240 is pretty much common as dirt as far as Winchips go. the 233, 266 and 300 are rare.

Huh, 233 you say? Because if I have one other than the 180 that's in my iOpener, that what I thought I had somewhere (last seen 2 moves ago) .. I was underimpressed, a couple or three years prior I was kinda excited for them to "bring it" i.e. more competition, and the marketing speak made it sound like an actual contender. But as I recall, in a 430VX board and a 430FX board it was slower than Cyrix CPUs I had running at 166. Making it the upgrade chip that wasn't. I guess there's a theoretical socket 5 board, with barely the power margin to run 133 P54s that you could cobble it onto and feel like it was an upgrade, but socket 7 was in general way easier to find a faster chip for. So I guess mine didn't even get kept close to hand as "next best" or "I should find this a board of it's own", so I'll probably find it in a nest of
P75s and SX25s or something. ... I still woulda been interested to try out the faster 2Bs, but given a choice I'd probably take a 2.2V MII 366 or a MII 400 to play with over any winchips, even if they are supposedly more common.

The original Winchip, not the Winchip 2 came in at a max of 240Mhz.

Weird cyrix Cx486DX2-V50QP on a PGA160 board I found, no idea what it fits. Probably some laptop. Never seen one of these before, haha.

That is for sure a weird little CPU, you might be able to find out what socket it is via wikipedia.

Not sure it would be a lappy model, might be for a SFF kiosk type machine ala portable ATMs and information kiosks.

Just poking DuckDuckGo it seems PGA 160 is mostly used in Kiosk type boards and industrial/embedded applications, interesting little chip you have there, would be fun to find some parts and make a build from it, there is also PGA 140.

I'd go for the MIPS R8000 😀

nah, that was used in a pile of SGI systems in the 90s and is still commonly found, even if 98% of those systems have long since been sent to metal recyclers

The R8000 was a special CPU, it had amazing FP performance, and it's quite rare, only a few systems were released with it, most were R5000 or R10000 models...

I have this Cyrix MIIv in my collection, should be rare today?

I wouldn't consider that rare. I'd expect to pay no more than $15-20 for one.

This is crazy, an AMD K5 PR200, look at the price, reached after the auction: https://www.ebay.com/itm/125228128174

I have an K5 PR166, which runs completely stable with PR200 speed, also with reduced VCore (3,52V>3,3V) and have payed about ~30€ for this CPU. One of my favourite Socket 7 gold digger CPUs in my collection.

I was able to overclock a amd pr133 to “pr200” on a PCCHIPS m571 by using an unofficial 4.1 volt core.

Makes me think AMD should have offered the k5 as a socket 4 overdrive chip

There was a company that did just that. Good luck ever finding one though.

Is the withdrawn PIII-1.13 Coppermine rare, or did a lot of them stay out there in the wild?

Wait these are rare??? I bought a couple of them (SL5B2) off aliexpress for next to nothing in 2015!!! I have them in an MSI 694D Pro Dual that's been sitting around for the last couple of years, unused...

[EDIT] - it seems these CPUs had stability issues. This is interesting (at least to me). I'll take the two chips I own off the MSI 694D where they ran on winXP SP3 and test them individually. If even one is unstable I'll make a thread about my findings.

I'm finding a $5-10 USD Pentium III-S 1.4 Tualatin very very rare, if someone has one for sale shoot me a pm.. =o

On the day it ended, the exchange rate was such that the US price was $1337 😀

With a crazy Socket A cooler, like a Thermalright SP-97? I think the K5 gets very, very hot with this voltage.

The PIII 1.13 Coppermine that was unstable and subsequently called back by Intel per august 2000 was a Slot 1 CPU. Rumour has it that some 200 were issued and some 20 never made it back - very rare thus.
Your SL5B2 is an FCPGA Coppermine-T version that was issued somewhere in summer 2001 and that edition worked fine and is not extremely rare.

Cool, didn't know they were talking about a Slot 1 version.

My chips are regular coppermines, not the "coppermine-T". No IHS. https://www.cpu-world.com/sspec/SL/SL5B2.html

The coppermine T is the SL5QK: https://www.cpu-world.com/CPUs/Pentium-III/In … 33PZ006256.html They have an IHS installed like Tualatin chips.
