BlackOps: CPU Multiplier Issues / CPU not running at full Speed
First of all please use tools like CPUz and Everest to doublecheck your CPUs current clockspeed.
Once you confirmed there is efinately something wrong with the CPU clockspeed, please update to the latest BIOS, enter the quantum force BIOS menu, and set EIST to "native" and core frequency unlimit to "enabled". You should now be able to select higher than default multipliers with QX and XE cpus and they should stick in windows as well. If the multiplier doesnt stick in windows then please make sure you set the windows power managment to performance, so that windows doesnt clock your cpu down to save power while its idle.
In windows XP:
Click on "Start" -> "Control Panel" -> Performance and Maintenance -> Power Options -> Set to "Minimal Power Management"
Microsoft Guide on Windows XP Power Management
In windows Vista:
Click on "Start" -> "Control Panel" -> System and Maintenance -> Power Options -> Set to "High Performance"

At CPU temperatures way below zero the cpu sometimes changes its Multiplier back and forth on the fly.
This is a bug caused by booting at too low temperatures, and booting the CPU at less deep temperatures and then reducing the CPU temperature when windows has loaded apparently fixes this problem
Check if you can adjust the CPU Multiplier with Crystal CPUID, this neat little tool can be very helpful if you run into multiplier issues :)
If it doesnt work or windows keeps resetting the cpu multiplier, please make sure you configured the BIOS and windows power management panel properly.
If you still have issues related to the CPU Multiplier of the CPU Clockspeed beeing lower than what it should be, please post in this thread or send me a private message :toast:
