Where is IOH voltage on my board?? - Page 4

post #31 of 35
Probably nothing wrong with the board either. Prime95 and IBT do not test the PCI-E controller. If the problem does lie there, increasing CPU voltage (try IMC, vcore, and PLL, in that order) may help. IMC should control the whole uncore, including the PCI-E controller.

What sort of OC settings are you using?

Something interesting I found that leads me to think my ram is defective.

I tried running OCCT GPU stress test with the above overclock settings and SLI enabled. I could not pass 240 seconds of the test without restarting and getting the bccode 116 error. I tried the test 4 times with these settings.

I tried lowering the dram frequency from 1600Mhz (2:8) to 1200Mhz (2:6). This time the test went up to 1300 seconds before a hard lockup.

Does this mean that my ram is defective since the XMP settings are 1600Mhz 8-8-8-24 2T @ 1.60v??

I'm only able to pass OCCT GPU when i reset my bios to default settings. Does this indicate a problem with my PSU or CPU?

Alright! Finally, I think I've solved the problem. I lowered my bclk from 200 to 173 and both GPU's in SLI passed OCCT GPU without crashing the pc.

This leads me to other question, is my CPU faulty? I've had it over 2 1/2 years and this is the 3rd computer it's been in. I can't really understand why I'd have to lower my bclk so much to get my SLI to work.
