200x20 for 4ghz and 1600mhz ram.

In order to acheive 2000mhz RAM, do i need to increase the QPI/Dram ?

My factory settings are supposed to be : 2000 9-9-9-24 2T @ 1.6v
The '20' multiplicator is not advised to get a stable overclock easily with the i7 920 (unless you add Turbo).
Go for 19 or 21.

e.g.:
21 x 191 (4GHz)
DRam Freq: 1914
Uncore Freq: 3829
QPI Link Freq: 6893
DRam Timings: 8,9,8,24,1N @1.64V (maybe more needed but seems ok here).
Then you got to find the voltages for your board/cpu as it's never the same.
