I have a DELL Dimension 8200 with 1 GB made up of 4X256 sticks of non-ECC PC800-45 memory. I would like to increase this to at least 1.5 GB by finding some cheap RDRAM PC800 memory. However, there seems to be almost no non-ECC memory available on e-Bay, it is all ECC. The specs for my machine on Dell state that my machine takes non-ECC memory. A number of vendors indicate that this box will in fact take ECC memory. I had ordered ECC memory by accident once, and it did not work, however, we found out later on that the Samsung memory must be PC800-45 not 40 to work with my mother board, so it may have been the 40ns chips causing the problem not the ECC. Can anyone help me to understand whether the Dell will take ECC memory and work?
