I have an old PC I'm tinkerin with for the garage and I have a couple questions about RAM.

It has an SIS741GX chipset with an AMD 1800 CPU. I also have a spare 2300 AMD CPU.

It says it supports "DDR 333/266 SDRAM, 2 slots up to 1gb each (2 gb total).
It currenty has one stick of 1gb 266 PC 2100 ram in it now and I'm looking to increase it to the max. of 2 gb.

Question time: Is 266 and 333 ram interchangeable? Can you mix one slot of 266 with one of 333? Will upgrading both to 333 make it any faster?
And what's the deal with server vs. PC RAM?

I don't want to buy something that won't work or won't help.

Tanks in advance.
