[SOLVED] ASUS P8P67 B3 Turbo Mode not working

[Vadatajs]

EDIT: It turns out Linux must have been reporting turbo mode wrong before. The latest svn version of i7z shows the correct turbo mode with all cpus active (3500 MHz).

I just rebuilt my system with the replacement P8P67 board, and now turbo mode no longer works.

Prior to the replacement my CPU would run at 3.7 GHz under load, temps were around 50C with my heatsink.

Now the frequency tops out at 3.4 GHz.

Details:

Board: P8P67 (not pro)
CPU: i7-2600 (not K)
BIOS: 1305

I have speedstep and turbo mode enabled in the bios. Just about everything else is set to auto. In version 1003, this was enough to enable turbo. I can't downgrade because the updater won't let me.

Any ideas?

enable C1E.

enable C1E.

C1E was set to auto. I enabled it and it's still pinned at 3.4 under load. Do I need to enable the C3 and C6 too?

I even tried manually setting the target ratios in EFI. It still doesn't report anything higher than 3401000 to the OS.

You can't downgrade to an earlier UEFI bacause the earlier BIOS does not have the code to run the new B3 stepping PCH.

Are you sure ?

The BIOS they are shipping now , 1305, was issued before the recall ..

That's my understanding after doing a little more research.

Major detail I left out: OS is Fedora 14.

I think this might be my answer: https://bbs.archlinux.org/viewtopic.php?pid=899261

According to that thread, when it shows 3401 it is in turbo mode. This is different than before. I don't believe it's not possible to see the actual frequrency in turbo mode, that's what I saw before.

According to Asus.

You will not be able to roll back to an older UEFI after this update as it contains new firmware and B3 stepping compatibility.
