Re: PhoenixMiner 3.0c: fastest Ethereum/Ethash miner with lowest devfee (Windows)

Hey All,

Just switched from Claymore 11.9, so hoping things are more stable now.

I'm running Windows 10 (1709) AMD RX480 Nitro+ 8Gb Samsung Cards using 18.2.1 driver and latest Phoenix Miner 3.0c

But am a little perplexed, when setting -tt 59 in the cmd line, it does not seem to adhere to it and most cards are over this setting around 64 with fanspeed around 40%


Why?

Instead of -tt 59, try -tt -50, it will set fixed fan speed to 50% and you will get lower temperatures.
You can also increase it if that doesn't give you gpu temperature you wanted.

According to the Readme -tt xx is Set fan control target temperature

From using Claymore this is just set the temp I want the GPU's to run at? I.E -tt 59 and the fan control will do the rest. Am I mistaken?

The setting you are referring to I think is -fanmin

Does not help with all this hot weather, I'm having to shutdown my miners as they can't cope.



-tt [number] = target temperature (auto adjusting fan speed to match temp)
-tt -[number] = fan speed (static fan speed)

Re: PLEASE HELP!!! 6 GPUs detected but only 4 are working

Hi, I am having this problem now for weeks and I haven't found any solution.

When I run the miner it detects all my 6 GPUs.

But then when the miner starts it only detects 4.
I've seen this error and I don't know how to fix the issue.

I've already tried uninstalling and reinstalling drivers but still the same.
I also uninstalled each card and put it one by one. Still nothing changed

Any help would be much appreciated.

Hi, could you paste entire bat/config?
Virtual memory/page set to 24+ GB?
Does it work with Claymore?

Thanks for replying! Really do appreciate the time taken, and help offered =) Response below


I'm not familiar with Radeon mining, but from the error message, I think it is pretty obvious that there's a memory problem. Your graphic cards seem to have enough RAM (4Gb should be enough). Another thing you should check is virtual memory. Have you checked your virtual memory (Page Size), maybe there lies the problem?

As stated in my post, I have tried upping from 24000-32000 MB paging file to 32000 - 48000 MB. No difference.
Yes, I think there is some issue with maybe the motherboard, as the same error is for all cards in the rig, and isn't really anything pointing to this being a software issue.

The error message is pretty descriptive as it and all you have to do is as it says, "check your drivers."

If you really already tried DDU and reinstallation of latest drivers, I would recommend using the Aug. 23 AMD Blockchain Drivers. They should still be available for download online as they are pretty popular for their stability and use in mining.

Also, did you update your windows 10 OS recently? That latest update screwed up everything. Google ethermining and win10 update errors.

I really have tried DDU, and reinstalled drivers. Both new and old. Trying the blockchain driver now, haven't yet because 1. Newest worked fine before this issue, and 2. I have 10 cards in the rig, and the blockchain driver only supports up to 8 GPUs.
Win10 is not updated (disabled updates), and is sitting on version 1709.. this same setup, and versions works across all rigs I own.

Help needed! 4GB GPUs can't be mined on?

Hi,

New user on the forum, thanks for having me =)

Having a weird issue with one of my rigs - see image #1 below
PhoenixMiner/Claymore it seems to show the same issue, but Claymore has more information, see image #2, tokenminer even more (see error text in bottom of post)
Seems to do with the miner not being able to save DAG to GPU memory? Maybe not purged after previous session?
10x 4GB RX570s, the machine has 8GB of RAM.
Running  Win10 with latest driver.
Tested with Claymore, Phoenix, tokenminer, ethminer - Clearly not a miner issue
Testet reinstall driver (with DDU), reboots and increase of swap file to 32GB+.

Anyone seen this before?

In tokenminer: No GPU device with sufficient memory was found. You may need to change the --opencl-platform argument to 1. (this changes nothing BTW)

Hi,

New user on the forum, long time PhoenixMiner user
Having a weird issue with one of my rigs - see image #1
Rig has been working fine up until now. It had the issue yesterday, but it fixed itself after a reboot.
In Claymore it seems to show the same issue, but with more information, see image #2
Seems to do with the miner not being able to save DAG to GPU memory? Maybe not purged after previous session?

EDIT:
Could it be because the rig is running 4GB of RAM?? (4GB is working flawlessly on 8 other rigs with 8x GPU setup, this has 10x)
Update: No, 8GB internal RAM gives same result.
