NO, NO, NO, NO, NO....

Very few, I repeat, very few mobo allow installation of SIMMs and
DIMMs. Let me clarify.

DIMMs  are available as SDRAM AND EDO RAM. SIMMs are EDO RAM (or
older). EDO and SDRAM operate under different voltages, i.e. 5 v and
3.5 v (or 3.3v, I not sure of the top of my head)  respectively.

If you want to combine 72 pin SIMMS AND 168 pin DIMMs, unless you mobo
supports DIMM voltage indepent of SIMM voltage (again, I repeat very,
very few do.), then you must use EDO DIMMs which are very hard to find.
And some mobo do not even suport this combination of EDO SIMMs and
DIMMs. Furthermore, if you want to use SDRAM DIMMs you must change the
voltage via usually a jumper on the mobo.

So with out documentation to do verify any of the above, I would stick
with SIMMs only.

<< Subj:              [PCBUILD] SIMM or DIMM?

 I have no documentation for my motherboard so I'm
 hoping this list can help me with adding RAM to my
 Pentium.  I have two empty 72 pin SIMM slots as well
 as an empty DIMM slot.  I currently have two 72 pin
 SIMMs installed (16MB).

 Can I combine a DIMM and SIMMs and have them work
 together or do I have to buy more SIMMs if I want to
 use my existing RAM?

 You most likely can add a DIMM and it will work with your system along
with
the SIMMs.
