So I was playing around with my PC (2.66GHz P4 on a Intel D865Perl MoBo) and I was attempting to overclock it. All was well and good. I accidently changed a setting to the wrong thing and upon restart nothing. Well, to fix this, I did a CMOS reset (changed jumper on mobo and took out battery). PC rebooted with no problems. Prior to all this, the BIOS settings were completely default, so default should be fine. When everything loaded, the System Config showed 1.06GHz. I reboot, same thing. I rebooted into BIOS this time to see what it showed...same 1.06GHz. I have reinstalled the BIOS (same version, which is the latest) and it still reads 1.06GHz.

What to do next? I need my 1.6GHz back!!

I have the computer in the BIOS settings right now, so changes can be easily made!

im not familliar with your bios but it sounds like your FSB setting is low. Probably set at 400 instead of 533 or something like that.

The BIOS is showing the correct speeds for the FSB and the memory. 533 MHz FSB and 333 MHz memory speed.

just FYI...there is a jumper near the CMOS battery that you can move over one pin to get a new menu to pop up in the BIOS. This menu contains the frequency multiplier! It got reset along with everything else. Bumped that up until the processor read my 2.66 GHz again!

it's very odd that you have a cpu that supports different multipliers out of the box..

8/16/2007 11:12:21 AM

^ Most CPUs will run at a lower multiplier, just not a higher one. It sounds like, for whatever reason, his BIOS didn't reset with the correct multiplier. That's the odd thing.

8/16/2007 11:15:37 AM

Yeah don't all cpus support changing the multiplier out of the box? Atleast my last pentium D, and Core 2 Duo did.

8/16/2007 11:22:18 AM

^ Down, yes. Up, no.

I've got a similar problem with a thinkpad at work. 3.06 that runs at 2.63 no matter what the power settings, etc. are.

8/16/2007 12:43:59 PM

^ Speedstep problem?

8/16/2007 12:47:34 PM

^Yeah sorry, up not down, unless you have a extreme edition with an unlocked multiplier. Yeah that sounds like a speedstep problem. Try turning it off in the bios.

8/16/2007 12:51:09 PM

correct, the multiplier goes down but not up, the only processors that do are the unlocked extreme intel's and FX amd's

yea, you'll need to turn speedstepping off

brainfart, was thinking speedstep was fsb for some reason
