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

[bategojko74]

I'm currently using a Vega 56 with 18.5.1 drivers on Win 10 x64 OS.
Within every 24-48 hours the miner (4.1c) crashes and also crashes Windows.

The card operates at a rather moderate OC: -gt 16 -cclock 1000 -mclock 950 -cvddc 900 -mvddc 800 -powlim -25.
Is there anything I can do to improve stability besides losing the OC?
Anyone else some experience with stabilizing 56s by any chance?

Lower the temperature: -tt 54

Really, you think/know that helps (coming from -tt 60)? Seems pretty low to me, but I'll give it a shot, thanks!

This (-tt 60) is the temperature of the GPU Cores. The temperature of the GPU Memory is unknown and higher than this (especially for Vegas where the memory is stacked over the GPU cores), because ETHASH algorithm is extremely memory intensive.

People usually overclock Vega64's memory from 945MHZ to 1100MHz which makes 16.4%
You have overclocked your Vega56's memory from 780MHz or 800MHz to 950MHz which makes 21.8% or 18.8%. It seems to me too much.
Maybe you should try -mclock 908 (for 780MHz base memory frequency) or -mclock 930 (for 800MHz base memory frequency).

On the previous page of the thread Soliqesh offered the following settings for Vega64:
Vega64 - Strix
OverdriveNtool
Core - P7 852/825mv
Memory - P3 1083/825mv

Check also here how people mine with Vegas. Maybe the lower memory frequencies (800 MHz) are for Vega56:

There is a performance loss with new version on R9 Fury cards: its only 28M\s now, when it used to be 30M\s, power consumption also dropped by 5-7Wt. Had to roll back to 4.0b.

Did you changed -gt parameter? Use auto-tune process.

I have -gt parameter set in config.

upd. as it turned out with new version of miner optimal -gt value has changed, it used to be 138, now its 187. So hashrate became the same.

That's what I wrote about...

P.S. Phoenix, when we can wait 4.2 version?

Hi all i have probleme with new version phoenix . With old version on all my r9 290 Trix i have 28  29 mh/s and now i have only 23 mh/s if a member have same probleme and he have resolve whrit here please . Thanks for your help .

What driver are you using?
What OS?
Did you let the auto tun run?
Did you change any settings after the last auto tune was run?

What best driver for amd rx570 4gb?
Thank!

      The Hawaii (AMD 290/390) kernels in the latest version are actually even slightly faster in our testing. Unfortunately the 290/390 cards are also susceptible to the DAG-size related hashrate slowdown, so your hashrate will be quite a bit lower if you mine ETH or ETC, which both have DAG size approaching 3 GB. This has nothing to do with the amount of VRAM in the card but with other things (TLB size and page frame size), which can't be changed via the driver as with Polaris cards (4x0/5x0). You should try mining a coin with low DAG size (for example DBIX, Pirl, etc) and will see the same hashrate as before.

   If you are not mining ETH or ETC and still seeing lower hashrate, please check the following:
      - remove the -gt parameter to allow PhoenixMiner to find the new optimal -gt value (it can be different than before)
      - check if the card is not overheating or if the power limit is not too low

P.S. Phoenix, when we can wait 4.2 version?

  A few weeks. We are waiting to be sure that Radeon VII kernels will work properly (the cards are still not here and won't be for another week), as well for some stability tests for the new hardware control features for AMD and Nvidia cards.

   Avoid the latest drivers as they aren't properly supported by PhoenixMiner, otherwise there is not much difference between all 18.x.x drivers. We found 18.5.1  to be most stable for us.

Too long wait... Maybe you can release 4.1 version with AMD newest drivers support?

Hi, I was wondering if it would be possible to get REOSC as an alternative ethash for devfee,  I have had to stop using PhoenixMiner on a few older rigs because of the ETH and ETC Dag size being too large and is now unsupported.  I really like the software and would love to be using it once again.  I know of many miners with this similar issue while mining REOSC.  REOSC is a fairly new coin but is an up and coming project with many incentives for savings including Masternodes and accruals on various quantities of deposits.

Can you add support for Enegi coin? It seems to be a variant of Ethash

[demion90]

-gpow resets to 100% after devfee. 4.1c Windows 10 x64 1607 Nvidia 418.81.

update:

-mi 0 does not decrease intensity low enough (-ethi 0-2 claymore is decreasing enough though).
-li 1 not suitable at all usage jumping from low to 100% all the time.

-mi 0 and -gpow 90 works perfectly but resets to 100% usage after devfee.

do you think faster "turbo" kernels will speed up hashing on Vega as well ? Currently turbo kernel is disabled for vega.

   We will try to release an alpha version this week (maybe missing a lot of the new features but at least we will get feedback on what is ready).

    We will try to add support for it but in the meantime you can also force another coin for devfee with low DAG size like DBIX (add -coin dbix to your command line or COIN: dbix to the pool line in epools.txt).

    It's definitely in our TODO list but things like ProgPOW are with higher priority.

-gpow resets to 100% after devfee. 4.1c Windows 10 x64 1607 Nvidia 418.81.

    Thank you for reporting this. We will try to reproduce it and fix it for the upcoming release of PhoenixMiner.

   Unfortunately because of the way memory controller on Vega works, there is no increase of hashrate with this optimization.

Hi, I have problem with PhoenixMiner 4.1c and ethproxy - error Stratum thread not responsive for 51 s disable.

with PhoenixMiner 4.0b everythings work fine.

Any idea when is a problem?
thx

Since Radeon VII is based on Vega, does that rule out using it's 16GB for a turbo? Theoretical question for now, since almost nobody has Radeon VII

[Phantas]

yes, try 

[UnclWish]

its really better than Claymore?

Only if your drivers supported by miner. Claymore didn't have this dependence. But if Phoenix miner support your drivers - it faster.
