Q6600: Multiplier keeps changing (also about temperature on my lapped HS.).

post #1 of 13
Thread Starter 
Lately, I've noticed that my multiplier was repeatedly changing from 9 (what it should be) to 6. Mostly, it stays at 6, but flashes back and forth. Why is it doing this? At stock, a multiplier of 6 gives me 1600mHz... I bumped my FSB to 1333 which sets me at 3.0gHz, but it brings it down to 2.0gHz when it shows a multiplier of 6.

Also, I just lapped my Zalman 9500 (planning on getting a TRUE 120). The temperature definitely went down a few degrees. The thing is, it's idling at about 45c (my 4th core) to 50c (my 1st core). It seems awfully high compared to what I've noticed other people were sitting at.

Disable C1E and EIST in your BIOS.

They're two (in my opinion stupid) functions that throttle the CPU down to save power when the CPU is under very minimal load.

Turn off C1E and EIST in bios.

Okay, thanks. Can someone explain specifically what those do?

EDIT: Your edit answered my questions. Thanks, again. Also, what can I do about my temperature? Anyone with a Q6600 sitting at this high?

basically they will only take your CPU to full speed when it is under load. its a power saving mechanism. and its unstable. something intel worked up in their spare time.

The reason it does that is for energy conservation. You might want to keep it on so it conserves energy and lengthens the life of the chip. It does not effect performance

They lower your CPU multiplier when not under heavy load, the multiplier will jump to x9 under load, it's only useful in laptops to save power and keep temps low. It should be disabled because it may cause OCs to be unstable.

Your temps are so high because the 9500 is just not capable of getting you low temps on a Quad. You could try doing wire management and adding better fans or putting your computer in an area with lower ambients.

I suggest leaving CE1 on, but turning off EIST. Yes the 9500 is not meant for quads, the 9700 is.
