICH or something like that but its da chipset one, not sure if its south or north but u have only 2 options, 1.0 and 1.25 (not very high V, how high does it go on the delux), but if u overclock normally dat setting is not there, it only appears if u flash new bios and load a OC profile
Ricky, that's what I'm trying to say. I understand that normal p5b vanilla's only go up to 2.1v on the vdimm. Mine has settings up to 2.45v for some reason, although settings above 2.1v don't work. I'll take pictures sometime.
Also, that's interesting about vICH only showing up after you load an OC profile. I always have vICH (although the 1.0x volts and 1.2x volts). yes ich is southbridge.
I also have vmch (northbridge) that goes all the way up to 1.70v.
I've got a few more voltages too.
yea but when i did the ICH on 1.2 it doest boot and i have to reset cmos
but i dont have mch and 2.45 on dimm
I've never changed vICH. Didn't see the point. However, I do have vMCH up at 1.55v, and it seems to be making a difference. The occasional cold boot bug is gone. PCIE is always at x16. I can get up to 466fsb easily (ram limited currently).
Guys, I have a Asus p5b but i can't set the command rate
I can see the options to set memory timings but not command rate in BIOS, is there any such option in the BIOS, CPU-Z shows the RAMs running at 2T, i want to set it 1t..
Regards,
yea same here cpuz says 2T
ZIDDEY PLZ TELL US HOW U GOT vMCH voltage option
i can get vICH but it wont boot so i have to reset cmos
You cant set 1T with this board afaik.
Ricky, unfortunately, I think it's because I've got a new revision of p5b vanilla and lucked out to have vmch.
http://www.xtremesystems.org/forums/...d.php?t=134157
It's not called vmch. It's called nb vcore. Same thing.
Also, I tested the vdimm settings on my p5b vanilla.
2.00v: 2.08v
2.05v, 2.10v, 2.15v: 2.12v
2.25, 2.30, 2.35, 2.40: 2.37v
2.45v: 2.55v.
I loaded a saved profile in my bios but there were no new voltage options. Perhaps this is only available on some revisions?

Just an update: I have reached 520FSB with my P5B vanilla, which generates 3640MHz from my e6300. I ran the SuperPi Mod 1M in 15.985 sec. The Crucial PC6400 memory latencies are 4-5-5-12.

what i dont understand is my E6600 at like 3.3ghz and ddr 850 ant 4-5-5-12 can get like 14.999 seconds and ur 3.65 and ur ram is probably faster than mine gets in the high 15'teens
you've got 2mb more cache on him :)
yep, SuperPi likes the 4mb cache processors. The 520FSB was just a test and I ran a few programs, but it was too hot for everyday use @ 1.44 vCore, I believe. I have backed off to 470FSB @ 1.30v (3300MHz) and it runs much cooler, but the computer is 1.5 sec. slower in SuperPi 1M...
Is anyone running their P5B's with all 4 memory modules full?
I just got a second pair of 2GB Corsair DDR800 and plan to install them tonight, which will make 4GB total. I was told by RAMGUY at corsair that running 4GB of memory at the default 800MHz would still be too much on the memory controller of the board, and he recommended that I lower the memory frequency if I attempt this.
Now, I am running my E6400 @ 400fsb (3.2GHz), which appears to be "moderate" for an overclock - at least compared to other users in this thread ;)
Due to this overclock, I am already running my memory at the 1:1 divider - I wanted to keep my memory at default speed, as I was afraid of instability if I tried to go higher...hence, this nice round number of 400MHz FSB. I figured that the increase in FSB from 266 to 400 would be placing more strain on the memory subsystem anyway - why stress the modules as well, right?
Since I can't go any lower on the memory divider, should I be concerned that this will be too much stress? I've also heard of people complain that 4 full slots results in machines that won't even boot...
Thanks!

Ok, well, it looks like I can't run 4 sticks in this board. I emailed tech-support at Asus about the issue, and they say my board needs replacing :eek:
Hopefully the RMA process doesn't suck... Does anyone know if they will send you a new board before you need to send your original back to them? I asked, but have not yet gotten a reply... here's to hoping...
-Ryan
I think your computer should work fine with 4 ram sticks, but I don't think you can o/c as high on the upper end. I would think 400FSB should be fine. There was a problem with Windows XP which couldn't handle 4GB or ram and would recognize only 3.2G or whatever. Vista solved that problem.
When you RMA an item, usually you have to contact the RMA dept and get an RMA number. Then you send them the item... then they either fix it, or send you back a new one.
how to i find out my chipset voltage, in bios i only have cpu temp and motherbaord temp, but i dont think dat is the chipset/northbridge temp

althoguh instead of using the top of the cap, I'd use a known ground.
Yah, these r the newer revisions...Quote:

also anyone know how to find out chipset/northbridge temp, i got a motherbaord temp but dunno if its the same thing
I made a different thread documenting my findings.Quote:

