Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[miner417]

I'm having issues with an RX 480 mining. Firstly I'm only getting a max of 22H/s, which I know is low for it, and secondly I keep getting these spikes that go down to like 17H/s, and it stays there for a bit then goes back up. Currently I'm just running base with base bios, but I tried a different Bios, and overclocking with Wattman, and I couldn't get any more performance out of it or make it more stable, does anyone have any ideas? I tried only mining Eth and not using the Dual mode, but it didn't help at all.

It's an MSI RX 480 Armor 4g on GPU0 that I'm talking about.

the 4 GB cards have slower memory, 22 is what they will do. 8 GB cards usually have the faster memory and will do 24.5. Bios modding will yield about 24.7 and 28 respectively. Core clock has very little to do with speed on Ethereum, but it will affect dual mining. Overclocking memory sometimes makes the minor slower because the card will use looser timings if it is not bios modded. To help with tips you can set the minor process to a higher priority in Windows task manager, or experiment with -dcri.

Okay, so that solves that issue. I tried a Bios mod and it didn't seem to help at all, stayed at 22. It seems like I get 21 on average. Do you have any idea's about the fluctuating of the speed though?

I'm pretty sure that with a RX 480 4GB 1750mhz memory you should be doing about ~27 mh/s eth with modded bios and a bit higher mem speed. Modded 8gb cards with 2000mhz+ mem speed are capable of ~30mh/s. Depending on the coin, dual mining can take the speed down a bit as seen from my rx 480 1200/2100mhz dual mining eth/sc: https://gyazo.com/42527769f77e8672d3e85b61df651082 vs eth/pascal: https://gyazo.com/6024bbe014d3542edd0e41601ee73a5b(i'm running lower intensity with eth/pascal so that's why its still pretty fast with eth).
So i would say that something is wrong, and you should try troubleshooting it. Try changing drivers to the latest ones or Catalyst (Crimson) 15.12, try changing the settings on the miner and try other clock/mem speeds on your GPU to see if it gets faster...

I tried a different Bios, but I couldn't find many that looked promising for a 4gb card with Hynix memory. I've also OCed the Mem speed to 1825, but didn't see a difference in the speed, I can't figure that out, or why the speed fluctuates like it does.

Hi there.

I'm having some issues with the devfee. It seems like it cannot connect to the mining pools defined by Claymore, so the miner stops working after some time.
Anyone else having this issue?

try to add -allpools 1 to you batch file.

I've done that.
The miner keeps skipping from dwarfpool to ethpool to ethermine until it stops, always with the same message: failed to connect, retry in 20 sec.
The strange thing is that I'm mining in ethermine myself, with no issues.

Any ideas?

v8.1:

- EthMan: added option for font color selection.

Thank you man! Finally!
 -colors 4 and there is clear yellow line. For all old lcd-s that purple temp line is hard to read

I think there is a bug on 8.1 ETH+PASC,  when i disable mining on any card the Total PASC hash rate does not decrease and ETH hash rate on that card stays the same.

[Dr_Victor]

Could anyone annaunce the gtx 1070 speed for eth+pas?

[marvykkio]

It would have been more useful to a higher speed of eth

[padrino]

It would have been more useful to a higher speed of eth

He mentioned previously he was going to try to squeeze a few percent more out, perhaps it wasn't possible after all..

Does anyone know whats up with this error?

server: bind failed with error: 98, next attempt in 10sec...

Hi, i just started mining with claymore. 5 RX480 red devils, and on of them keeps hashing low, i copy what im getting

ETH - Total Speed: 102.287 Mh/s, Total Shares: 139, Rejected: 0, Time: 01:35
ETH: GPU0 4.220 Mh/s, GPU1 24.774 Mh/s, GPU2 24.149 Mh/s, GPU3 24.665 Mh/s, GPU4 24.718 Mh/s

Can you guys help me and tell why getting that low hash rate

Thanks

I had same problem with simplemining Linux running Claymore.

I switched back to Win 10 no problems.

Im running Win 10. Crimson 16.6 for drivers...

That GPU seems locked in core clock and memory clock, dont know why.

Im ticking with the settings of my cards, two of them i get it cool working, but when i apply the same settings to the others two i get

WATCHDOG: GPU 3 hangs in OpenCL call, exit o WATCHDOG: GPU 1 hangs in OpenCL call, exit

Can someone give tips on how to solve this two issues...

I had the same issue with my 6x XFX RX480 rig and became more stable when switched back to 16.9.2 crimson driver. All cards are flashed with Boysie's 29MH Low power bios mod. Getting 173MH/s on 6x XFX RX480 8GB with 850W power usage from the wall.

Can you point me out the directions to get Boysies BIOS...

Boysie's BIOS are on the ethereum forums.

Here is a link to his low power BIOS. You can search for his other ones there.

I've been using Corsair 1000W supplies since I first started mining. I dual mined Eth + Siacoin / Decred and found the PSU pushed to the limit with 6 RX480s.

I've since stuck with mining Eth-only, but I'm building some new rigs for mining (6 RX470 4GB cards) and want to explore dual mining again. For dual mining Eth + second coin, is 1200W power supply enough?

I tried a different Bios, but I couldn't find many that looked promising for a 4gb card with Hynix memory. I've also OCed the Mem speed to 1825, but didn't see a difference in the speed, I can't figure that out, or why the speed fluctuates like it does.

I'm having the same issues as you for 2 weeks now, the speed drops for a while from 29.5Mh/s to 20 or 21 Mh/s, then goes back up again.
So far i've tried different bioses, installed new OS ( tried win 7/10 ), but can't figure out what the problem is.

I have tested it and it does not run stable. Sometimes it runs 30h and freeze, othertime after 2h it freezes my Windows 10. Tried with different Catalyst versions. You will see...

Maybe you have the port blocked by your provider, it happened to me, port 4444 is blocked.

Sorry , for use only ETH with 2 board ? ( i have 6 gtx 1070 )

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal address -epsw x -di 1 2 <------ ( this -di 1 2 work only 1 board )

Thanks .

I gave a try this miner yesterday (usually mining xmr, but seeing the current eth profitability ...  ).
The miner works ok, even though the power consumption increased a lot compared to XMR, but this is quite normal since ethhash is more power hungry than CN.

However i noticed that my primary adapter's speed is way lower the the other cards. All my cards are RX470 4GB, running at around 30MH/s while the primary GPU is runing at around 11MH/s (the same ratio can be observed with decred mining : ~380 vs 140).
I tried to lower the intensity, and to switch to mining only eth, no difference at all.
Any idea why?

(On XMR there the primary GPU performs less as well, but is only 10% behing the others or so)

[adaseb]

Anyway to use the "ttli" when the first GPU is disabled?

Like I am running ETH mining with -di 12345

The first GPU is mining XMR. But when GPU 0 is running hot, it throttles the first GPU (di 1) with the ETH miner.

The temperatures are mapped at the start of GPU0, and not necessarily the correct GPU.

[cryptohunter]

for eth only what speeds are people getting for

7950
7970
380x

thanks

I have 4 gpu rigs and only getting about 50hs total per rig according to coinotron? this is wrong or correct? i was hoping nearer to 80? perhaps?

For the 7970, it is less than 10 MH/s .

[miner417]

Can someone help me figure out why I can't get anymore than 22 MH/s on my MSI RX 480 4g Armor? I keep seeing people say how they're getting 28-30 on a similar card, but I can't figure it out. I've tried a different Bios and Overclocking, but it really doesn't seem to do much. Is there a specific Bios for this card that I need to us? It has Hynix memory. It just feels really weak to what everyone else is getting.
