K6 2+ 500MHz

[MadEye2]

The motherboard it's on has clock multipliers but doesn't have anything relating to FSB. On it's default speed it ran well enough but was always about 60 degrees celcius, but all the IDE cables and dust in it probably didn't help things - it's cleaned up now. Reckon it can be clocked up?

sure! I've done it, but you probably won't get much out of it. Might hit 550mhz. That was with a board that I could change the fsb on, not the multipliers. It's been a few years though...

I don't think I can do it then. It's on a 5 multiplier already and the next is 6. Maybe if I put it in a fridge and boot it up.

I don't know if I can help much, but since I have been working on my K-6-2 350 today I am at least a little warmed up on the subject 🙂

I think the fastest stock speeds where either 500 or 550 MHz so you are near the max stock speed. the only thing you will be able to do is up the multiplier to 5.5 (this is the highest multiplier) or raise the FSB.

The standard K-6-2 got the most benifit from a faster FSB but the K-6-III and K-6-2+ (or 3+) could benifit either way due to the integrated L2 cache.

The multiplier should be controled by either jumpers or a small set of switches on the motherboard, the FSB could be controlled the same way or in the BIOS (sometimes both).

If I remember correctly somewhere between 600 and 650 MHz was where most K-6-2+ owners stopped due to memory errors or hard drive failures at bus speeds any higher.

I can't remember what the common temps where for the K-6-2+ processors but 60C sounds a little high to me, you might want to verify that the voltage is set right (I think they ran at 1.6v or it might have been 1.8 not sure).

I hope this was a little help at least 🙂 good luck

you can also use a different hsf. any hsf that works with socket a should work fine with socket 7.

I don't think overclocking a K6-2 500MHz is worth it IMO. Last time I used a 350MHz K6-2 and then I switched it to a 500MHz one and the performance difference is so little that it can be considered negligible. (that is with PC100 SDRAM BTW)

Anyway feel free to try OCing that thing but don't expect a significant jump in speed if you do it.

The K62+ core is a Mobile core. The slower rated K62+ 450 could run all day at 577 Mhz. My 550 used to run at 100 x 6 all day long. I removed the heat spreader for better temps though. It fell flat at around 660 mhz though, no matter how hard I pushed it. Some people have reached the 700 Mhz region with theirs, but don't expect much more than 650 mhz without extreme measures. At 600 Mhz, the K62+ is equivalent to a Pentium III 733 for most comparisons.

There's a program called setk6 that gave me a slight increase in speed - with it I managed to get ZSNES to run at 60fps on some games where as before they only topped at 55fps. Not significant I know but hthe games did scroll smoothly.
There doesn't seem to be any FSB jumpers or switches on this board, or the bios for that matter - though it needs flashing, but there are switches for the clock multiplier but there doesn't seem to be 5.5 setting.

I might try setting it at 600MHz for the hell of it, it's not as though I use it now and I won't get much if I sell it. I might buy a cheap socket 7 P3 chip as this K6 2 500 only gives me the same performance of a pentium 2 300

there are no socket 7 p3 chips. they are all slot 1 or socket 370.

My sister is still running that computer. We are running a Via- 503A. I upped the voltage by i think .02 volts and that sucker OCed all the way to 600 before her crapy stock cooling ran out. Also she has no case fans and the case is in a *gasp* desk, so you can imagine my suprise at making it that far. SO it runs stable right now at 550, only because i dont want to give up one of my Panaflos.

I meant K3.
