I bought 4 512 PC3200 ECC dimms for a dell precision 360 off of ebay. The seller did say it was "server memory" but I couldn't think of any reason why this memory would work in this machine (it supports ECC) and yet here I am. System gives a 1-3-2 beep code. I've tried it in different combinations (which has worked for me on some servers but not here). Any thoughts?
