KX7-333 won't accept more than 512M

I have an Abit KX7-333 motherboard. It is supposed to accept up to 3.5G
of RAM, but it only works with two 256M chips. I've tried two 512s, a 1
Gig, mixtures of them and the 256s, but the only way the computer will
start booting (show the screen that says "Press Del, etc., then continue
the boot proceess) is with the two 256M chips. Any other combo, no joy.
I need more memory - is there something we're doing wrong when adding RAM?
There don't appear to be jumpers to set, so what are we missing?

Thank you,


Alan

Check bios ram settings. Set to manual and the lowest possible speed
settings to start with.

You probably have high density RAM modules. Usually, these are
identified by the fact that there are chips on only one side of the
circuit board. Older chipsets can't see the extra memory because of the
way the chips are configured on the DIMM itself.

If you plug it in and the computer sees only half the memory, it's very
likely due to using high density chips.

Your best bet to get something that's compatible is to go to
www.crucial.com and use their memory advisor to see what's compatible
with your motherboard.
Pay close attention to the chips configuration, I.E. 64x16 64x64, that
type of info.

Here, I did the work for you. This lists the memory modules you can use
on your MB:
