Disabling 1 core in quad disables cool n quiet?

post #1 of 16
Thread Starter 
So I have a quad core PII x920 in my laptop. (x920 BE @ 2.3GHz)

I don't need 4 cores, and feel that it is overheating my laptop (since I upgraded it from a dual core).

So I'm able to disable cores by software (not BIOS since it doesn't give me the option to), and turn it into a triple core.

However, my CPU according to CPUz no longer down throttles to 800MHz - it always stays at 2300MHz. Does disabling a core via software disable AMD's Cool N Quiet down throttling?

This happened to me once, when I disabled 2 cores and CnC wouldn't work for a few days no matter what I did. Then it started working again suddenly.

How did you guys disable it? I'm doing it with the MSCONFIG in software, not in BIOS.

Also, I'm doing this with a laptop PIIx4 BE...is it the same for laptop cpus?

Totally unrelated to the topic, but I see you have excellent taste when it comes to forum account names =]

You will have to do it in your BIOS, or go into Power Options in Control Panel, and switch the settings to "Performance"

I think he's looking to keep CnQ on, but disabling one core of his quad is turning CnQ off. Thus, his dilemma.

It's possible that a BIOS update would fix that.

To OP, I would look to see if there's a possible update for your BIOS, and apply the latest one to too if this fixes your problem

Nope srry, it's a dell, and the bios updates are few and in between. I believe I have the latest BIOS and the last 5 BIOS updates have nothing to do with hardware. =(
