InsideHW.com did comparison of four DDR2-1066 dual channel memory kits

We have decided to perform comparison test of memory modules that are certified at 533MHz or more precise at DDR2-1066 standard. We provided for this test several Dual Channel kits with 2x1GB capacity. Choice for this module speed came as consequence of the fact that most motherboards support 1066 standard. Capacity of 2GB RAM memory became standard also so our decision was actually led by these facts. We wanted to compare and determine what memory gives the best performances at default settings and of course, to determine overclock margin for each module. As you can see in table with specifications, tested modules have three the most popular chips lately.
