Pencil Mod development.
I modded a one of my other ones, from ~2.2Gh/s to 2.9Gh/s, it ran for about 12 hours before seeminly dropping off, got home and found it's heatsink was coming off

( might replace it now, just apply heat

)
pencil mod, not very precise, don't push it too far. good thing is, you can use an eraser to undo it.
has anybody else taken a resistance measurement across R15 (in circuit) ? what do you get ? I saw 0.97Kohms before pencil modding, 0.87Kohms after, the one I took to 2.9Gh/s was around 0.84Kohms (too far).
