CORSAIR DOMINATOR 2GB (2 x 1GB) DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model TWIN2X2048-8500C5D

Pros: No errors on memtest, overclocks easily in the bios of an SLI Motherboard. Cool to the touch. Lifetime Warranty

Cons: Different versions of the same model of memory might not work together. Nobody tells you this and retailers don't specify which version they sell to you.

Overall Review: If you already bought one pair and are thinking about getting another set, you better make sure the second set is the same revision number. If they're different, they will work at 800Mhz, but your motherboard will not recognize them for EPP.

Pros: - Great memory out of the box
- Very sexy

Cons: I bought a set of these when I built my computer over a year ago, and they served me very well. However, I recently decided to upgrade my system from 2GB to 4GB, and purchased a second set of the exact same memory, only to find out that it isn't that simple. The *newer* set of memory has an *older* hardware version than the original set, and the computer will either fail to POST or blue screen while loading into Windows. Needless to say I am quite disappointed that what should be a simple upgrade process is going to be more complicated due to someone elses error.

Overall Review: None
