Mine doesnt like more then 550mhz 🙁

It is a 450mhz K6-3+ on a Asus P5A

K6-3+ 6x100 reaches Celeron 300A@450MHz benchmark results.

I'm currently working on some S.7's, trying to fix some issues, I have a Soyo 5BT5, which has a missing cache chip pin, until I fix that I can't use the L2 cache.
The alternative would be to use, a CPU with integrated L2 cache, for example I would have a K6-2+ 400 1.6V, which could be installed, but the minimum jumper voltage is 2.2V.
These could be undocumented settings, which could give different voltages (from those reported in the manual), and could be found by measuring the voltage without the CPU.
In the image there is how to do it, personally I have never tried it, but it is possible that it works on any S.7 motherboard.
If I could get 2.0V or less, I could use the K6-2+ with FSB 66 or 75, and multi 6X, getting 400 or 450 MHz, I hope it works, but if there are problems, perhaps the BIOS would need to be modified to support that K6+ processor.

Competition rules:

-Must complete at least three passes 3dm2000, or one hour of super pi, no time evidence required, honor system. But do post screenshot of score alongside cpu-z showing clock freq.

Surely super pi is the better test, as it's more CPU intensive?

Sounds plausible.was figuring some around here might already have the 3dm2000 work done and could just post without much fuss. Tryin to accommodate. Basically, if they are sure it’s stable. Post it up!

Mine is currently clocked at 616mhz @ 112x5.5.
I'll have to fire it up and run the marks to see how stable it is. I can't recall the voltage, maybe 2.3v?
I will try to do some testing this week just to see, I have a feeling it won't be 100% stable and will only be at 6x100.

I recently seem to have discovered the source of my instability system bios cashable was turned on. Reminder to turn that off on k6-+

Kept having crashes at specific spots when installing linsux and random windows crashes. It seems it is stable 112x5.5 now!

Over many tests this was the highest speed my combination was able to achieve. I've seen people go higher than this, but after trying a number of both genuine K6-3+ chips and cache modified K6-2+ 570s, I've never been able to reliably go higher than this. I even recapped the board, but nope.

Wow.

Damn, I really need to get my TI500s working… I even have a Hercules purple one.. but can’t seem to get it to post and the gainward one doesn’t seem to want to work with the drivers.

Btw, I also am at 112x5.5

There were some guys around here binning k6-3+570 chips a while back (modded) and installing athalon heat spreaders on them with liquid metal. Would be cool to see what one of them came up with for a record.

Good to know, thank you. I will have to check that.
