I have some 486 ISA slot motherboards that only support 5volt CPU’s up to 486dx-50.
Can I use this Intel Over drive CPU ?

IIRC the ODPR chips were for 5V board in any case (the OPR and PODP chips for 3V).
Since the ODPR66 runs at 33x2, I would think that should work and won't get fried in testing (unless you clock it at 2x50, maybe).
If you look the part number up on CPU world it says 5V.
*Too* *many* *things*!
those stock heatsinks are total crap I was testing a 5v board with the same overdrive cpu 66mhz and decided to play duke nukem in svga mode which was smashing the cpu and frame rate the system crashed after about 10 minutes and the cpu nearly burned my finger, about 10 degrees Celsius winter at night too
However I clocked it at 2 x 40fsb =80mhz and it ran very nicely with a socket 370 heatsink on top of the stock one
Looks like it is ok according to wikipedia https://en.wikipedia.org/wiki/Intel_80486_OverDrive Altough it offers nothing special over a standard 486dx2/66 cpu. You can also get Kingston 586 upgrade cpus.
There's a glitch in the matrix.

Apparently 32-bit is dead and nobody likes P4s.
Of course, as always, I'm open to correction...😉
what i forgot to add is, if your running a dx50 on this board and by the looks of it there is a timing crystal it means most likely it will be running at 25 fsb or 50fsb only if you want to run 33fsb u need a 66mhz crysyal then divide it by 2 on the jumpers to get 33fsb
the overdrive will work at 50 fsb under clocked
