i7 2600k 4.4ghz @1.28v

I have had the ram running 1.57v for well over a year though. This only happens when I touch the cpu.
Let me try disable PLL and see if that does anything.

Not changed anything yet and couple power off and on and it's starting up fine. My god this Overclock is fussy, so its a waiting game again to see if it boots fine.

Overclocking the cpu does require more dram voltage though, i found that on the p8p67. Don't forget to disable PLL.

Yeah but even on my z68 board I was running same voltage for the RAM. PLL will be the first thing I will disable if it happens again. Its a tricky thing because it dont always happen.
 
you can try stock 1.05v vccso or vsca and set the other vccsa I think it is from stock .9v to within .5v of the dram voltage,see if that has any affect
 
If you are on about the PC starting to a black screen, then after a few seconds auto rebooting I wouldn't worry about it. It seems to be an ASUS motherboard thing.

I've had that on every ASUS board I've ever OC'd on. My current P67 does the exact same thing. Yet I know my CPU is 100% solid as a rock, it'll run IBT / Prime95 etc all day long.

Thanks for your input, this is what's happening. But why not all the time?

It's something to do with how the ASUS mobo's apply the OC, and sometimes have to do an internal reset before doing a full boot.

But as you say it doesn't happen every time.

I gave up caring about it and chalked it up to a quirk of the ASUS BIOSes.

As long as my PC is solid once it's in Windows that's all I'm bothered about :)

EDIT - Here you go: Info

"Some of you may have been experiencing a double POST on your P8P67 series motherboard whereupon after powering on the system from a cold boot, the board will power on and then immediately reset itself before it actually POSTs and shows any display on the screen. I’ll explain the fix below and give some information about why this happens."

...

"From time to time we needed to implement full resets in order to maintain stability due to the architecture of the Sandy Bridge platform. For instance, the system may require one full reset when the PCH power has been cut during S5 power state. To fix the most common additional reset (double POST when powering on from off state), enter UEFI BIOS -> go to ‘Advanced’ tab -> go down to ‘APM’, press Enter -> enable the “Power on by PCIe.” function. Then press F10 to save & exit. After save & exit, let the system boot into Windows or other OS, then perform a proper shutdown: Start button -> Shut down. You will no longer have the double POST."

I assume the same thing applies to your Z77 board while using a SB CPU.


(Weird thing is, I've had the exact same thing on older boards from the Core2 era that did the exact same thing, so there's probably more than one reason why these double posts occur)

Thanks guess i'll just let it be then :D Once booted I am very stable 4.4ghz @1.29v I happy with that max temp is just 50c
