Hi guys... I'm trying to get my ram to the advertised 1066mhz CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Newegg.com - CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Desktop Memory Asus P5Q Pro + intel e8400 I can only get the FSB to 490 and pass memtest+ Voltage is set to 2.1 as advertised. (I ran it at 2.11 to 2.2 and no go) DRAM Freq in bios is set to 981mhz. I've been reading reviews on newegg and they say they can get to that speed without a problem with this ram. Note: multiplier is 6.5 x 490. Cpuz shows 6 x 490 because of C1E halt state. I can set it to 8.5 x 400 fsb and the BIOS let's me choose varios DRAM freq speeds and 1066 is one of them. But my fsb is still 400. So my questions are: 1- I'm I doing something wrong? 2- Should I leave my settings at 6.5 x 490? would there be much of a performance difference to 533? 3- Is 6 x 490 better (almost stock speed) than 9 x 333? 4- is my ram still running at 533 (dual channel) if I set it to 1066 in bios even though my fsb is 400? What would be the optimum combination for you guys? Sorry for so many questions guys.. but the dram:fsb ratio thing is hard... Thanks!
