Pentium OverDrive - Pentium Sockets

Pentium Sockets

The original Pentium chips ran at higher voltages than later models, with a slower 60 or 66 MHz front side bus speed (Socket 4, 5V). Although little known, Intel did in fact release an OverDrive chip for these sockets, that used an internal clock multiplier of 2, to change them to a "120/133" machine.

• PODP5V133: 133 MHz on 66 MHz bus or 120 MHz on 60 MHz bus

The OverDrive Processors for the Pentium 75, 90 and 100 were also released (Socket 5, 3.3V), running at 125, 150 and 166 MHz (clock multiplier of 2.5). The 125 is an oddity, because Intel never made a Pentium 125 as a stand-alone processor.

• PODP3V125: 125 MHz on 50 MHz bus
• PODP3V150: 150 MHz on 60 MHz bus
• PODP3V166: 166 MHz on 66 MHz bus

These were replaced by Pentium OverDrive MMX, which also upgraded the Pentium 120 - 200 MHz to the faster with MMX technology.

• BOXPODPMT66X200: up to 200 MHz on 66 MHz bus (clock multiplier of 3.0)
• BOXPODPMT66X166: up to 166 MHz on 66 MHz bus (clock multiplier of 2.5)
• PODPMT60X180: up to 180 MHz on 60 MHz bus (clock multiplier of 3.0)
• PODPMT60X150: up to 150 MHz on 60 MHz bus (clock multiplier of 2.5)
