What memory can I use

[Fiero]

My computer uses a Cyrix 166 CPU and has a 3.3 Unbuffered 168 Pin DIMM memory slot.

Can I use PC 100 memory with this this motherboard??? It seems to be cheaper than the 3.3 volt stuff, plus I can use it in another system when I upgrade the MB and CPU.

I think your motherboard will not support PC-100 RAM. Check you motherboard manual or manufacturer website.

Was the same with my oldie Atrend-1020 mobo... the PC-100 ram was not detected and it crashed when it booted.

Best advice to you would be to wait for the upgrade of MOBO and CPU - the PC100 RAM chip would be utterly wasted on that CPU. Unless you need the system up right away to pull some important data, I wouldn't risk it because you have a chance of damaging the RAM by putting it in a board that can't handle it.

Also, that CYRIX chip is extremely slow for floating point calculations which makes it bad for things like games & graphics.

Move on - get the next mobo & chip - then worry about the RAM, unless you've already bought it. After all - we just hit the 700 mHz processors and the 133 PC bus is out there now.... That 166 Cyrix will only slow you down - doubt you'd get more than $20 resale for it now.
