...good motherboard with microchannel riser
486 slc2-75 i believe...

If it is an SLC2 it is 50MHz max (as the main CPU on the motherboard, if it were a CPU daughtercard upgrade from the 386SX-20 or 386SLC-20, it will run at 40MHz). The 486SLC3 version ran the CPU at 75MHz (with the same daughtercard contraints if upgrading a 386SX or 386SLC motherboard, a 3x multiplier of the motherboard CPU clock). I can break it down for the submodel encoding, but sometimes the systems were modified after factory without updating the stickers.

i powered it up and ran chkcpu... it is in fact a 50mhz...
