OK, So I had Windows 7 a few months back. I had this problem, and forgot that its why I went back to vista.
basically, ive been on Vista 64 bus for the last 2 months. Havent changed my computers settings at all bios wise. So under windows vista my clock settings are:
(motherboard DFI x58 and proc i7 920)
1.36v vcore
1.36v vtt
195x21x = 4.1ghz
1950mhz ram
195 BCLK
Every day I went into vista, and my clocks stayed at 4.1 ghz. i could 8 core prime, no problem, watching CPU-Z it never changed.
now I just decided to try RC1 vista, and am in windows and I see this instead....

Now, I will go through what I have checked.
1.) power profile. I have tried High performance and also built a custom one. no go.
2.) I rechecked my bios settings, I even booted into my old vista install as its on another disk and settings are fine and 4.1 runs flawlessly.
3.) when i boot, my post screen shows 195x20 = 4.0ghz. When I get into windows it becomes a completely different story.
4.) I have disabled C1E state completely. It should not be throttling down, as it is disabled on the hardware level?
5.) I had to leave EIST enabled, as thats the only way turbo will work 24/7.
6.) if I disable EIST, and boot into windows, I will get 195x20x = 3.95Ghz.
7.) if I leave my PC at stock settings say 133x21 w/ stock voltages and go into windows 7 it will do 21x.
8.) ive ran benchmarks that show my performance is really at that low of a level w/ 12x multipler, so it is not a CPU-Z issue
So those are the facts I have figured out on my own. For some reason it appears windows 7 throttles down my overclock, like its not safe. " I dont like it when an OS goes big brother on me, and tells me, I dont think that overclock is safe, so you cant do it sorry, i am going to limit you to 195x12 = 2.4 ghz, have fun."
This has been an issue on all windows 7 installs ive done up to RC1 7100.
Anyone have any idea how I can nip this one in the butt? Anyone know what could cause this?
Id prefer not to mention this, but I did have the same exact brand board that I RMA'ed, and prior to the RMA, i remember hitting 4.1ghz in windows 7 on that board with similar settings. Now I know what you are thinking, well it must be the board then? Well how come I dont have this issue with windows Vista 64 then? So id prefer you ignore this, but I want to be as accurate as possible.
Sorry if this is information overload, Its just really irritating me, and I would like to see this one small issue I have with 7 disapear. (well big issue for me right now)
