The  new  version  is  finally  ready.  You  can  download  PhoenixMiner  5.8c  from  here:

PhoenixMiner_5.8c_Linux.tar.gz Github


Changes in version 5.8c :

• Full LHR disable mode -lhrdis <n>  1 - yes (default), 0 - no
• Added lock core clock
• Fixed an issue causing crashing with some RTX 3060/3080/3090 cards
• Implemented new "turbo" kernels (-clkernel 3) for AMD Polaris cards that can work with the current DAG sizes over 4 GB. Note that -clkernel 3 uses double the VRAM and will
  provide slightly faster hashrate with slightly higher power consumption. You can use the -rvram command-line parameter to specify how much VRAM to be left unused
• Increased the maximum supported DAG epoch to 600 (i.e. until about Sep 2023)
• 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
• Added ROCr kernels for Vega, Radeon VII and Navi cards. With these kernels you will be able to run these cards with Linux drivers 20.45 and later but the performance will
  be lower than with the older PAL drivers and kernels. We recommend using AMD Linux driver 20.30 for all cards except RX6900/6800/6700
• Fixed an issue causing crashing with some RX6900/6800/6700 cards under Linux (there is no need to run these cards with -clkernel 0 anymore)
• Added support for AMD Windows drivers up to 21.8.1. Note that Radeon VII cards will not work with drivers 21.6.1 or higher - you need to use older drivers for proper
  operation of these cards
• Added support for AMD Linux drivers up to 21.20 (use older drivers for Vega or Radeon VII cards as they will not work with 21.20). Note that the latest 21.30 drivers are
  not supported (and the initial testing shows that even the older Polars cards are not working properly with them, so avoid 21.30 for now)
• Numerous other fixes and small improvements

Please let us know if you have any problems or questions related to PhoenixMiner 5.8c

what's the hashrate situation?

Any ongoing updates for RX 6800/6800 XT?
The miner works but only detect half of available CU (36 instead of 72)

65535

Come on, 15000!

I need BTC to go to US$ 75000 in 15 years.
Will it go that high ?

RX 5600 XT goes 40 Mh/s ethash at 90w

tag for follow
So the advise now is to keep accumulating?

Navi family is intentionally crippled by drivers, I suppose

If priced at 150 bucks, requiring 55 w for 30 Mh/s, with the current bitcoin price, the break even point would be 2 years. Much better than Navi 10's 3 years.
Hoping that BTC/USD will go to 15000 again soon

What's the guess on eth performance on the new rx 5500? My guess is similar to the 5700/XT.

The last time financial crisis occur, oil and commodity prices shoot up to the moon buoyed by the feds bailout money.
Now another financial crisis is coming, oil and commodity prices are kinda rising..
I believe bitcoin will be the next target for financial speculators to hedge the next financial crisis looming.

and now the price is back to 10200+
Moon Soon?

good for you. Maybe because I force copy PhoenixMiner 4.6c latest exe into nicehash miner plugin folder, it's not stable.

So basically we RX 5700XT users are stuck with ETHASH by Claymore now.
Using PhoenixMiner, somehow one of my two RX 5700 will crap out after sometimes and the one that is still mining will still be showing fully loaded after mining is stopped.

Anyone mining with RX 5700,
has any of you experiencing strange phenomena where only the one of the GPU is actually mining/or having its memory loaded with mining job?

what phoenix miner version?

Theoritically, you can put Four Reference cards Navi in MSI X570 Godlike. My current tower cooler blocks the first GPU slot. Waiting on 3950X before actually putting the bonus MasterLiquid AIO from MSI X570's promotions.

Anyway, I tried with three GPUS (one custom AIO cooled, two reference coolers) and it works just fine. Their temps are not catastrophic either; With fan speeds less than 50% (therefore noise is tame), the GPU temps are around 65-75 oC, with memory junction temp around 90 oC.

After 3950X is here, I will get one of that and another reference card 5700 and my goal of having four GPUs in one motherboard will be achieved.

For now the RX 5700 yiels around 48-49 Mh/S each with maximum GPU temps around 70 oC with memory temps around 90 oC, with fans running below 40 %.
This RX 5700 reference design is just great for me.

Thanks for the info.
Looks like Sapphire Pulse cooler is unable to cool down the memory chips under mining load, and the reference cooler does better job at it. Are you using custom fan speeds or left it on auto?
Also does The XT and non-XT performs the same regarding mining?

Not the VRM. In the Afterburner it's the Memory Temp. in HWINFO is the HBM temperature.