2.10 and 2.15 settings both are the same, and I measured effective 2.12v. aisuite shows 2.10v, although it just shows bios setting instead of reading.
All further settings from 2.25 up to 2.40 are measured to be 2.37v. Then, the final setting of 2.45v is actually 2.55v. All settings above 2.15v result in aisuite crashing on load, because it doesn't know what the hell is going on.
Vmch, stock 1.25v actually gave me 1.30v. Then, the next option, 1.40v gave me 1.50v. Then, 1.55v gave me 1.60v. I didn't test 1.70v. That said, it seems that my p5b vanilla doesn't clock well at all, and doesn't like going much further than 450fsb stably. Extra vmch doesn't seem to help.
I didn't do vfsb measurements, but as I understand it, later bioses bring vfsb up to 1.45v, which is same as what this board offers.
I don't believe there's a sensor integrated in the p965 chipset. So if you want a reading, get a diode to place near the core.Quote:

Then again, in bioses I download straight from asus, they don't seem to be locked
Well, I initially was going to go through Asus's RMA department, but then realized that newegg has a 1 year replacement policy. I figured that would be much faster, as they send the replacement via next day air :-).Quote:

On the board I just in, I would get constant blue screens in Vista. As soon as I would go down to 2, it would work fine. I think it may have been a bad memory bank or a bad memory controller... who knows... I just hope the new board does not have the same problem.
BTW - since I have Vista64 Ultimate, will replacing the motherboard require me to re-activate? Or is the install tied to multiple pieces of hardware, and it only triggers the re-activation if several of those change?
Thanks guys! This forum is great!

Ahh.. I see...Quote:

I like the board... cheap n good... :)
It looks like the circuitry in the p5b vanilla isn't all too good. I think there might be too much noise / leakage in my board (rev1.04g). I've found that despite what vmch I give it, it won't go stable past 460fsb. And at 460, it's stable at 1.25v (actual measured 1.30v). But beyond that, not even 1.60 would help.
Then I noticed that when I had vmch up at 1.60 and didn't have a fan connected to cpu1 header, aisuite would register 42rpm. If I have vmch down at 1.30v, it shows 0rpm.
I don't mean to spam or anything, but this is simply too huge of news and I figured I'd try to spread the word as fast as possible. I noticed something interesting yesterday. When I had misc. voltages bumped up beyond stock (vmch at 1.6v for example), I noticed that even without a fan connected to the cpu header, I'd get an rpm reading of 42. I figured this must have meant there's a lot of electrical noise in the motherboard. Also, I noticed I wasn't able to pass beyond 460fsb stably, and at 460fsb, I could use all stock voltages.
So that got me to thinking about what spread spectrum did. I've always been told to turn it off and always have. But after thinking about it, I decided to turn it on and try fsb500 with all voltages at stock. Holy mother :banana::banana::banana::banana:ing :banana::banana::banana::banana:. It posted. I reset it several times (at 460fsb, it'd randomly not post when I had spread spectrum disabled) and it came one each and every time. I'm running memtest #5 and it's passed 4 iterations already. This is simply unbelievable.
My p5b (vanilla mind you) which has never seen beyond 460fsb despite misc. voltage bumps is now sailing at 500fsb with stock voltages across the board.
Welcome to the 500 Club ziddey! Amazing that Spread Spectrum did the trick. I thought that was for some European magnetic disturbance, or something. :)
Just curious, when you say 500FSB at stock voltages, is that "Auto" or standard? i.e. 1.28 vCore, 1.8 vDimm...
Well, I set them all to the lowest values. 1.20vfsb, 1.25vmch, 1.5vsb, 1.057vich, etc.
However, although that let me run memtest86, windows wasn't stable.
I bumped to 1.30vfsb, 1.40vmch (actual 1.50v), but it still wasn't stable. I then added 1.6vsb and 1.215vich and so far so good.
I've got my vdimm pencil modded so that stock 1.8v gives me 2.18v.
wat is spread spectrum anyway, if it helped u got 500 den y do people say turn it off, will it help me get 425fsb with my abit board if i turn that off too ?
only way to know is to fiddle with it.
spread spectrum lets the frequency wander a little in return for reducing emi. I figured I'd turn it on since I was noticing rpm signal when I had no fan attached. Sure enough it worked. I'm not sure why it's been said to turn it off all this time. I have read reports of it hindering o/cs, but in this case, it sure as hell gave me 40+ fsb. I tried 6x520 and got it to post too
Ziddey,
What speed RAM do you have? I have Corsair XMS2 DDR800 (that I keep at 800Mhz when I o/c to 400Mhz FSB). How do you run at 500MHz+?
Thanks!
-Ryan
I have ocz8800. It uses d9gmh chips. It's specced at 1100mhz 5-6-6-15 2.2-2.4v, but it's not all too impressive. Eitherway, for the time being, it looks to be working well, although at weak timings.
At 400fsb, you can run 500 ram with 4:5 divider. I'm at 500fsb so I'm 1:1

