Hello all, I'm hoping someone here has the answers to the question that intel themselves could'nt answer. I bought 9 x new 233mmx cpu's on ebay which turned up today & the first thing i noticed is the stepping + running voltage were odd to say the least. SL2Z3/1.9v. I cannot even find a reference to it on google. Thanks. make it idiot proof & somebody will make a better idiot.!

The desktop version of the 233MMX runs at 2.8v, the mobile version runs at 1.9v...are you sure about that spec number?

Yes i'm positvely sure about the spec number,i'm holding it in my hand & triple checking it as i post . FV80503233 S L 2 Z 3 / 1.9v . Iv'e typed it a dozen times already on different forums & sights make it idiot proof & somebody will make a better idiot.!

Well, the FV80503233 number is definitely for a 233MMX, but the 1.9v means it's a mobile CPU. I can't find anything for the SL2Z3 number either http://www.cpu-world.com/sspec/Pentium.html

I emailed intel about it & this was their reply. Hello Ken, Thank you for contacting the Intel(R) Museum. For references to the Intel(R) Pentium Processor with MMX(TM) Technology documentation, please refer to: http://www.intel.com/design/archives/Processors/mmx/ . I hope this helps. Sincerely, Jennifer S. Intel Customer Support Which led me nowhere as most intel links do. make it idiot proof & somebody will make a better idiot.!
