PhoenixMiner 6.2c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

[melpheos]

OK I did some more investigation.
For some reason, ETC speed is half the speed of ETH speed with the same batch file.
This doesn't make sense in my view. Am I missing something

This is due to the difference in DAG size, ETC has the largest DAG and some gpus architectures have degraded performance for this reason.

Thanks but that doesn't make sense in my case.
I have 1070ti card and I get HALF the speed of the ETH with ETC.
Currently, I should lose at most 1mh/s with ETC on my setup so there is something else going on

It really makes no sense ... now that I have read your post again and get it, have you tried removing drivers with DDU Uninstaller?

[qqqq]

Hey, thanks for the add "-rate 2" parameter, very smart idea.

Another one request, i have to use ddns services for one of my farm and it just doesn't work with http://xxxx.ddns.net:8545 for solo mining (Doesn't decode host to ip). When i using xxxx.ddns.net:8545 without "http://" the miner thinks this is a pool instead of a local wallet but decode a host to ip proper. Could you please implement some workaround for it. Thank you!

Yes, also tried various drivers... Same drivers, same miner, same cards all across 4 rigs of 6 cards with the same result...
I'm going to test with another eth miner to see but if someone else saw this issue, i'm all ears

I switched to ethminer 0.19 and i'm back with normal values (29-30mh/s for each card)
Seems like a bug on PhoenixMiner with ETC

Looks like I have the same issue with Claymore (with even worse performances on etc)

The only miner that gives me good performance is the alpha of ethminer 0.19 the issue being that this miner is unstable and crashes frequently

[Digital_Seytan]

Why mining PM on nicehash dagger pool ETC mining is much slower than ETH, you can't help it PM DEV

[melpheos]

Confirmed, got the same issue on 1070TI: hashrate drops to 17-20 MH/s when mining ETC. Tested on Nicehash and Ethermine ETC pools.
Tried almost all avaiable miner software (PhoenixMiner, Claymore, GMiner, Ethminer 0.18/0.19a) and always got the same result.

At least I'm not alone. That would be very surprising if this was because of the DAG file size difference.

Looks like there is an issue with ETC right now but this occurs with all miner except for ethminer .19 but this last one crashes (at least for me)
Either it's the dag file size issue reported above but in that case that means that the issue will occur with ETH as well in a few weeks

Either it's the dag file size issue reported above but in that case that means that the issue will occur with ETH as well in a few weeks

if you want to simulate this bug in ETH, you can use Benchmark mode and report the same ETC dag epoch.

Code:

-bench [<n>]

Nice catch...
Indeed, if I run phoenixminer with epoch 320 (current etc epoch) the speed drops by half...
With such a small difference in dag file, there shouldn't be such a speed difference so I guess it's a lack of support
Actually, running anything above 310 gets a speed drop of 50%

[PhoenixMiner]

OK, here are some results from one of our test rigs that runs 24/7:

• PhoenixMiner 4.9c, Windows 10, Nvidia driver 397.64, common parameters for all cards: -mi 14 -tt 63 -fanmin 20 -fanmax 50 -tmax 66
• 1070: -mclock +440 (4248 MHz final mem clock)
• 1070 Ti: -mclock +440 (4248 MHz final mem clock)
• 1080 Ti: -mclock +756 (5872 MHz final memclock), also using the ETH "pill"

We use power limit in order to optimize the power consumption as using -cclock for Nvidia cards is inferior (doesn't lower the core voltage enough, resulting in higher power consumption than necessary for give clock speed).

First, here are the results (both hashrate and the reported power usage) with lower power limit (i.e. with optimized power consumption):

Card	ETH (epoch 310)	ETC (epoch 321)
1070 (-powlim -50)	28.54 (99 W)	27.93 (99 W)
1070 Ti (-powlim -45)	30.48 (99 W)	30.48 (99 W)
1080 Ti (-powlim -25)	48.44 (185 W)	46.42 (188 W)

Next, we increase the power limits to offset the hashrate drop of the cards with the increase of the DAG size (note that depending on your power cost, maximizing the hashrate regardless of the power consumption may be a losing strategy):

Card	ETH (epoch 310)	ETC (epoch 321)
1070 (-powlim -30)	30.36 (132 W)	30.36 (132 W)
1070 Ti (-powlim -25)	30.52 (135 W)	30.52 (135 w)
1080 Ti (-powlim -5)	54.63 (241 W)	52.01 (238 W)

As you can see there is hashrate drop with the increase of the DAG size but it is nowhere as dramatic as 50% for ETC. Additionally, with 1070Ti the drop is almost non-existing, so there is definitely something wrong with your setup. We suggest adding the -hstats 2 parameter to see the actual clocks and power consumption, the reason for power cap (pcap) if any, and so on.

Thanks for taking the time to check.
I'll run a test this afternoon and see but as far as I could see, the power consumption was the same on ETC and ETH.
Also a few other people have the same problem with disastrous performance in ETC vs ETH...
I have much more virtual memory allocated than necessary so no problem there and have no issues with any other algorithm so I'm really confused here and really can't see what could cause this issue.

[skinnyfalcon]

This is on a mixed RX 570/580 rig, 12 GPUs all 8 Mb. Running on latest Windows 10, AMD driver and Pheonix.

With individual memory clock settings I was able to achieve 372MH, and ran it this way for a long time without crash. A few updates ago the system just started to crash randomly, can't get the rig to stay on for more than 30 min at a time. After changing the individual clock setting to single setting (to the lowest out of the 12), magically the rig has been running more than 2 days straight with no hiccup. The overall hash rate has dropped a little, from 372 to 361 Mhz. Lost 3% in hash power but the rig is running steady with no reboot.
I do not know if this is happening on Nvidia.

I have seen posts where people have mentioned the dev knows this problem.

@Pheonix Devs: Any chance this is going to be addressed soon?

Here are the result going from 310 to 311 (remove the dag % generation for readability)
Nothing stands out

[krinjah]

There might be an issue with ETC itself. I'm getting no more than 20mh/s on my RX570 4gb while mining ETC and a stable 30.5 mh/s on other ethash coins (including ETH).
Unfortunately I don't know the reason and how to fix that.

[Digital_Seytan]

PM DEV where is a PM update to solve the ETC problem. Now, unfortunately, we have to set much higher power to get somewhat higher Mhs.

     Please Help

[krinjah]

My problem with ETC mining had disappeared as suddenly as it's appeared.
I've done absolutely nothing and 30 mh/s is back again.

Hello, i just move from windows to linux and i have few questions.
Because in linux amd seems to not having a gui to OC the GPU, i did try to use the oc method from the miner but no effect.
Can someone make some give me solution for my problem?in windows i had 31Mh/s and now 21 22Mh/s.
Thank you.

[Semtex72]

With RX 5700 it is better to use old drivers? Newest seems to degrade some percentage?

What are you currenty using and can yu share your settings?

Did you try to put one same settings for all cards ( lowest, from worst card )? Strange but that helped me.

Thanks for your answer, but my problem sems to be kernel or amdgpu driver.At stock settings i get 21 22mh/s gpu rx 580, if i oc by 1+ mhz the vram i get less performance 18 19 mh/s. On windows i was using 2180 for vram and was stable.
