Suddenly can't overclock and only half RAM available, help!

[HungryPillow]

Hey guys, I don't know what happened but today I noticed that Windows said I only have 8GB of RAM available (should be 16GB). So I checked CPU-Z and it says 16GB, and then I checked my BIOS which says 8GB. So then I tested each stick one by one and they boot up fine and memtest86 shows no errors.

Then I noticed my CPU overclock in my BIOS was gone. I've been running my 3570K at 4.3 GHz for the past few years, but now the CPU ratio is stuck at 34. I can't raise it past 34 no matter what I do (it used to be 43 no problem). So I tried flashing the latest BIOS, I tried resetting CMOS, none of it worked.

I have no idea what to do now. Is my motherboard dying/dead? I guess it's not a huge deal since everything seems to still work fine, just that I'm missing half my RAM and I can't overclock anymore lol

I uploaded some pictures of my BIOS below:

at own risk, but i noticed the download link for the tool no longer works...

You can load optimized defaults? if cannot reflash bios? if cannot then really gone case

Resit your CPU

Tried this and didn't work

Thank you for this, I tried almost all the methods in the links and finally found one that worked. I followed the last 2 posts in this link: http://www.tomshardware.com/forum/322017-30-turbo-multiplier-missing-asus-motherboard and it fixed my issue... so weird that my BIOS would randomly corrupt...

Means never flash properly on your first try.
Strangely though, a corrupted BIOS will at least fail checksum first.

At least yours still boots. I've had mine that became unbootable when hot and only bootable when cold. Reprogrammed the BIOS, fixed it.

The flash memory they use for BIOS nowadays really CMI.

Yea... so weird... I flashed my BIOS literally 4 times though lol. I did it through Asus EZ Flash in the BIOS before though so maybe using that AMI flasher is the better way.

apparantly abt this issue the corruption seem to occur not during initial bios flash, but during pc use eg failed oc etc.
and the normal asus bios flash tools fail to recover properly after the corruption has occurred...
