Guys i must to clear this o-x what are these means;
every hash Cell must feed proper voltage and frequence so,
if you see - , this means = you dont feed this cell with proper voltage
(use higher Voltage,because some devices used on high voltage before we bougt)
if you see x , this means = your working frequence did not enought of Cell for live
(use higher Freq,because some devices used on high freq before we bougt)
if you see nothing, this means = This ASIC cell is not communicate with FPGA
(weak soldering or DEATH, if you lucky Re oven the hash board)
or you can try this when you see x or - => use web interafce goto Miner Configuration>General Settings then just click Save&Apply
you will see x or - gone because FPGA is resetted.
have a nice days.
i forgot this >Maybe reason of x-o stuation is broken fpga test communication, because asic test.sh working with cgminer when your system hashing.
if your system is hashing proper speed, you dont worry about that because its software bug.
And also write this calculation into your notes. If you want adjusting voltage and freq. You must to use my calculation;
Your Desired Clock Speed (depends Gh/s) x 0.00358(my constant) = Optimum Voltage Settings.
example if you want to use 187.5Mhz x 0.00358 = 0.671 V will be best energy eff. adjust.
i want to help peoples and hope to bugless products, so any donations is accepted if you be this useful. thanks.
