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

[earlybird36]

Is hashrate really fluctuating with Phoenix Miner?  My radeon 7 and rx5700 hashrates are very inconsistent. GT on autotune, driver 20.12.1. I tried Team Red Miner and it was consistent.

Hi,

I've been mining successfully for about 2 month now - no reboots. PhoenixMiner has been working perfectly.

All of a sudden about 2 hours ago, I'm getting every share rejected.

I've tried switching to Nanopool but I get the same.

Any ideas?

Do you use latest version? 5.3 has problems.

Can you help me please. I have 4x Rx580 and 1x Rx5700, and amd driver randomly crashed. In log i can see hashrate of rx5700 jump high 469mh, and drop to 0mh.

The same thing happens on 20.9.1 and 20.11.2 version driver. I revert default clock for rx5700 and problem it happens again.

Do you have advice how to solve this problem.

i use 5.4c Phoenix miner.

I had the same problem and it looked to me that as times passes the number of crashes went up. Up to a point where it would crash 2-4 times per day. I updated to driver 20.12.1 and phoenixminer 5.4.c and now its been running for 10 days without any crash (i hope i didnt jinx it now).

Maybe updating to 5.5.b will help you as it uses new kernels. Definately worth a try to update everything

I hope it helps you too!

I just started having the same problem.......mining on Nanopool and every share started to be rejected. I have been running all week with no issues........

I've just upgraded to 5.4 just in case...same problem with ethermine or nano pool

its just constant rejections.

Some info from the log:

2021.01.21:21:45:53.683: eths Eth: Share actual difficulty: 4635 MH
2021.01.21:21:45:53.702: eths Eth: Received: {"id":4,"jsonrpc": "2.0","result": false,"error": "Provided PoW solution is invalid!"}

2021.01.21:21:45:53.702: eths Eth: 3 consecutive shares rejected by the pool

2021.01.21:21:45:55.735: GPU1 Unable to submit ethash share - pool disconnected

Tried the beta 5.5b also...no luck, all shares rejected.

My rigs are fine but seems like a few similar issues suddenly got reported right about when the dag epoch changed from 389 to 390. Since ETH passed the 4GB dag size these new epoch seem a possible cause of crashes/issues depending on your GPUs, drivers, and PM version. Its happened to me a few times and always fixed by rebooting the rig and restarting the miner.

it might coz epoch/dagsize change

i can say that coz my 4gb gpu decrease hashrate

[CGS_CC]

Any way to configure miner to start a new log file for each new day?  if I pause miner and restart will it create a new log file? or will it just continue on the current log file?

I just started having the same problem.......mining on Nanopool and every share started to be rejected. I have been running all week with no issues........

I am also have this problem. I have six rigs that were all mining since November when 4 gig opened back up and I switched from claymore to Phoenixminer. Although the hashrates have been decreasing over the past month, starting this morning they all skyrocketed back to their maximums I’ve ever seen. About 30 per card. However nanopool shows them all off-line and rejects transactions. I have been using Ethos with Phoenixminer 5.4b. I upgraded 1 machine to 5.4c with the same issue.  I looked at the miner log and it looks like there’s something going on with the Epoch 390. I get the error “not enough vram for dag Epoch 390”. Is this the end of mining ETC with 4 gig cards?

Thanks in advance to anyone who can offer me advice,

Ken

Yes, it happens because of overclocking. Don't overclock your memory too much...

Memory is not overclocked that much. I noticed the fluctuation started when we switched to epoch 384

Hi, I was trying to run my old rx580 on the same win machine I am running 3x RX 5700 and it was mining with 8MH/s and it was not stable. Any ideas? thanks!

Hi, I was trying to run my old rx580 on the same win machine I am running 3x RX 5700 and it was mining with 8MH/s and it was not stable. Any ideas? thanks!

I Have the same issue 4x RX580's and 2x GTX1070s. ***all 8GB CARDS***
All perfectly stable for months then all of a sudden approx. 4pm UK time yesterday, nothing will work.   Also went back and took a look if claymore worked...it did not.

Is this anything to do with the minor pools trying to go against the bigger ones?

I'm hoping someone with more experience can help on this forum.

Which OS do you use? I had problems in Win 7. 6 * gtx-1070. After switch to Win 10 all works.

Would it be possible to reload the config.txt with "c" key forcefully? 

For example:
1.  I press "c" and my config loads up hardware parameters.
2.  I go into a different application and adjust GPU power/clock/fan.
3.  If I press "c" again on the miner, it doesn't reload my settings. 

It doesn't know that hardware parameters were changed elsewhere.  My theory is pressing the "c" key reloads config.txt, compares it with the current set of parameters, then only applies parameters that have been updated.  It does not forcefully reload the entire config.txt.

Some extra info... all my cards are 8GB, so I don't think this is a 4GB card issue.

It seems as time goes on, more and more miners are getting this issue and it does not seem to resolve by changing pool.

As I had my rig running the most sable it has ever been (moved from claymore), I'm reluctant to change drivers/bios etc. as it seems a 'sudden' change has caused this... I just can't figure out what.

I have a couple of miners setup for RDP. Phoenix Miner will not generate a new DAG unless you are connected via RDP. The program is running as admin. Generating the DAG is not an issue, as I used the -bench to test multiple times in different configurations. I just verified this was the issue as I watched during the recent DAG iteration.

Any help is much appreciated! Thanks!
