Hi George,
There is a bank of jumpers in front of the memory slots (on the front edge
of the motherboard) that needs to be shorted if you are using DDR memory.
They use long blocks of jumpers, and I noticed that when I changed them on
one of the boards I worked on that some of the inner metal pieces that
actually create the short between the jumpers came out. I had to carefully
reinsert them before putting the jumpers back on. The friend I was helping
had the same problem.
Also, there is a little jumper between the SDRAM and DDR memory banks that
needs to be removed. When jumpered it uses 3.3v for the memory, and when
open 2.5v. DDR is 2.5v memory. This can cause the same problem.
Hope this helps.
