RE:SW3...SW4....Correct Setting? posted by: Linuxguru, As mentioned by Turbo3,
Vcore (CPU core voltage) is set by SW4 on a V5. For reference, the settings are:
.2. .1. Vcore
--- --- -----
off off 2.0 V
off .on 2.2 V
.on off 2.6 V
.on .on 2.8 V
As always, the engineers at Quanta have shown an outstanding consistency in connecting the lsb to the low-order index of the switch position.
Using the the default FSB and PCI clock settings (66/33), the default multiplier (3x) and Vcore at 2.2v, the AMD-K6-III/333AFK (underclocked to 200 Mhz) is a drop-in upgrade that handily outperforms anything else for this socket. No fan required, either, so it's as quiet as the stock IO.
