I have a DP35DP MB with an Intel Duo Core. I'm currently running 1GB in DIMM 0 Channel A with no problem.
However, when I tried to upgrade by adding an equal 1GB DIMM in DIMM 0 Channel B, the PC no longer boots. No error beep sounds. Just a blank screen.
I then bought 2 matching equal 2GB DIMMs. I put one in DIMM 0 Channel A and the other in DIMM 0 Channel B. Same problem.
However, whenever I take out the Channel B DIMM, Channel A works fine with the 2GB DIMM.
But I really need 4GB of RAM and I can't get DIMM 1 to work.
