PROBLEM! Claymore OK, lolminer OK, TeamRedMiner OK ale PM 5.2d KO...
Please do something from the SW to be able to benefit on the RX 570 8GB. How come other SWs go?
.....
2020.11.18:10:21:04.955: main OpenCL driver version: 17.8-BETA
....

Currently the big DAG buffer, which is required by the latest ETH and ETC DAG size, is not supported by the AMD BETA blockchain driver, which is quite old. We will try to make it work but don't hold your breath - your best option is to upgrade to new drivers, for example 20.4.2.

The -mvddc doesnt work

If i put 800, HWiNFO64 shows me 850, and if i put 820,830,... al time HWiNFO64 shows 850.

Any idea? Im using 5.2c with AMD driver ver 19.12.2 (rig of 5700 xt)

The driver allows controlling the voltages only within certain limits. Try to set ti to 860 to see if it can be controlled at all with this driver. If it is successfully set to 860, then 850 mV is the minimum possible to be set via the driver. If you can't even set 860 mV successfully, then you may try to use newer driver, or third party tool for undervolting the memory.

I have the same problems with 8 GB Cards ... they do not work at all with the new version !

Which driver version?

Quote from: bluspirit on November 18, 2020, 12:18:59 PM

RX 580 4GB - 20.4.2 drivers - Win 10 (1709)

@epoch 375 - PM 5.2c 31.7 MH/s (stable)
@epoch 376 - PM 5.2c 28.8 MH/s (stable)
@epoch 376 - PM 5.2d 29.8 MH/s (in testing)

I'm still using PM 5.1c for 8GB cards, stable so far.

Thanks PM

As long as you stay on driver 20.4.2, 8GB cards will work until epoch 390, after that you need to upgrade to PhoenixMiner 5.2d or later.

@PhoenixMiner, AMD released 20.11.2 driver. PM 5.2c didn't support it. It's need update.

It will be supported in 5.2e. But unless you managed to get RX6800, there is no need to use the latest driver.

guys can we set some target temp here with new drivers? Newest overdriventool we can´t set an target temp, thats why im asking if can put it here ?
Don t want an fixed fan speed but an target temp

-tt <n>
Set fan control target temperature (special values: 0 - no HW
monitoring on ALL cards, 1-4 - only monitoring on all cards with
30-120 seconds interval, negative - fixed fan speed at n %)

Yes, should be working with all drivers from the last year or so. You can also use -ttli to set the temperature at which the miner will start lowering speed if the fans can't keep the temperature set with -tt. Example: -tt 63 -ttli 67 -fanmax 60 : the miner will try to keep the temperature at 63C, but without setting the fans above 60%. If the temperature continues to climb, at 67C, the miner will start reducing hashrate just enough to keep the temperature around 67C. NOTE: In the newer drivers, -tmax no longer works, so use -ttli instead

Same version 5.2C and 5.2.D, cause concern with my RX580 8GB cards, I lose MH/S even with daglimit XXXX

I reverted to 5.1C is no longer a problem.

Can you tell us the driver version and what are you mining (ETH or ETC)? We can't detect any loss of hashrate on 8GB cards in our internal testing.

Hi

I cant set my max temp for throttling purposes. it shows in phoenix miner cannot set max temp .
I have closed MSI AB. still does it. I need to throttle i am in a hot climate.
this has happened since I updated the drivers for 5.2d

Yes, -tmax no longer works on the newer drivers. You can use -ttli instead - it sets the temperature at which the miner will start lowering speed if the fans can't keep the temperature set with -tt. Example: -tt 63 -ttli 67 -fanmax 60 : the miner will try to keep the temperature at 63C, but without setting the fans above 60%. If the temperature continues to climb, at 67C, the miner will start reducing hashrate just enough to keep the temperature around 67C

Thanks for great help as usually
