I really neeed to know my games are running way 2 slow and i have all the other upgrades. SOME! PLZ HELP ME
u can either up the fsb or multiplier to get a higher speed. normaly u can do that either in the bios or on the motherboard itself with jumpers. what motherboard do u have?
Give us a rundown on your specific parts. What motherboard is it (brand and model)? What FSB options are listed in the manual? What's your current FSB and multiplier setting? What are your core and i/o voltages? What heatsink/fan setup do you have? Does your board have temp sensors built in? If so what are your current temp readings?
That'll help us help you alot. :)
Btw: Welcome!
Welcome to the Forums!
I have a K62-450, and had a couple of others-
These cpus don't overclock very well, BUT if your mobo has jumpers/ dip switches you should be able to get a bit out of it:
My mobo(s) only had multiplier and voltage adjustments, nothing for FSB.
I had a best oc of 550mhz-stable with 1 chip, may it rest in peace!
The others only went to 500 stable for any period of time.
But one note: I've heard people talk about removing the heat spreader and mounting a decent hsf to the chip and getting better results. I have pulled the spreader off of my last K6 but not built it yet, maybe tomorrow.
In any case: get the jumper/dip switch settings for the board and try the next speed up, test it out; repeat until it crashes or you run out of settings! You may want to increase volts to the chip as well, but be cautious here, it kills the chip a lot faster with the k6s.
Upgrading from a K6 will be a few bucks- cpu/mobo/ram, but will be well worth it if you are having a hard time with the games; and like I said, about the best oc I've heard of for a K6 was in the area of 100/150 mhz, so even if you get lucky it may not help much! Good Luck ,man!

Been there, done that. :) Told FRANK how to be there, killed his chip. :( I no longer recommend this procedure to anyone. It's not that it can't help but it's a delicate procedure. Lapping the top of the heat plate is a good idea though. I've heard that they have nickle over the aluminum so lapping will smooth the surface out and remove the nickle (which is an inferior heat dissipater).
Hey rog, nice avatar. New isn't it? Don't think I've seen it before.
Good point on the danger of removing the spreader from the K6- I got lucky though and it came off fairly easy. Posted the pc to check it, but.......!
I'd say the old saw about "this man is a trained professional..." but......HAH! I'm just a none too bright hardware geek!
Be warned, though Eobard is right: the spreaders are not known for ease of removal!
----Avatar new last night: thought I'd give both equal time since out of 5 pc's running, 3 are AMD, 2 are Intel: 3 AMD procs, 4 Intel!
UberPhluBB does good work, eh?

I am a real Newbie on this........How can i find out my fsb speed and this vold speed.........??? I spent alot of money upgrading everything 2 top of the line but the processor...
Is their any way to turn up the bus speed without taking yr machine apart??
With the mobos I had, no: your mileage may differ!
Most important thing you really need to figure out just what you can do is a motherboard manual. If you don't have one, but know what the mobo is, get it online.
You MAY have options in bios, but none of the old boards I worked on did:(
See what you can dig up: if you have nothing else, sometimes the boards have their name and model # on them, as well as having tables for jumpers, etc.
Just thought I'd post a heat spreader removal update:
Removal went fine, applied AS2 and an oem-type TBird hsf and began installing linux......halfway through, the install went screwy!
Missed one thing: after removal of the spreader the chip is a LOT shorter- not enough contact between core and heatsink= 1 dead K6-2!
It was an old friend and will be missed!:(
Too bad too: chip was running fine! Gotta get me another now;)
