techPowerUp! has posted a review on the G.SKILL F1-4000USU2-2GBHZ PC4000 memory
The G.SKILL F1-4000USU2-2GBHZ unite overclocking and 2GB. They almost overclock like the best 1 GB Dual-Channel kits, but offer double the amount of capacity. We reached 275 MHz (DDR550) at low 2.6V. If you want the smoothness of 2 GB and also overclocking, they can be yours for about $245, which is an excellent price.G.SKILL F1-4000USU2-2GBHZ PC4000
