but since I'm a first time builder I don't know if it's any good. Can anyone tell me what brands are the reliable ones? Any suggestions are appreciated but I'd prefer a RAM that has 4gb and is near the same price range. Thanks all!
The difference is the CAS rating. You would be better off getting the CAS 7 kit techmo34 linked to over either of the CAS 9 kits you've mentioned. The price is only slightly higher for the CAS 7 RAM. It's worth it IMO. The lower the number the better when it comes to CAS rating (CAS 7 is faster than CAS 9).
