[RESOLVED] Older Pentium CPU Identification

[pistaugh]

Does anyone know how I could identify the speed of a Pentium 1 processor without putting it in a machine? The machines battery went dead and reset the clock speed to 100 mhz. Now, this processor MAY BE a 100 mhz processor, or it may be 200. We have both kinds in these old machines. Is there a way I can Identify the processor by the numbers on it? I saw on the Intel site there was a way to ID Pentium 2s, but I saw nothing about Pentium 1.

if you look on top of the chip it will have one or two letters about 4 numbers then a dash the number after the dsah is the cpu speed.

ex
ag5426-100 would be a 100mhz cpu
sa45654-75 would be a 75mhz cpu

hope this helps

All it says on the top of the chip is
"Intel Pentium w/ MMX tech"

underneath it says:

Intel Pentium w/ MMX tech
FV80503200
Q019 ES2.8V
A3
C6380906-5303
C (COPYWRITE) '92'95

hi, well then you have a 200 mhz MMX CPU. i have one in the shop here. it reads
FV80503200
SY060/2.8V

so the # after the FV80503 is the CPU speed.

Even if You didn't see MMX letters (for example,covered by heatsink),"SY060/2.8V" should point You at 2,8v core voltage...

No such thing as an MMX 100, only 166, 200 and 233. Laptops had 150 and 200 (not that you'll get many of those loose).

Yeah,that's exactly I wanted to say - there are only MMX (Intel) 166 and above CPUs with 2,8 core voltage...

There was also a 266 version, though it was ONLY available inr mobile. (I have one!)

I always just look on the underside for a sequence of #'s that match a known processor speed.

Also, I have a P5/120MMX notebook sitting in the shop, and we sold a Winbook P5/266MMX, funny how they make all these wierd chips for notebooks only!!!!!!
