not in my situation. i cant get the bios to post so its irrelevant apart from the ram and thats fine... but i did install the OS fresh after my upgrade of course. haven't error checked my hdd but the bios wont post so dont see how it matters until im past that stage...

I would like to help determine whether or not it is the board or the CPU. So please when you get the time, post your screenshots and also answers to the questions above.
Thanks.

i have used many different bios's and settings... im perfectly stable at 4.1Ghz, can get 4.2Ghz to post but crashes in operating system very quickly, seems to take quite a big bump in vcore to get 4.2Ghz to post to.

will post some screens of my current bios settings later - gotta wait a couple hours waiting for a hdd job to finish...

thanks for your efforts...

Thanks.

By the way how did you determine stability at your 4.1ghz overclock?

ive editied that post since you quoted it....

40 runs on intel burn test, same on LinX, 12 hours prime95 blend, left computer idle for 12 hours and gamed on it for about 12 hours (not in one run). thats more than good enough in my books smile.gif

Your memory setting should be on 2T, that's what's causing stability issues.

its always been on 2T when overclocking. the XMP sets it to 1T though.

OK munaim1 here are the screens of my current BIOS settings (keep in mind i change these when trying to overclock (power limits, voltages, C states etc...):

When OCing in offset mode C3 and C6 should be disabled. Additionally, I would up your short and long duration power limits to 250. Internal PLL overvoltage should not be needed at such a low multiplier.

Also what is your chip's VID?

I personally have found it much easier to start using fixed voltage, and then switching to offset once I've found the sweet spot for the multiplier.

already done all that...

i used realtemp to check the VID but it changes so im not sure. it runs at around 1.3-1.32v if i set the voltage to auto.
