I posted an idea here:https://bitcointalk.org/index.php?topic=482352.msg6222366#msg6222366 to resolve the shoddy work on the heatsink/pcb design in regard to it not making contact with all 5 GC3355 chips due to two components that are taller.

It's easy (if you have a steady hand) and takes about 5 minutes...afterwards you have perfect contact to all 5 GC3355 chips.

... and for your reference ...:

My post just above nst6563 post...explaining the reason for a bad contact between the chips and heatsink...

Good job, nst6563...

What are your results after the mod...any improvements...?

I've been able to run 1200Mhz stable (around 510Kh/s-515kh/s with 0 hw errors). I ran it last night at 1250, but it has more than 20 hw errors at 531Kh/s. Before doing this I was only able to run at 1125Mhz, I could hit 1150 but accumulate hw errors.
