If you finally noticed that your cpu is slow and you want to overclock, I would personally suggest getting a new system :)

tough search... amd cpus...

if u can volt it up and cool it off u might get to 400mhz... real hot cpu in the days when u had to build your own oc'ing hsf's if u wanted anything good... chances are that the mobo u have it in won't let u do anything with it... these chips came in way lowbuck rigs...

IIRC, the 333 ran at 5*66MHz. Those CPU's ran HOT and didn't have a whole lot of headroom.

If you were interested in one of the K6-2/500, NewEgg has them for $18 with free shipping here.

I bought one for a machine that had a K6-2/300 and it went without a hitch and was a nice upgrade since it allowed me to also go from 66-> 100 MHz FSB. I use it as "testing" box for versions of Linux and such.

Should be 5x66. The few I've had in the past were dogs, topping out at 350 IIRC on a VA503+ mobo. Overclocking this is more than likely going to be done with jumpers for everything (voltage, multi, fsb, etc). There will be no modern conveniences and often times no written literature about the mobo other than silkscreening.

Good luck, it'll make you appreciate the modern BIOS.

Not to be a TC'er, but unless you're bored this project isn't worth it. It is very worth it if you are doing it for fun or to learn, but not for the performance you'll gain. It can be internet only @ stock and won't perform noticeably better with an oc. My advice is to make sure that you support it with as much ram as your board can handle and a decent HDD so that the CPU is never waiting for other stuff. Mine is really slow, but it is waiting for the 3.2GB Quantum to access the swap most of the time with my 64 MB of ram. Oh well, SETI still turns in a WU every other day so that's worth it.

the whole poitn was to ge tmmore outta the system i know it wouldnt be much bt whatever..... i doubt its gonna happen cause as many said and i have read... "it runs hot" so yeah... and plus i need to change the shitt with jumpers....

As I (fondly) recall, the K6-2 runs a FSB of 100 and multiplier of 3 (I remember because it blew away 66Mhz Pentium IIs of the time). However, most boards of that era required you to use jumpers or switches to set the FSB and multiplier, so find the manual for your mobo and grab a flashlight and pair of pliers if you want to overclock (3.5 multi at 100fsb should be do-able at least).

Sheesh. All you people whining about how "jumpers are too hard" make me feel downright ancient. What happened to Back In The Day, where you modded the P100 -> P120 by growing a pair of big brass balls and breaking a pin off your chip? :p

While a K6-2 "could" run at 100MHz, his 333 isn't spec'd for it. I would agree though, that if his mobo supports it that 3.5* 100 would be the best he could hope for. Even 75 * 4.5 (338MHz) would be better than what the spec is for that chip.

I don't necessarily agree.. it depends on what he wants to do with it. And for a total of $18 to be able to get a 50% increase in CPU power isn't a bad deal if he's actually going to use the box for something. There are lots of uses for old machines like that... testbeds (as I pointed out), smoothwall box, internal web/mail/ftp server, MP3 repository, home file server.... Granted, I wouldn't put much into such an old box, but a little money could make a nice difference.

HOLY MOLY!
M4H and I agree on something! Someone mark the calendar!

Of course that breaking the pin off stuff is for youngsters.... my first overclock involved having to desolder and remove clock crystals from the mobo and testing new ones to see what would work and then soldering in the final one for a MASSIVE overclock from 4.77 -> 7 Mhz!

With all due respect, a 50% percent increase on next to nothing is still next to nothing. It's fine if he wants to spend $18 and get that new CPU, that's cool with me. He was asking about OC'ing originally and that may get him a 10-20% increase in performance-that would be a decent OC. But if that OC speeds up a fictional task that normally takes a minute with a K6-2 and 10 seconds with a modern CPU, 48-54 seconds will still be slow. I'm not advocating throwing it out or not trying---far from it---. I am simply stating that those CPU's cannot be relied on for anything demanding either @ 333 or 500.

Aw, c'mon. You gotta give me a little credit - I was probably 7 when I did the Pentium mod. :D

Jeez, what a bunch of negative nellies :|

Let's see:

Q: I was just wondering if anyone knows the fsb/multi of these (stock) cause cpu-z doesn't show anything..... and i would like to o/c it.

A: Sure, they ran at 66MHz bus, 5x multiplier. If your mobo supports a 100MHz FSB, you may be able to run it at 3.5x100, or at least 5.5x66. You could also grab a K6-2/500, as mentioned, for cheap, and you could run that at 550 easy.



Now if the OP's question had been:

Q: Is it worth it to overclock my K6-2/333?

A: Just for the fun of doing it, sure. Will it get you anywhere near the performance of a newer CPU/mobo, no. Or, HELL NO! :)

BUT THAT WASN'T HIS QUESTION, WAS IT?

Sheesh.

7!!!

Ok... you officially got props on that one!
