OK, I have a modified-DIY-box below 70 C and running on 500 Mhz:
How do I get above 500 Mhz ?
Contact KNC, maybe they'll tell you, or add an option in the next firmware.How do I get above 500 Mhz ?
Could you post pictures of your set-up ?
Edit : Would these 20mm spacers work ? How many do you need per box ?

if they have open holes in the corners of the board, I do believe they'll work - though you most likely have to take the "box" off to fasten from the other side of the PCB.
they do...and you wouldn't even need a screw holding them in...just screw them in from the bottom...i did on my boards and works fine
course one in the middle wouldn't hurt too for support cause the heatsink is heavy and don't wanna warp the boardwhat size thread M5, M6?
It's M3, and you need 5
