ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

[tiesum]

Hi Guys,

This morning I finally haf the the to build my new P8P67 Pro - 2500K setup. I installed windows and started to OC. i first read some guids as I come from S775. I have a problem though:

I raised the multiplier to 45 to get a 4500Mhz OC. However in windows when stressed (Prime95) the speed only goes up to stock (3.3).

What am I missing here????

(I installed the last CPU-Z 1.56.3 which displays 3.3GHz. I also get this value in the Asus Turbo V software)

Nope...Tried some more but can't seem to solve it...

Need...help...

You have to select "By Per Core (Cannot Adjust in OS)". With 1253, it would reset that back to auto every time you entered the UEFI. I flashed mine to 1204 and I'm not having that issue anymore.

I'm also on 1204. Still the same problem though. When I see the post screen I always see the standard speed of 3.3 GHz. When stressed in windows cpu-z (1.56.3) also shows 3.3 GHz. The Asus turbo-v software shows the correct multiplier I just entered in the Bios though (45x).

Flashed back to 1253. Same problem as on 1204. I'm starting to lose it... Already thinking about RMA but I don't know if the CPU or mobo is the problem..

Finally solved my problem. I was unable to increase the turbo to above 33, no matter which values I entered in the bios. The problem were some ssd register tweaks I did right after the Windows installation. Somehow some register values must influence the turbo mode. A fresh install fixed the problem. Just started overclocking. First results (prime95 stable)
