OCZ Gold 4GB (2 x 2GB) DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2G8004GK

Pros: Looks cool, 4G of RAM for CHEAP, works well. Works fine in XP - you'll see less than 4G, but it's better than 2G and you still get the Dual Channel benefit.

Cons: None so far.

Overall Review: I haven't had a chance to see if I can push this RAM at all, but it's very stable at stock speed on a Gigabyte X38-DQ6 board. Installed XP SP2 just fine with both sticks installed, and of course I only see 3.5Gigs because XP can't see more than that, but that's enough for now. Definitely worth the price and good enough until I can get something faster.

Pros: I've used many sets of this memory successfully. First time I've had an issue.

Cons: Had one stick fail last week. Went through the reviews here, found a service rep's reply to another user's fail report, followed the link and instructions. Five days later, I'm STILL going thru the RMA process. All I have is a 3rd update to my support ticket, and another form to fill out -- with all the same info I put in my 1st ticket.

Overall Review: The automated RMA system is pretty useless. Five days and I can't even ship the memory back yet, and I have no clue when I'll receive the replacement. We're a business. I can't have a system down for 5 hours, let alone 5 days. Sadly, I won't be using this brand again. I can't afford the downtime.
