What does the percent thing mean when it rolls off the temps and power? what does 1872% mean? I'm running 1 GPU a RX 5700XT OC 2100 on the core and 1888 memory
https://ibb.co/jZp9q28
It says
Code:
2020.08.28:20:29:41.955: main GPU1: 41C 1872% 221W


Anyone Huh Huh Huh Huh

That is % of GPU fan speed. Sometimes card give the wrong info to miner. Disregard this, it might get back to normal as it runs, it happened to me before.

Code:

Can anybody give some insight on this error?


Unsupported drivers?


I don't think so, other 5 cards in the same rig are hashing ok....
Maybe you write more about your config? Cards, system, drivers, command line? More strings from log? Before asking...


I have 6x radeon vii and today I have this error:

GPU1: Unable to set GPU clocks to 1775 MHz (Vddc 975 mv) - error -8

Temps seem ok, cclock and cvddc are low, power usage low and card is hashing at only 36 MH/s. I rebooted the system several times, checked settings but can't figure out why it happened all of a sudden.

Sapphire Pulse 5700 - 56 MH/s Hashrate - https://www.youtube.com/watch?v=mUhno8pVRhI

I tried modifying straps with Red Bios Editor but changes are not saved... when I reopen moded bios it still shows it's original values for 1750, 1800, 1875 2000 MHz.
Tried running as admin, saving with new name, overwriting but there is no change
It's XFX 5700

When you are modifying... after you change the first set of bios, are you clicking save before you go on to the next set of bios to change?  If you are not, thats what you need to do.  Example:

First set of bios straps:  Copy 1500 down thru 2000.  Click Save button... Name whatever you want to name it.

Go into second set of bios straps: Copy 1500 to everything below.  Click Save button, name this whatever you want to, just be able to distinguish the difference between this second (fully correct) version from the first one you saved.

After you have done this, use this second version to flash onto gpu.  You can delete the first version you saved, as it is obsolete. 

You have to save each bios mod each time in order for both mods to save.

Hope that makes sense.

Thanks hustleman, I followed your directions exactly but still not saved. I don't know what I'm doing wrong but I always end up with the straps from original bios.

Can you guys explain this to me.... Several times I've noticed miner is switching from DAG epoch 329 to 'Generating DAG epoch #0'. I have a mix of 1070, 1060 and 104-100 cards. My 1070 cards are doing 32+ MHs for a short time then miner is restarting with DAG epoch 329 and cards are doing about 27MHs. I understand it's slowing down with bigger DAG but what is DAG for epoch #0.

It's nicehash pool? If so - nicehash can switch on the fly between different eth forks, so it can change DAG's. DAG #0 - is one of this switches to some fork untill it give better profit.


Thanks. Yes it is nicehash. Is it just idling at that time or doing shares?

Hi, do you have experience with the Sapphire RX 5700 Pulse? I can't change the board parameters into the program (4.6c), the board seems to be locked ... especially the memory voltage locked to 0.85V (and Tmem is always approx 80°)... do you have any suggestions?

Memory voltage is locked on Navi cards, also tmem can get high u run card on high voltage, try running card on 1300mhz/750mv and put mem on 900-930, that should lower temps on card alot.

How did you get the card to run at 750mV? Mine never goes under 800mV regardless of -cvddc setting in Phoenixminer. Fan is at 70-90% all the time and power 112-118W.

I own now 2x Sapphire 5700XT.

I have used Adrenaline 1.9.2.2 and classic setting posted on this topic; -tt 62  -cclock 1300 -cvddc 800 -mclock 900 -hstats 2 it gives 52,x MH but it fails in minutes.

I have tried lower or bigger -cvvdc between 750 and 900mV, even lower/higher -tt, it fails randomly showing 0.00MH.

I tried also to keep memory stock (875MHz), it fails randomly, same problem and miner stays locked, mouse too, just hard reset works.

When I have removed -hstats 2 command, keeping just  -tt 62  -cclock 1300 -cvddc 800 -mclock 900, it worked fine 12 hours but I just tried last sollution: I have deleted all commands -tt 62  -cclock 1300 -cvddc 800 -mclock 900 -hstats 2 from ,bat file and I have used just Msi Afterburner 4.6.2 beta 2           https://www.guru3d.com/files-details/msi-afterburner-beta-download.html        wich full controls power limit, voltage and frequency, now I left voltage unattended (1187mV), GPU frequency stock, memory increased at 900MHz and power limit down to -43 or even -44%.

Works flawless.

It looks as the much commands gived to the miner (tt 62  -cclock 1300 -cvddc 800 -mclock 900 -hstats 2), especially -hstats 2,  gives driver error (atimtag.dll) and locks the miner...

So, I keept settings as in picture attached and .bat file as simple, without extra commands ex:  PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal your wallet adress.rig name, and is rock solid.

https://i.postimg.cc/RhtKXjtg/Best-settings.jpg
  It is important to avoid using both the PhoenixMiner hardware control options and third party programs (e.g. Afterburner) at the same time. While we use the AMD provided API to do most of the hardware control and monitoring, most of these programs use lower-level undocumented access and doing both at the same time can lead to driver lock ups. Note that Afterburner must be completely closed, not only minimized to tray in order to stop interacting with the GPUs. Or, alternatively, you should use only Afterburner (or other third party program) and none of PhoenixMiner hardware control options.



