Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v10.0 (Windows/Linux)
I'm selling my Gtx 1060s because they are not very good at mining. Whether it was the Hynix memory, or the bad components used, I only got 17Mh/s out of each card after OCing without touching the voltage. I cut my fingers twice with the fan blades, and whenever the network difficulty changes some of the cards hashrates drops to 1Mhs. I'm getting 22 Mhs from 570 8Gb and want to know how to increase hashrate other than increasing the memory clock, thanks.
Just get out now while you still can. Those GPU's going to start taking toes.
Stop takin a P00P at him
To the OP : Look up Bios modding, your 580 8GB should be able to get 29mh easy peasy at low overclocks.
His "570 8GB" should hit 29.5 with alt ethash coins or 29 if he is using windows 10+ Claymore 10 + Blockchain drivers. Also dual mining LBR he should get about 65 mh's with LBR or about 730 with DCR
All he has to do is A. Up the memory clock B. Run Polaris 1.64 and click the Memory Timing button to load the specific memory timing for the card. Nice new feature of the Polaris fork" and he is good to go, Also I would put the following in the Start.bat for his 570 -cclock 1175 -mclock 2050 -cvddc 900 mvddc 900 -dcri 20 (with LBR) -dcri 25 (with Decred)
Where do you put the cvddc settings, at the beginning of the file or the end? And also can you undervolt Nvidia cards too?
It makes no difference where you put it in the command line. As noted in the Claymore README, Nvidia cards don't support undevolting. You can adust the power limit % on Nvidia cards using Afterburner in Windows, which reduces the power consumption target when set at a negative value.
I put this in the Bat file, it seems the voltages have gone down but I didn't see much difference in Gpu-Z for the 570. Maybe it's because I have apply oc settings on Afterburner.
Can anyone comment on the power consumption for the RX580 cards. I have two rigs each has 6 RX580 and both are dual mining ETH+LBC (Eth: 176 Mh/s + LBC: 510 Mh/s). Each rig consumes about 1020 Watts reading from the wall-meter while GPU-Z reads less than 130 Watts for each card. I think they should all be around 6*130 + 70(system) ~ 850 Watts total. My setting (-cclock 1150 + -mclock 2100 -cvddc 870 -mvddc 870)
The power usage shown in GPU-Z is for the card VGA power connectors. You also need to add 40-50W for each riser. 1000-1100 W is about right for a six card RX 580 rig when dual mining.
The risers themselves do NOT use anywhere close to even 40W. The power load for risers is negligible even with six of them. It's the GPUs themselves that are using the power.
I don't think the power sensors in GPUs are all that accurate anyway plus they fluctuate so wildly.
I have switched all my RX BIOSes to Anorak's powersave versions. I lose about 3-5% hash rate but it saves almost that much in power and reduces heat output and wear on the cards.
When I see 6 GPUs consuming over 1000W and then I look at an Antminer that can produce 4x more revenue on 1200W I wonder why I'm even bothering with GPUs...
You are wrong. powered risers use between 40W - 50 W each, which is NOT reported in GPU-Z. This is easy to verify in a dual PSU setup like I have where all the risers are connected to the same PSU as the motherboard and the secondary PSU only powers the tops of the cards.
