Where is the 3.6v I/O voltage jumper on a P3B-F?

[EvilDonnyboy]

A friend of mine has this board, and he wants his ram to hi higher. I suggest for him to try upping the I/O voltage from default 3.5 (it's 3.3v on some boards) to 3.6v. I know where the jumper is on my P3V4X, but I don't got a clue where it is on the Board, or even if it has the jumper at all.

If anybody could clue us in, we'd be greatfull.

the jumper is located at the top edge of the board(looking at it in the case) just to the rear of the last dimm slot. its JP20
3.50V=1-2
3.65V=2-3
