Asus P6T Deluxe Discussion Thread

[unclewebb]

The Asus bios is misleading. With a Core i7-920, if a bios has a 21X multiplier option, then it automatically has to enable Turbo mode to get it. The default multiplier for an i7-920 is 20. The only way to get beyond that is by having the turbo feature of the processor enabled. That's why the 21X multiplier can throttle back to 20X depending on what bios version you're using. This is triggered by core temperature and power consumption, usually when you get up around 4 GHz and are running something very stressful like LinX on all 8 threads. Many users here have successfully cross flashed their v2 boards with the 0006 v1 bios so if you ever have this throttling issue with your new board and want to fix it, there's a solution for you.

On many boards EIST / Speedstep also has to be enabled for turbo mode to work correctly. If you don't manually enable it then the motherboard might enable it for you if you have selected the 21X multiplier.
