Okay those of you having problems with DDR2 1200 try this: Move rams into white slots, set cpu skew to delay 100 (I agree finer adjustments eg. 50ps would do wonders), set nb skew to normal. Set your ram to max volts (2x2GB skills don't suffer from over-voltage even up tp 2.80v) ie. 2.100v - make sure this is actual. Set NB to 1.4.5 - 1.5 (for FSB 450). Advnace both DRAM CLCK SKEW Channels A/B to 300. Set Ai Clock Twister to moderate.

I would test this myself, but I no longer own this board. Please give me some feedback; I'm more interested in MCI Memtest (Windows) than Memtest 86+ under DOS mode. Thanks.
