I have read a miriad of forum post. I cannot get all 4 sticks to operate at the rated speed of PC2-8800 without numerous errors on memtest, and usually cannot get into Windows (7-64). I can get any 2 sticks in any 2 slots to operate fine at 1066 with virtually no adjustments other than setting the voltage manually @ 1.8 for the dram. The settings below under the title 4GB,1066,5-5-5-15-2 work with any 2 sticks. However, I can get all 4 sticks going, again with the same voltage adjustment, and tighter timings with no hassle at all PC2-6400. These settings are under the title 8GB,800,4-4-4-12-2. I have tried upping the MCH to 1.4, upptin the tRFC to 80 or 88, etc. Help!
