[kwlug-disc] System Testing LiveCD, cpu-z equivalents, etc.?

[unsolicited]

What's out there for doing system testing / exercising, etc.?

I can run memtest86+, but I'm not sure that it's accurate in terms of 
detecting correct memory speeds for the latest and greatest hardware, 
let alone the other areas of hardware it doesn't cover.

In these cases, the system has no OS yet, so the facility has to be 
bootable.

Suggestions?
