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

[batsonxl]

After a few hours mining my second GPU stops mining and I see 0.000 MH/s with the statement "wdog GPU2 not responding" and  "wdog Thread(s) not responding. Restarting."
But nothing happens.

I am not sure how to resolve this issue so I am looking for ideas here.
Below are the details of my set up.

Sounds like you got too much OC. Get low memory or increase voltage.

how can i set worker name? -worker didn´t work on EtcHash and wallet.worker also didn´t work.

Hi , i got the same card...

RX 580 Saphire Nitro - try MOD BIOS
Driver: Adrenalin 2020 20.9.1 = ok
Miner: Phoenix 5.3b = ok
cclock: 1170 = 1150
mclock: 2170 = 2100
cvddc: 850 = 875
mvddc: 850 = 875
Fan: 35

That could give you 30MH

hi i am new to ethereum mining and to PhoenixMiner can anyone explain why my 1060 6gb is only running at a reported 15.6MH/s when this chart https://www.kryptex.org/en/best-gpus-for-mining says it runs at 22MH/s? My GPU utilization is at 100% am I doing something wrong? I didnt see that the latest drivers from nvidia were bad.

Did you to go down on core and up on memory?

On linux i use -400/+600...for windows double those.  I get 23-24mhs per card limit to 80watts max.

no idea. I just started it after putting the info into the bin file under start_miner. Also I wasnt sure if this thread was active my b. I cant delete my topics as well weird. I run windows 10 with a stock settings on my 1060 does it make a huge difference with overclocking and undervolting? Are you refering to the in app GPU tuning parameter in PhoenixMiner?

afterburner is software that should let you adjust your core / memory / power level

https://www.msi.com/page/Afterburner

thank you. on my pool's website it says the reported hashrate has stopped at 0 what do i do?

If the miner is showing 0 then you may have to try higher core and lower memory oc settings.  move core up and memory down 50 - 100 at a time until it stays mining.  Watch the temp on your card.   Max safe for nvidia is 80c...i prefer to be 60c. 

thats the thing, I didnt overclock my card at all at the effective hasrate went close to zero and the reported stayed at zero for several hours. the pool website was still active but my miner software reported a hasrate of 15 consistently so it was mining but not reporting it what could happen?

Thank you for posting your numbers, this helps me tune the card.

I could use some guidance please.

I downloaded the new PM 5.3b to mine ETC again with some of my AMD 470 4gb cards. I have a test rig up with Win10 and 20.4.2 drivers installed. I have two cards that are the same except one is 8Gb and the other 4Gb. The 8gb card works fine of course, however, the 4Gb card only finds invalid shares.

https://imgur.com/jZELw2P

Not sure if my image will show up or not but I tried to embed an image.

Any ideas why the 4Gb card only finds invalid shares? I even dropped the mem clocks on the 4Gb card and added more power to see if that would help and it did not. I am about to install SMOS to see if that helps, but would really like to run Win10 if possible.

Just installed PM with SMOS and it is doing the same thing.

Phoenix,

Just an update on this issue:  v5.3b seems to be moving in the right direction - all of my GPUs mine, now, but they each see about 18MH less hashrate on v5.3b versus what I still get on v5.0e.  Again, with this version, downgrading to v5.0e resolves the issue without rebooting.  If it's helpful, the starting hashrate for v5.3b during autotuning is only about half of what it is in v5.0e.  I hope this helps.

I wanted to report an issue I ran into on v5.2e for mixed-gen ETH mining on one XFX RX 5700 8GB + one XFX RX 480 8GB + one MSI RX 480 8GB on Ubuntu 18.04.4 LTS (via minerstatOS) with amdgpu-pro v19.30 drivers.  When I upgraded to v5.2e, I saw my RX 5700 take approximately an hour to build its DAG file, and then yield 0 hashrate, and the two RX 480s only produced about a third of their normal hashrate.  I previously saw the same behavior with all PhoenixMiner v5.1x versions, as well.

Rolling back to v5.0e immediately resolves the issue without a reboot.  I have used a few versions of the PhoenixMiner for about ten months on this mixed-gen rig without issue, so this has been something introduced after v5.0e.  In case it's any help, I am including a few log excerpts, though I never saw any suspicious messages or error logs to report.

v5.2e log (note the miner uptime versus the DAG generation progress)

Thank you for reply.
same result, i even switched to another pool. this happens after 20 hours straight mining. Then i must restart the rig. after 20 hours mining miner tries to connect Devfee and it gives this error then all troubles starts. i dont know it something to do with my rig or miner.
after restart the rig all ok Devfee connecting but after 20 hours same thing again.

You can mine ETH til 27. 12 with 4gb I think, I can still mine it but i lost some MH/s with them. Ofcoure you can mine it, you just need to increase VR ram.

It depends on driver, OS and so on. On most of my 4GB rigs, the RX 570 4GB only produce 24mh and raising the virtual ram change nothing. 4GB are not enough to hold the dag, your hashrate decrease with every new epoch dude (every 5 days)

i have no issues mining 2 days with 5.3b

My MH/s drop from 30.8 to 24 on my 4GB RX470.

My settings:

Bios: MOD
Drivers: Latest adrenalin
Miner: Phoenix 5.3B (before that I used 5.1C)

FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

-epsw x -mode 1 -Rmode 1 -log 0 -mport 0 -etha 0 -retrydelay 1 -ftime 10 -tt 75 -tstop 80 -tstart 60 -fanmin 10 -coin eth -amd -cclock 1130 -mclock 2030 -cvddc 875 -mvddc 875 -daglim 1


What can I do?


I also lost few MHs on my rig with Sapphire RX580

Dropped from 32.7MH/s to 31.9 MH/s

Mining ETH? your 4GB has not enough Vram to hold the DAG file.

You can mine ETH til 27. 12 with 4gb I think, I can still mine it but i lost some MH/s with them. Ofcoure you can mine it, you just need to increase VR ram.

It depends on driver, OS and so on. On most of my 4GB rigs, the RX 570 4GB only produce 24mh and raising the virtual ram change nothing. 4GB are not enough to hold the dag, your hashrate decrease with every new epoch dude (every 5 days)

Try to switch to another server. Try eu1

Thank you for reply.
same result, i even switched to another pool. this happens after 20 hours straight mining. Then i must restart the rig. after 20 hours mining miner tries to connect Devfee and it gives this error then all troubles starts. i dont know it something to do with my rig or miner.

PhoenixMiner.exe -pool ssl://eu1-etc.ethermine.org:5555 -wal 0x17de26c0492fe296909dad7c979a8fa767de0252.RIG_4G -coin etc -gpus 2,5 -cclock 1150 -cvddc 900 -mclock 2000 -mvddc 920 -mt 1 -mi 11 -powlim -10 -amd -log 0 -rxboost 1 -gt 57

Can you try -pool eu1-etc.ethermine.org:4444

i tried it same thing. not only here. i tried 2miners pool and binance pool same result. i get socket error after 20 hours mining. it happens when Devfee tries to connect and it fails

[singlass]

such a shame my 7950 is only managing 11MH on ETC while this dude on youtube pulling 20+MH with 3GB 1060's ,i guess the old GCN's need a custom kernel / tweaking or something
