Asus P5E3 Premium Wi-fi-AP

Hi All,

Just abandoned the Striker II Extreme for this board. This ride hasn't been all that smooth either. I guess I'm just not used to motherboards having stability issues at stock settings.

Specs:
Intel Q9450 w/ Thermalright Ultra-120 Extreme (no OC yet - Stability Testing)
GTX 280 SLi (eVGA)
4GB Mushkin 1600 DDR3 7-7-6-18-2T (WinXP 64-bit) - 2 x 2GB
Asus P5E3 Premium - BIOS 0505
300GB Velociraptor
Creative X-fi Titanium PCI-E
Thermaltake Toughpower 1200W

All newest drivers available for all devices.


Symptom:
Computer seems fine when I get into Windows. But every 5-10 reboots, I get a random BSOD while booting into Windows. It's not the end of the world, but makes me suspect something is wrong.

BSODs have so far cited:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (and lists atapi.sys)

and (separately)

BAD_POOL_CALLER

System passed Memtest for six hours, ten passes. And that was with the timings suggested here @ DDR3-1333 (they're rated at 1600) and vDIMM at 1.84v. But I have since set it all back to Auto

Current BIOS Settings:
CPU Ratio Setting - 8
FSB Strap - 333
FSB Freq - 333
PCIE Freq - 100
DRAM Freq - DDR3-1066Mhz
DRAM Comman Rate - 2N
Dram Timing - Auto
. . . all auto until. . .
DRAM Voltage - 1.86v
LLC - Normal
CPU Spread Spectrum - Disabled
PCIE Spread Spectrum - Disabled

Summary:
Getting BSODs at stock settings with nothing fancy going on makes me nervous that I got a dud board. Is this the norm? Should I be considering nudging a couple voltages up? Memtest passed at more aggressive timings and frequency than current. So I'm suspecting the NB or something might just need a bit more juice. But if BSODs at stock are an indication of a lemon, I'd rather save my time and RMA quickly.

Thanks!

Hey there HurinThalion, with 4GB ram and where you are running, you may need more NB voltage. I would give that a try first. I am at default with my CPU at FSB 400MHz multiplier 8. I have NB set at 1.43 currently and suspect that I may even need a bit more at current settings. Let us know how things go. I am by no means a guru so let's see what others have to say as well.

Just tried bumping my northbridge up to 1.39, and then 1.43. Didn't have any effect. But it was a good suggestion. It's what I was suspecting too.

It may however, be an issue with the newest drivers for either the Realtek or the Marvell network controller. Testing that now. I've disabled them both and am just restarting over and over. Hard to prove a negative, but I'm hopeful that I'll be able to restart 15-20 times without the BSOD. Haven't been able to do more than ten at a time without one.

Well, with both NICs disabled, I had no BSODs after twenty reboots.

With the Marvell NIC (only) enabled, I got no BSODs after 10-15 reboots.

With the Realtek NIC (only) enabled, got one BSOD after five reboots. Another one after three or four more reboots.

So that's still within the range of it just being bad luck or a fluke. But I've uninstalled the Realtek network driver that I downloaded directly from Realtek last night (v687 installation package). I just installed the ancient driver from the Asus page. Hopefully that will fix it. If not, I may have a bad network controller. Or I suppose the trend could lead me to something different altogether. But at this point, I'm thinking it is indeed a bad (new) driver from Realtek.

Edit: Well, older driver is still BSODing. Disabled the controller and will see if that fixes the BSODs. Though I don't generally like to have a failed component on my motherboard. Everything is connected. So if that's fried. . . what else might be fried? Booooo!

How many here are running with the Realtek NIC enabled on BIOS 0505? It's hard to believe that nobody else would have noticed this if my Realtek NIC is not actually faulty. Perhaps it's just a conflict with my sound card or something since the PCI-E X-fi Platinum is still somewhat obscure. Perhaps it's only the XP 64-bit Realtek driver? Bah, so many variables. I'll just disable the NIC and hope for the best I guess. I just don't like what this might mean for the rest of the board's components.

Edit again: It occurs to me that I probably shouldn't be saying "NIC" considering these aren't technically "cards." =)

Please keep in mind that 0505 is a beta bios which enables some overclocking options (like dos skews for ram) but is not certified to run perfectly in daily use. After an official version is available I have the feeling that you will not have that problem anymore.

No probs with Realtek here, this is the driver I am using:

0505 has been official for a few days now - you can d/l it from the P5E3 Premium non-wifi ASUS download page or the ftp.asus.com.tw site...

I was about to ask what OS you're running. Then I looked more closely at the border of your screenshot. :D

I've tried a driver both older and newer than that version. With no change. But it could be an issue with the XP 64-bit driver (and possibly some other factor like my sound card, video card, etc.).

So, it's time to install Vista a bit earlier than I anticipated. I usually like to get things all validated at stock on XP. But I want to make sure that there isn't a hardware fault here.

Thanks for the feedback.

I am looking at buying this Motherboard. I already have the OCZ platinum 1600Mhz 2x2Gb modules, and a Q9450. Want to get it up to 3.6Ghz or more. Good idea?

Guys please help! I really dont know what to do ... ive rma'd board/psu/soundcard and still have cracking and popping issues on both onboard and prelude soundcards ... guys at ocuk think it could be an earthing issue! what do you think?

Regards

Maybe you'd call it Earthed? Ahh, English in all it's forms.

