alt Hacker NewsI indeed remember too the family of K6 chips and their Super Socket 7 motherboards. They were cheap and affordable, and allowed cpu upgrades to classical Socket 7 motherboards.
The peak of the Super Socket 7 performance CPUs was reached when AMD released the + versions of those chips, the K6-2+ and K6-3+. Those were initially designed for laptops with lower powerconsumption and some enhanced instruction set. But they quickly became common in typical overclockers setup.
I got myself a K6-3+ that I was able to overclock to around 600MHz, probably on an ASUS motherboard.
Back then AMD was fighting so much to get marketshare that you could order for free all types of merchandising from AMD like posters, stickers and CPU badges, and they would even ship it for free from US to Europe. I remember always bringing some to hacker meetings.
I happen to have one of those 600MHz chips on my bench currently! It's a K6-2+ that has had the remaining 128KB cache unlocked, making it a K6-3+. It is indeed a speedy chip, performing somewhere above a Pentium II-450 according to Speedsys.
Do you recall how long you used the platform or your next upgrade choice? :)
