Identify RAM chips and test programs?

Two quickies:

What's the easiest way I can identify the chips in my ram? I just got a set of new firestix in (FSX800D2C-K2G) and was wondering if they are indeed D9. I'd like to not have to force the heat spreader off if there is another way.

Also, I've been out of the OC loop for a few years. Is the basic memtest86 still the best way to crunch ram and identify bandwidth?

Thanks,
Froz

I believe the buffalo firestix are d9

also, could you tell me how they work, im considering getting them