OH MY F****** GOD! it turns out my pc is perfectly fine and always has been, I turnt my pc speakers of to use headphones and there was still popping and cracking, it turns out it was coming from my samsung 40 lcd which I use as monitor, mute the TV's internal speaker and EVERYTHING is fine, im so pissed off but at the same time releaved :E

Forgive me, but is that the Xeon Equivalent to the E8400? IF you are running the 9x multiplyer on the cpu (3.9ghz) there is a good chance you need more Vcore. I would set it to around 1.4v in the BIOS (don't worry, you will probably be able to back it off some later), also, you are pretty close to 1800mhz on your ram, and if you are at PL7 and have the clock twister set to AUTO, you will most likely need more NB voltage as well. I personally would set it to 1.6v for testing. If this stablilzes your system, you will be able to slowly drop your CPU Vcore untill you see instablity again. When I say slowly, I mean, first be sure that your system passes Memtest86, prime95, and maybe even OCCT for several hours. IF it does, then you can begin to drop those voltages, one at a time untill you see errors. Then go back uo 2 clicks for Vcore, and perhapse one on NB voltage. You will also need to test NB stability with some stressful 3D games,as a heavily loaded Video card adds to the stress on the NB. I personally like to use Crysis, since it stresses the CPU and Ram more than most games do.


Just make sure that once you believe you found stable settings, go back and start dropping those voltages, one at a time, so you know which one is reponsible for any changes in stability. You may end up need =ing alot more voltage than you are using right now, or maybe just a little, but it is easier to start high and work down. The voltages that I mentioned should be very safe for testing, and depending on your luck with your particular CPU and Board you may need even more. Just watch your temps while testing.

Soapman72 my NB is a crap, this do 1 month I try many setting and the board would nothing understand. I cannot put high memory frequency with a high cpu frequency. When I tell high it not very high...

Example

If I put my cpu at 3.48GHz fsb425 and 8x with memory at ~1160 this is prime stable
If I put cpu at 2.66GHz and memory at 1800MHz prime stable again
But if I put cpu 3.48GHz and ram at 1741 or ~1398 boot and crash after 3 minute

If I put in the bios more than 1.55 this not help ( I have try to 1.65 with 119CFM fan on NB) and this change nothing and with some setting is stable with 1.55 and not with 1.57 or 1.59.

If this can help someone for help me,


The x3350 is 24H OCCT stable 1.23V but only if I do CPU test.If I do mixte test or Ram test with ram at 900MHz 1 or 2 minute stable only.
My ram can take 5-5-5-18 1350MHz (not tested more) at 333FSB and is factory default 8-8-8-27 1800MHz

Thx for help again and if someone think it the time for do a RMA I will do it.

Edit:The x3350 it the 8X coef version and the bacth L806A744

Try 1.65v on the NB if you can put a fan on the NB. I use a fan myself, and it might sound kinda funny, but it used to be a Corsair Dominator ram cooler. It has (3) 40mmfans spinning about 6000rpms, and is nearly silent. The 3 fans neatly cover the entire NB heatsink and seem to do a great job controlling temps for me. I wish this board reported NB temos like the ROG boards do.....oh well.


I run 1.61v on the NB currently with my CPU running at 450x9 (4.05ghz) and my ram at 1800mhz 8-8-8-27-1N I run PL7 and the clock twister set to STRONG. On the 333 strap using STRONGER does absolutely nothing, where using the 400 strap there is a performance difference, but still no better than the 333 strap and STRONG. Any less is not stable.

I spoke to Corsair about their 1800mhz 2x2gb kit and they recommend on their website 1.71v NB voltage for that kit and the P5E3 Premium. They say that during testing, some boards will run stable with as little as 1.61v but some require 1.71v they also said that active cooling is a very good idea with these voltages. They also said, that ASUS should be the final word when asking if these voltages are safe for 24/7 use. When I laughed at their recommendation to ask Asus ANYTHING, they said that the boards they test on have been running for a LONG time at those voltages.

Just run a fan on the NB, and like me, hope that if the board does go out, it does so while still under warranty. If that makes you too uncomfortable, run the ram @1600mhz or run 2gig's since it will lighten the load considerably. It sucks that no one telle us it will be this hard to run 4gb and 1800mhz. I can't even imagine these boards doing 2000mhz 24/7 (safely) with 4gb even though there are 2000mhz 4gb kits for sale now.

Soapman72 Thx but Answer at all this question please , I am french and not sure if I understang 100% correcly.

1)You tell Corsair recommend 1.71V this is right, but Do you tell Asus tell is safe for 24/7 use ?

2)when you put 1.71 the board is under is warrantly or not ?

3)Can do you put the link of the place you have see a personnal from Corsair tell what you have write ?

4)And Soapman72 , if you have read my message, you have understang that , if I put more then 1.55V I am more unstable then 1.55.I have try 1.57 1.59 1.61 1.63 and 1.65 all with a Fan on NB a 119CFM fan.It not normale to have more instabillity when I put more voltage.

Exemple

success run 435FSB CPU 3490MHz Ram 1741(under below spec)

If I put 1.51volt to NB 13 minute stable of Prime 95
If I put 1.53 volt to NB 54 minute stable of Prime 95
If I put 1.55 volt to NB 9 minute stable of prime 95
If I put 1.57 volt to NB 3 minute stable of Prime 95 ...

Here is the link to the corsair page: http://www.houseofhelp.com/forums/sh...ad.php?t=54052

Scroll all the way down to the bottom.

ASUS is a JOKE when it comes to tech support. I have spent more hours on the phone with them than I care to admit, and they have never once given me any help, only bad advice that has wasted more of my time. I even RMA'd a board that did not need to be.

