What do you have for sale by the way of DDR2 ram for a desktop pc? I have a older machine I'm juicing up and need 4 GB more of ram for a total of 8 GB. It uses Corsair CM2X2048-8500C5D @ 5-5-5-18 right now. I would need 2 more 2 GB sticks of the same or I would be open to 4 sticks x 2 GB of something else (faster ram) if the price is right/? Let me know what you have laying around. U.S. only please.
