i7 920 multiplier stuck at 20x

post #1 of 3
Thread Starter 
I've had my sig rig running stable at 175x21 for a couple months and today I noticed that it's running at 175x20 instead of x21. I went into the bios and the CPU ratio setting was still set to x21, and the target CPU frequency in the bios is showing the correct frequency. However during POST and in windows it's showing 175x20. I can set the multiplier to anything lower than 20x but not 21x. I was on the 0505 bios so I updated to 0702 and re-entered all my settings but it's still the same.

Anyone can shed any light on this? Thanks in advance, BIOS template below, thanks to LGX.

It appears that you have turned off turbo. The max muti a 920 is 20 with turbo enabled it bumps it to 21

The weird thing is I've had my bios set exactly like this ever since I dialed in this overclock a couple months ago. It's always shown up as 175x21 in Windows (CoreTemp, CPU-Z), also during POST. Only noticed today that for some reason it decided to go back to 20x, I haven't changed a thing in the bios.
