Check the full code on the chip, it is likely rated with a high case temperature and lower wattage.
Should go 400mhz without touching the voltage 450 or even 500 if you crank it up to 2.4/2.5 volts but would need to test it, some mobile k6-2 (not 2+) go straight to 500mhz without touching voltage, others despite the very low voltage (1.6/1.8v) only go to 400 and voltage doesn’t much matter.

Seems to be 2.2V to me.

Case temperature is 80°C

This page I like for this https://www.cpu-world.com/info/id/AMD-K6-identification.html

Odd never realized that the k6-2 366 was only released and sold late after the 400 had been out 6+ months (366AFR is somewhat rare compared to the laptop version)

I will need to dig, I’m not sure if I unloaded all the low voltage laptop chips but if found could provide an example of what is printed on the top.

If memory serves most were ANZ which is 85C rated

Desktop chips were never rated at 80C+
So maybe not much visual difference?

I have a mvp3 board and it has a tonne of stability problems dono if it’s typical or something wrong with mine but at the very least the memory controller is horrible.

My friends all had MVP3’s because performance but good lord were those a pain to set up.

My roommate spent days trying to install an Ethernet card, he had to reinstall Windows then alter the order he installed components and drivers to finally get it to work. He also had to use a different version of the chipset drivers
PITA if there ever was one.

I had an MVP3 I bought to sell off some extra parts with and likewise I couldn’t get the Intel Ethernet card to work, once I finally did the system would crash all the time and I gave up.

I don't know, I have 1 MVP3 and 1 MVP4 motherboard, and aside from the MVP3 one not having enough juice for AGP cards beyond 1998 or thereabouts they are perfectly stable.

I may have skipped over them at the price listed not realizing it was for LOTS OF THREE. IDK whether to get 3 or 6 now 🤣

🤣... reading sure helps, I have not noticed that either until now so held off from buying any, thanks.

Mine was perfectly stable until I installed an Ethernet card, I tried multiple different brands and either it wouldn’t install drivers or was unstable.

Odd part was the cards worked great in other systems.

Don’t remember the brand anymore but might have been a bad brand

Did you ever try the VIA PCI Latency patch?

MVP3 are usually good for quite a bit.

I wanna get to the bottom of the table here...

But what about the two unmarked options: all 1-2 and then JP8 set to 2-3?

18 years later I would guess probably not?

I do remember that in the late '98 to 2001 timeframe that 550Mhz parts of either K6-2 or K6-3 were really hard to get hold of, most of the time stores only seemed to have 450Mhz in stock. I mean you can call me a liar by bringing up archive.org pages to prove web stores listed them for sale, or google books saved magazine ads, but if you were to actually attempt an order, most of the time you would be unlucky.

I remember the same.

What is the pci latency patch? A driver? A utility? Bios update? Hardware mod?

It's a Win9X "driver". Pretty sure it's just a small VXD that checks what chipset you are using, and writes values into memory to overwrite BIOS settings to fix a PCI bug in many VIA chipsets.

You know, circling back to those K6-2+ 570 chips, it's really got me thinking. Allegedly ~20,000 lots of 3 are listed on ebay, which is ~60,000 CPUs total. Do you think there are even that many Super Socket 7 boards extant which could use them?

hard to say, most of them have been trashed by now. But there will be many ins private collections for a long time
