I wish I knew the answer to your question. I have a 5009 with kind of the
same problem. I have three 128 sticks in now and can't add a 256 either.
Same low density DIMM. Won't get to the bios either. I hope someone has an
answer for you because it would probably help me as well.

Agree. A 256MB low density DIMM should have 8 chips on each side of the
DIMM/ At least that's the most common configuration.
Here is a link to Crucial memory guaranteed to be compatible:

The 256MB stick is very likely high density.

An SDRAM with 9 chips has ECC, which is not compatible with this system.

What is concidered low density? Well, this chip is single sided. I
also tried a double sided chip that has 9 chips, and that was a 128MB
chip.- Hide quoted text -

Ok, looking at the 256MB stick of SDRAM, all 8 of the chips are on one
side. The 64MB chip is the same with 8 on one side as well.
