After having to pull out my book for my system and double checking. I have an Antec MB5897 and I already knew it supported K6-3 processors, but I wasn't sure if I could get voltage low enough for the K6-3+, and I got lucky the manual shows the ability to set the voltage down to 1.6 possibly lower. Anyone know the best voltage to run these at? Its going to be running at either @ 100x4.5 or x5, not planning on OCing it too much, this is for my father's system, replacing a AMD k6 200 system.
