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

[sys2007]

Using WIN 10
5.2A, Ethermine, Etherium, driver  20.5.2
RX5500 4 Gb card, together with -daglim 1 gives out only 3MH!
Will there be support for 5500 4Gb cards?

[Dowper_]

-cdmport is not working in the new version...

It is working fine here (read-only access).


CMD-Line used:

On latest 5.2a version it's not working.

I know this is the mining thread but let me just say this - with Christmas and other holidays coming around the corner it might be prudent to get rid of the 4GB cards now while you have an easier chance to offload them. You can probably mine another $10 of ETH with free electricity doing all this miner tricks of partially loading the DAG but it is a losing battle (unless you're switching to ETC @ 390). Ultimately the goal is to have the most income, and sometimes that means getting rid of older hardware and just buying the coin or using proceeds to buy newer cards.

[Littlegrand]

guys.

all 4gb cards can't mining anymore

Mine are all running just fine...on eth...on linux...30 some odd 4gb 570s
Mine rigs are on 5.0e and one is 5.1c.

So appears soon i will need to update the miner. 

What is your linux/driver setup?  Having trouble getting linux stable on Ubuntu 20.4

[FEKIH]

Where I add this (set -daglim 1, or see bellow how to use the -daglim option; you also need to add -dagrestart 1 to allow maxium possible value of -daglim)

[lastfelix]

Hi there is a low performance problem, my card is also available card rx 5500 xt 4 gb giving4 mh/s I tried different drivers but it didn't fix I tried in different programs, there was no solution

[PhoenixMiner]

PhoenixMiner 5.2b (still beta) is ready with some fixes. You can download PhoenixMiner 5.2b from here (this is only the Windows version, the Linux version will be ready in a few days):

(MEGA links are no longer active)

If you want to check the integrity of the downloaded file, please use the following hashes (you need the last file PhoenixMiner_NVRTC_Windows.zip only if you want to mine BCI with Nvdia cards under Windows):

The fixes in this release (since 5.2a) include the following:

• Fixed some issues with allocation failures and crashes with some 8GB AMD cards when mining ETH or ETC
• The -dagrestart is set to 1 whenever -daglimit is active for 4GB AMD cards

The new features in 5.2a are:

• AMD cards with more than 4 GB RAM will now work without issues until DAG epoch 450
• Added new -daglim parameter to allow a few more weeks of work for 4 GB AMD Polaris cards. Use -daglim 1 for automatic operation, or specify a concrete value for the maximum DAG size (example: -daglim 4000 will set max DAG size 4000 MB)
• Added -rxboost parameter (also accessible via -vmr) to boost the performance of GDDR5 based AMD cards (Polaris or earlier)
• Added memory straps support for AMD Vega cards. Use the -straps command-line option to activate it (example: -straps 1 will activate the lowest strap level)
• The Nvidia memory timing (straps) option is improved and now is turned off during DAG generation to avoid any possible instability issues
• Many other small improvements and fixes

Here are some additional notes about the VRAM timing adjustments of Nvidia 10x0 cards:

• Using -rxboost, -vmr, or -straps on AMD cards requires running as administrator (or as root under Linux), so you need to run PhoenixMiner as administrator for the VRAM timing options to work. Note that the -mt option will still work without running as administrator/root.
• The -rxboost option is only supported on GDDR5 cards (RX4xx/RX5xx or older).
• The -daglim option works only on Polaris cards (RX470, RX480, RX570, RX580, RX590). It limits the DAG size to <n> MB to allow mining on 4 GB cards a few weeks after epoch 373 on Windows (or after 380-383 on Linux). The possible values are the exact DAG limit in MB, or 0 (turn off the DAG limit, this is the default), or 1 (automatic DAG limit size, usually around 4006 MB under Windows). Note that the  hashrate will drop significantly with each epoch after the DAG limit is in effect. If the hashrate drops too much (e.g. from 28 MH/s to just 2-3 MH/s, you need to use lower value, for example -daglim 3950
• The VRAM timing options can be quite different between the GPUs, even when the GPUs are the same model. Therefore, you can (and probably should) specify the VRAM timing options separately for each GPU.

Please let us know if you have any problems or questions related to PhoenixMiner 5.2b.

