I have 5x RX480 (Saphhire Nitro +) with Blockchain drivers and custom BIOS. I'm limited to 1000W power. I'm currently mining ETH + LBRY but I have some wierd errors. GPU stops every few minutes and then starts again... I tryed lowering dcri but no help.
Now my settings are:
Clock: 1050
Voltage: 950
Memory: 2080
voltage: 950
Can you tell me what settings on GPU do you use for this combination?
I think others have replied to this but just to add my tuppence worth, I think you are sailing to close to the wind with a 1000 Watt PSU and dual mining. It can depend on the PSU you are using, I have a 1000 Watt EVGA Gold (6 card rig) and it worked OK at over 1000 Watts (long story, but put a quick stop to that as it is not recommended). If your rig works OK mining other coins then you are probably over stressing your PSU, remember the rig will take a little extra when it first starts up and if the GPU fans start to run at higher speeds. I found dual mining too stessful for my poor cards.
Get a power monitor and check exactly how much the rig takes from the wall.
Depends on the quality of the PSU and allegedly the ageing of the PSU also reduces its capacity (I think the pace of ageing depends on type of use also). The rough estimate is about 10% a year so a rough calculation for 6 years of PSU use would be 1000 (0.9^6) = 1000(0.531441) = 531w
Ive wanted multiple PSU setups for ages and its more common now, probably an old deal on servers. Ive never heard of a PSU tester though, somebody knows no doubt
