Motherboard only works with one memory chip

I have tried 2 different power supplies. Sorry about the chip/dimm
names. You know what I mean.

As things stand, either one dimm will work in any of the slots.
However, both of them will not work together. They are both Crucial
brand and from the same batch/spec.

DIMM, not "chip". DIMM = several memory chips.

Your soldering skills and equipment must be very good if you can swap
chips between memory modules like that.

Its a 650 watt power supply

No, it's not. Post a picture of its insides.

How do you know it's a real 650W PSU? Many manufacturers aren't
truthful, and one of the worst was found to overrate some of their PSUs
by about 100%. It's possible you have a PSU that's barely being
overloaded, and a quality 400W PSU would let your system work.

I don't see how a mobo can run with only one memory chip because
wouldn't that require either a chip that's at least 64 bits wide or
hardware to make it look that wide? All memory modules I've seen that
were at least 512MB in size each contained either 8 or 16 chips.

I tested them in all slots; slots all work with individual dimms. But
when I place 2 dimms (in separate slots of course) there is problem (no
post/display).

What does the manual say about maximum memmory and memmory per slot?

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

Actually I have done all the tests with HD etc removed (only ATX, cpu
fan plugged in) and the memory still work in pairs.

I will try changing memory speeds to see if it makes any difference.

I know someone who removed a 32MB x 8 memory _chip_ from a 64MB DIMM
when instructed to do so by a tech support person who meant to say
"DIMM" or "memory module." This is why I don't like using incorrect
teminology.

If adjusting the BIOS manually for very slow memory timings doesn't
help, try adjusting any termination voltage setting in the BIOS or
cleaning possibly dirty memory slot contacts by rubbing with an index
or business card soaked in 90% pure alcohol.

Is there any way you can test both DIMMs in another motherboard.

I had an instance where a pair of identical SIMMs or DIMMs worked fine
with other modules but not with one another. This was back when most
modules contained branded chips.

thats the type of person that should not have opened the case.
