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...?

ZiG

ZiG, I saw a post where you had said you were able to run up to 1000MHz stable with the thermal mod above. Is that without doing any of the voltage mods? TIA

Yes, buddy...

This is what I am doing first...test them as they come...stock...no mods...@850MHz ...to check how good are they...each one... Wink

Second...: Apply the thermal mod...Paste...new, thicker, better thermal pads...shims, if nesessary...TEST again...Most of them are going to 950 min...1000Mhz...NO volt mods yet...!

Out of 10 => 4 @ 1000...4 @975...1@950 ...1 slacker @925MHz ...NO HW errors...this is my belief that every HW error is lost...non submited...unpaid work...this is like your miner STOPPED for this period of time...5-10-15 min...so I opted for NO HW errors at all...

Voltage mod next...I am using my own...Test again...etc...

Capisco...?... Grin

It is just me...you could create your own test/mod...

Cheers...Beer here... Wink
