Is it unheard of to have a system that will pass over 24hrs small fft as well as blend and yet be unstable? I did my first testing at 1.59v set volts (roughly 1.52-54 load volts). Then I tried to scale down and found that at 1.40-42v, it would eventually lock up or bsod. But at 1.44-46v, it'll be stable again for 24+ hours. However, I've noticed that in the past day, firefox has crashed more than usual. Aim also crashed once, which isn't all too unusual but still isn't a common occurence.

Logged faults:

Faulting application firefox.exe, version 1.8.20061.20418, faulting module NPSWF32.dll, version 9.0.28.0, fault address 0x0004e8c1.

Faulting application firefox.exe, version 1.8.20061.20418, faulting module unknown, version 0.0.0.0, fault address 0x0433493a.

Faulting application aim.exe, version 5.9.6089.0, faulting module ate32.dll, version 2.5.18.0, fault address 0x0001ade1.


Coincidence or still unstable, do you think? No I don't do orthos testing at max priority, and I figure that could potentially have to do with it, but I've never seen this before. Temps are well in check now with lower voltages.
 
Well... the DLL that was mentionned in the OP is a shockwave DLL (I think) or a Flash DLL...

What are your RAM timings/speed?
 
I've tested my ram before at 500 4-4-4-12 and 400 3-3-3-8 without issue in a different board. However, on this board, the best I can do is 450 5-5-5-15. I'm imagining it has to do with either d9 issues with this board and or the fact that this board has a c1 revision of p965 chip and the other one had c2.
 
since you already did 24 hrs of CPU stress and it passed. therefore, the only thing that i can suspect to be unstable is the ram. so try to run blend test?

I did blend for 25 hours the other day but with a higher vcore. I only did small fft testing since the only thing I changed was vcore so figured no need to do blend.

try to blend test each stick of ram at a time?
 
Give it a go with a large fft test as well. That will stress the fsb and the north bridge as well as the cpu in general. If it fails on large fft's it can be either nb/fsb, ram, or cpu. Where as a small fft fail is always pretty much a cpu issue. If you're sure your ram is stable (ie overnight memtest86) then it could be the north bridge needing a little bump in voltage due to the high fsb frequency.
 
I think if you are going to use the system for gaming you should play those games for a few hours. I think Orthos is just a way to heat up your system CPU temps and run it at 100% for a long time. It does not do much compared to what a game will do to test the stability of your system. All orthos basically does is test your FPU.
 
Hmm, I'm having a little bit of abnormality currently. I've previously tested stability with both blend and small fft's. Both passed 24+ hours stably.

Last night, I went to try a 3dmark05 benchmark and it bsod'ed the first time. It went through the second time, but it made me question stability. So then I tried large fft and blend again. Both now cause lockup or bsod. Alright... small fft again. Passes over 8 hours no problem. So I suspect memory (which I'm already running at loose timings even though they can do tighter due to my current motherboard). I run memtest for 5 hours with no problems. Then I did test5 loop for 2 hours. Neither ever errored. I haven't run for longer yet, but I can't imagine it not being ok (I was able to run at higher frequencies and tighter timings on a different motherboard and went through 24+ memtest with no errors.)

So what was once stable just a few days ago is now not. I've had problems with this motherboard since the day I got it, with occasional periods of incredible instability. During these times, even running at stock speeds will lead to lockups. But then after a while, it smooths itself out (if it doesn't, I leave the machine off for an hour and it behaves well).

I tested the psu a month ago when I originally suspected it, but it was fine.

I'm thinking of doing vdroop, vdimm, and vmch mods, but I'm afraid they might be bandaid solutions at best, and there's a good chance it won't even help. I don't have another motherboard to compare with anymore, but it looks like this one is no good. I don't understand why sometimes it'd be completely flawless, but at others, it'll keep on crashing, or not even want to post.

I know the feeling... My original Asrock 939 Dual Sata board used to be perfectly stable at 2.75ghz, then one morning it wouldn't post over 2.4ghz.

Upgraded to an Asus board and got stable at 2.66ghz...

ceteris paribus, something happened to one of my parts, overnight...
