So for now, I have a 970 and 1070 in a rig. I'm getting 420 MH/s from those two, at around 260W. Does someone has ideas to improve this without damaging the cards with too much OC or running them at near no electrical cost but to get pennies ?
420MH? I'm sure you meant 42. but you can try undervolting and overclocking. you can also mod them and switch the BIOS.
Oh my bad ! I forgot to state that it was on LBRY. It seems I though it was evident, but it isn't. I'm looking for precise value for the overcloking and the undervolting. I can easily increase the hashrate by 10%, but the underclocking part isn't working. GPU-Z still gives me the same TDP use.
Each card is different and you will have to find out the limits for your cards. maybe you won the silicon lottery. usually a 10% increase in clockspeed results in close to 10% more hashrate, not sure if it's true for LBRY's algorithm.
And I wouldn't trust GPU-Z for the wattages. get a kill-a-watt if you want precision.
My wattmeter is on the go, but it won't arrive until next week, so for now, I need to use what I have under hand
. I have in some way "won the silicon lottery" with my Samsung memory card. So I guess that until I manage to have my wattmeter, I won't be doing anything interesting since I want to increase the clock speed but without changing the power consumption.
