Hello ED, >I've just added 256 mgs of RAM and am wanting to add more memory to my >PC. There are no more RAM slots. There are 2 more smaller slots (about >1/2 inch smaller than the RAM slots). What kind of memory would this be >and what kinds of prices are we talking about? Those *may* be for the older 72-pin SIMM style memory, but to the best of my knowledge you can not mix 168-pin PCxxx style memory and 72-pin SIMM style memory in the same machine. Perhaps some mobos will allow this, but I don't believe so; for one thing, the speed difference would cause problems.
