>Adding 32MB SDRAM into PC's 1 expansion slot - PC sees it as 8MB. COMPAQ
website has others w/same problem, but support either points to their FAQ
RE: installing 3rd party h/w) or a procedure that has no effect (reset of
CMOS). SDRAM is PNY & was the "book match" for this PC. Fits the notched
slot perfectly, which means it meets most of the spec. Help!

It sounds like you have mixed 66 Mhz with 100 Mhz SDRAM
on a motherboard that either does not support the higher bus,
or needs to to be enabled for it.


To verify this you can install just one ram card to ensure they
are working correctly independent of each other.

1/66  +  1/100  =  0.02515  x  ( 10 ns ( wavelength))
32MB  x  .2515  =  8MB

This problem occurred in robotics applications
where data flow was bussed against each other.
This situation has been corrected on newer
motherboards supporting the 133 bus.
