Newbie question: PC100 RAM - can my PC only use this?

Hi there,

As you can tell from the subject line, I'm not so bright about hardware!
I want to add RAM to my PC and I've seen some good deals on ebay - but I'm
not sure what to buy. I recently bought 64MB SDRAM PC100 - purely because
that was the exact description of the 64MB that came with my PC when I
bought it. I put it in and it went OK - I really notice the vast
improvement it's made to the performance.
Now I want to have 256mb installed (as opposed to the 128MB currently
installed) but the choices of RAM of the type 'PC100' aren't so plentiful.
I've seen a lot of PC133 but I don't know if my PC can use it. I use AIDA32
to monitor my system and it gave me the following information. Can someone
please tell me if I can use PC133 or can I only look for PC100?

Thanks, I could really appreciate some help,

Joanna

I would just stay with the PC100 - get Crucial brand, a 256mb stick
should work just fine. I think 384mb is the most RAM you can use.

I use PC133 SDRAM on machines that call for PC100 as it's backwards
compatible. So it should work just fine.

Not necessarily true, most PC133 in the market now is high-density,
while most boards that were spec'd, use PC100, can only accept
low-density. PC100 in 256MB module(s) would be the preferred upgrade,
but those are also becoming less common, it may be easiest to buy 2,
128MB PC100 modules, if the goal is only 256MB.
