I'm having some issues. I've had my computer built and running for a little over a week now. I have a Q6600 in it overclocked at 3.2 GHZ. I'm having issues with the 4th core. I run Prime95 and the first three cores have had no errors (running for hours several times), but the 4th core comes up with an error in a matter of minutes!
Here are my specs:
Gigabyte X48 DS4 Motherboard, All of the energy saving and cpu throttling functions turned off
Q6600 G0 @ 3.2 (4 x 800)
OCZ Reaper Ram running at 1:1 800MHZ 4-4-4-15 Latency
Xigmatek HDT-S1283 Heatsink with extra bracket and Arctic Cooling MX2 Applied
I have my vcore manually set at 1.35 in the MB but CPU-Z detects it at 1.328
My cores all run about 35-40C at idle, top off around 65C on load (According to Speedfan)
I first ran into this error a few days ago and after I couldn't figure it out, dismissed it, but now I'm noticing major performance issues in Crysis, so something must be bottlenecking my 4870's in crossfire, so I'm coming back to this.
Tell me any other info you need and I'll provide it. Thanks for the help!
try setting ur vcore to auto, gigabyte boards r designed to auto supply more juice if necessary for a component to stay stable (to a degree.. it wont kill ur cpu). If that doesn't work, try running memtest86 first, prime can fail from bad ram.
....also trying increasing RAM voltage, I had a similar problem with my Q6600, trying to get it to 3.6GHz. Also, your CPU just may not like running at 3.2GHz, as all CPUs are different.
But try CPU and RAM voltage increases and see how you go
its not normal, I had the exact same issue with my Q6600. In order to run mine @ 3.4Ghz (stable) I had to increase voltage to my RAM, even though I never over-clocked the RAM. I didn't touch the voltage on my CPU as my motherboard (Asus P5E) seemed to handle it. Give it a go, just do very small voltage increases, as to not kill your hardware.
What do your temperatures look like? If you're having performance issues in Crysis (rather than outright crashes), it sounds more like the CPU might be throttling itself to stay alive. This happens when the temperature gets quite high... so Run Prime95 for 20 mins and read the temps with CoreTemp.
