Recently I found a strange looking Pentium 200MMX.

1. First, the SSPEC seems incorrect. SL27S is the SSPEC code of a 233mhz.

2. Second the manufacture week is wrong. Week 85 1997 does not exist.

3. Also, when looking more closely, it also seems that the backside has been "stripped off" and glued back together somehow, it looks really messy compared to an other pentium 200mmx I have. In the upper left corner a red "87" or something is written.

Any ideas if its really a fake, or just a Intel remarked 233 SL27S? If its fake, what chip is it? Pentium 166mmx seems the only option I guess, as the remarking of a 233mhz chip to a 200mhz chip does not seem right Laughing

Print is very rough and definitely not genuine.
IMO 166->200 relabelled, fakers put very wrong sspec in it Very Happy

Fake, judging from the poor printing I think that they just use paint to hide the original mark, and mark the new data on top of it.

Intel genuine units always marked with clear and complete letters, this one is not (the top of letter 's' is chopped)

Going through my trade chips the other day I found 2 potentially fake Pentium 200MMX chips.
Both of them are marked as SL25N, which is apparently a PPGA sspec, not a ceramic one. I'd say both are remarked up from 166.
