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

[Crash95]

IMPORTANT! All owners of AMD cards with 4 GB RAM must upgrade to PhoenixMiner 5.0e or later version to continue mining after DAG epoch 350 (both ETH and ETC has already passed DAG epoch 350). Additionally, here are some important tips for longest possible usage of 4 GB AMD cards with PhoenixMiner 5.0e and later:

Just moved to lolminer because today on this epoch (371) my 4gb cards stops hashing, cant realoce VRAM
Any future release to solve this problem?
I got all good configurated and switch from claysmore 2 months ago to PM and worked flawless until today.
I got too one 8gb card on the system and one vega. (This two i use PM)

Thanks

Same here !

hi
my rx580 8gb stop mining ETC at #379 epoch (4GB DAG size) in win10 & PhoenixMiner 5.1c
but still work ETH at #368 epoch.
my driver is Crimson Beta for Blockchain.
i dont have any problem in linux but some rigs work in win10.
any suggestion?
 

Good drivers. These are versions from 18.12.1.1 to 19.7.5 (inclusive), and from 19.12.2 to 20.8.1 (inclusive). These will allow you to mine until DAG epoch 372-373 and won't need restart of PhoenixMiner on each DAG epoch change.
Not so good drivers. These are versions 18.1.1 to 18.10.1 (inclusive), and from 19.8.1 to 19.12.1 (inclusive). This will allow you to mine until DAG epoch 365-366 and will require restart of PhoenixMiner on each DAG epoch change (for these drivers this will be preformed automatically unless you have added -dagrestart 0 command-line option to explicitly disable the auto-restart).

Your 8GB RX580 should be able to mine ETC without issues though, even with Blockchain drivers.

but my 8gb rx580 stop mining ETC...
the problem is PhoenixMiner 5.1c!!!
this miner dosen't support after #379 epoch (4GB DAG size) in win10.
any one can mine ETC in win10 with 8gb gpus on PhoenixMiner or claymore now???

I had the same problem bro on blockchain drivers. Try last Adrenaline drivers version 20.10.1

Blockchain drivers are deprecated
I use 19.5.2 that should work.
 

First post says:

"

    Do not upgrade to a new AMD driver unless it is explicitly supported by PhoenixMiner. With 4 GB AMD cards, this will not only lower your hashrate but it will make impossible to mine when the DAG epoch is above 350.
    After the DAG epoch becomes more than 350, the optimal -gt value for the 4 GB AMD cards may change. So, we recommend to run auto-tune again after DAG epoch 350 to find the best GT values for the cards.


After extensive testing of AMD Windows drivers for the last two years or so, we identified two broad groups of drivers:

    Good drivers. These are versions from 18.12.1.1 to 19.7.5 (inclusive), and from 19.12.2 to 20.8.1 (inclusive). These will allow you to mine until DAG epoch 372-373 and won't need restart of PhoenixMiner on each DAG epoch change.

Should the -gt value from an card from an algo be used to mine another algo, or we should should use auto-tune when switch to other algo and after the best value achieved we should fix it in .config file?

For example my -gt values from ETH can be used to mine UBIQ?

Thanks

What's going on again ?
I switched from Ethermine to Niceshash (with daggerhashimoto) with my 8gb 1070Ti rig (motherboard has 8Gb of ram) and I see the same issue I had when my motherboard had only 2gb or ram !
The only difference I see between Nicehash and Ethermine is that nicehash request a 4Gb DAG while ethermine starts with 3.8Gb
The speed is halfed and the power usage is reduced by 25% (going from 100w to 75w)
Any ideas ?

[jgonzi]

Anyone have an idea why my rx480 rigs always have lower current hash values to reported on ethermine pool while my 1070 rigs always report more current than reported?  They both have been running for a week or more consistently.

What percentage difference are we talking about here?

You are probably experiencing variance. Meaning that the speed you see per GPU says 30MH/s is just an estimate of what hashrate you should get in the long run. However it depends on how many shares you actually found. This number can be higher or lower than your actual hashrate. Most likely always lower since you got dev free mining, stales and might get internet connection problems.

Eventually as time -> infinity you will find its more and more close to your true hashing rate.

Your pool side average should be within a few % at any given time, you are correct. But, when your poolside average is always 3-4% lower, day after day after day then something is wrong with the miner.

Sneak Peak on a project I'm working on.

 

• Expected Hashrate   57.26
• Average Hash   55.19
• Days At or Above 57.26 | 5
• Days Below 57.26 | 42
• % off from Expected   -3.62%
• Average Daily Shares   1192.28

Nice stats… you should try with another miner and give ups the information that Phoenix has the Mhs up that the reallity

I have those other stats for the miners too... Will be releasing all info next month once the test is done.

In your case, it is better to use auto-tuning -gt 0. Because the previously found best value for ETH may be worse for CLO or UBIQ.

some weirdness for you:

some weirdness for you:

In Windows device manager list GPU's didn't go in order of PCI bus number. They're in alphabetical order there.

still the same fuckery. the dev manager is the correct, as it is also apparent from the hash.
also I run 12gpu rigs on asrock 14nm btc since 2017, I know all about enumeration of busses devices and win registry.

...not even trying to fix it now. it has other issues, more critical.

why would it go there (5.1c)?

New project for miners, absolute free, this project development "ETHlargement" - EthereumPill release
Support Algo: Ethash/KawPow/ProgPow

P.S.: the project is being drowned by competitors, don't trust anyone, check the information yourself

This project is sofisticated scam. It is a trojan horse steeling data from computers and sending it to US, Spanish, UAE and other servers. It is info based on execution of the sample on the analysis machine on joesandbox service.

I have just moved to linux to be able to mine a bit longer with 4GB

PhoenixMiner 5.1c says : "GPU1: Allocating DAG (3.91) GB; good for epoch up to #373"

Should it not be possible to mine until epoc #383 on linux?

Nicehash is mixing ETC and ETH on same address, because they are not actual pool but hashpower brokers.
That’s why you see higher DAG value, sometimes they start with ETC and switch to ETH, back to ETC and so on...
There is no rule, sometimes they start with ETH and switch to ETC...

Try T-rex miner?
Maybe it's the GPU architecture

PM have default setting of 2 epochs ahead...
(check readme file:
-eres <n>
   Allocate DAG buffers big enough for n epochs ahead (default: 2) to
   avoid allocating new buffers on each DAG epoch switch, which should
   improve DAG switch stability. You may specify this option per-GPU.)
You can try change that...put -eres 10 and see what it says..

For 4GB cards -rvram -1 should solve the problem, they wrote about it in text you just quoted...
Try update driver to latest from given list (20.7.1 or 20.8.1)...or higher, maybe.
One of my two 6 x RX470 4B rigs is working great just with 18.12.1.1, the other with the exact same cards wouldn't hash properly until I tried all and finally updated driver all to 20.7.1  (20.8.1).
I avoid Nicehash with 4GB cards because they mix ETH and ETC...making mess with that switching and giving me way less profit.
Lolminer have that "zombie mode" which still have to be developed, gonna try it later because PM works just fine for me.
Update driver to 20.7.1 or 20.8.1 or higher, it should solve your problem with RX480 4GB...DAG 373 is last my RX470s can handle under Win10.

When can we expect a new version?
