amd k62 450 3d mod 8 atx

amd k62 450/523 stable in all apps 450/550 not stable in gaming

welcome to the forums.

you might get it to run stable with good enough cooling and uping the Vcore a bit. whats you're specs?

yes indeed.. if temps allow, try 2.8vcore

these chips are not good gamers, lacking AGP mostly...
and 550 seems to be as high O/C as you can get with them..
but try your voltage, and good luck

Check the other K6-2, K6-3 threads posted within the last two days, they've got good info. There's a ton of info about those chips that accumulated over the summer. Make sure you've got several hours to read them. It takes a bit of work but you can improve your overclock dramatically. Check my signature.
