Bit-Tech published the first part of their 4GB DDR3 1,600MHz to 1,800MHz memory roundup
The G.Skill F3-12800Cl7D-4GBPI is a solid product with great performance potential and overclocking that's good value compared to the competition. We like the Pi heatspreaders and the lifetime warranty offered by G.Skill, although on the whole it's not an extra special product.4GB DDR3 1,600MHz to 1,800MHz memory roundup - Part 1
If you're interested in the super high end and want 2x2GB of memory - keep an eye out of the G.Skill F3-14400CL8D-4GBGT1 "GT1s" because they should be among the best there is. The price //should be very competitive, the cooling is actually no noisier than Corsair's Dominator with fans overhead but the RamOrbs will certainly cause at least some of you reading to turn your noses up - it'll be a field splitter.
Our recommended product has to be the Corsair TW3X4G1600C9DHX though. With virtually the same performance potential of memory twice the price, the best passively cooled memory solution out there, a lifetime warranty and a superb support forum, it's //the DDR3 product that bridges the gap between itself and DDR2. If you're upgrading to DDR3, on any board - get some of these modules and have some fun.
