Hi,

I have and handful of AMD K6-III+ CPUs that I need to test to make sure they work before I sink more time into a project to use them. The problem is I don't have a proper Super Socket 7 system available, let alone go down to 2.0v, and the last one I tried to purchase got sniped out from under me in an auction.

I'm located in Portland, OR and can make shipping super easy and simple via my FedEx account. I'm happy to also sort out how to make it worth your while for helping me out.

All I'm really looking to do is verify that the CPUs are operable. That's it.

Cheers!

I could test them, but if somebody is closer shipping should be a bit less.

The thing about the K6-2+ and K6-III+ CPUs is that even though they are rated at 2.0v, they are usually not completely stable without 2.1v

Also, a lot of SS7 boards don't listen voltages that low but the jumper settings will let them go down that low and is usually really easy to figure out what jumpers add what voltage by looking at the user manual.

I'm in nor cal and I'd be fine with doing it.

After watching many YouTube videos about older computer hardware, YouTube began recommending videos about trains - are they trying to tell me something?

True ! And the BIOS must identify it or else will not boot proper (like FIC VA-503+ must have bios that supports K6 + cpu's from my experience w/rev 1.1 and 1.2A).

I have a spare 503+ rev 1.2 that could test them but better, Nathan_A, you let one of the longer term members here do it even if I live close.

Actually it can without proper BIOS identification in my case, it will incorrectly identify it as a 486DX-66 CPU and would not enable any features related to the K6plus such write allocation on my Socket 7 Gigabyte motherboard.

The only thing is that one must disable both System and Video BIOS Cacheable for stability.

🤣 that sounds like it does not actually support it having to disable things ;p
But I get what you mean if all you want is too see if it works !
