the TI 200 bios seems works well with my standard leadtek gf3. Seems to help stability at agp4x, still cant seem to get sba working tho.

Not for nothing, but by flashing a standard GF3 with the TI200 BIOS didn't you just technically "dwongrade" you card?

The same really seems to me.... you must try the I500 bios.

ok just flashed my Visiontek Geforce3 (regular)BIOS# 3.20.00.10.02 with the
Ti500 BIOS, which is version# 3.2.00.18.X25
Not much new so far beside the fact that the coolbits slider now starts with
an highier value and allows to gu much highier, the card itself (as
expected) won't go highier then my current 240/530
Going to run some benchs and see whats new
