You should be aware that ASUS P/I-P65UP5 among many other ASUS boards will
not work correctly with very high density SIMMs - particulary 64MB modules
which have more than 24 chips per module.  This is stated in the
motherboard documentation.

Does anybody have a good source of 16x36 SIMMs built from fewer than 36
chips per module?  I have several P6NP5 (uniprocessor) boards that work ok
with two of these modules (128MB) but can't seem to handle 4 of them at
once (for 256MB).  I've ordered a Tyan board to experiment with, as I have
quite a few 36cpm 64MB SIMMs around. 

ASUS says their boards support 64MB SIMMs but I wonder if that is
"theoretically, if you can find 64MB simms made of 24 or fewer chips per
module" ???
