Anyone Overclocking L9 or APW17/CV1835?

Looks like vnish released their firmware for the L9.
Anyone had experience overclocking it yet?

Curious how far the stock control board and PSU can be pushed safely. Vnish said 4600w, but that sounds sketch.

PSU is APW17 and control board is CV1835

Thats a lie shuts down 4200 watts thats when over current command kicks in
