yep my dual 1.8 was extremely picky and had to reset cuda before
recognition. (also had to exchange what was first shipped since it
was not the correct mem)

My G5 which is a dual 2.3 using PC3200 is VERY picky about how the
RAM is seated. I reseated my sticks something like 26 times before I
got all 8 slots recognized and working simultaneously. Once they all
were recognized, I've never had another problem.
I think it helps if you press the CUDA button before booting after
each time you add or change RAM. I think your 1 GB sticks are
probably good. I'd try with ONLY the pair of 1 GB sticks over & over
again until they're recognized, and then add back the pair of 512MB
that seem to work better.

Hey all. Today got some additional memory for the above system but
the g5 1.8 ghz tower(pci-x) refuses to recognize them. I currently
have two 512 sticks that work fine, but the two new 1 gb sticks don't
show.
The packing slip identifies them as "PC3200 1gb DDR SDRAM 400mhz 184
pin memory", and the the stick labels both read "1 gb PC-3200 UDIMM
1RX4".
I did move the sticks in question around to the different matching
slots, but the computer ignores them.
I moved the two 512 sticks around as well, and they were recognized
in
each of the slots.
What gives? I thought I was careful in selecting the right ram.
