Query: 1GB Memory Sticks - Corsair

I received 2 of these 1GB memory modules packaged nicely.They arrived quickly (within a few days).I used them to update my Dell Optiplex (small form factor) GX620 Dual Core machine. The price was quite reasonable.They were the correct type and the update went smoothly.No problems at all with these...very smooth install and they are working fine!
