I have small drop (1-2%) in hashrate on RX570 after switching to 4.5b from 4.2c.
Is that normal ?
no it's not ok.
but I'm fine on gtx 1070

Maybe speed drop on old drivers? I use RX 580 8Gb on latest driver. Speed is the same as on 4.2c with 19.4.3. driver.

The first beta of 4.5 is finally here. We tried to delay it until the RX5700 kernels were ready but there seems to be some kind of bottleneck on these cards and we haven't figured out how to work around it yet. You can download PhoenixMiner 4.5b from here:

Is there a plan to support -tt on linux for the final version of 4.5?

  No, most probably scam. The only official place to download the miner is in this thread. If you got the miner from another source, we provide the checksums of the archives for each version here so you can check if the miner was tampered with.

  Go away, troll. We have kernels for Navi - RDNA isn't that different from GCN. The problem is that the GPUs are "locked down" for ethash mining by either limiting the number of TLB entries, or lowering the page size. This may be unintentional but we suspect that it is by design, probably to prevent miners from buying out all Navi GPUs and leaving the gamers with high prices and low availability. RX5700 is the first very competitive AMD gaming GPU since Polaris, so they probably want to win some market share as far as gaming market goes. We hope that this is not hardware limitation and a future driver will remove it but only time will tell.

   With the current no-so-great mining profitability, they really didn't have to do this but it's absolutely their choice, and with the current prices of Polaris, it is still one of the best cards for ethash mining. If the Navi cards weren't locked down, they would achieve hashrate in the 50 MH/s ballpark. We are still working on some kind of workaround but it doesn't look good at this moment.

Dear PhoenixMiner,
Any plan with rxboots same claymore?
  We are considering it but you can achieve the same with AMD Memory Tweak -ref option.


Phoenix miner 4.5b work very fine with HIVEOS...but....why new 4.5b "eating" more electric power then 4.2c?
  We didn't notice any changes in power consumption in our testing. Please let us know what GPUs you are using and what is the change in power consumption.


In the 4.5b version of the program, the hashrate is lower than in the 4.2c
low hashrate with RX 570 / 580, with modded bios - 25 MH/s
on  4.2c - 30 MH/s!
I have small drop (1-2%) in hashrate on RX570 after switching to 4.5b from 4.2c.
Is that normal ?
  There are no changes in AMD kernels for this version. However, there are two possible reasons for this behavior:
  • The hardware control for AMD cards is now more robust. It wasn't working that well with many driver versions because AMD have changed the API many times in the last year or so, and even removed the driver/VBIOS based target temperature controlled fan option entirely. So we implemented more robust control of the fans and temperatures. Most probably you cards were "overshooting" the target temperature or the maximum fan speed with the old version but 4.5b will enforce these limits more strictly. If you have -tt 63 and -tmax 65, as soon as GPU reach 64-65 C it will start to throttle down to avoid overheating. You need to either increase the target temperature (-tt), the maximum temperature (-tmax), or increase the max fan speed (-fanmax) to avoid throttling. A good way to check which of your cards are throttling is to add the new -hstats 2 option and check the core clocks - if they are lower than the ones you have specified via -cclock, you need to either increase -fanmax, -tt, or -tmax
  • The new -mt option is nowhere near that good as good modded VBIOS (or good memory timing applied by AMD Memory Tweak). So, if you have modded VBIOS or are using another way to set memory timings, avoid the -mt option. It is intended only as a last resort, quick and dirty method of increasing performance on non-modded cards. Also, avoid changing the -mt option while the miner is running (by changing config.txt and then reloading it with the c key in the miner console) because this frequently leads to crashes.

  Please let us know the GPUs you are using and what is the difference of the hashrate. Is it only on some GPUs or it is the same across all GPUs?


Is there a plan to support -tt on linux for the final version of 4.5?
 Yes, we are currently working on it (for AMD cards) but it may take a few weeks and be released as part of 4.6 (it will be out relatively quickly, as we are moving to faster release cycle to follow the frequent driver releases from AMD).

@PhoenixMiner
Are you planning to add memory straps/timings for Nvidia cards?
I don't like claymore (compared to yours)
but was forced to switch because of nvidia memory timings (gives a lot more of hash rate)
(which is a big advantage)

@phoenix correct me if I'm wrong but isn't 5700 already limited with memory bandwidth and theoreticall speed for them is 37mhs for non xt and 50mhs for 5700xt?

In the 4.5b version of the program, the hashrate is lower than in the 4.2c
I have the same hashrate, which is on 4.2c, which is on 4.5b, but on drivers version 18.6.1
On version 19.7.1, the speed is 20-30 hashes lower
Seriously, 20-30 HASHES lower? What mean 20-30 hashes on 30+ Megahashes?
On so big driver difference I recommend to make new autotune -gt parameter... Maybe you recieve 20-30 hashes more...

All those limitations can be worked around in linux easily if thats the only issue preventing ethash from working properly.

i use rx 570 with driver "Adrenalin Edition" 18.5.1.
  We have retested RX570 under both older and latest AMD Windows drivers and there is no performance decrease between 4.2c and 4.5b. Please check if your cards are throttling (use -hstats 2 as explained in our previous post) because 4.5b enforces the -tt, and -fanmax parameters more strictly than 4.2c. Also, don't use -mt if you have modded your cards or are using other means to change the memory timings.