Anyword on overclocking ability or new OC features/options?
nice, I'll give it a shot.
hmm add new ucode. wonder if that's just for proper string detection or if it means 1333mod for 1066native will work now
edit: flashed on. seems more or less the same. don't see much differences so far
any new voltage options
nah, looks to be similar. I flashed from the bios so I wouldn't lose some data. I was at 8x400. I rebooted and it didn't post so I figured it was going to yell failed overclock at me. I remember it happening with an earlier bios flash. So I flipped the psu off and waited for discharge (nonvaginal) and gave it a go again.
Boots up at stock freq, claiming overclock failed. I go directly from 266fsb to 467x7 and reboot. It rebooted without first false booting, and worked! Never happened before. Usually, if it didn't false boot first, it would get stuck and not post, and I'd have to hold power. On next boot, it'd post at 467 no problem. I haven't tested further to see if symptoms are any better yet since I had things to do.
Voltages were the same in the bios, although I had 1.04g to begin with and had all the extra voltages.
If you use amibcp, you'll see exactly what the voltages are. Not all function like they're supposed to though, just to warn you.
I've noticed that when you view the bios you download, the options are all shown to be "shown" even when they're not. Maybe someone who knows a little more about amibcp/mmtool could figure out how to unlock them.
Just a little tidbit. From looking around in the bios, there are some things seen in there that are only available in the commando, namely doing with ddr driving strength iirc. PErhaps if ami modding is possible, and someone shows enough interest, it'd be possible to rig up something good.
I don't notice anything different about the bios. No new voltage options or any other changes.
I tried to o/c, and the mb went up to the same 525FSB = 3,675MHz (E6300). Then crapped out at 530FSB and Windows would not fully load. I did notice on the reboot after a failed o/c, it rebooted by itself and did not require the usual power supply shutoff to reboot. Perhaps this is a new feature of the 1202 bios?

If that part is correct, then what exactly is the procedure to add the shading? Do you simply start drawing on top of the resistor, coating it in lead?
Thanks!
-Ryan
voltage is static; it's current that can increase. yes, you just take a pencil and shade all on top of it. you can reference http://forums.anandtech.com/messagev...readid=1847758 for more info on pencil shading. Do take before and after readings with dmm. Also be sure to blow area (canned air preferably) to remove excess powder from the area.
Ziddey, since you seem so knowledgeable on this stuff - I have one more question, if you don't mind.
Is there a way to monitor the temps of the Northbridge chipset? When overclocked, I can't even keep my finger on the heatsink longer than a couple of seconds.
So, I added an active cooling solution (I strapped on a nice fan to the stock heatsink), and it seems to be running much cooler (I can keep my finger on the side of the heatsink, and it's just "warm" to the touch). However, I would like to know the temps it is running, that way I can decide if I need something a little more serious.
Currently, Im running AsusProbe 2 with Vista 64. The only other monitoring software I've tried have been Everest and MBM5. Everest caused problems, as it kept reporting the CPU running at 232F (which it wasnt), and when I would reboot, the computer would refuse to start, claiming a CPU temp overage - I would have to kill power to the motherboard for a few seconds to clear the issue, and once windows rebooted, it was reporting normally again at 105F. Probe2 never has this issue.
MBM5 doesn't seem to have this particular motherboard listed in it's menu, so I can't even get that one to work.
Any other ideas for a software that will work with Vista 64 and monitor the NB temp?
Thanks!
-Ryan
i got to core 2 boards i cant remember now but i remeber one of them had a temp monitor that said something like PWM which i assumed was the chipest
i think the zalman is the cheapest and best and lightest chipset cooler availible
http://www.zalman.co.kr/eng/product/...x=200&code=014
i have 2 allready its like £5/$10
AFAIK, the p965 doesn't have an onchip sensor, so the best way to get a rough idea of what it's running at is to put a thermistor on the heatsink.
I dont think it does either, has to be measured with temp probe. With active cooling it should be fine as long as you dont go volt crazy.Quote:

I am stuck at an FSB wall at 400 fsb... I tried everything and it still won't go over. Anyone else have an fsb wall at 400?
i should go past 400
try FSB termination voltage, worked for me to get above 350 FSB i think, was a long time ago
also check ur ram speed is not to high and ur ram voltage is not to low and ur ram timigs are not to tight
Right now my E6300 runs 100% stable at 500 w/ 1.45vcore (board is unmodded).
I'll see if it posts with spread spectrum on and if so see if the voltage will lower.
If you're looking for a decent value with C2D via overclocking, I'd grab an Abit IB9 and an E4300 or the upcoming 84usd E2160 to try for 3.4-3.6GHz. You're starting with a 9x multi and don't need a huge FSB for a decent OC.

