My guess is your current BSOD problems are the CPU, not the board version. The 1700+ is a 266/133 clock, so getting 333/166 out of it isn't half bad. Most of what I see on the Asus site indicates what you have should be okay with a 3200+/200 or 3000+/166, so that means the 13x multiplier is available. I don't OC (not fanatical about it, just need stability more than wringing out extra performance), but bumping up the clock always seems less tricky than playing with the multiplier.
Since you are getting 333/166 out of it now, I'd probably go the 2500 or 2600 route. worse that can happen is you wind up with a 2500 or 2600, which isn't bad. The 2500+ was the chip of choice for OC-ing for a long time, and people were getting it up to 11 x 200 pretty consistently. I suspect, as Osage said, you'd have just as good of luck with the 2600, though.
