"Actualclocking" a Inspiron 5100

Heres the deal, I got an Inspiron 5100 Laptop, which supposedly supports the 133 Mhz FSB.

I also got a 2.8Ghz P4 Mobile with 133 FSB. It matches the 2.4Ghz in every respect except multiplier.

The problem? The 2.8Ghz Chip(Yes, I confirmed, it is 2.8Ghz) only runs @ 1.6! This is silly! is there any way to restore it to default?

you might try looking for a pin mod guide for desktop pentium-4's in the cpu/intel thread area... i think it's a stickey or used to be anyways... you will find alot of info there on how to possibly force the processor to 133mhz. I think the guide does the opposite 133>100 but I can't remember... even if it is so, you might be able to figure out how to reverse the effect by slightly modifing the mod.


of course a pin mod is kindof extreme and there is probbably a better solution like a hidden bios setting. try updating your bios to see if that will help.

The laptop automatically underclocks the cpu when you're on the desktop doin poop all. Unless you start doing something that takes alot of CPU power, it'll stay at 1.6ghz to save battery power and reduce heat.

I'mma gonna run CPU Burn in, and see if that bumps it up then.

Thats what I thought it was Apu, but I was running lots of programs, iand it didn't pop up, plus it says 1.6Ghz in theBIOS, not just windows .

1.6 @ 100% CPU load.

Multi @ 12, FSB @ 133.
