How to tell true processor speed?

[GizmoFreak]

How can I tell what speed my processor natively runs at?

I inherited a computer, which I think may have been tweaked with. It seems to run fine at both 600 mhz (100mhz bus) and 800 mhz (133mhz bus). But I can't tell which is the true speed.

This is a Pentium III chip.

Is there any way to find this out?

I don't think Intel made an 800 Mhz P3 with a 133 Mhz FSB... did they?

Hmm, I have no idea about that. So does that mean it's probably a 600/100 overclocked to 800/133?

I have a Pentium 3 800EB which has the 133mhz front side bus and a 800mhz clock.....if it says the EB maybe it is the 800mhz clock it is native at.

P3 800 "EB"

Any way I can find out which one my chip is?

Will it say on the chip? I'd prefer not to have to take the heat sink off.

Is it a Dell or Gateway or something? I think most of those companies put labels on the back with a number where you can look up the exact system configuration on their web sites.

What OS?

XP will tel you..

I had a 2.4b@3ghz and it would show under My Computer - Intel P4 2.4ghz
P4 @ 3ghz

Or something to that effect

WCPUID or Cpu-Z may do the trick.

Not always... my friend's Dell Notebook with an 866 Mhz P3 says "866 Mhz Pentium compatible" or somethin like that... says nothing about the actual model.

E = on die cache
B = 133fsb

can get p3 E's or p3 EB's but i dont think u can get just a p3 B

use THG_CLOCK the same prog that blew the secret cover of the Neo's trick clock

CPU-Z should be able to tell you the model/id/stepping info, which you could hammer into Google to find the specs. Like mentioned, "E" = bonus cache, "B" = 133FSB. You either have a 600E or an 800EB.
