Is the mod done right on the ver 2? I can't see the insulation, however, I do see the pins in the enlarged holes on your photo? It was insulated but i removed the insulation before taking the photo as I was trying to check if it works with regular 133MHz Coppermines. And it doesn't work with any …

Hmm, so I wonder what may that be. I swapped the CPUs between slotkets and same SL5XL didn't work in V2. Do you have R750 or R560 resistor networks? I found out that under ver 2.3 sticker is ver 2 silkscreen. So ver 2 may be ver 2.3 without a sticker. Maybe my motherboard is more sensitive to signal …

You could try Omega Drivers, it helped me when I was trying to use very unusual AGP card with mobile Radeon 9600 chip under W98 EDIT: nope, they probably work only with Radeon cards 🙁 Maybe try some older drivers, like these http://vogonsdrivers.com/getfile.php?fileid=341&menustate=0

even with a 500C iron, the solder did not want to flow into the wick. Perhaps I need to place some flux directly onto the wick instead of having it touch flux-covered joints? Not really sure. You can try adding the flux directly onto the wick, it won't hurt anything. Hakko FX-600 is 50 watts and …

Depends what kind of tools you have. Do you have solder wick? Is soldering iron powerful enough? Are you using desoldering pump? You might try heating up the board with hot air or at least hairdryer (not to the point when solder melts, just make the surrounding area hot to touch), then use some flux …

All right, so gex85's microcodes work fine with Tualatin, but after I installed Dual P3-Katmai 450 PC unfortunately froze on POST screen (before memory count).
