Summary: bought 3 to upgrade an older machine, bought the right spec parts but couldn't get any 2 of them stable... put old RAM back in and everything was fine. Will buy something else, somewhere else.
Summary: I have dell dimension 3000 and windows xp. My computer was running slower and slower, web pages like yahoo were very slow to load, videos "froze" as they played, etc. I finally found the dell specifications for my computer (1GBx2 maximum memory), so I got this memory (much cheaper than at the store and it only took about 5 days to get to me thru the mail).
Summary: Before I bought this product I wanted to know if my system could use it and after careful research it did and the PNY Optima 1GB DDR 400 MHz PC3200 Desktop DIMM Memory Module MD1024SD1-400 helped my computer to run Windows 7 more efficiently. The computer memory upgrade helped to improve the overall performance of my PC.
Sales pitch said compatible but isn't, now PC wont boot w/original hardware

Summary: Title says it all. I'm screwed. Description stated it was compatible with my Dell Dimension 4700 but wasn't and now the original mem stix won't boot either. Did not attempt to exceed capacity as it is listed as 4GB for this machine with the standard 266 Immediate start up yields 4 internal buzzes, followed by 2 more. Nothing on screen. I tried each stick alone to see if one was bad, but all failed. Then returning my originals to the slots, same symptom.
