nice 1 !!

so i have OCZ3P1600 4Gk, 1600mhz 7-7-7-20 1T@ 1.92V..
is it good or i need to change it to 1333 and get 5-5-5-24 1T?

NB = 2.2ghz (mobo can't go more than that )
HT = 2ghz

Sorry for late response, I haven't checked this thread in a while.

Most likely you can not achieve 5-5-5 timings @ 1333mhz. You should be able to pull off 6-6-6-24 or around 6-6-5-20 @ 1333mhz and be able to raise the NB some. I'm surprised your NB speed can't go higher

Start off with 6-6-6-24 and slowly tighten the timings (ex go 6-6-6-24 to 6-6-5-20, then if that is stable 6-5-5-20, etc..). My ocz kit that was rated 7-7-7-24 @ 1600mhz did 6-6-5-20 @ 1333mhz. Every kit is different though, juts play with it until you get the best speed.

I have messed around with ddr2 and it also likes high northbridge frequency and lower HT link. I don't know what NB-CPU speed is but your NB frequency should be as high as you can get it, and keep your HT link at the stock of 2000mhz (or maybe 1800mhz, I'm unsure on that processor) for best performance.
