Getting the Processor Class and Speed

If the POST process tells you the processor class and speed, use that information to record on the label. If not, you can boot from the WHAZIT disk or a MEMTEST disk to determine this information. Failing that, you will need to look at the processor itself to make the determination.

It helps to know the processor types that we tend to get at FREE GEEK. Here are some Intel chips:

Pentium

These ones are seated in a ZIF socket, typically a Socket 5 or a Socket 7. Since they are usually covered by a heat sink, you will have to unlatch the heat sink, release the lever for the ZIF socket, and pull the processor out. Look first at the bottom of the processor for a model number. At the end of the model number, the speed is indicated. The model number is often on the top of the processor instead, and you may need to remove the heat sink to see it. Standard speeds for Pentiums are:

75
90
100
120
133
166
200
233

Pentium Pro

These ones are like Pentiums (above) but are in Socket 8s. Standard speeds for Pentium Pros are:

180 ?
200
233

Pentium II

These ones are in slots attached to heat sinks, and you can usually read the speed from the model number on the heat sink. 8s. Standard speeds for Pentium IIs are:

233
266
300
350
400
450

Pentium II XEON

These ones are in slots attached to heat sinks, and you can usually read the speed from the model number on the processor. Standard speeds for the PII XEON are:

400
450

Pentium III

These ones are similar to Pentium IIs.

450
500
550
600
650
700
750
800
850
900
933
1000
1100
1130 (recalled)

socket 370

1133
1200
1266
1400

Celeron

There are three different classes of Celeron. The first kind are similar to Pentium IIs. The second kind are similar to Pentium IIIs. The third kind are similar to Pentium IVs.
