Cyrix 5x86-100GP 100 Mhz 486 / 586 Socket 2 / 3 CPU

This CPU is an Cyrix 5x86-100GP 100 Mhz CPU and is the perfect choice for a DOS / Win95 retro gaming PC

It is in good condition and was tested with some DOS games like DOOM2 and Monkey Island (tm)

In addition to that some games take advantage of the branch prediction features of the CPU, if you enable them. 

 

These CPUs run well at 120 or even 133 Mhz, if everything else is right. With "right" I mean to put the CPU into a "happy place" combination of CPU, mainboard, RAM and BIOS settings. 


It runs on 5 volt and 3.3 volt mainboards, however, since this CPU requires 3.3V you need (or at least should use) an adapter if you use it on a 5V mainboard.
