But is the 0.5 official hive upgraded to the bugfix version, cause i cant get it working?, it just stops after listing gpus, like the 0.5 pre bugfix did?
I hope they did that - I forwarded the bugfix one day before publishing it here to the hive team - I hope they did that, but if not its not in my control. I hope they did that (else: if it still is the pre-bugfix it will hang on some 144/5 coins - one fix would be using "COIN" : "Auto144_5" and OVERWRITEPERSONAL : "TheCoinsPersonalizationString" in the configuration - with that you can mine any 144/5 even in the buggy version.
Well for ethereum that may work fine, but I guess for Equihash - that has more core demand - the settings may not fit so well, especially the low voltage. Try to go for 1200 / 1850 at a slightly higher core voltage (-100mv vs stock may be good point to start) . Ethereum is not sensitive for memory and regist bits flipping - that may cause the one or other hash to be invalid, but its a rare occurrence. In Equihash one defect bit can cause the miner to stuck, because its more using data dependent loops.
