Is there any software available to test the max fsb speed a computers memory will run.
I need to know this as my celly 366 wont go past 500 (90) and was thinking the Pc100 memory might not be what it should be.

No there isn't, typically PC100 SDRAM will do 100MHz almost 100% of the time (unless you got a bum module) You most likely hit the limit of your CPU.

I agree. If you are certain you have pc-100 memory then there is no way you shouldn't be getting OVER 100mhz out of that chip. Does it say -8 or -10 on the chip? If it doesn't then it is possible you got 66mhz memory there

If you don't have another machine anywhere else that you can test the chip in that runs on a 100mhz bus, then you might be able to run down to your local computer shop and have them test the memory out at no charge. I no many business' will do this.

Couldn't it be the bloddy AGP again...seems we've been here a lot lately...where does your 2/3 divider kick in??? or is it enabled maually?? checked it in SiSoft Sandra???

Here are some guide lines that can help determine if the SDRAM that you have installed is what it claims to be (PC100 or PC133)

Check the "module marking" which is screened somewhere on the DIMM. If it's a PC100 stick it should read something like this:

PCX-abc-def R
Where:

X = the specified clock rate, must be 100 for a 100MHz system.

a = CAS latency (in clock cycles), must be 2 or 3

b = tRCD - RAS-to-CAS delay (in clock cycles), must be 2 or 3

c = tRP - RAS precharge time (in clock cycles), must be 2 or 3

d = tAC - output valid from clock (in ns) must be 6ns

e = SPD-EEPROM version, either a 2 for Rev. 1.2, or the full "1.2"

f = 0 (zero) or blank, reserved for future use

R = registered, buffered DIMM
