HI

I have a 5240 that I would like to upgrade with a low power version of a
k6 III . Does anyone one know how to set the CPU voltage on this motherboard ?
I have not been able to find and jumpers with lables for CPU voltage.

thanks in advance,

mpm

No sticker inside the case? There should be one. JP3 sets the CPU core
voltage. It's located near the front of the board inbetween the CMOS battery
and the 15-pin connector for the Gameport, J23.

JP3 (CPU core voltage select)

VCC2H/L# low 2.0 2.1 2.2* 2.3± 2.4 2.5 2.6 2.7
VCC2H/L# high 2.8 2.9 3.0 3.1 3.2 3.3 3.4 3.5
pins 1-2 off on off on off on off on
pins 3-4 off off on on off off on on
pins 5-6 off off off off on on on on


The * indicates the factory setting for the preinstalled K6/2 450.