I tried both ways, and still would get hashrate drops to 0 mhs and a miner restart... After sometime, it would just lock the rig up. I was mining Ubiq, so there might be some issues there.... However, I did switch to Nicehash/Claymore for a test and haven't had any miner restarts/rig locks in 18 hours... I'm going to come back to PM after 24 hours and connect to NH and see how it performs.

Same here. I tried every possible combination of -tt -cvddc and -mclock for RX5700 but one card would go down to 0 Mhs followed by the second card after some time. Claymore is a bit slower but it's stable with  -cvddc 800 -cclock 1300 -mclock +910 -powlim -25,-25 -tt 58,58 settings (hashing at 50.2 - 50.5 Mhs).
I'm not using 3rd party hardware control but I also have 2 vii's and 2 1060's in the same rig which are working well with phoenix.

I have 2 RX5700, Windows 10, AMD 19.9.1 drivers and Phoenix 4.6b... I don't know how people are getting them to run at 100W, I can't get it to run reliably even at 130W. When I try to undervolt to anything bellow 1V, after few hours hashrate drops to 0.00 and needs system reboot.
Anyone else experiencing the same?

   We are running our RX5700s with the following settings: -tt 62 -cclock 1300 -cvddc 800 -mclock 900 -hstats 2 and there are no stability problems. They even run at -cvddc 750 but we want to exclude any hardware crashes when testing, so we keep the voltage slightly higher than necessary. With these settings the GPUs report power about 105W per card. Please note that is crucial to keep the temperatures low, do not use -tt above 65 as this is the edge temperature, and the junction temperatures will be higher. With good airflow, even the first generation RX5700 with the single turbine do not go above 50% fan with the above settings.


Thanks PhoenixMiner for great miner, support and quick response. I copied and pasted your settings, hopefully it runs stable. I didn't have temperature target set before which may be the cause.
Keep up the good work :-)

Patrick,
Can it change the frequency and voltage on Antminer B3?
I actually don't know, because I don't have access to this ASIC miner. Awesome Miner has a feature to change frequency (toolbar: Tools -> Antminer -> Configure Frequency), but it only works on some Antminers.

No, it can't. There is the option but it does nothing.... Miner always returns to the default 750 MHz.
$90 spent for nothing!

Re: Bitmain Launches the New Antminer B3 Miner

Unfortunately we know nothing about this version of BMMiner and Bitmain has yet to publish the source used in this firmware.
I'd be curious to know if the parameters work when passed to BMMiner directly.

PS the running cgminer, copy the launch syntax, kill the process, and then launch the miner from the CLI using the fan, fan PWM, and freq flags in line. Can't hurt to try.

I can archive the filesystem and host the gzip if anyone's interested in poking around.

Good point. Unfortunately I'm not near my miner so I can't see if the fans react to the command line at all. Frequency is ignored, at least in the GUI. Shows 750 regardless of what's being passed to bmminer.

Launch command:

Code:
/usr/bin/bmminer --version-file /usr/bin/compile_time --default-config /config/bmminer.conf -T

--help output:

Edited /etc/init.d/bmminer.sh and restarted bmminer by running the script.
Code:
3528  3527 root     S <   246m 50.7   0  9.5 /usr/bin/bmminer --version-file /usr/bin/compile_time --default-config /config/bmminer.conf --bitmain-freq 220 -T
Still hashing about the same @800 H/s and show frequency 750

Patrick,
Can it change the frequency and voltage on Antminer B3?

You can adjust the fan speeds by editing the file /config/bmminer.conf and adding these lines:

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"


That adjusts it to 50 percent the default speed

Here is the whole bracket in my current config:

}
]
,
"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-use-vil" : true,
"bitmain-freq" : "_ant_voltage=0706",
"bitmain-voltage" : "0706",
"multi-version" : "1",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"
}

My only concern with this, is any potential reason Bitmain shipped them without PWM control enabled. It’s clear that there shouldn’t be a need for this volume of air when dissipating 330W, but I’d be curious to see if the rejected share rate gets higher as the temperatures creep closer to 70+

(I don’t think BMMiner is reading HW errors in the traditional sense in this Tensority build.)

The miner seems overengineered.
Has anyone tried pushing the ASICs past 750 yet?
(The default config shows “bitmain-freq" : "750" in bmminer.conf.factory)

Either there’s headroom both ways, or the blocks on these ASICs start to bug out at higher frequencies/temperatures.

Who’s willing to figure out?  Grin

PS - Anyone else get shipping confirmation for batch 2? Seems early...

I have tried to change frequency in bmminer.conf and bmminer.conf.factory but it stays at 750.

Guyz - I tried to change speed of the fans...
This shit is screeaming like a pig in my basement and there is no need to be like that - chips have just around 45°C.

U used bitmain-fan-ctrl and pwm in SSH, but this shit doesnt made a change. It doesnt have any fan-ctrl or what?

Could somebody help?
How much temperature could this chips have?
Thinking about giving there some computer fans...


I have tried the same, adding the fan control in bmminer.conf didn't change the thing. Did you try to change the frequency? If we have to endure that loud whistlle let's get a few more hashes out of it becaus it's running cold. Mine never went over 35°C.

guuuuuys, what are now the DAILY earnings? 5 pages but none is mentioning the earnings, i just read a lot of problems with pools
