Help me with stability/heat issues.

post #1 of 8
Thread Starter 
A lot of you know I am building an overkill folding rig

P6N Diamond
QX6850
8GB of memory
4x9600GSO

I got the system up and running a couple days ago with one of the cards and ran a prime95 small fft test and 2 things happened.

1) Temps went to 75*C
2) the test failed within 10 seconds

I have a pretty good idea about what I need to do to remedy the heat issues, but what about stability? I have not done anything except adjust NB voltage to stabilize the system with all 8gb of RAM. I am going to try reapplication of the TIM and try some different TIM today and see how it goes.

prime95 will error when you get that hot, even if you have plenty of voltages going through the board. Have you even tried to OC yet? I would do what you are doing and make sure that v8 is on good and tight, then try running it again.

Just curious, but what do you need 8 gigs of ram in a folding rig for?

Wouldn't 2 suffice?

Probably. But then it wouldn't be Superfold. It would just be another folding rig.

Was not aware of Prime95 failing if it gets that hot. What about Orthos?

And no, that's with no OC whatsoever. Only the aforementioned NB adjustment

You need to readjust the heatsink. Any stress test is likely to fail at those temperatures, because the warmer it gets the more likely the CPU is to make errors. That is part of the reason watercooling is so effective, keeps the CPU cool which in turn allow for greater stability even at the same voltages.

Because 8 GB of RAM places incredible strain on the memory controller in the NB, it's gonna throw lots of weird errors at you, including the Prime95 stops.

Turn the Northbridge voltage up 1 or 2 settings and try again.

But unless you used too much TIM or the heatsink was seated incorrectly, a Coolermaster V8 shouldn't generate that much heat, even if the processor is a QX.

Failing at stock speeds usually means you have RAM issues. USUALLY.
Try doing only 4 GB of RAM. If they don't work try the other 2. If both don't work post back. You have your RAM voltage set manually right? DDR2 defaults to 1.8 If your RAM needs more then that could cause instability.

right. RAM is set manually to 1.9
