Overclock in BIOS not sticking in Windows

[azsportsfan]

Hi folks. I have a 3770k and Sabertooth Z77. In the BIOS, I have the OC set at a mult of 44 (100MHz clock) and a voltage of 1.225v. It saves there just fine if I reboot. The problem is, when I boot into Windows, it gets set to a mult of 42. So, in Prime I am running at 4.2GHz instead of the desired (and BIOS setting of) 4.4GHz (CPU-Z). Although, the voltage is set at 1.225v. If I use the ASUS windows OC tool and change it to 44, it sticks through Prime, until I reboot and it once again is back to 42. Any thoughts? What am I missing?

Thanks in advance...

what are using to verify this? My 960t will read 3.3 ghz in WEI, but I have it oc'd to 4.15 ghz...

CPU-Z. When I overclock in windows itself, then CPU-Z will show the 4.4GHz (until I reboot). Once I reboot into Windows (7 x64), it is back to showing 4.2GHz...

Is there a better, more accurate tool? Things like Crystal seem a liitle outdated.

As a follow up, even ASUS' own monitoring tool shows 4.2GHz upon reboot...

Why won't the OC stick in Windows?...

It's post your bios settings time. The Asus MB I used to have had the ability to take screenshots of your settings....Saves to USB stick I think.

Thanks for the welcome.

I have found part of the problem - setting the CPU OC via the windows tool (TurboV EVO) DOES NOT save them to the bios, which is why anything set in windows does not stick (either in BIOS or reboot into windows). Had to read the fine text for that. But still, settings in BIOS do not manifest in Windows. Will post some pics here shortly...

Here are some pics. I have reset the BIOS, saved and then modified to these settings (4.3GHz) and saved again. Booted into windows to find stock settings (3.9GHz turbo) shown in both CPU-Z and ASUS Monitor.

What options do you have for turbo ratio? The last Asus MB I used I think had by all core, per core options but was P67 chipset. I don't really see anything that looks whacky to me. Maybe Asus software causing it? When you look at the OC page what is the multiplier set too?

It is either Auto (base multi) or Manual.

I went ahead and reflashed the BIOS (same version), and now the settings above are sticking in Windows! Finicky piece of ....

Thanks for taking a look. Cheers and Happy Holidays to you.
