Hello! Hope someone can help me out with my problem.. I have an Intel i7 920 on my Gigabyte EX58-UD4 motherboard and i'm having the following problem; i cant seem to get my system self-overclock/underclock depending on the system needs at a given moment. What it does, is run at 2,8 Ghz [multiplier value = x21] (while stock speed is 2,6Ghz [multiplier value = x20]) all the time, idle or under load. It never drops below that clock speed.. When i first got it working, i remember it used to under/overclock itself when needed. It used to go from like 1,9Ghz to 2,9Ghz when it needed to. I have been experimenting with BIOS settings since then and i probably messed up somewhere, so now i cant find a way to restore this feature (called sidestepping i think?). Of course, i already tried restoring BIOS settings to "Optimized Default" values, but that didnt seem to make a difference. Any ideas pleeease?
It's called Speedstep, and there's a few name depending on the BIOS. It can be called EIST (Enhanced Intel SpeedStep Technology). If you can't find any of these, you can also try an option called C1E.
EIST only underclocks the CPU when it idles. I think you are also referring to the Intel Turbo Mode Technology, which we covered here - Tech ARP - Intel Core i7-965 Extreme Edition Quad Core Processor Review and here - Tech ARP - ED#104 : Intel Reveals More Details On The Core i7 Processors
