I am not sure.
What I can say is that the max 'clock' is 75MHz and the max
clock multiplier is X4, I looked at my jumper settings and I am
on 75MHz X 3 = 225MHz is that 75MHz my FSB? I am a little
unclear about this, but I am pretty sure it is not a 100MHz FSB.
The CPU clocks are listed as 50, 60, 66, & 75.

Again I am a bit confused over RAM too, I will quote from my
mobo manual (which I recently found!!)
"DRAM Type Supports EDO Ram. (both symetrical and
asymmetrical, "(whatever that means?)")"

Also:-
Access time:- 70ns or faster for FPM/EDO or 60ns or faster for SDRAM
(which indicated it does take SDRAM)

However I have only ever used 72 pin EDO RAM 60ns when I upgraded
I am unsure how the 60ns relates to bus speed.
Also the SDRAM I see on ebay seems to be 168 pin DIMMS and
they are not going to fit into my 72 pin slots are they!!!!!

I think 300Mhz is the max my mobo can manage :O(
