Why would I wan't to disable a feature that protects your system.
Do you disable the brakes in your car?
Yes I can oc to 3.680Ghz and stable. Logging with throttle watch I can see that it reaches this at 100% load and no throttling, but when the load is less than 100% it goes back to 3.400GHz.
It's fine and works for me.
My power scheme is set to "always on" and it doesn't disable it.
On my setup you can disable EIST in bios - never have though, no need.
Anyway this is going off topic.
Timbob87 obviously has a temp problem with the cooling on his P4 640.