@PhoenixMiner
Are you planning to add memory straps/timings for Nvidia cards?
I don't like claymore (compared to yours)
but was forced to switch because of nvidia memory timings (gives a lot more of hash rate)
(which is a big advantage)
  We are considering this for the next release but there are some concerns with long-term stability and (probably not very likely) possible DRAM overheating with these aggressive timings.


I have the same hashrate, which is on 4.2c, which is on 4.5b, but on drivers version 18.6.1
On version 19.7.1, the speed is 20-30 hashes lower
  If you are getting lower hashrate from 4.5b on drivers ver. 19.7.1, you definitely need to rerun auto-tuning (press z in the miner console or run the miner without the -gt option). 4.2c doesn't support the most optimized kernels on drivers 19.7.1, and its optimal -gt values are very different than these of the optimized kernels.


I keep seeing everyone mentioning 4.5b, yet I don't see the link on this forum. I am going
to assume it is not a legit release?
  It is a beta version but it is legit. We don't put it in the first post to keep it clear that it is not the stable release yet. You can find the relevant post here: https://bitcointalk.org/index.php?topic=2647654.msg51874428#msg51874428


@phoenix correct me if I'm wrong but isn't 5700 already limited with memory bandwidth and theoreticall speed for them is 37mhs for non xt and 50mhs for 5700xt?
  No, both 5700 and 5700 XT could do about 50 MH/s without the TLB entry count/page size problem. That much is certain from our tests. Why exactly there is such limitation is just a wild speculation on our part as well as when (or if) it will be removed.


...
   With the current no-so-great mining profitability, they really didn't have to do this but it's absolutely their choice, and with the current prices of Polaris, it is still one of the best cards for ethash mining. If the Navi cards weren't locked down, they would achieve hashrate in the 50 MH/s ballpark. We are still working on some kind of workaround but it doesn't look good at this moment.

All those limitations can be worked around in linux easily if thats the only issue preventing ethash from working properly.
  Hope so but it may not be that simple. It is not that hard to implement practically unbreakable scheme where the GPU can be "unlocked" only if you know the right keys. Once again the whole thing is wild speculation on our part based mainly on the fact that it seems very implausible no one in AMD tested the Navi in ethash given than this is one of the main applications of their GPUs.

thanks for your great work @phoenixminer

would u mind to give an example on how to use the new options?

thanks and regards




  • Added hardware control and monitoring (clocks, voltages, fans, etc.) for Nvidia cards under Windows. Note that you should specify the clocks for Nvidia cards relative to the defaults (e.g. -mclock +400 instead of -mclock 4400)
  • Added hardware control and monitoring (clocks, voltages, fans, etc.) for Radeon VII cards (Windows only)
  • Added advanced hardware monitoring (specify -hstats 2 to activate it). It will show you the GPU core and memory clocks, voltages, and P-states (if supported)
  • Added GPU power consumption if the driver reports it. You can also specify the idle power (-pidle), PSU/GPU efficiency (-ppf) and electricity cost (-prate) and have the miner calculate the daily electricity costs for you. If you are using third-party mining software which doesn't expect the power consumption figures in the miner's log, you can disable it by specifying -hstats 0
  • Added new parameter -mt to set the memory timings on AMD cards. -mt 0 is the default, which uses the VBIOS memory timings. -mt 1, and -mt 2 use predefined memory timings that are independent from the VBIOS timings. This option is useful for mining with RX580/570/560/480/470/460 cards without modding the VBIOS. This works only on Windows and with relatively recent drivers (from the last 6-8 months)
  • The bench mode now works for dual mining and ProgPOW. The algorithm is determined by the -coin and -dcoin parameters. E.g. -bench 10 -coin bci will bench the BCI ProgPOW, and -bench 10 -dcoin blake2s will bench the dual mining

hello, i just found a big bug on your miner

when a mining rig for any reason looses the internet conection about 10 min to an hour, the system should make some switches the pool, because the miner, has not internet conection, it thinks that the mining pool is down, and changes to the next configuated pool in the bat file, or in my case that i am using ETHos the local.conf configuration file, for example

i am minig etc on the server ssl://us1-etc.ethermine.org:5555 and the failover is ssl://eu1-etc.ethermine.org:5555

So, the miner looses the internet conection on the main pool it thinks that the first server is down and switches to the second, and backwards, over and over and over again, and at the end, the miner switches to the DevFee pool, and stays there, when the internet conection is restablished, the miner mines locked in the DevFee account, you can see in the ETHos panel the rigs are running normally, but in the minig pools, all rigs using Phoenixminer are down, and it has happend to me in the last few months that i am using the miner, that somethimes, my internet conection fails after midnight and when i wake up in the morning all my rigs apparently are working fine according to the ethos panel, but on the pool side, they're down several hours ago, i found a solution on my side, and it has worked for me, but i'd love that the dev would contact me and see what we can do, from my part i disabled the devfee mining by code on the miner, but it would be great if the dev could repair the bug and mine again paying the devfee  to @phoenixminer that he deserves for an excelent miner that he has created

@PhoenixMiner, you said:

...
  • Increased the maximum supported DAG epoch to 450. Note that AMD drivers don't allow buffers larger than 4 GB so the biggest possible DAG epoch with current AMD drivers is 378
...

So... Are all 4+ Gb AMD cards (even Radeon VII) become usless, when we reach epoch 378? If AMD didn't fix drivers...
Please, correct me if I wrong.
