how to know speed of slot 1 processors?

It's normally silk screened on the top edge of the SECC package, although
Intel used a couple of different package designs during the Slot 1
production run, so you might have to pull the CPU out of the system before
you'll be able to see. In the case of some of the later SECC2 P!!!'s and
most of the Celerons, it's written on the PCB itself. If you have the
processor in hand there's no reason why you should have to ask.

Mind you, I fail to see why you can't determine what processor you're
running by a non-invasive method. A utility like CPU-Z should be able to
tell you what you need to know.

There's some blue lettering on the top edge of the processor. It's a
string of numbers and letters that looks more like a bios string and I
can't decipher it. Part of the string reads ...X300... so I thought
300mhz, but that's on all my PII processors yet they are of different
speeds. I don't see anything so clear as say the last 3 digits from the
back of a PI chip.

Sorry if I wasn't clear.

These are parts of systems I am putting together thus no software is
installed yet. I can pull the processors out for inspection, but run
into the problem mentioned above.

Thanks for your help.

Look for the sSpec number. It's a 5-digit alphanumeric identifier
beginning with 'S', and will be printed on the top edge of the
processor. Plug it in here:

It's probably the product code, and thus shouldn't be overly difficult to
interpret. The clock speed, front side bus speed and amount of onboard cache
should all be included in clear numbering.

SECC2 cartridges (Celerons, Pentium!!!'s and later Pentium II's) have their
clock speed, bus speed, S-Spec and place of manufacture on a white label on
the "back" (non-processor side) of the PCB. SECC CPU's have basically the
same information printed on the top of the plastic cartridge. If you can't
see it, either it's been deliberately scrubbed off, or you need to look
harder.

If you quote the entire string we should be able to tell you what each
section means.

You wouldn't, as product codes from the Pentium II onwards got far more
complex with the increasing variety of bus speeds, cache levels, product
lines and so-on.

Yeah. Like the Slot-1 Celeron I have here

08471058- SL2WM
300A/66 COSTA RICA

With a little intuition we can pretty much rule out "COSTA RICA" as a
speed, as well as 08471058 and SL2WM (which is the S-Spec).

Which leaves 300A/66 sounding suspiciously like 300 Mhz on a 66 Mhz FSB
because that's what it is.
