Odd OC problem -- Not for noobs

Same way, adjust the multi and QPI. QPI is like the FSB on LGA1366

Except for the CPU/MB, HDD is the only part that you haven't checked. Hence, firstly I would check if it is the reason of unexpected locked-up by swapping them with the ones from the rest of WORKING PCs of yours, although it is unlikely to be the reason. If it doesn't work, I would then take out the CPU and check if there's any sign of burnout of CPU/socket, unreasonable scratch of CPU connectors or bent pins on the MB.

If everything seems to be fine, then there is a great chance that the MB is the reason causing problem. What I would do is getting a new MB of the SAME model as yours from the SAME seller first and then see whether it fixes the issue or not. If the problem is gone thereafter, return the old MB to the seller and ask for refund of the new one. Congratulations, it's time to ask Intel for a free brand new CPU if the issue still appears.

Andy, see my posts 2 up from yours. I think I fixed it. Memory will not run at rated speed, but now I am working @ 3.6, and it appears stable.

Oh, OK....

I was too lazy to go through all the replies.

By the way, time to edit your sig.

So you are sure its the Memory?

So you are sure its the Memory?

Well, my old OC died completely, and I started with a bunch of different settings, so it could be a combination. I think I have learned that VTT and PLL don't need to go up, unless you want over 4 ghz (my guess) and I do know at the 3.6 first try, it was giving problems at 1440 ddr, but at 1080 ddr, its fine (the memory is 1600). So I do know the memory won't run rated speeds, or the motherboard doesn't like that speed. I may leave it at 3.6, or even try for 3.8, but I am happy with either.

Just very interesting all the things that have happened, that never hit me in the 775 world.

And what speed in your Asrock 920 doing ????

I miss the 775 world. I do have a UD3R P45 and an extra Q9550 that will do 4Ghz /500fsb x 8 at 1.375v bios and 1.34v in OS - I think I may buy a 1066 kit and do some OCing just for kicks.

Maybe the memory voltage regulator is bad and caused a spike that put your kit over its maximum allowance before failure?

did you try flashing your bios to v1.20? After I flashed the board it allowed me to run my ocz @ 1600 stable.

it was giving problems at 1440 ddr, but at 1080 ddr, its fine

Have you tried an OC with the ram very low to eliminate that as a problem?
