I just bought a new motherboard for my old computer with a 450 mhz k6-2, and in the manual it has two voltage settings for the same chip, 2.2v and 2.4V. I wasn't sure witch was the correct one, and since it offered no other instruction, i went with 2.2 to be on the safe side. The PC works fine, but sometimes when a lot of programs are open, it freezes up for a few seconds, and goes very slow for about 30 more. Is this because the cpu is not getting enough power, or just that its an older system? Should i change it to 2.4? (by the way, i have 128MB of RAM, so i don't think thats the problem.

Seems to me (could be wrong) if you take your processor out and look at the soft white underbelly it'lll say what the voltage is.

2.4 volts wouldn't hurt it anyway, but if it's a 2.4 volt chip, it'll need it. If it's a 2.2 volt chip, then bump your multiplier up to 5 and it should run @ 500mhz at 2.4 or 2.5 volts.

Have fun and good luck.

if it's a retail chip with the heatsink fan attached to it look in the middle of the fan there is a sticker that will tell ya.

if it's a OEM your going to have to pop the heatsink and look at the top of the chip it will tell ya there. Running a 2.2 volt at 2.4 will not kill it but it will run hotter.

the main thing with the K6-2 chips is keeping them as cool as posible, becouse they run hot as is.

Get the best heat sink fan you can for that chip or add some cooling fans to your case to keep it happy http://sysopt.earthweb.com/forum/smile.gif

try to keep the chip temps below 50/c or just warm to the touch .

AMD has actually come out with two versions of the same chip, one at 2.4v and one at 2.2v. The only difference is the upwards tolerance to overclocking.The 2.2v version has proven itself to be a very overclockable chip, sometimes reaching above 550Mhz. The 2.4v version, however, kind of gives it to you in the shorts. I got stuck with one of the 2.4v models and I never got above 500Mhz for very long at all.
It all depends on yer mobo of course, so smilage may vary.

Thanks for the advice, turns out its a 2.4V. The most i've been able to overclock it on my old motheboard is 473. the new one is a Gigabyte GA-5AX. Is this board overclockable?

yes the ga5-ax is overclockable. all i ever got out of my 450 was an extra 50 mhz .i never upped the voltage though.

if it's a 2.4 volt K6-2-450 you can get them to 525 MHz but your going to have to up the voltage to 2.9 or higher

500Mhz is going to take 2.6 to 2.7 volts

and your going to have to COOL the **** out of it http://sysopt.earthweb.com/forum/frown.gif

just so ya know I ran that chip at 3.1 volts with a Alpha and YS-tech at 525MHz for months with out a problem at all

YOU are taking a big gamble with V-cores above 2.7 with any K6-2 chip though