I also have seen what you are describing regarding less stability with more voltage. I think that your problem just means that something else is not where it needs to be. Not enough Vcore to run at the speed that you are trying to run perhaps?

H have gone down that road, spending alot of time tweaking one bios setting only to find that another is really the answer. If you are using only 1.3v in the bios for your VCORE, it is quite possible that you need more to run at the speed you are trying to reach. for testing, set it to 1.4v in the bios. You will not hurt the CPU, as this only results in about 1.33v when loaded 100%. Watch your temps to be sure, and set the loadline calibration to NORMAL, since the 0505 BIOS sets this to performance automaticly when approaching 450mhz FSB.

Good luck.


Oh, and if this 119cfm fan is 92mm or 120mm keep in mind, that if you place it right up against the NB heatsink, there is a rather large "dead spot" in the middle of the fan where not much air is being moved, and you may not be cooling the Nb as much as you think.

I will try for more vcore but I think I have already do it.My x3350 is 24H OCCT stable CPU test 1.23V at 3.6GHz but failed after 2 minute mixe test and Ram test. I dont think I need more Vcore for 3490MHz.. but I will try.

For the question can you answer please at each by yes or no for be clear ?

For the fan it a 120mm but not close from the NB 30cm behind and a antec spot cool are on it.

I cannot answer all of those questions to be sure. Asus will not answer them either. All I can say is, that I know how much Voltage I need to run my 1800mhz ram and I am giving my northbridge that much. I am cooling my NB with 3 fans and hoping for the best. Corsair will not take responsibility for any failed boards either. We are overclocking, and we take the risk unfortunately. I don't believe that as long as you are keeping everything cool ASUS should warranty the board. I am confident that I'll get my board covered if I have a problem, because after MANY MANY hours of testing, I am SURE that I am using the minimum required amount of voltage for my RAM, My CPU and my NB. I am even running the PLL and FSBT at their minimum voltages. The specs on the board say up to 2000mhz ram, if ASUS wants to start denying warranty claims for people running ram speeds that they claim their product will support, they better start putting some serious disclaimere in the manual.

I have try more Vcore and nothing more ...How many RMA you have do for this board model and can you explaine what Asus have tell to us during all your hours at phone ? this can help me is something is for know.

Hey everyone. I spent a good part of the weekend getting my system to run stable at default fsb 400MHz with 2x2gb ram. I had thought that I was stable but finally bought and tried playing crysis. My system crashes after a bit during gameplay. I then tested and am not superpi stable. I have made some success at trying to "dial in" the clock skew. I am currently at channel A2 delay 50 and channel B2 delay 150. I was able to run two full passes thru memtest 86+ v2.01 at fsb 455MHz with multiplier 7.0 Now, I put it back to fsb 400MHz and put in those skew values and still no success. My system crashes with superpi still. Any suggestions?

Ok, I must admit I have been a little afraid about pumping up the nb voltage too much. I had been at 1.45 with the failures and after reading again this page, I tried pushing it up to 1.61 to see if that would make a difference. Superpi now stable at 2M which I had not been able to do before. I am hopeful that the increase in NB voltage will be the answer. Too late to do much more today but tomorrow is another day.


A little more...
Ok, what's wierd is that when I ran the superpi 4M, prime95 was running (forgot to turn it off). It passed. Then I shut of prime95 and tried 8M and the computer crashed immediately. Any throughts?

Are you running loadline calibration? If you are set this to NORMAL. Bump the NB to 1.61v or even 1.65, and bump the Vcore some. You and I have the same ram, and the same board. You have a CPU that will place more load on the NB though, so 1.61 will be the absolute minimum for you IMO. You can always drop the multiplyer if you are worried about putting too mych Vcore to your CPU. You will still need to bump the NB and once you are stable you will need to bump the NB again when you try a higher multiplyer. Faster CPU speed means more throughput which means more load on NB.

My system is stable and does not Freeze/crash/BSOD I am sure yours can get there as well.

Man, I need to get to bed. It always is (just one more test) you know how it goes... I tried increasing nb voltage to 1.65 and set llc to normal. I then tried running the 4M on superpi and it crashed immediately (this had just worked at a lower nb setting of 1.61 and with superpi running at the same time). Thanks for the input. Any other thoughts? Also, I have not increased the FSB from the default of 400MHz. I can't even think about increasing it further until I can at least get things stable at FSB 400MHz.

What are you running for Vcore (as reported by CPU-Z or everest? What speed is your cpu running at?

Soapman72 , can you answer to my last post please ? I have news 2 hours 19 minute before crahs for 3490MHz and Ram 1741 but I have see my cpu voltage in load was 1.41 ... I have change the LLC Auto to normale.

Razmatazz I have the same board same memory and I have a Quad core penry to :D and a anothers same thing in common , I am not stable to lol. What bios you use ? 400FSB is easy if you tweak clock skew A2 B2 delay 200 for me.

I have BIOS 0505. I have left the Vcore at auto. I had thought that since I am running CPU at default speed, that auto would be fine. Voltage is at 1.216 during prime95. Should I set Vcore manually? If so what would be a good initial setting? I am skeptical that this will make a huge difference but would be willing to give it a go.

Also, should I just not worry so much about Superpi crashing the system if everything else seems to be working well? I would think that this program should be able to run on my system.

I run a dual core (E8400) and bois 0505. I have not needed to bother with clock skews for the RAM and you probably shouldn't need to either. Just make sure that the Vdimm is set to the specs that your ram maker recommends. It sounds like you have snough VCORE, but watch those temps. If you have NB voltage set to 1.61v-1.65v, you should be close.

If you still get a crash after 2 hours, have you tried leaving everything as it is, and setting the clock skews back to AUTO?

If that doesn't help. but also doesn't make it worse, than you know that playing with that variable is not the answer.

Vrom here, I would begin to increase FSBT and PLL, assuming that you left those on 1.1v and 1.5v respectively up untill this point. I would try 1.28v for Fsbt and 1.58 for PLL.

First, NO Program that other people can run fine should crash your system. Just in case, download a new copy of Super Pi and see if it runs on your computer all the way to 32 million.

I would try a bump in Vcore to about 1.28v-1.30v while under load this cannot hurt you, and may help as I have seen that for a given CPU speed, Vcore requirements may be slightly higher when running a lower multiplyer and higher FSB.

Next, are you still in the 1.61v-1.65v range for the NB voltage? I would try PL 8 if you are currently at PL7. You can do this by setting the Transaction Booster to MANUAL and selecting 8. Leave clock twister on AUTO

Let me know how this works.

Is Superpi Mod v1.5 the right one? This is the one that I have been using.

I tried bumping to PL8 without any effect. NB is up to 1.65. Still crashed.

This seems like a big change from NB 1.41 and PL7 which had run everything stable except crysis and superpi. (which is where I'm still at in terms of stability)
Is it the case that the system would need this much given the fact that I am running default cpu speeds and memory much lower then rated (1600MHz)

I'll give the increase Vcore a shot.

Thanks for the advice.

I have already PLL at 1.58 and 1.30 to 1.34 for the FSBT.If I don’t put this clock skew I just no boot...

Me what I would it a stable 24 hours Prime stable, When you tell that is stable, Razmatazz how many hours of Prime 95 you have run ?This can crash after 6 or 11 hours if you can run it 24 Hours it sure you cannot have problem.

Sectorz,


what kind of ram do you have? I had many, many problems when I first got this board that were related to OCZ Platinum 1600mhz ram. My board did not like the ram and I went through 3 boards and 3 kits of that ram with lots of weird freezing, BSOD's and crashing games. I got rid of that ram and now have 1800mhz OCZ Reapers, and the board has worked flawlessly since. It took me about 3 sessions running prime95 to find settings that work.


I agree completely with your comments on what truely means stable. Theoretically your system should be able to run prime forever, but I don't have that much time on my hands....LOL And yesa 24 hour prime 85 run with no errors indicates that it is pretty stable, but that is no gaurantee either. Isn't it possible to get an error after hour number 25 or 26? Of course. We could start a whole ne thread regarding what constitutes stable, but that sounds boring.

I will tell you that my system has recently run as long as 6 hours w/prime 95 no errors, 4 hours occt w/no errors and 10 passes on memtest86 with no errors. Could it error in 8 hours? Absolutely, but since I have not had one single BSOD, program freeze or crash, or any indication of OC weirdness whatsoever, I would rather just enjoy my system instead of using it to heat my house. It is summer here in Vegas after all.

I hope you don't reaqlly need to use clock skew adjustment to get your ram to run at it's rated speed. That alone is an indication that your ram will never work well in that board. If you are confident that you have adequate voltage for your NB and VCORE, and have also tested with PLL and FSBT at their lowest (non auto settings) maybe it is time to start RMAing your board or RAM untill you find out the source of the problem.

I ran OCCT for 1 hour with pass. No real long runs of Prime95 yet. I am not overclocked. I can run Superpi Mod v1.5 if Prime95 is also running. When I shut down Prime95 and run Superpi the system will freeze and I will have to restart. Any thought about this one? Weird huh?

Yes, weird.


Did you say that you have loadline calibration set to NORMAL? If it was set to auto, setting it to normal may have resulted in your CPU getting less VCORE, it did in my case at 450mhz fsb. Try bumping the VCore a couple of clicks in the bios and run super pi again. Are you currently at the minimum PLL and FSBT? Don't use auto, as that is not the minimum if you are running higher than 333 FSB, the board will automatically start raising VCORE and several other variables as you increase FSB, and it is better to set these items manually.

The I have start a RMA the board left my home tomorrow .

Yes, loadline calibration is set to normal and CPU Pll as well as FSB termination voltage are set to minimum. FSB again is at default of 400MHz. With Vcore set to auto, at load CPUID reads 1.216 I can run Prime95 and Superpi together with Vcore at auto. I have bumped Vcore all the way up to 1.35 with no change. Increasing Vcore doesn't seem to make any difference as the system behaves exactly the same way and Superpi won't run alone. This one has me really stumped. I was hoping that as I was able to "dial in" the clock skew some that this would help stability. Oh well, I'm going to try to further tune the skews and check Prime95 for a longer run. Any other thoughts?

I dont have he modded Super Pi, but in my experiance, running even a 32m super pi run is not as difficult load as running prime. What I mean by that is a computer can be "stable" enough to complete a 32m super pi run, yet fail prime95 after a relativelu short time, it is not usually the other way around.

I suggest that you run Prime 95 for now, and dont worry about super pi. Try to pay attention to which core fails, and how long it takes. If it is ALWAYS the same core, you may have a weaker core that may require you to play with the GTL for that core. I have been lucky as I have only needed to dial in the Nb Voltage and Vcore on my system.

Also, please make sure that your ram is set to 1.9v

Ok, let me share a little of my latest trials. I have found that clock skew does indeed make a big difference in being able to run my ram with a quad core in terms of stability. I have been trying to dial things in with memtest but have found that this has been very difficult to say the least. I then tried to dial things in via Superpi. If you read my earlier posts you would remember that I had not been able to run Superpi at all without crashing the system. I have tested each ram module seperately. I am stable between 300 and 350 delay skew in one memory slot and between 275 and 350 in the other. I have more testing yet to do. I am confident that this will solve my instability issues and that after I have my ram stable I will finally be able to begin pushing the CPU. To make things even more frusterating to me is that one of the memory modules is not stable at all for Superpi at any of the skew settings regardless of the slot. I already have an RMA in the works. The OCZ guys have again been outstanding to deal with. Will keep you posted.

Hey all - need some help.

QX9770 running at stock speed (3.2 GHz) on this (P5E3 Premium W-fi AP). Trying to use 1600 MHZ kits of DDR3 (I've tried a few at this point), which should be easy given the QX9770's native 1600 FSB.

So here's the issue...I keep getting an error on Core 0 or 1 after a seemingly random amount of time...usually between a few minutes and 8 hours.

Small FFT test works brilliantly for 24+ hours. So does OCCT (4 hours), SuperPi (32 million calculations), and Memtest86+ (multiple passes - done up to 20 some before).

But I can't get it fully stable on the Blend test for 24 hours, and it's bugging me. Suggestions? I've tried raising vCore just a bit, but haven't tried doing anything with any of the other voltages because I'm not sure what's safe to try them at...

Thanks for any help!

I could use some help here on overclocking my new E8400 on the P5E3-Premium mobo.

As far as I understand VID is the standard voltage the chip will run on when at standard speed. I guess my chip's VID was 1.18V @ 3Ghz (Q817A240; pack date 4-6-2008).

I already searched the internet for some basic settings to start from. The following settings got me into Vista64 but when I start orthos it already gives errors after app. 10 seconds. Would pls take a look at my current settings and give some advise:

CPU ratio: 9.0
FSB: 450
FSB strap: 400
PCI-E: 100
DRAM freq.: 1800
Timings: 8-7-7-25-2T @ 1.98V (factory specs are 7-6-6-24-1T @ 1.9V)
CPU volt: 1.425V
FSB temination: 1.3V
NB volt: 1.45V
Temps. idle: 42 and 36 (measured with speedfan v4.34)

Everything else is on auto including, load line calibration, CPU spread spectrum and CPU PLL voltage.

In my opinion these settings are way to high as compared to other E8400 users here on the board. However lowering one of these settings results in BSOD or no POST. Thanks in advance for the advise which is much appreciated!!!!

is your cpu even capable of 4050MHz at those volts? drop FSB back to 400, you cant just jump in and go for such a high o/c right away.

Ok, I think I know what the problem was because I set load line calibration to "performance" which differs tremendously in Vdroop. At this moment OCCT reports a flat and steady Vcore but without load line calibration (llc) enabled Vcore would drop sometimes with 0.03 - 0.04V. Hence setting the Vcore as mentioned to 1.425V without llc this results in an effective Vcore of app. 1.39V. At this moment I still have the same Vcore but the system runs at 450 FSB.

Soapman72, I have news :)

I have receive my board from RMA and now I have do a fast test and FSB 430MHz 3440MHz ram 2*2GB 1720MHz stable 4:20 hours for the moment (I will keep it in load for the night to have a 24 hours stable for have a base to push more after) with only NB 1.53v CPU 1.25V RAM 1.92V clock skwe 175 A2 B2 3/4 off setting at auto.I hope to crush minimum 450 of FSB this time I know my cpu can do it and the ram to.

That is great! It is a shame about all the time that you spent trying to get your system stable though. Hopefully it will go better from now on. Keep us posted.

Your settings sound about right. I was at 3.8ghz and 1800mhz ram which required 1.57v nb to be completely stable. 4.0 ghz requires 1.61v with the ram at 1800mhz 2N. If I run 1N it looks like I need 1.65v NB I am treading close to the limit when it comes to NB voltage. I may just run the command rate at 2N to save the NB.

The test have pass 14 Hours now.I will try 435 of FSB, before go to job always with 1/1 ratio.But for the moment I am in performance level 8 ram in 2T yhis is not good, but with my others board I have never successfully bench table more then 3490MHz and 1160MHz for memory and now 3440MHz and 1720MHz for memory.

Edit:This do 5:30 hours at FSB 435 3490MHz Ram 1740MHz same voltage of FSB 430MHz.

Someone can tell to me if if normale to have 50 degrée max on is 4 core with a penryn 3.5GHz and 1.23V reel with a watercooling 720
radiator ?

Edit 2: Error after 3:30 hours FSB 440MHz 3525MHz Ram 1760MHz 2*2GB always with NB 1.53V.

Edit 3: before go to sleep I start anothers test this time FSB 440MHz 3525MHz Ram 1760MHz 2*2GB but NB 1.55 and AI clock strong perflvl 7

Edit 4: 1 Error on core 3 after 7 jours 51 minute someone have idea what can I do for have this 24 hours stable ?I have shutdown the test after 12 hours stable on the 3 others core.

doe sthe NB get hot with 1.6V on it? do you need aftermarket cooling on it or is stock solution adequate? about to buy one of these boards.

Is anyopne using the Wi-Fi? for the pasts days i've been lossing the conection even thought it says i'm conected no data gets through.

I wish I could answer that. Ther bios on this board does not report NB temps, only a generic motherboard temp. I will say that I have had the NB voltage set to between 1.57 and 1.65 for a few months now, and all is still OK. I have had a Fan on the NB since I went over 1.6v. I am running 1800mhx ram (2x2gb) at 8-8-8-27-1N so it is wuite a load on the NB.

A question that's been bugging me... during Prime95 test, is there a problem having the 4 cores passing the tests not at the same time ??? I say this because I have never succeeded moving the cores through prime95 tests simultaneously.

And the most important.. is this behavior a symptom of an eventual collapse of one or more cores after some time during the test (which is my case, since I happen to notice all the time the cores - at least one or two of them - moving asymmetrically through the tests, and eventually one of them collapses after an hour or less).

Overall, the possible key to prime95 success is to bump up the cpu and nb voltage until prime95 gives me an 8hour stable system, or something else ??

My settings are

multiplier 08.5
strap 333
fsb 450
pcie 105
dram frequency 1801
cr 1N
ram timings 7-7-7-18
dram static read & dynamic write control disabled
On skew settings dram CLK dimm A1 & A2 delay 200ps and B1 & B2 delay 225ps
clock twister stronger
PL 7
And the following voltages
CPU 1.41250
GTL 0/2 0.64
GTL 1/3 0.68
CPU PLL 1.56
FSB Termination 1.26
DRAM 2.04
NB 1.57 (with a 80mm fan looking halfway down the nb)
NB GTL 1.67
SB 1.05
clock overcharging 0.90
LLC Normal
Both spectrums disabled
all rest at AUTO.

And under Advanced CPU Configuration menu all disabled except CPU TM Function (this one remains enabled).

Please guys, give me your lights !!! THANK YOU.

I'm very busy trying to overclock my new system. And I have to admit I had a pretty hard time on getting some decent overclock. I just read this page and saw some complains about the Q817 batch. Well, I guess I'm unlucky then cause my CPU has batch number Q817A240 (pack date 4-6-2008) with a VID of 1.25V (in Everest).

I have the following results at this moment which seem te be stable. However I have to admit that I'm still trying to find some better settings and need to finetune. I would like you to shed some light on my current settings and maybe give some advise which would be much appreciated.

CPU: 4Ghz (9x445 @ 1.43725V) (RealTemp, Idle: 40 & 36; Load: 54 & 50)
RAM: 1780 @ 1.94V (8-8-8-26-2T; specs are 7-6-6-24-1T)
NB: 1.54V
VTT: 1.3V
DRAM static read control: disabled
DRAM dynamic write control: disabled
CPU spread spectrum: disabled
PCIE spread spectrum: disabled
Load line calibration: performance (this setting seems to prevent much of Vdroop according to CPU-z)
All other settings are on auto

In my opinion the Vcore and NB are bit high. Moreover I'm not sure what the highest acceptable values are for these settings. Anybody has some guidelines? But when I compare my settings with other E8400 owners I get owned big time although my settings need some finetuning. Is this only due to a bad CPU batch? Any help would be nice.

Nick2006, just looked at your settings. I see you have clock skew delay channel A 200 and channel B 225. If channel A is closer, shouldn't it be the one to be slightly more delayed in order for signal to arrive simultaneously? I'm not sure that this will make a difference though. Have you tried to "dial in" things for each channel seperately? Are you Superpi stable? I found that I needed a delay of 275 to 350 in order to run Superpi without crashing. I am currently waiting in order to do more testing as I'm waiting for a replacement memory module.

I have try littil more voltage on the cpu and I have past 45 minute more for a 8:30 hours stable but error on one core after this.Ihave try to put 1.57v at NB and I have failed the test at 2:58 hours ...I hope this motherboard have not the same probleme of my old (more NBv = less stable)

SuperPI is stable (tried with success 1MB, 8MB and 32MB). Also Memtest86+ gives me a full tests pass with no errors. The only problem still remains the Prime95 (blend) test that keeps giving me a core error after an hour or so...

I really don't know which setting to touch.. Tried almost all settings.. For example, if NB gets bumped up even a notch from 1.57 Prime95 hits within 10 minutes. If PLL and FSB Termination gets bumped up from 1.56 and 1.26 respectively, Prime95 hits almost at the same fisrt 10 minutes. Tried to increase Vcore from 1.41250 one or two notches, and CPUID HW Monitor reaches over 80 degrees C on CPU cores (in all other "normal" cases the highest celsius degree is around 70 - 72, note that i use air cooling with a Scythe MUGEN), and Prime95 doesn't delay from crashing a core or two down...

I really don't know anymore which one to increase or decrease. Thought that more power through electric circuits can make them work better, but how much, and which circuit, u know...

Complete despair so far for my high-end system... :(

When I had the OCZ Platinum memory (4x1GB) I had all kinds of problems - similar to what you are experiencing now (I was not able to get up to where you are even at now however). It was definately a bandwidth issue for me (quad core and 4x1GB). Perhaps you may be able to "dial in" the skew for each channel (& memory slot) and see if that makes a difference. You would have to test each slot individually. Decrease CPU multiplier and increase FSB/DRAM frequency until you get errors in memtest86+ version 2.01 and then see if you can "dial out" the errors by hitting the right skew. This is a long and tedious process but perhaps might be able to help you achieve better stability. Interstingly for me it looks like Superpi stability will be able to help me dial in things and thankfully this does not take as long. Good luck.

Hey guys, can someone tell which the best divider for high fsb is? SuperPi 32M with 600FSB is only 1:1 stable :(

http://www.abload.de/img/600fsb-32m-02pi8.png

Edit: found the problem, board wont run CR 1T with 600FSB and bigger divider than 1:1

http://www.abload.de/img/600fsb-32m-03en6.png

i also have some problem with the dividers, but i never thought CR was the theif in the drama :)

having trouble getting ddr2000, i know the ram can make it but when im coming upto 1956mhz the board gets unstable and cant handle it with no strap avaiable..
gonna try CR2 later, how much perf do you aprox loose with this?

regards.

I've put my qx9650 back in this board with the 0505 bios. I can bench 470-480fsb now whereas I could only get a 1m or validation at that sort of fsb on DFI LT X48 T2R and Giga EP35 DS4. This board is a keeper.. Last s775 board I buy.

@ Chri$ch
Man that's freakin' nuts, 4.5ghz 32m with 1.3v! The E0 stepping really looks the goods.. 5ghz benchable on air? :D

:up:

is it safe for 24/7 use to have NB Volt to 1.53? what is the safest setting for NB Volt?

thank you!!!

this cpu looks so tempting, think im gonna get one any day hehe!
bought a 8400 yesterday, see if it were better than my 8500, the bastard didnt even get into win at 1.25v 4ghz.. required atleast 1.28 to load win...and it was almost 10c hotter at same speed..
more than 1.45+ for 4,3 it sucked bad time! was a q819**** , now its on swedish ebay the same day hehe ... cant have that shaajt, 8600 here i come! :D

how did CR1 suddenly work now, any setting you missed?

and another thing, i tried to set lower vcore than 1.25 but lowest on this board are 1.25? howcome, really annoying!
is it like that for you people?

Sorry I didn't take note of all the settings i used. but I wasn't aimng for stability, just a max benchable fsb without suicide voltages.

off the top of my head it was around 1.57nb, 1.3vfsb, 1.58pll, ram 1:2 around 950mhz 8-8-8-24-2t. PL9, skews all auto

I see you have 4x1gb ram. Getting a high fsb will be harder with all 4 running. You may need to play with the skews.

if you're having trouble with stability, start small and work up from there, 470fsb is not a setting i would use 24/7.. lowering that with tighter timings and PL will end up faster. try 400x9 and if you get that stable, save the bios profile and work it up from there. I'll try 445x9 and post the setting i use if it ends up stable

I don't know if this will help you out, but here is my last stable settings.

9x451, PCIe - 105, 8,8,8,16 timings, Static read & write -disabled, AI twister - Light, AI Booster - Auto, CPUV - 1.44375, DramV - 1.9, NBV - 1.49, CPU & PCI spread - Disabled.

Everything else is in it's default position.

Just finished my updates - case, water etc & will commense pushing even further soon. Will post results as stability arises.

THANX Puttz !!!!! Will try your settings and give feedback.. If u push further with success plz post.. :)

THANX Booj !!!! I'll hold u to your promise for your notes on something stable... :)

Dividers available are linked to strap (200/266/333/400). You can change between the available dividers (and hence end-result speeds) by raising/lowering the value in the RAM speed field, there's no "select divider" option.

Hello .

I have got this board since 1 month , with a watercooled QX9650 and 2*2 GB ocz 1600 .

I use the bios 151 which is , for me , the most stable .

But , i always have some random freeze problem .:mad:

In fact , last night , i did a stability test with CPUstress and my PC has frozen after 4 hours of test !!! :eek:

Temperature NB : 49 °C after 4 hours.

In the bios , I tried everthing is possible to avoid such freeze problem but it seems that it is impossible to solve .

So i was asking me if there wasn't a NB temperature probleme . I think that the original heatsink is not sufficient to cooling the X48 ,moreover that the ASUS blue plate must not help my additionnal 92mm fan to efficiently cooling the heatsink.

Did someone find a solution to improve the cooling on this board ?
Is it usefull to remove the heatsink to see if there isn't a problem of contact or change the thermalpaste and remove the ASUS blue plate ?

Hello . Thanks for the help but my stability test was already dony with no LLC .

Otherwise , i have removed the asus blue plate covering the NB ( which is a incredible stupidity of asus :mad: ) and the result is a far better cooling . But be careful if you want do the same thing because the plate is glued to the NB so it is difficult to remove !

Since the modification , no freeze at all if i select the right NB voltage of course . I precise that before this modification , even increasing the NB voltage , i always have got some random freeze .

And how did you manage to remove it, if glued ?? :confused:

With a screwdriver, a cutter and a lot of patience but be careful , i don't want to be responsable if you do a mistake .:D

In my case , i had no choice because it was impossible for me to have a stable system without this modification .

I just stuck mine in the deep freeze for an hour & the thing practally fell off in my hands. No twisting, prying or anything. Just a tap of the fingers & off she came.

think he may be talking about the strip of metal over the heatsink with the asus logo

That just seems silly to me. I would not be suprised if your freezing problems come back. I agree that it is a stupid place to put a decorative cover, but mine is still on and my room gets up to 85F here in the summer And MY COMPUTER IS MOUNTED INSIDE A DESK!

I would doubt that the removal of that little scrap of metal dropped your temps even 1c on average. I do hope the problem is gone though. I feel your pain as I had problems like that for over a month, that I traced back to my 1600mhz ram. the 1800mhz ram that I have now, requires 1.65v to the NB to run 1N command rate, but I have no issues with crashing or freezing.


Oh, and I have 2 120mm fans pulling fresh air into my desk though. My temps are 2-3c cooler when the computer is sitting outside on the floor.

Hello,

I am another one having the random freezes, even with the cpu not in load.
Runing a E8400 500x8, ddr3 at 1600 1N. I am currently running the vNB at 1.59v the temps are good (39º load).
LLC is off, and i still have no conclusion for what is causing this .. i will try to raise the vnb a bit more.

You should have enough NB Voltage there. What is your Vcore set to? Perhapse you need just a bit more. Also, try 2N maybe those modules don't want to run 1N

My vcore is 1.37v full load. Maybe it's the cpu that is not that good.
I tried memtest and they ran 1h loops, so i think it's no from there, but i will try reducing to 2N to see if it goes away.

Thx soapman

What kind of memory do you have? Besides the 1N issue, are you running at the rated timings? Did you manually set the ram voltage to the rated voltage? Seems obvious, but it is easy to forget to check these after starting from scratch.

still no clockgen for this board :(

Yes , of course , i am not absolutely sure what the problem is gone away forever and in fact , perhaps my ram is not completely compatible with this mobo but for the moment , there is no freeze at all.

I will see in the future if i change the ram but i will wait that prices drop ! :eek:

PS : Could you tell me which ram you have ?

Sure, I have OCZ 1800mhz Reaper 2x2gb memory. the model number is:OCZ3RPR18004GK

I didn't mean to come adross as rude, with my comments yesterday, but I think your thoughts about the ram are far more likely. I had some OCZ platinum 1600mhz 2x2gb memory with timings rated for 7-6-6-24, and although the first kit I received would rin mostly stable after ALOT of tweaking and cranking up the Vdimm, that stability went away after about a 2 week period. I RMA'd the memory, and could not get that kit to work, no matter what. That med me to RMA the mobo, but when the new one came, I had exactly the same problem. Now onto RMA#2 for the ram. New ram, same problem. I got rid of that memory, and tried the 1800mhz Reapers. After finding the necessary NB and CPU voltages, they just WORK. No stabiltiy problems whatsoever, but they will not run any timings tighter than their rated 8-8-8-27.

On the bright side, they do run at 1N which the 1600mhz memory would not. Getting them to run at 1N just takes a smidge more Vnb, and all is stable. I don't remember if you are on Bios 0505 or not, but I would recommend it, as it seems way more stable than the 0204 and 0402 that I tried before.

Oh, and by the way. This board does not report NB temp. at all, the board temp that you see in ASUS probe or Everest is just some generic tepm sensor somewhere on the board, but it is not the same as the NB temp sensor on a Maximus Extreme for example. Too bad for us!

It is a great shame that there is no NB temp sensor on this board, considering NB voltage plays a large factor in OCing.

Don't know if this helps anyone, but I found out thru ASUS forums that the MOBO sensor on this board is located in the upper left corner by the VRegs.

I just needed to know....lol

Guys quick Q for you

my current cpu config is 8 x 333 which = 2.66 ... im a little confused about the memory devider on this mobo, Im sure devider 1:1 is strap 333 .. is that correct? sorry for the noobie Q's :P

This is funny!!!! I know you had trouble with your OCZ 1600Mhz memory since I'm also one of those poor little bastards that is trying to get his memory stable for about 2 weeks now day after day. I read your thread on the OCZ forum since you had some similar problem as I have. You can read my thread here which is an awful lot of reading.

I don't know but it seems this board is really picky with 1600Mhz memory and especially with OCZ's. I think I will bring my current kit back to the store and get me some 2Gb 1800Mhz Corsair memory instead. It will cost me twice as much in the hope it will run twice as good.

Even when you look at the QVL from this board there are not many modules to choose from. It's a shame Asus doens't test anymore modules or doesn't update this list more frequently.

Agree that the QVL list stinks (actually pretty much worthless imo), especially at the level we all seem to be running. OCZ Reapers and Cellshock seem to be playing nice with this board. Not too sure about Corsair. Hopefully the investment will be worth it.

Yeah,

MASSIVE problems. Not to bash OCZ though, because these REAPERS are good. Can't tighten the timings, but they will run faster than 1800mhz. They are totally stable at reatd timings, and if I get better cooling (for my CPU) I will try faster speeds, and check for stability.

FYI....... They do run at 1N which makes up for the 8-8-8 timings.

Can't complain!

I hope so as well since those modules will become the most expensive components of my comp. At least they these modules are on the Corsair website listed as compatible with P5E3-Premium.

I hope I will get my new RAM this week and that they are at least stable at the rated timings as well. And hope that it's not my mobo which is defect but I guess I would have noticed this when the RAM was running at default speeds of 1333Mhz. Still I don't get it because some people seem to get good clocks as would be expected from these modules like here and here. Maybe the P5E3 undervolts the RAM but I didn't dare to push it over 1.94V due to warranty issues.

What cooling do you use now? I will try to overclock my memory as well when its stable. However my E8400 seems to originate from a bad batch and is holding me back from a good OC because I need 1.42V in Bios and 1.4V in CPU-z (with LLC enabled) to get it run at 3.96Ghz. Does any of you have some advise maybe for OC'ing this baby? If relevant I could post the rest of my settings?

Hello .

I have done again memtest 2.01 bench with my OCZ 2*2GB 1600mhz and now i have a lot of errors. :(

2 weeks ago , there was none !

So i must change them .

So, can someone tell me which kit of 2*2GB with speed of 1600 mhz or faster , is fully compatible ( approved by asus ) with this motherboard ?

In fact , if i read the QVL list , there is no 2GB module !!

Thanks.

I had the same problem as you. Modules OK for a week or two. Then problems, freezes and of course Memetest errors when there were originally none.

I have 1800mhz reapers. They work fine in my board with no fiddling. Be prepared to run some high NB voltages to get 4gb to run at 1800mhz though.

Ok ,thanks . I have done a RMA for my kit and asked to OCZ to change it against the same as you and a little money .

I wait their answer to know if they accept the deal .:D

But i am suprised not to find compatible 2GB high speed module in the QVL list .
