My two months old system is overheating and shutting down by itself. I have an Intel Quad-Core QX6700, PSU Tagan 1100 and ASUS P5N32-E SLI QUAD 680I 775 MOBO. The case is a Coolermaster Stacker 830, plus a liquid cooling from Coolermaster.
I am getting the following report from PC Probe:
CPU Temperature Abnormal, 66 degrees centigrade
1.2VHT Voltage Abnormal, 1.50 V
SB CORE Voltage Abnormal, 1.71 V
DDR2 TERM Voltage Abnormal, 1.01 V

I went to the Extreme Tweaker option in BIOS, Over Voltage Menu and changed the 1.2 VHT manually to 1.2V and the SB Core to 1.5. Now PC Probe doesn't give me alerts for these two. However, there is no option to manually change the DDR2 Term Voltage (I still get an alert for this one) and the PC is still overheating. What is odd is that the computer overheats when I have only the Internet Explorer running, I mean, I am not demanding any extra power from the system or anything.
Does anybody know where in BIOS can I change the DDR2 Term voltage?
Is there any part that could be defective (PSU, MOBO, CPU etc..)?

Hmm, so it looks like you're not even overclocking that thing? Get coretemp and report back with what your actual coretemps are.


as far as ddr2 term voltage, what is your vdimm running at? A lot of the times, if there's no setting for termination voltage, it's calculated by vdimm/2. I wouldn't worry about that at all, and if possible to suppress that,