[UnclWish]

PhoenixMiner, thanks for updates!
1. Please wrote recommended driver versions for 4Gb and 8Gb cards.
2. eres option didn't work now? Miner didn't show max DAG when building caches...

Guys, everyone who did everything right, but the hash rate remained small (for example 1.5), you just need to reboot the pc  
I added the following to my old bat file
-daglim 1 -dagrestart 1 -eres 0 -rvram 0 -rxboost 1
as a result RX 470 - 26 Mhs
Thanks, Phoenix !
P.S. drivers 19.4.3, 8 Gb ram

Hello Guys, thanks for the info
RX580 4GB works like magic with the updated version just some issues with fan control and speed.
Windows drivers 20.8.1 i was running with 4-5MH/s roll back to Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23 and with help of Phoenix now i have 27.5MH/s
PhoenixMiner.exe -amd -daglim 1 -dagrestart 1 -eres 0 -rvram 0 -rxboost 1 -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal WA -proto 3 -dpool blake2s.eu.nicehash.com:3361 -dwal WA -dcoin blake2s

The second issue is that i cannot double mine, what i do wrong?

Thank you again for everything

The new alpha version is ready. You can download PhoenixMiner 5.2a from here (this is only the Windows version, the Linux version will be ready in a few days):

If you want to check the integrity of the downloaded file, please use the following hashes (you need the last file PhoenixMiner_NVRTC_Windows.zip only if you want to mine BCI with Nvdia cards under Windows):

The new features in this release are:

• AMD cards with more than 4 GB RAM will now work without issues until DAG epoch 450
• Added new -daglim parameter to allow a few more weeks of work for 4 GB AMD Polaris cards. Use -daglim 1 for automatic operation, or specify a concrete value for the maximum DAG size (example: -daglim 4000 will set max DAG size 4000 MB)
• Added -rxboost parameter (also accessible via -vmr) to boost the performance of GDDR5 based AMD cards (Polaris or earlier)
• Added memory straps support for AMD Vega cards. Use the -straps command-line option to activate it (example: -straps 1 will activate the lowest strap level)
• The Nvidia memory timing (straps) option is improved and now is turned off during DAG generation to avoid any possible instability issues
• Many other small improvements and fixes

Here are some additional notes about the VRAM timing adjustments of Nvidia 10x0 cards:

• Using -rxboost, -vmr, or -straps on AMD cards requires running as administrator (or as root under Linux), so you need to run PhoenixMiner as administrator for the VRAM timing options to work. Note that the -mt option will still work without running as administrator/root.
• The -rxboost option is only supported on GDDR5 cards (RX4xx/RX5xx or older).
• The -daglim option works only on Polaris cards (RX470, RX480, RX570, RX580, RX590). It limit the DAG size to <n> MB to allow mining on 4 GB cards a few weeks after epoch 373 on Windows (or after 384 on Linux). The possible values are the exact DAG limit in MB, or 0 (turn off the DAG limit, this is the default), 1 (automatic DAG limit size, usually around 4005 MB under Windows). Note that the  hashrate will drop significantly with each epoch after the DAG limit is in effect. If the hashrate drops too much (e.g. from 28 MH/s to just 2-3 MH/s, you need to use lower value, for example -daglim 3950
• The VRAM timing options can be quite different between the GPUs, even when the GPUs are the same model. Therefore, you can (and probably should) specify the VRAM timing options separately for each GPU.

Please note that this is an alpha release, we rushed it because the epoch 374 is just a few hours away and because of the problems with DAG epoch 385 on ETC and AMD cards. Please let us know if you have any problems or questions related to PhoenixMiner 5.2a.

Thats nice:) Thank you! some weirdness on the last GPU, but seems to be working nicely (4008-4009 is the malloc on these 4GB 570 Nitros):



TeamReadMiner with its crazy reset routine can actually fit 374 DAG proper, but somehow if its more than 10GPUs - it's not loading
(also 470 REFS are hashing now fine on teamredminer)

same rigs looked like this before the threshold cross:



19.9.2 and 20.4.2 are ok. (20.9.1 can be somewhat better)

eio? iomap64? miner showing up as 5.1 still and marked as malware by the first time in pheonix miner history?
did pheonixminer get hacked?
