Before anything else, here are the computer specs:
Core2Duo E6850 3.0Ghz
EVGA Nforce 680i SLI
OCZ 2GB DDR2 PC2-8500 SLI XTC
Seasonic S12-500W
2 x GEFORCE 7800GTX (SLI)
4 HDs (1 - 10000rpm and 3 - 7200 rpm)
1 DVD-RW
1 Creative X-FI
6 120mm fans (NZXT tower case)
I am having problems in my computer that was upgraded a couple of days ago with a new CPU, mobo and memory, and I haven't even started messing with overclocks - instability is always with stock clocks.
The instability happens whenever I run any CPU stability test like Prime95, Orthos or Everest (both Vista and XP give the same errors with fresh installs on both of them). After a couple of seconds of any of the tests (usually doesn't even make it to 1 minute) it gives a hardware error and stops the test. At first I thought that it might be a memory problem, so I tested with Memtest and it passed with no errors. Secondly I thought that it might be a power supply not giving enough "juice" to all the hardware, so I stripped the system to only one graphic card, 2 hard drives (with Vista and XP) and one memory DIMM, but still the errors occurred.
The registered voltages on idle/load in the full system and the stripped down are:
+3,3v - 3,18v
+5v - 4,92v
+12v - 11,93v
They are all below their normal values. Might the problem be here?
All the temp reading are within the normal parameters:
CPU - 35º
Northbridge - 45º
Lastly, just for curiosity I tested every stability test with one of the CPU cores and with both... and here is what happened:
- with only core#0 all the tests pass with flying colors;
- with only core#1 all the tests fail;
- with both cores all the tests fail;
Since I can now replicate the error every time, it is just a matter of finding which component is failing, which is why I am posting this - to get your expertise on this issues.
I don't have any spare parts that could help me separating the problem, so from the facts stated above, which component might be the culprit: CPU, mobo or power supply?
