Try my specs in my template i listed in my signature .. i am using BIOS 1201 and i suggest trying that BIOS as well.

1200 mhz memory is overkill and the only way to get it 1:1 is to run a 6 multi x 600fsb STABLE, but not many quad-cores will run 600FSB and mobo's/bioses.

So you will have to sacrifice memory mhz for CPU GHZ.. i running 8 x 450 ram is at 901 mhz ... even though it is rated 1000mhz memory ... even if i had 1100 mhz memory and wanted to sue it all . i would be trying to push all i had in hardware to its limits and that is not good for 24/7 daily usage even if it was stable.

Another thing is HEAT which is major factor in Ooing and stabiltity, you can only go as fast and high as the heat will allow and if to hot when full load .. then you have to sacrifice GHZ for heat reduction or get better cooling and try fir higher stable ghz with cooler temps.

Anyhoo .. look at my specs and download my template .. print it off and adjust from there.... 901 mhz on memory at 3.6ghz is fun and good enough for me.
