Yesterday i was at microcenter and I looked at the back of a retail 2000+ and guess what ... same code as mine
Mine can hit around 1.85 ghz after that it doest post...if I went water I could prbably squeeze a few more mhz out of it...but thats a later upgrade as my sk-7 and super loud case cools good enuff for me.
AGOIA 0212 Y does 176FSB
AGOIA 0213 Y does 185FSB
AGOIA 0204 K not sure what it does never installed it
and my new one AGOIA 0226 Z, just put her in have it at 166FSB, would be pushing her today but a BIOS flash went bad, so I am waiting for a new motherboard...
The one thing I am sure about with most of AGOIA 1600+ is that they will do 166FSB right out of the box(or OEM package), and that's not so bad an extra 350MHz just for plugging it in...
