KNC Jupiter overclock settings

[playersnoopy]

Anyone have best overclock settings for KNC Jupiter and what is max overclock to performance increase?

I just picked up a used KNC Jupiter (only has 3 modules atm) at stock it was mining at peak 520 GH/s with the 3 modules which is great not sure if it was ever overclocked to begin with.  Anyways I decided to overclock it and not sure what the capabilities are for this unit.  I got it up to 572 GH/s in the status page with an increase of 5-9 degrees C increase in all module and an extra 100watts draw.  I'll add some extra fans today but don't care about the extra power consumption so performance vs power is not a factor for me.  So I'm getting almost exactly 10% increase with 20% increase in power usage.  I've tried couple other settings and it pretty much won't go any better than 570 range.  Ghash is reporting relatively accurately with good runs hitting 700+ not that it's the actual hash rate.  Status page shows consistent 572-573 average hash.

I'm more than happy with the speeds just wondering at what settings is the max performance where any further increase has no effect basically.

thx

I saw that thread; sorry I should have clarified I meant using the web interface and adjusting the frequencies and voltage.
