Okay, my 'non-pencil-trick' mod is:
Replace C36 10nf with a 100nf capacitor = no more pencil tricks! 'yay'
This includes the other 3 mods i.e. the two jumpers and resistor change out on page 14 (Sandor's mods) of this thread.
I have run over 36 hours with ZERO hardware errors - 1000MHz (stable) at 568KH/s peak - 378KH/s average pool side .07% stale shares out of 587,114 valid shares. Comm port FIFO's were set at 14 Receive and 16 Transmit.
It's still running strong and stable. So I believe this mod is a pass!

I"m looking forward to trying out nemercry's mods when he finally releases the particulars. His results sound fantastic!

As usual, if you do these mods, you do them at your own risk!
