Hello,
I have a very similar problem: I have a Pentium 200MMX on a 5I-VX1C (not
sure of the company) motherboard running on i430 VX chipset. The VX can
support 128 Megs of SDRAM (only Cached). My mobo has 4 SIMM slots and 1 DIMM
but if I put in a DIMM,I can't use any SIMMs. I have 2 16 Mb SIMMs and I
want to put in more RAM : 64 or 128 MB on a DIMM because the SIMMs are just
too expensive. I've already bought a 256 Mb PC133 stick before I knew the
mobo couldn't even support it all ( I can return it though) and the
motherboard is only seeing 64 Megs of it.

First of all is this safe? I've run memtest86 and Prime95 and it seems
stable but I'm not sure where the problem is nor if this could damage my
mobo.

Second, was there a type of SDRAM before PC66 SDRAM. My mobo manual says it
supports SDRAM but I don't know if PC66 is what it means. And I've heard
that you can usually put in PC133 or PC100 anywhere a PC66 can go, at least
in theory.

I'm gonna try next a 64 Meg PC133 DIMM to see if it stills divides by 4 or
uses it all; if it gives me only 16 Mb, I'll probably end up sticking with
the 256 Mb DIMM because it would be cheaper than buying SIMMs (and I can
even sell the used ones)

A lot of you might suggest me to simply buy another computer but I want to
keep this one until something I ABSOLUTELY want to do ABSOLUTELY can't be
done with my computer.

I welcome any advice or suggestion.

Frank
