I have the 3.2.
I made the change to the card in order to adjust the voltage Vccio. For high fsb 135 or 140 mhz these cards need high Vccio, 3.8V in my case to make windows boot at 140 mhz.
The problem however is the cache that normally takes 115-125 mhz and only in rare cases more. Without cache, however, the result super pi 1m is bad.
