Yes or if doing at scale, you can host in other countries where price is acceptable.

What i found out seen some guys where getting incorrect shares, this is due to timings are different in different cards.
I replicated this issue with RX5700 MSI evoke http://prntscr.com/rc2j66
To fix incorrect share issue i used 1800mhz straps
Was not able to achieve 58mh with these straps, but 55mhs at 120w from wall stable

I think it is achievable currently running 3 cards and watt meter on wall showing 470w, so it is about 140watts per card +50w cpu
What i see really strange with these timings, is that hashrate increases significantly only when i increase core clock, memory clock does very little changes. I can leave it under 920 and core 1400 they get hash 58mh/s

Cool great it worked out, im hashing quite stable. Will try to modify power usage tomorrow http://prntscr.com/rbpoh8 1 incorrect share in nearly 8 hours and 1070 valid

What speeds you where getting?
I think you might need different timings , you can try to copy 2nd last to last.

I dont have any of these gpus wouldn't be able to to tell.

I think there is bug in software , when you save it is actually edited. When you reopen , it shows edited timings but when you click on it it shows previous timing. But the saved file contains actually your edited timings. Tried this myself and replicated your problem. Did you upload edited timings to your gpu. 2nd set of timings was for me that increased performance significantly.

What GPU do you have?
Invalid shares are usually due to invalid timings on gpus , if you get them after modification.

Yeah asics will be pretty much dead soon for ETH.
Do not think ProgPow will ever happen for eth, it is taking forever.

Profit will be dead when it will reach customers.
All depends how many are releasing in market.
Also think they are not the only one manufacturing same algo miners, which will kill profit even more.

I have 10 pro .
If there is 2 bios on card save after each edit, my did not work also when edited both at once.

BIOS modded timings RX5700 - 58-50 mh/s
https://www.youtube.com/watch?v=d-AwOPJQH_4&t

Settings:
Core - 1400
mem - 930
Volt - 800

I didn't have any affect with drivers, tried Windows and HiveOS . Got same result , about 58 mhs. Check if you are uploading corect bios, and if the timings are edited. Cause the timing edit tool sometimes didn't save my room file properly.

Tested it while back, it's useless. 50% incorrect shares.

Well every card model is different , rather make your own. Dont want to brick your card...ha

Yes as there is power control tool also available, didnt have enough time to test it . But sure will update if will get some improvments.

Yes XT bios unlocks better OC to the card, seemed more stable and better speed increase.

Up until now there haven’t been any handy tools which would allow to edit AMD RX5700 graphic card bios timings. Timing editing for AMD has worked very well in past and increased mining speed by 10%. The same is possible now with RX5700 gpu. We have tested this and it is working fine, we have increased mining speed from 52-53mh/s out ff the box up to 57-59mh/s.

This is very important, even more when profitability is very low. Here are the steps we did:

Tools needed :

✔️GPU-Z – https://bit.ly/32LonaI

✔️flasher – https://bit.ly/2TlZlMl

✔️BIOS editor – https://bit.ly/2IcYNSC

✔️GPU BIOS collection – https://bit.ly/3crXCfV

So for test purpose we have had 2x RX5700 non XT version. We have edited timings and also upgraded nonXT version to XT.

Follow the steps:

Download you gpu bios to backup with gpu-z


Extract flasher to your C: drive


Download Original XT version from GPU BIOS collection


Open XToriginal.rom with BIOS editor and edit timing straps and save bios in your flasher folder. Straps edited copy 1500mhz to lower 1850…..etc (similar way as RX570 4gb cards) . These cards does have 2 bios, so edit both of them, after each time editing you need to save. This tool doesnt allow you to edit 2 bios at the same time.


Now you need to upload these to your graphic card. Open command prompt as administrator . Navigate you you flasher folder  (cd => cd flash => amdvbflash -i ) this will give you information of the gpu connected in your system.


Next you need to unlock gpu ROM to upload new BIOS type in cmd( amdvbflash -unlockrom 0 ) 1,2,3 if you have more then one gpu


Last upload new BIOS to you GPU type in cmd ( amdvbflash -p -f 0 newBIOS.rom ) newBIOS is your saved .rom file name


After flashing, the computer must be restarted. We can already admire the new data in GPU-Z. In this case I had set the boost clock a bit higher. Now the value is no longer 1925 MHz, but 2104 MHz. In real terms the card reaches 2050 MHz with the right cooling.



Easy as that, reboot your system and your hash-rate should increase. If you have done everything explained here. Other flasher versions wont work , download links provided on top of the post.

Have you measured the power usage difference . I assume it uses lot more power then if generating more heat.
Manufacturer website still only firmware V1.7
