Pros: Crucial makes great RAM. I have two of this module previously and had no problems. Great RAM for a great price.

Cons: The first two modules NewEgg sent were not the Ballistic chips advertised. NewEgg was great and refunded some money for their mistake. The new modules sent failed.

Overall Review: These two new modules ordered had problems. They had two different items numbers, and plainly mismarked on the chips (1-1, 2-2). One only tested at 512MB and the other tested at 1GB and then failed. Check the RAM you recieve because you might be getting super bargain RAM instead of Crucial.
