Hi all I have a few socket 7 motherboards laying around that have Pentium MMX 200 in them
This is a little to fast for my liking and want to know if I can fit a 75mhz Pentium Cpu in them? I'm not sure what Cpu types will work with socket 7 the slower the better thanks

Note that you can slow down a Pentium MMX using SetMul. Toggling the various test registers as well as L1 and L2 caches can give that CPU quite a bit of range.

Check out this video by Phil for more details.

PC#1: Pentium MMX 166 / Soyo SY-5BT / S3 Trio64V+ / Voodoo1 / YMF719 / AWE64 Gold / SC-155
PC#2: AthlonXP 2100+ / ECS K7VTA3 / Voodoo3 / Audigy2 / Vortex2
PC#3: Athlon64 3400+ / Asus K8V-MX / 5900XT / Audigy2
PC#4: i5-3570K / MSI Z77A-G43 / GTX 970 / X-Fi

You can use a 75MHz Pentium on all boards that can set a 1.5x multi and 50MHz FSB.

Generally it shouldn't be any problem. However you have to check for each board anyway as you need to set the jumpers accordingly (voltage, etc).

Phil also has the charts on his site which might be easier to access when comparing setting rather than scrubbing through the video.
