==Pentium sockets== {{Multiple image |total_width=350 |perrow=2 | image1 = KL Intel Pentium Overdrive Socket4 b.jpg | caption1 = Pentium Overdrive for Socket 4 without fan | image2 = KL Intel Pentium Overdrive Socket4 a.jpg| | caption2 = Pentium Overdrive for [[Socket 4]], 120/133 MHz. | image3 = KL Intel Pentium MMX Overdrive B.jpg | caption3 = Pentium Overdrive MMX without fan. | image4 = KL Intel Pentium MMX Overdrive A.jpg | caption4 = Pentium Overdrive MMX, 166 MHz. }} The original [[Socket 4]] Pentium chips ran at higher voltages (5V) than later models. 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. *PODP5V120: 120 MHz on 60 MHz bus *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]], 3.3 V), 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 version with [[MMX (instruction set)|MMX]] technology. *PODPMT60X150: up to 150 MHz on 60 MHz bus (clock multiplier of 2.5) *PODPMT66X166: 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) *PODPMT66X200: up to 200 MHz on 66 MHz bus (clock multiplier of 3.0) {{Clear}}
