550... 570 with effort... 600 not likely

[akaBruno]

What kind of board have you got and what are you cooling it with? And what is your core voltage presently set at, multiplier, and what are your possible fsb settings?

I'd like to see if this sucker will OC. Never say never...

I'd say 600-616mhz is reasonable - if ya pump up the v-core a bit http://sysopt.earthweb.com/forum/wink.gif

Alpha is right, with proper cooling 600 and 616 is possible.

I don't know guys, about over the 600??!!!

I mean, just look at previous k6-2's.

The 450 2.2V, got it to 575 with aircooling.
The 500 2.2V, can get to 600.
The 550 2.3V, still around 600.

Looks to me as if around 600 is the limit for the present k6-2's.
Maybe the 0.18Micron k6-2's will do better.

What I've noticed w/ most K6-2's is that (depending on the chip of course), a 100mhz increase is a real push for it, but even more is possible w/ extreme cooling. It's all about voltage and cooling. It doesn't seem to matter if it's a 400 or a 500 etc. It still all boils down to an individual chip thing, some do some don't.
The only thing stopping me from breaking the 600 barrier is my TYAN mobo's 100mhz fsb.
BTW Jerry, If you set the multiplier to 2x it will = 6x and w/ a small increase in voltage 600 should be easily attainable. The only other way is to increase the fsb , if your board allows it.

I think it is only 5% or so that successfully overclock to 600 with a K6-2, there I think also it depends as much on your motherboard as cooling and voltage. Some motherboards seem to have less noise and therefore overclock much easier.

I would tend to agreee with the person who said that you are not likely to achieve much of anything above 600 with the current K6-2s - I wanted my first reply to reflect that so that you would not get your hopes up too high for this 550 chip - frankly, I'm amazed (and pleased) that the K6-2 has made it this far.

Currently (in addition to other systems) I am the proud owner of (4) K6-2 CPU based systems: (2) 400s, a 450, and a 500 - I'm no stranger to clocking these things.

got 550 chip installed settings are 100*6 on a ga 5smm mobo seemstable but dont realy know yet i had it to 624 and 616 but had errors in windows i dont think my ram could handle it any ideas how to set up bios so it could handle it better thanks guys all your info was great

I have a water cooled amd k6-2 450 2.4v cpu, and I have found that if I have to go above 2.7v, the cpu temp is very hard to keep cool. The sensor on the top of my cpu says 65f and the underside is about 110f when I overclock +100Mhz, because I need 2.8v for my 450 to run 5.5x100fsb @ 550.

So remember, the water cooler can only cool the top of a SS7 cpu, this does help some, but the bottom of that cpu is still going to get quite hot at extreme voltages.

I have a K6 2 400MHZ 2.2 volt that I've overclocked to 500 MHZ 2.4 volt. Had to install a extra heavy air cooler which keeps the temp around 108 - 115 F. So far no problems. I agree that overclocking AMD K6 2 above 600 MHZ is more than pushing the CPU.
It's asking for trouble. With 10 years experince on AMD K5 and K6, I offer this advise... Overclocking 50MHZ is no problem.
100MHZ overclocking requires higher voltage and heavy coolers. I would not overclock more than 100MHZ. Each chip when made is made to the highest CPU rating for that style of chip. I.E. a AMD K6 2 400MHZ was made orginally as a AMD K6 2 500MHZ, but when AMD tested the chip it only ran stable at 400MHZ so AMD stamped that chip as a 400MHZ. This is one of the reasons that some chips can overclock higher than others.
Also your motherboard is a factor in overclocking and proper support for the overclocking. Again, back to the 600MHZ "barrier" currently AMD is not offering a AMD K6 2 with a speed greater than 550MHZ. So 600 maybe 650 is pushing the envolpe on a 550MHZ cpu. I will go out a buy a 550MHZ cpu today and start testing.
I will post results using this new chip at various speeds and different motherboards.
I have 6 computers at home so I can do extensive testing. Stand by...!!!

Rick -
Try to use a mobo that allows the I/O voltage to be increased. I have seen many people get that little extra Mhz from a slight increase.

Don't try this if you are not aware that your 550 could die trying this, and without ever reaching 600.

....and yes, two "well done" cpu's from too much overclocking....been on the same little K6-2 450 overclocked to 5.5x95fsb @ 524 with 2.7v for six months, then up to 5.5x100fsb @ 550 with 2.7v for a month.

The water cooling is the safest way to do a good HARD "burn-in" and not ruin the cpu with the heat from the high voltage :-)

i have two 550's and have tried em on many a mobo, the only stable setting I ever overclacked it to was 575 (5.5x 105) most benchmarks reported it at 581 though...I'm begining to belive that a 550 is a 500 and they just happens to call it 550 with the voltage at 2.3 instead of the normal 2.2....interesting no?

last reply on this post is my k62 550@615, it can be done.

Am pleased to say have a duron700 @1Ghz now, life is sweet http://sysopt.earthweb.com/forum/smile.gif

I don't think that there is anyone that can push a 550 to 600 without frying it. It took 2.8v for it just to post and wasn't stable, failed protection error upon boot up in windows. 570-582 is the most you can get out of it upping the core to 2.4v

[Variable]

I think it is possible but:
the cooling will probably cost as much as a new CPU.(It's still fun).
With a K6-2+ it is possible and probably not as hard.
My 533 K6-2 is now at 582MHz and that on only 2.4/2.3V.
To go above that you will need 2.7/2.8V at least maybe with a watercooled peltier you could push the V down to 2.5-2.6V?
