Does anybody have any information on overclocking K6II's on these motherboards? i am only looking to squeeze a bit more speed out of it without a real difference in running temperatures. Thanks

BUMP

Come on, somebody has to know. I've never overclocked a K6 before!

JD, I'm not to familar with that board, don't expect to much out of that K62 without extreme cooling, go here http://www.overclockers.com/ and then to the cpu database, you can choose different combo's, at least it will give you a idea on some aspect's of ocing that chip, you could also do a google search like, overclocking a K62 your proc. speed on a your mb. hope this helps. there's other sites that offer cpu data base's also, don't have all the links.

Thanx alot. I'll have tp try that.

OK, my question now is how do I change the core voltage and the multiplier? I'm sure the Athlon pencil trick doesn't work here!

JD,
Your right about the pencil trick, it won't work thats for the newer generation processors. Your going to need your mother board manual for the jumper locations and settings, ( READ THE MANUAL) if you don't have that go to Gigabytes site, go to support then look for the manuals section, then download the manual for your Mother board PCB revision. Note: the revision number should be somewhere on the mother board either a sticker or printed directly on the board. I'll try to keep it brief, There's different methods for overclocking, multiplier, core voltage, front side bus, I/O voltage or various combinations of the previuos mentioned. FSB (Front side bus) overclocking can be tedious some of your hardware may not be able to handle it, memory, video,sound cards etc. Overclocking is trial and error, Start out with uping the multiplier setting in the smallest increment possible, if everything boots up ok run some sort of program that test's the system for stability, ie. sisoft sandra, prime 95,etc. you may hit a wall right off the bat, windows protection error, you may have to up the core voltage & multiplier together, take small steps, use good cooling when uping the v-core voltage your generating more heat at the processor's core. Start simple the multiplier is a good starting point. A updated motherboard bios file may aid in higher overclock's, again there's alot of variations that can result in a successful overclock. I hope this helps you out, or atleast gets you started. Maybe someone will post with a more positive procedure or method.
Good luck

JD...

I've got a K6-11 500 and a GA-5AX sitting in the corner that I hardly use anymore. This is a Super 7 Mboard.

First let me say that the 5AX has a reputation for not being all that stable. Last summer I was banging around with it and and there wasn't a BIOS upgrade available.

The K6-11 CPU's don't handle much O/C. Usually about 50-75 Mhz is the limit. The K6-111, now that was a different story.

The Core Voltage for your chip, etc. is stamped right on top of the tin cover of the CPU.

All of the multiplier, Core Volt., FSB (Bus Speed) adjustments are made with jumpers on the Mboard.

Example: 500 CPU uses a Multiplier of 5, a Bus Speed of 100. C/V of 2.2.

What I do is set the FSB at 110 and run the chip at 550. I couldn't get the Multiplier setting of 5.5 and FSB of 100 to boot up for me. So I just stayed with 5 and 110.

The old K6's are fun to mess around with. Forgiving as hell.

Go to Gigabyte website (archive) and download yourself a manual. All the different settings for the different speed chips will be in there. Then just do the trial and error and see what you can get.

Tomshardware website still has some old articles in the archive section that are helpful with the O/C of the old K6. I think AMDzone still has a K6-11 Forum. Possibly Amdmb also.


Luck.

K6-2 CPU's can only be overclocked via FSB cause the multilplier is hardwired into the CPU.
You can pretty much forget about attempting to o/c your K6-2 if it's 400 or above in speed, 500 was the last AFAIK and that way at the upper limit of that CPU-core.
You could try it even then when you're an o/c enthusiast like others but you won't see a difference in real world usage.

Give as a few more details on mobo/CPU and eventually cooling (hsf/casefans).

DocSilly....I can assure you K6-2s are NOT locked...and 550 was the last.

As far as O/C, OldMan is right on, except I had good luck with stability using the F3 (last) BIOS. I've used the 500/5AX combo, could get 600/605 @ 2.8v(!) on a cold night, max reasonable o/c was 575/578 @ 2.7v. Personally I ran it at 4.5x120 for a long time. You'll find all the multiplier/voltage/FSB settings are silk-screened right on the mobo, too.
Good luck, I had lots of fun playing with my 5AX!

edit: oh yeah, and the adjustments are via DIP switch, like most Gigabyte boards, not jumpers.

JCIV, thx for the info, I really thought the K6-2 would have the same locked multiplier like the Intel ones.
http://www.examedia.nl/ocf/overclock-k6-2.html
And I found this statement "The original pentium cpu's are unlocked , Pent 1 MMX 133,166, 200, 233. As well as all AMD K6-2 and K6-3 cpu's."
You learn something new every day.

Hey it's cool. I'm just glad to find a post I really know something about!

BTW little error in that statement you found too, Pentium 133s only came in MMX flavor in mobile packaging
