Ocing K6-2's?

[Athlon4all]

I may be in the near future purchasing the very ocing friendly board Asus P5A. I'm am just wondering on a few things:

1. What's a good Super7 HSF?
2. What can I expect from ocing using this board with a solid HSF and a K6-2? K6-3? K6-2+? K6-3+?

Thanks

forget about it I have OC K6\2's in the past and it will just lockup and kick you back to windows like crazy
It's not because the heat it's just they plain out cant handle it if you want to overclock get a Celeron or Duron
I recommend the Duron they are very fast and ultra cheap

Thanks for the warning, but I still would like to try. Anyone?

i dont know.. it was very hard to oc my friends k6-2, 300 .. it would only do 333..

and it had huge heatsink too ...

good luck..

I have owned a k62-333 had it overclocked to 380 -any higher would lock had pretty good size heat sink and good thermal paste.
I have also owned a k62-500, would only go to 550 and then it would become unstable.
I think that anything over 550 is going to take some really good cooling.
in case you don't know you may want to lower the multiplyer to be able to increase bus speed, the higher you can get your bus speed the better.
my 550 (5*110) ran better than (6*100) becuase the l2 cache is not on chip and with the highter fsb you could access it faster.
so if you can't overclock always try lowering the multiplyer so you can raise fsb, you may end up with a slower rating,but overall speed will be better.
good luck

Dude, with Athlon and Duron prices so ridiculously cheap, why even bother? I don't know why you are buying an ancient K6 board when you can get an Athlon board for around $65.00. A 1.0 or greater T-bird will seem like greased lightning to you.

I do completely agree that if you're gonna buy a new setup, you can get a duron or tbird rig for pennies more and a whole order of magnitude more speed, but I suppose if you're really nostalgic, you might want a k6. Hell, I just bought one of the old cyrix m1 cpus just cause I felt like reliving happier days. jic tho

1. Think a socket 370 HSF will fit on a socket 7. A lot of socket A hsfs look like they'd fit too. I'd go with maybe an alpha pal6035 as you're not gonna be dissipatin a whole mess of heat and you should have a LOT of ceiling space with that thing. A volcano II would accomplish the same, but be cheaper and quieter.

2. Not much, but I've always been a fan of the k6 series. But they're just not designed to OC very well. I'd get a pc-pga celeron and an i815 or apollo 133a board if you didn't want to buy some of the OC boards for the socketA. The 65 dollar boards are virtually Overclocking-proof.

3. If you want to OC with a duron or a tbird, I(emphasis) would go with an iwill kk266+, an asus a7v133, or an abit kt7a as the kt133a chipset has had a bit of time to mature and it'll be easier to start up OCin. (This is for OC-ability, not necessarily performance)

Finally, I don't really like the concept of the kt266 as it reminds me way too much of the kt133. They slapped an "a" at the end of it and it becomes a great chipset. Hehe...maybe it's a conspiracy, only chipsets that get an "a" at the end are good. lol

Don't underestimate K6(2)

there is a Mis Conception that K6(2) are not OverClock Friendly!

I have 2 K(6)2: the very first 266mhz and the 300mhz.

My 266mhz can only be overclock to 333mhz, this is pretty much correct for all 1st. Gen K6(2)

However, I bought another AMD K6(2)300, and it has the critical CTX gold emblem on the serial #, indicates its the same CXT core in the K6(2) 400

I was able to OC to 415mhz (83mhz x ?), then I lapped it (sanding both the cpu and the heatsink), and I was able to get it stable at 450mhz!!!!

Apparantely that is nothing, I have heard that ALL the later K6(2) 400mhz - 550mhz can easily be overclock to 600mhz - beyond

the secret trick is to set the muliplier to X2 (in the CXT core, 2X multiplieri is remapped to 6X)

Hope that helps!

If you can still find a 2+ model at an acceptable price, those are notorious for overclocking well with just OK cooling. Especially the 450s -- these can get to 600 with Tornados.

Thank you I am just researching. See a Super7 mobo died on me recently, and it was fine performance wise, so i'd like to stay with it, but believe me if It ends up I can go with a Duron for the same price, I will take it. Does anybody know of HSF's for K6-**** series? If I get a new board I am going to have to buy a S7 HSF. Thanks

I worked with a few K6-2's and (naturally) tried overclocking every one of them. Most would only get to the next level, e.g., 300MHz --> 333MHz and remain stable. I did run across one outstanding K6-2/400 that has been running stable at 500MHz for nearly a year now.

 

[SilverThief]

I had limited luck with my K62-350, got it to 400 stable but no higher.

 

[NelsonMuntz]

In my experience I could get a K-62 from 400 MHz to 500 MHz without much effort, and I can get a K6-3+ from 450 MHz to almost 600 MHz stable without too much trouble as well. There are a lot of HSF units available that will fit socket 7. Check here for a listing of some of them. They actually have Socket 7 and Socket 370 on the same page and it has been my experience that if it will work on one it will work on the other. I actually have an Alpha Pep66T on my Super 7 right now and it cools great!

I have a k6-2 350 in my webserver (plug - http://www.beerpalace.org).

It's running at 460 (115*4) no problem. Running linux, and dnetc OGR (100% CPU usage).

I've had it up to 540 (120*4.5) at 3.2 volts, which is very very high, and hot.

As for CPU coolers, just about anything will work. You could probably put a FOP-38 or WBK-38 on it if you really wanted to..

Also, I took the Metal cover of the top of my chip using a razor blade.. there is a bit of glue near each of the four corners.. seemed to make a little bit of difference, but required quite a bit of work, and i dont know what the chances are of damaging the chip.
