Getting BSODs is it RAM or CPU?

post #1 of 5
Thread Starter 
I cranked up the BCLK from 180 to 181 and pushed the voltage from 1.25 to 1.26. My dram voltage is at 1.6 and I set the QPI to 1.35 on 12 gigs of overclocked ram to 1800. Everything was stable until I changed the BCLK to 181 and voltage to 1.26 and changed the QPI to 1.35. So is it a ram or CPU issue?

It's rare that you have to overvolt your ram away from stock voltages unless your going extreme like 4.5+. I'm at 4.2 with my 950 on stock ram voltages. It's more likely the CPU voltage. Up the CPU and QPI and see if it works. Then go back in and fine tune your voltages. for reference my CPU is at 1.28v @ 4.2. I hear qpi should be set slightly higher than cpu.

You probably have D0 stepping I got C0

First of all, it's always more of a challenge to overclock the CPU when using 12GB ram, especially when also overclocking the ram.

Personally, I always achieve a stable CPU overclock first, with the RAM at stock settings. Then I proceed to overclock the RAM.

What you need to do is pay attention to the BSOD error code that starts with "0x". That will help you determine what voltage needs to be tweaked. Read the following guide; and you'll see a list of the most common BSOD error codes, along with the adjustment you should make.
