New 2500K Build, Stuck at 16x

post #1 of 26
Thread Starter 
Wow, I feel like such an idiot here. New Sandy Bridge build on an Asus Sabertooth P67.

Running the latest "BIOS" (1305) and my system is permanently stuck at 16x.
Load up the CPU to 100% in Prime95 and it sticks to 1600MHz.

Any ideas? Can't see what's set wrong here.

Are your power settings stuck to Power Saver?

Try turning on speed step and the other power saving features to see if that does anything.

Nope, was a fresh install of Windows 7 SP1, was on Balanced, setting it to High Performance makes no difference.

In the AI Tweaker menu, Click the CPU Power Management..
Set the MULTI there, and disable Speedstep ..
Great success

Still 16x…

It was running 1305 from the factory, I'm going to try flashing it myself and see if it makes a difference. (seems unlikely)

Dont flash it yet. The factory bios is the latest one anyways.
Try a CMOS reset. Then retry overclocking it. Just setting the multi as I stated above..
Adjust the vcore as needed, Turn ALL power savings features off.

Still stuck at 16x
I'm only trying to hit 34x as well (setting 33x manually doesn't seem to have any effect)

I know there must be something wrong, but I can't see what. Is there some kind of driver I could have overlooked with my Windows install? I just downloaded and installed everything available on the ASUS site.

When you reset the cmos, Did you do it with the jumper with the PSU off?

I tried the OC tuner setting and it jacked my bios settings all up, Took resetting my cmos with the jumper to fix it.

I didn't actually clear the CMOS, I restored defaults. It may well be the OC tuner that has messed it up as I tried it by mistake when I first had the board up and running—didn't realise it was automated overclocking.

It'll have to wait until morning to clear the CMOS properly now, ripping the top off the case (FT02) at this hour is probably going to wake everyone up.

Unless it's possible to clear the CMOS via software like the good old days where it could be done via DOS?

Thanks for your help so far, hopefully that will sort it…
