I am looking at getting RAM for my pc, which I have posted here before about. I have a DELL DIMENSION 8200 and I know which RAM I have to get, but I am wondering what difference it will make if I upgrade to ECC vs. NON-ECC RAM. Dell's website calls for NON-ECC RAM for my pc, but I am hearing I could put in ECC and it wouldn't really make a difference. I currently have 256 (2X128 and 2 CRIMMS) and I want to go to two 512 sticks and move the 2 128 sticks to where the CRIMMS are currently. Could I get ECC for my dell and do it this way, or do I need to go with non-ecc? Anyone have any ideas/explanations? Thanks!
