You'll want to run intel burn test with thread count set to 8 otherwise it doesn't use your processor to 100 percent. upsidedwnsmiley.gif

Here's my result with an Asus P9X79 WS:

For some odd reason I cannot get the GFflops to stay consistent.

For the life of me I can't get my system to boot, and I'm thinking it's the RAM.

Specs:
3820
Gigabyte Assassin 2
CML8GX3M2A1600C9W (Corsair Vengeance Low Profile 1.35v)
GTX690
AX850

I'm basically trying to get it to boot at 125x36 for a nice 4.5Ghz OC that I can run 24/7. I've gone as high as 1.42 VCore to try and boot.

Vtt - 1.1
PLL - 1.9
IMC - 1.0
C1E, C3/C6, and EIST are all disabled.

For the memory, I've tried going up to 1.5V, loosening the timings, reducing multiplier, and even straight XMP. It will boot no problem going with a standard 100x42, but as soon as I increase that BLCK to 125, all hell breaks loose. Am I right in that this memory just isn't cut out for a solid OC?

Are you sure those sticks are compatible with that board? Go to the support page and look up memory compatibility. I almost bought a set that wasn't on the list. It's also possible you got a terrible memory controller on your CPU and you can't use the 125 strap. I would lower PLL to 1.6v or less too.

It was the Corsair Dominator that I was going to purchase.

For starters, have you updated the BIOS?

Also, try 1.8v PLL (or less) like JKDC mentioned. I've found that Corsair Vengeance are horrible at overclocking, at least the previous pair I had were.

If those two things don't help, try enabling C1E, C3/C6, and EIST. There was an article someone linked earlier mentioning that those should be enabled up to a 5GHz overclock.

First overclock on Sandy Bridge. Everything look ok? I adjusted some of the auto OC settings.

I think it's to do with different monitoring tasks being done while u are testing. I think u should try again in diagnostic mode.........if it doesn't disable too much that is.
