Ok, so sometime ago I got an Athlon 700 slot A "classic" (I mean, non-thunderbird) and created a record for it in my database (just a crappy excel sheet btw) acording to the writings on the top of the plastic case.
Today I was finally able to test it and check it with cpu-z and other tools and found something quite interesting:
There are 3 types of Athlon 700 in Slot A format:
"Argon" core (Model 1 aka "K7", 250nm), part number AMD-K7700MTR51B C
"Pluto" core (Model 2 aka "K75", 180nm), part number AMD-K7700MTR51B A
"Thunderbird" core (Model 4, 180nm), part number AMD-A0700MPR24B A
Now here comes the tricky part, mine says AMD-K7700MTR51B A on the top of the plastic case, which would mean it's a Pluto/K75 core, but as soon as I powered it on and checked it, it appears to be an Argon core (and it sure gets hot as hell). I'm pretty sure the case has not been replaced, it's the original one. May it be from the time they were transitioning from K7 to K75 and somehow misprinted it or some plastic cases got mixed up?
I've checked the dates and the K75 was introduced on November 99, and this cpu has a date code of January 00.
PS: I registered to cpu-world forum to ask this question (same username as here), but I never got the activation email so I can't login. If anyone has an account there and can contact a mod or admin and tell them to re-send the email or just activate my account, that would be awesome.
