As Murlocke said the 1344 and 1792 custom fft's are great at finding instability on SB for initial stress testing. It's also a good idea to go for 18+hrs instead of 12 of custom blend test. Only doing 12 hrs will not test it with all of the fft's. And yes 101 is vcore (more then likely) so I would start there.

Also if you ever miss a bsod code here's a program that will show the codes for you;

Yeah I did have C3 & C6 on auto all along but switched them to disabled just the other day because I thought they might be the issue. Also I'm pretty sure his overclocking guide says to switch them to disabled if you use offset voltage right!?

I think I may go for a longer blend test next time yeh. I passed the 1344's and 1792's before the 12 hour blend test. The problem was that I was doing a standard blend test which has a low RAM usage and also wasn't changing the RAM usage with the custom FFT's. I wont make that mistake anymore though!

The Sandy Stable club front page says that 101 is Vcore so it's likely. I'm just having a little mess around with VCCIO, PLL and Spread Spectrum first to see if it can last any longer. Then I'll go for Vcore.

I am using Blue Screen View already btw. Thanks for the tip thumb.gif

Just wondering with PLL voltage. What affect will having PLL Overvoltage enabled do in the BIOS if I set PLL voltage manually? Especially if I set it below standard PLL voltage? Don't know if I should disable that setting or not...

I don't tink anyone has ever explained the differences between the two.

But "PLL Overvoltage" is needed only once you've hit a high enough multiplier that Windows begins to crash at startup.

I think it's the Gigabyte mobos that need c3 and c6 disabled. I'm running an Asus p67 pro with them on auto and never had any problems. Not sure about the PLL overvoltage and the CPU PLL but I usually see that Internal PLL overvoltage should only be needed if you fail to boot in to windows at higher clock speeds.

Well if that's right then I guess I should disable Overvoltage. It seems that lowering PLL voltage makes things more stable, especially with the really high overclocks around 5Ghz. So I'm wondering, who the hell is actually going above 1.8v with PLL!?

Also I am running these custom FFT's with RAM at 7000MB out of the 8GB that I have. When I go for the final custom blend test - what amount of RAM should I set P95 to use? I'm sure some people will say 100% but isn't that to much considering the operating system is going to need some dedicated to be able to run?
