I am trying to increase the RAM in my eMachines T2825 from 512M to 1G. It has a slot for the other 512 that I am trying to put in but when I do I get this series of beeps and the monitor doesn't even come on. Both 512's will work by themselves but not together. I did try and use both in the slot that was empty by themselves and neither work. I had the same problem with the original motherboard and sent it to eMachines where they replaced it and the processor...but I get the same results when trying to expand the memory. I have tried at least 4 different memory sticks and the last one I ordered from eMachines (for $150 no less) and it doesn't work with the original samsung stick I have. The one EMachines sent is Micron. Anyone heave any ideas?
