The 21 multiplier is with turbo boost. Turbo boost changes the CPU clock ratio by 1 mulitplied by the base clock.
So what your seeing is just stock speeds with turbo enabled or just always on. If you're still running a previous BIOS I don't think you have the option to even correctly use turbo boost. In the previous bios there was no option to enable it and no option to turn on EIST. Therefore, it was just always on. This is how it was when I first received this computer running Vista, it was always running at max speed like what you're seeing..
The 920 processor has two bins or two turbo modes:
Base/Stock 20x133 = 2660mhz (2.66ghz)
1st Turbo (4 cores) 21x133 = 2793mhz (2.8ghz)
2nd Turbo (1core/single thread) 22x133 = 2926mhz (2.93ghz)
You should remember that it is multiplied by the base clock, so when overclocking I think it would be best to just leave it on and when you stress test for stability it will run in turbo mode which should tell you that it will be stable all the way up to turbo. Unless you turn it off, then If you turn off turbo, EIST, etc... the multiplier will not go above 20x on this board.
As far as overclocking goes on this board, I am running the modded bios from the other thread here but there are still no options to OC, but there are more options that are needed in the Frequency/Voltage section. It does have options to force the QPI to 6.4 and to force the RAM to run at 1333, but they do not work or there is no change. Only way to OC as of now with this board is to use Setfsb to raise the fsb. I was able to get mine to 156.
You should get the Turbo boost monitor from intel to see the turbo boost yourself: http://www.intel.com/support/processors/...031038.htm
