Unlike the 2000 and 3000 models, the 3500TV didnt generally have large overclocking headroom. Still, you should be able to hit 190/190-193/193 without much trouble, and some of them could hit 200.
If your lucky and you happen to have one of the later V3's produced then it's conveivable that you may get beyond that, I once had a V3 3000 that would do 218/218 smooth with a bit of additional cooling.
