Mushkin 1GB PC2-5300 DDR667
 

Priced at just $274 a pair, these modules are certainly worthy. If only our test motherboard did not maxout at 253FSB, we would probably see this kit running beyond DDR674! If you’re looking for high performance yet reasonably priced DDR2 memory kits, you should probably check out the Mushkin 1GB PC2-5300 DDR2.
