Hello every one,
I have an odd behavior from dual mining
W10 pro
claymore 9.3
4xRX470 with 1500 straps
if I mine ETh only, everything is normal, after memory overclock, I'm 29Mh/s.
The probleme is, if I dual mine (DCR or SIA), my ETH hashrate is going super low. The only way to not loose too much hashrate is to choose DCRI 1 or 2 but in this case, it's almoste useless to dualmine.
And my memory overclock boosted the hashrate well in single mining but not in dual mining. +100 Mhz on memory? same result in dual mod, +10% in single mode.
I can see the monitoring showing that the GPU is almost always below 1 000 Mhz, even at super low dcri, at 10 dcri, it stays around 850 Mhz in dual ETH SIA.
In ETH only mode, it is higher than 1100Mhz. My GPU are even hotter in single mining than dual!!!
It was the same thing at stock clock/bios. When I was just testing, I lost 30% of my ETH hashrate when I tried dualmining on DCR (using the super basics configs that was as exemples in the readme.txt, I even didn't change the wallet adressses...)
I do use the GPU_FORCE_64BIT_PTR 0 and others.
Does someone have an idea?
thx folks
-powlim is the switch for Your dualmining success.
Of course You should have some power supply reserve to increase power limit at values of 20, 30 or more. Try first with values like 5 and see if it improves the speed. Increase in steps of 5, but when You reach 20 and need more, first check do You have to change max power limit value in Your GPU BIOS.
