I have the chance to buy this CPU for a good price but the seller doesn't have a mainboard to test it, I don't have one either.
How reliable are these? I know it's impossible to tell but I know that socket 462 Athlons are very sensitive to cooling failures, one second without a cooler with an Athlon 462 and it's toast. What about the slot A variations? Are these reliably built like the slot 1 Intels?

Should be fine. The motherboards are harder to get working though....

Yes, probably won't get a board anytime soon.

If you damage these, something really went wrong. Struck by lightning, power surge, exploded power supply, extraordinary temperatures, et cetera...

The voltage/multiplier couldn't be set higher without a GFD, which required opening the CPU package.

Do you have some 50mm fans laying around? 😀
Oh and check if the L2 cache makes contact with the heatspreader. To my experience, the paste can be a bit misplaced. They should have used pads because of the 2mm space between.
Be careful when disassembling, it's quite challenging if you're planning to.

Nothing to test it with so that will have to wait.
But if you guys say that it's a reliable design then I'll buy it because it's my first slot A CPU. 😀

Congrats! Welcome to the club. Now on to fetch a nice board.

I'm working on a tormented Abit KA7; about 30 caps blown, missing heatsink, missing SMD capacitors, few bend pins IN the slot (for crying out loud)....

I haven't seen a slot A board on the local auction site since I started collecting hardware in 2019. It's like the socket 8 board for me. Plenty of Pentium Pros, zero boards. Well, I'm patient. 😀

Yeah hard to find. I have been lucky to have two although the first one died very quickly. The second one I think is an OEM compaq one but works well. The fan is very loud on the CPU, need to replace it.

So it's missing a fan I presume? Or were they sold with a heatsink only?

My only K7 Slot A (K7-600MTR51B-C) came without any heatsink or fan originally, uses same as a P2 H/S fan AFAIK. It looks just like a Pentium II without the heatsink+fan.
Have had it for years along with the Asus K7M board and still works using a P2-dual fan P2/slot A cooler.
Good luck finding a board but Asus, Abit and Gigabyte made some good ones...
On the socket 8: found a good board and included cpu+ram for ~$70 US back in June, is a DFI board. They do not come up often but sometimes get lucky 😀
Will keep my eye out for soc8 board for you.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

That's a pretty good price for a socket 8 board.
I curse the day I sold my Compaq Deskpro! I didn't really care for the Pentium Pro back then.
It's ironic because now I have 2 Pentium Pro cards for an IBM 704 but not the server itself. 😁

(not my images, I only have 1 of the cards populated)

That's very kind of you. Your board looks almost like one of my slot1 boards. I had to remove the green chipset heatsink because the CPU didn't fit in the socket with that on. 😁
