Thanks a lot, guys!

I'm running with my GPU fans around 52-55% on every 3070 in 4 rigs depends on what manufacturer the car has.
Every and each card has the corresponding distance to have good ventilation, plus supporting them with some external fans.

I was just curious about the fan's percentage.

Hi there,

Can someone describe to me, please that which is better for the GPU when 24/7 mining rigs?
I'm using external fans also to have the whole rig cold, but I'm curious about it

- higher fans rpm with lower gpu + vrm temp
or
- higher temp with lower fans settings?

What is the highest RPM for GPU fans which could be stable and not harmful for a long time?

Hey guys

(mining ethereum, ethermine pool)

I'm just switched from Phoenixminer to T-Rex (on every rig) can someone help me how can I display the actual share difficulty as Phoenixminer does?

Are there any recommended commands to use (like some plus information about the GPU-s)?

Thanks for your answer in advance!

Yup, I see what you mean... But I'm not a fan of Linux as I'm not a noobie with that command line things.

I'm coming from Mac OS which's my daily worker. Windows is just easy to use for me & afterburner as I know a lot of them from my childhood.

Thanks a lot guys!
I will give it a try to both of them.

Should I change the pool too? Or stick with the ethermine pool? 

Hey there,

I'm here to ask for your kind help, please. I have some 6 GPU rigs with 3070 cards, some of them with different brands some of them are the same ones.
ETH mining, ethermine pool, phoenixminer.

Everything works quite well for a day or two. (like 13-15.000shares for the whole rig, 3-4000/GPU. )
Then suddenly some GPUs in separate rig starts to get incorrect shares...
A ratio like 4-5000 / 300 invalid for one or two cards in the same rig the other ones working well.

Up-to-date Windows 10 pro on every, with the latest Phoenixminer 5.5c.

GPU's undervolted with afterburner (46-54% - depends on the actual GPU) + memory oc (950-1000).
Monitoring with HWinfo, GPU-D.

Tried 'solutions' what I have found on this forum but still not working:
- Revert the GPU to stock settings, not worked still invalid shares...
- Restarting the whole rig, working for 1-2 days then some cards starting to get invalid shares again.
- After a restart, delay the afterburner until Phoenixminer boots up well.
- Changing the risers in the whole rig...

Should I change to a different mining software & pool? or any other ideas, please?

I'm just getting confused have no idea what to do but gonna stay on windows.


At least, a question for the end just how can I identify which GPU is which in the Phoenixminer/HWinfo as it is not in the same order as on the motherboards (in that case I have 6 GPU-s in the same rig).

Thanks for your help in advance!
