bfgminer 4.2.1 seemed to work for me to get my zeus thunder x3's to be able to submit shares at 65536 difficulty. only issues with 4.2.1 that i could see is that at 65536 difficulty it says 0 instead of 1. and now the upper limit for difficulty seems to be 65536 because 131072 won't submit any shares. so i just keep it at 65536 because dynamic sometimes goes up to 131072 and gets stuck there.
i tried several different cgminer and bfgminer that normally work at lower difficulties, but won't work with this pool until they lower the difficulty (i thought they were going to make this change soon, hopefully allowing difficulties down to 16384 or lower for smaller asics.) i would think the newest bfgminer 5.4.2 or newer would work best, but it isn't always the case. i'm not an expert on this hardware either, might be some bug with the way the hardware was made if no software works right. but at the same time we're looking at discontinued and unsupported hardware and software
here's my batch file for bfgminer 4.2.1 for two thunder x3 (setting chipcount and clock looks a bit different from other bfgminers):
Code:
bfgminer --scrypt -S zus:\\.\com18 -S zus:\\.\com22 -o stratum+tcp://prohashing.com:3333 -u spauk -p "a=scrypt d=65536 n=thunder" --zeus-cc 128 --zeus-clk 328
pause
bfgminer 5.4.2 batch file (never submits shares at 65536 though):
Code:
bfgminer --scrypt -S zus:\\.\com18 -S zus:\\.\com22 -o stratum+tcp://prohashing.com:3333 -u spauk -p "a=scrypt d=65536 n=thunder2" --set zus:chips=128 --set zus:clock=328
