That behavior really seems to be strange. I only have one 6600 among others and it works fine with command line option for hardware settings. We will wait to see if others have clue on it.

Thanks for your reply.

The card that works fine will work fine by itself or when in a rig with other cards.
The cards that don't work as expected behave the same if they're in a rig by themselves or with other cards.
The same cards fail regardless if I specify the voltages together or individually (eg. -cvddc 800  or -cvddc 800,800,800).

I have reinstalled drivers, reset all the settings for all cards in radeon software befopre running the miner, etc etc.
It feels almost like 2 of the 3 cards have some kind of different hardware on them that regulates voltage and isn't very well supported by phoenix, but that seems pretty unlikely given they're all the same brand and it's a new card...

If you only use one of the two cards without others, will it work? And when you use PM to specify -cvddv, do you specify one value or three values such as -cvddc 800,800,800? Note that space is not allows between the numbers. It causes PM to crash when I tried it with 5700XT.

Hello, I have 3 x MSI rx6600s (non-xt) cards which are behaving strangely when I use the -cvddc command. Running under windows 10.

One of the cards will happily change voltage via phoenixminer using e.g. -cvddc 750 or -cvddc 800 or whatever. Works fine using 750, pulls about 55w which is ok.

The other 2 cards automatically crash the driver (and the card won't generate a DAG) whenever I try to set core voltage via commandline for some reason - regardless of what voltage I set. Even if it's -cvddc 800 or 900 or 1000 or 1100 or whatever (more than it should need), the 2 cards won't change voltage via phoenixminer.

Both these cards WORK FINE when you don't set voltage via phoenixminer, and you can change their voltage via the radeon software no problems.
The cards behave the same regardless of which PCI slot they're in, or whether or not they use a riser.
Same behaviour in phoenixminer 5.8b or 5.8c.
Same behaviour using either AMD drivers that support 6600 non-xt cards (21.10.2 or 21.10.3)

Does anyone have any suggestions for this issue? (other than "install linux"). Is this an issue with the driver, miner, or cards? (although if this was happening on one card I would think perhaps it's the card, but 2 out of 3 seems unlikely).

Thanks in advance for any assistance.

Here are some tips from me:

-powlim -15 I would drop this. It does not work well with AMD cards Especially when using -cvddc and -mvddc
-cclock 1200 I would lower this in the range of 1100-1150. Change slowly down until hashrate starts to drop and go 1 step up.
-cvddc 930 I would lower this in the range of 850-900. Also, change slowly.
-mclock 2050 This should be fine to go up to 2150, but it depends on the memory brand and on the GPU brand.
-tt 80 -tmax 80 -tt number must be smaller than the -tmax. With setting lower core clock and lower voltages power use and temp should drop too. So you may set -tt 70 or 75.

Also using these commands should improve hashrates:

For more options check the readme file.

I don't use Linux, but Windows and HiveOS which is a slight modification of Linux and closer to Windows. First I started mining on my RX 6700's in Windows and I got reports for the -ttj, but not for memory temp. When I switch to Hive, it started to report temp as memory temperature. So I am not sure which report is the right one.
When the dev's said, needs to be used relative values, they know better than me, but in Hive are still in use the absolute values for the voltages.
 Seems like you get the idea, so good luck in tuning it.

I am asking about Jason based API. Not the command options.

-hstats
   Level of hardware monitoring: 0 - temperature and fan speed only; 1
   - temperature, fan speed, and power; 2 - full (include core/memory
   clocks, voltages, P-states). The default is 1.

The miner log has more information like Tmem which I think is important if you want to monitor the GPU remotely. The doc says that GPU temp can be returned. How about Tmem shown in the miner log?

Alright, you are using Linux and I am using Windows.

Log says it can only do relative values.

ReleaseNotes.txt:
  - Implemented optimized kernels for AMD RX6600XT cards
  - Added support for the latest AMD Windows drivers (21.10.2, 21.10.1, 21.9.2, and 21.9.1).
  - Added support for the latest AMD Linux drivers 21.30
  - Implemented full hardware control for AMD RX6900/6800/6700 cards under Linux.
    Note that with these cards under Linux you need to specify relative core voltage:
    e.g. -cclock -50 will set the core voltage to be 50 mV under the default value

Apparently it also counts for -cvddc

Hello,

I just restarted some miners after long time.
I am using 5.5c on 580 8Gb since later versions gave me errors. They are all around 29/31 Mh, can I squeeze some more hashes ?

Also one 580 is a 4Gb, so I am mining ETC, but the Mhs is around 15 Mhs, I remember it suppose to be around 29.
There are the settings I am using:
-proto 2 -coin etc -cdm 0 -stales 0 -worker AMD5804G -gpus 1 -amd -acm -astats 1 -astats 1 -leaveoc -mi 14 -gt 40 -gser 2 -wdog 1 -tt 80 -tmax 80 -fanmin 70 -fanmax 85 -powlim -15 -cclock 1200 -mclock 2050 -cvddc 930 -mvddc 960 -log 0

Also -tmax 80 not working, it sets it to 84 default.

Am I missing something from when I was mining with version 3.0 ?

thx

In my case, 6600 non-xt, PM takes the absolute value. The log shows below. I have "-cvddc 900" in config.txt

set GPU clocks to 1100 MHz (Vddc 900 mV)

What the log shows if you use absolute value for 6600xt?

Depending on your payout choice default you get paid when you reach 0.1 eth and with 1 GPU it will take a while depending on your hashrate.
For me with an avg. of 61MH/s it takes me abt 90 days now
My last payout was on 15 sept. and I am now on 52%.

Here's my command line:

PhoenixMiner.exe -pool ssl://eu1.ethermine.org:5555 -pool2 ssl://us1.ethermine.org:5555 -wal ########################################## -coin eth

What pool are you mining too?

Coinbase is an exchange not a pool.

The pool you are mining on determines minimum payout.

I'm a newbie, I'll admit it. I just have 1 GPU running right now is all but will be adding more. I'm pointed to ETH as my coin...when do I get paid for what I have mine? I'm pointing to Coinbase if that helps.

Yes it is probably for all 6000 cards. It is mentioned in either the readme.txt or the releasenotes.txt somewhere at the beginning. I also tried the absolute settings first but PM would nnot pick it up so I started to read the readme and releaenotes a bit better, what I should have done first 
If you don't use a relative value it will say so in the phoenixminer terminal window. When you set it a restart is needed as it cannot do it on the fly like with some other settings.

I use absolute value for all of my 5700XT cards and 6600. Is this special for 6600xt? The API help says "Set GPU core voltage in mV (0 for default)" and doesn't mention the relative value. May it works also.

Actually the RX 6600 XT does report the ttj and I have set it -ttj 65 and PM reports the Tj 64C so it seems to work, at least on my card.
I'll play around with your suggested settings to find some improvements.
My settings now:
-cclock 2490
-cvddc -100 - Apparently you have to set it to relative values.
-mclock 1020
MH/s 29.565 at the moment, so a slight improvement 

That was before your suggested settings, thx