I used to have a o/c wall at 350FSB with my old ram. But with my new Ballistix PC6400 ram, it does 470FSB at stock voltages, with the same settings.
So, I don't think, comrade, your Ballistix 5300 is the problem. Those are Micron D9 chips and probably the same chips that are on the expensive PC1000 modules (but perhaps binned?)
I would make sure your ram timings are at default (ram spd enabled in bios) when trying to o/c. You can tighten them later after you find your max. FSB.
At 400FSB, I think you may still be at the 2:3 ram divider, but at 401FSB and above, its 1:1, where it is much easier to o/c.
I would try 410FSB with the cpu voltage boosted to 1.45 volts, (which in reality may be only 1.38 volts, considering the vdroop of these boards.)
Then hopefully move your way up in 10FSB increments up to your max. o/c. Voltage will have to substantially increased to get above 490-500FSB. I'd watch your temps carefully for any sustained usage over 500FSB.
My system runs stably at stock voltages at 470FSB (Cpu 1.3875v in bios, which is 1.32v at the cpu), which equates to a 3.3GHz C2D. But this system was a dog with my old ram.
I reached 525FSB with the bios cpu voltage set at 1.55v, the memory voltage at 2.1v, and the FSBterm voltage at 1.45v maximum. All the other settings are on Auto. This o/c caused extremely high cpu core temps and other parts, I'm sure. But at 470FSB is cool, stock and stable.
Spread spectrum did nothing for me. Same system stability. Orthos started failing after a few hours like it normally does.
Thanks man, but I tried loosening the ram, and setting it to default, I am 100% sure it is not the ram, my ram has the D9GMH chips on it. I tried CPU voltage at 1.45V and still nothing. Anything above 400 the pc won't boot into Windows. I hate this board.Quote:

I used to have a 1.03G P5B, and I had to have max vdimm to boot into windows on my 8x400 (3.2GHz) overclock. I then ended up getting a replacement 1.04G P5B, and the system would not boot into windows unless I had my vdimm set to 1.9v. Go figure...

I have the 1.03G and I have my ram at 2.1VQuote:

Bought CORE 2 DUO E6600 for my P5B today, replaced celeron 2,53 and started having problems with WinXPSP2.
Here details, first boot ok winXP loaded, everything seemed to work, run game cossaks 2 it crashed PC restarted. Here all hell broke lose. WinXP offered me to start in save mode few times restarting PC as I tried to proceed. When I succeeded to load winXP windows explorer kept crashing and freezing.
To make it short I updated to latest bios 1202, and reinstalled WinXP (installation was horribly slow). Still problems, reinstalled winxp twice.
Upon restarting freshly installed Win get this message "windows could not start because the following file is missing \windows\system32\config\system
you can attemt to repair this file by starting CD..... (restarting PC helps to get to WinXP desktop)
I'm starting to worry I got defected CPU
Please any help appreciated.
Vasilii.
hmm not sure, maybe load bios defaults coz those cpu options may need to be changed, i dont mean the speed ones but like those other ones that have disable and enable, theres like 5 or 6 of them, just try reset bios anyway
hi.
can somebody test this version of SetFSB for P5B Vanilla ?
select the clock generator to ICS9LPRS552AGLF
download links:
http://cp.people.overclockers.ru/cgi...etfsb20b9e.zip
or Rapidshare:
http://rapidshare.com/files/29608287...20b9e.zip.html
please reply to me if it works. if not, please make a screenshot of "diagnosis"
No Function.Quote:

It seems problem was with RAM memory, I have two each 512MB, I changed one from socket 2 to 3 and in bios set ram from auto to 677MHz so far no problems.Quote:

I wonder what the max fsb this thing can reach compared to the striker's is
Does SetFSB 20b9e work correctly with checking Ultra?Quote:

@abo333
I did it before and it seems that SetFSB 20b9e does not work for P5b...
Hmm..., ThanksQuote:

They are all on the ASUS website..:stick:
Theres nothing for the chipset.......Quote:
