I was planning on OCing my Q6600 system this week (put it together before X-mas and haven't had the chance to mess around yet).
I downloaded SpeedFan and noticed that the temps displayed for each of the cores at idle are 19, 17, 11, and 11. The 6-8 degree difference between cores 2/3 and 0/1...
I'm helping a friend put together a new system (over the phone) and I've run into a problem. He's got an Abit NF7-S (rev 2) and an Athlon XP Mobile 2500+. When I was walking him through the Soft Menu setup I had him set the FSB to 200 and the multiplier to 9 so that it would be at its default...
Has ASUS released a Bios that corrects the CPU voltage stability problems?
I've been away from the forum for a couple of months (busy at work and home) and so I haven't followed this thread for a while.
I was running my 2.6C @ 3.2 with the stock cooling for a while. It was very stable and the full-load temp peaked at 57C. I put in a Zalman CNSP7000AlCu HSF and the temps dropped 10C and now I'm stability testing at 3.4Ghz. A good HSF buys you more OC room.
Actually, the 2.6C I just purchased was running stable at 3.2Ghz with the standard stock HSF (57C under full load at default 1.525V). I purchased a Zalman CNSP7000AlCu so that I can overclock further though- it drops the full load temp at 3.2Ghz to 46C.
The Prime95 author created an updated executable that fixes the problem. He posted it on our Prime95 forum discussion thread. I'm using it to run a torture test right now.

Yeah, it's at 2-2-2-6 and I set my Vdimm to 2.75V also.
Right now I'm running my FSB at 246 with the memory set to 4/5th timing. I put my Zalman CNPS7000A on and the idle temps dropped 10 degrees. That's just amazing to me. I'm gonna run the stability tests overnight and if I'm stable at...
Some of the blend tests seemed to hit the HDD pretty heavily- I can't remember which ones though.
I decided to go ahead and put my Zalman cooler on now that I'm more certain the CPU/Motherboard are in good shape. I'm going to overclock to 3.2Ghz and run v23.6 blend test tonight.
Someone else on the mersenne.org boards posted with an 865PE board. They too get the crash so it sounds like it may be a software bug.
The bug actually will occur on the blended test too once it hits that combination of FFT and exponent. That's where I first noticed it.

It sounds like NookieN on the mersenne board has the same problem with his Albatron 865PE board and P4. That is even more evidence that it is a possible software bug.
Computer,
What settings and/or configuration do I need to run the WMD test you requested? I ran it with my current setup and it ran through one pass with no problems. Let me know and I'll set it up the way you need me to.
Motojeff,
Make sure you have the USB Legacy option disabled in your...
Me and at least two other people have encountered a problem where Prime95 will crash on exponent M420217 when using a 20K FFT. This is easily reproduceable by choosing the custom option in the torture test and setting the minimum and maximum FFT size to 20K. When the testing hits M420217 then...
Yeah, it's entirely possible that is only a software bug. I wish I could verify it because I am ready to start overclocking and I don't want some nagging doubt about my hardware.
Can someone help me and a few other Asus P4C800E owners with a problem?
If you have 1GB of ram (2x512MB) download the latest version of Prime95 (v23.7) and try the custom torture test. Set the minimum and maximum FFT size to 20K and see if it crashes on exponent M420217. It does this for me...
I just downloaded the previous version or Prime95 (v23.6) and it did not crash. They added new P4 improvements for 23.7 so that doesn't necessarily tell us anything. It's either a bug in v23.7 or a bug in our motherboard as far as I can tell.
I'm gonna post in one of the other forums to see...
Actually, the guy on the Prime board has a 2.8C which will have a different spec code so it's not that.
I too wonder if this board will still work fine or if I should consider getting an Abit IC7 instead.
I'm not using IAA either.
Intel Inf: 5.02.1003
Intel NIC: 7.0.37.0
Default Microsoft Video drivers for the Geforce MX2 that's in there now.
Onboard sound is disabled, and I haven't installed my soundcard yet.
I installed Windows XP, followed by SP1, followed by the Intel INF and NIC drivers...
Yeah, I boosted it to 2.75 and it didn't make a difference. As a matter of fact, no matter what settings I change in the Bios Prime95 will always crash when trying the 20 FFT with that exponent and its default memory size settings (926MB). I even OCed to 3.2GHz and it will run flawlessly till...
Amused,
Prime95 will crash in exactly the same spot every time I run the blend test.
It happens on M420217 with a 20K FFT.
If I try a custom torture test, I can choose 20K as the max and min FFT and it will happen on M420217 every time. It will pass it successfully if I alter the memory...
I'm about to RMA my motherboard.
I ran two instances of Prime95 overnight on the small FFT setting for the torture test and had no crashes or errors at all. The CPU was fully loaded the whole time. But if I run one instance of the blend test Prime will crash within 2-4 hours. I know its not...
I don't think he was referring to stability issues with Athlons, but more with the cheaper VIA chipsets.
VIA chipsets (unless something has changed in the last year) are generally not very stable. This is not a reflection on AMD, but a reflection on VIA so don't get your panties in a wad...
Update:
I received my replacement memory on Monday. I pop it in, run a single instance of prime95, and the program crashes two hours later. I try each memory stick individually and it still crashes. So I'm thinking there's no way both replacement sticks are bad. I decide to burn memtest86...
I'll give it a shot. Of course, the whole reason I bought this ram was for the 2.0- 2-2-3 timings indicated in the Anandtech review. I tried a set of Corsair PC3200 ram at its default settings and got the same Prime95 crash so it's probably not memory related.
I've got a Prime95 problem and I'm wondering if it has something to do with my P4C800E.
This is what I'm working with:
P4 2.6C w/ stock cooling
2x512M Mushkin LII PC3500
36GB WD SATA
ASUS P4C800E w/ latest bios (1014 i think)
Geforce MX2 - temporary card until I'm satisfied the system is stable...
Thanks for the info. As soon as I get the new memory in I'm gonna give it another go.
I would try TMPGen, but I don't have any video capture devices or video to encode.
I've got an SL6WS 2.6GHz with D1 core stepping. I'll let you know how well it does once I've worked out a stability problem that occurs even at defaults. I pulled out one stick of ram and it ran Prime95 for 10 hours without problems, so now I just have to determine if it's the memory I pulled...
I'm having some trouble running Prime95 with a new system:
P4C 2.6GHz (SL6WS) - currently using stock fan/hs
2x512MB Mushkin L2 PC3500
Asus P4C800-E
WD360GD SATA HD
Geforce2 MX - old card I stuck in temporarily
Once I had everything hooked up and all the Windows XP updates installed, I decided...
