How to determine memory type

Specs: Win 98SE, Duron 1200/512MB

Can anyone tell me how to determine whether my memory is PC100 or PC133?
I have 2 sticks of 256MB, I am pretty sure that the second stick I installed was PC133, but I cannot remember whether the original stick was PC100 or PC133. Currently running a Duron 1200 with 100MHz FSB but will be upgrading to an Athlon XP Mobile 2600 with 266MHz FSB and if I have a PC100 stick I will replace it with another PC133. Hope this makes sense!

Thanks

Get Everest Home Edition here:
http://www.lavalys.com/
Instal and run it.
In the left margin expand the menu item for Motherboard and select SPD. The result in the info panel will tell you everything you want to know about your ram. Handy program for identifying most of your hardware without having to open the case.

Hi,

Does your motherboard support an AthlonXP?
To get full usage of the 2600+ you would need DDR ram, and from what limited info you've given, your system only is capable of 133FSB.

Downloaded Everest, will run it tonight.

The standard XP 2600 will probably not run on my mobo as it requires 333MHz FSB and ideally DDR memory. The Mobile XP uses 266FSB and should be compatible with my mobo and PC133 memory.

Thanks

OK
Have run Everest, selected Motherboard/SPD and got a completely blank page!
Memory read comes out at 487MB/sec, write 251MB/sec, latency 309.6ns, timing 2-3-3-6
Any other suggestions please?

Thanks

OK, I am dumb!
Just been into the bios and reset SDRAM speed from 100MHz to 133MHZ, result:
Read 650MB/sec, write 316MB/sec, latency 272.5ns.
Guess it must be PC133 memory!
