I dedided to go with this stuff: SAMSUNG 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600... There are great timings and speeds being achieved with it! http://www.techpowerup.com/forums/showthread.php?t=159320 http://www.overclockers.com/samsung-ddr3-1600-ram I'm hoping to get mine as high as I can for clocks on my Gigabyte X58A-UD3R. Are there any tips for OCing RAM or anything like that? I'm thinking of starting at around 1800, 9-9-9-24 1t @ 1.5v. Any other suggestions?
