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 EVAL 2 hard 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

Pentium III XEON

These ones are similar to Pentium IIs. The XEON processor is used in server-class machines.

• 500
• 550
• 600
• 667 (proc of the beast!)
• 700
• 733
• 800
• 866
• 900
• 933
• 1000

Pentium IV

There are three different classes of P4s and many sub-types of those. The first kind use a modified socket 370 with 423 pins. the second kind use a socket 478 with 478 pins. Speeds on the first kind are:

• 1300
• 1400
• 1500
• 1600
• 1700
• 1800

Speeds on the second kind are:

• 1900
• 2000

Speeds on the third kind are:

• 2000
• 2200
• 2266
• 2400
• 2500
• 2533
• 2600
• 2666
• 2800
• 3000
• 3066
• 3200
• 3400

Speeds on the fouth kind are:

• 2.8GHz
• 3GHz
• 3.2GHz
• 3.4GHz
• 3.6GHz
• 3.8GHz
• 4GHz

Pentium IV XEON

These are the sub-types of Pentium IVs. The first type uses a socket 603 and has 603 pins. Speeds on the first type are:

• 1400
• 1500
• 1700
• 2000

Speeds on the second type are:

• 1400
• 1500
• 1600

Speeds on the third type are:

• 1800
• 2000
• 2200
• 2400
• 2600
• 2666
• 2800
• 3066
• 3200

Speeds on the fourth type are:

• 1500
• 1900
• 2000
• 2200
• 2500
• 2700
• 2800
• 3000

The fifth type is a 4GHz speed

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.
