core speed and multiplier change??

post #1 of 4
Thread Starter 
ok, I got a q6600, evga 750i FTW, and gskill pc2-8000....

my ram was running at 800mhz...(it's 1000 mhz ram..) so I unlinked the ram setting, and bumped it up...

upon restart, my cpu core speed and multiplier (and apparently my vcore) have become unstable..(in cpuz).. I mean, I am watching it change..???

What gives??

BTW... maybe worth noting, i am currently running this on an antec 500W PSU

here are some screenies

Try disabling C1E and EIST in your BIOS.

They lower the CPU's multiplier when it's under very minimal load to save power, but it doesn't help.

This is completely normal. The feature that is causing this is called C1E and EIST. This feature is a power saving feature that you can find on almost all laptops, as well. Whenever your CPU is idle, your multiplier will drop down to x6. Whenever you put your CPU under heavy load (stress programs, gaming, rendering etc.) it automatically jumps back up to your max multiplier that you set in your BIOS.

You can disable or leave it enabled. It causes no harm either way.

yeah, I disabled the c1e... but I just did a test, when encoding, it's solid at 2400 and 9x....

Ok, thanks much...
