So, like, does the K6 3+ 550mhz really exist?

Or are the few mentions of the internet purely fictions. I think I'd have an easier time finding an actual unicorn.

A fixer of things. I also broke those things.

Also unicorns are not that hard to find, or atlest the old fat ones aren't. a lot of people call them rhinos 🤣

What most of us do is get the low voltage version of the 400 and overclock it. I believe it's an embedded version, rated at 1.6V. These should be readily available.

Of course they don't exist. They're pure fiction, the figment of someone's sick imagination. Never believe they are real, not even for one bit.

Don't worry my tiny one, I will never think of selling you in a million years. There, there, calm down and go back to your motherboard.

Depends where you look. For me they were also very hard to find but i managed to find a k6-3+ and 2x k6-2+ locally trough the years.

On ebay they are easy to find, just overclock to 550-600mhz at around 2.1v and be done. k6-3+ :

There was a seller who a few months ago had a couple dozens K6-2+/570ACZ chips (the highest clocked chip ever made for socket7), got one of them at a very decent price.

There's one for sale even now, but the price is quite high: http://www.ebay.com/itm/AMD-K6-2-570-ACZ-NOS- … ygAAOSwhOVXfl4i

Here is a photo of a K6-III+ 550.
http://www.chipdb.org/img-amd-amd-k6-3plus-550acr-375.htm

For the K6+ series, I have only the K6-III+/450ACZ 2.0V, K6-III+/400ATZ 1.6V, and K6-II+/550ACZ 2.0V. There have been some III+ 500 and 550's for sale, but the seller wanted more than $100.

For harder to find K6-III chips, I do have an AMD K6-III/450AFX 2.2V. This was the lower voltage version of the non-plus chips, that is, as opposed to the K6-III/450AHX 2.4V chip.

For non-plus chips, there was also an AMD K6-III/475ACK 2.0V.

Was the latest the same core of the K63 or the core of the K6-3+ with the cache disabled? How can it works at 2.0v?

I am not sure. Perhaps an extraordinary cherry pick of the K6-III-450 series, or one of their last production runs with superior wafers and all the production issues worked out?

Well, considering how hot the original K6-3 400 ran in my tests at 2,4v to be stable... well.. some really lucky production I'd say. 😁
Probably I'd say that it was the + core version.

Ive tried a few times but anything over 2v just doesnt post. Wouldnt be surprised if I'm doing something wrong though, I didnt start learning how to OC until the lga775 days.
