Hi all, my mining rig is back to life after 2 years...

Hardware:
ASRock H110 Pro BTC+ (Bios 1.60)
2 x Corsair HX1000
6 x Radeon RX 580 8GB (modded Bios)
6 x Radeon RX 470 4GB (modded Bios)

Software:
Windows 10 20H2 19042.685 (the latest)
AMD Radeon Software Adrenalin 2020 Edition 20.12.1
PhoenixMiner 5.4c
ATIkmdag-patcher 1.4.9

Settings:
64GB Allocated Memory in Windows 10 (PheonixMiner asks to allocate minimum 42GB+ for 12 cards, I allocated 64GB).
All cards RX 470 & RX 580 are modded (bios) + atikmdag-patcher for drivers.
AMD Radeon software -> every card has been switched from 'Graphics' to "Compute" mode.

I am running 12 cards at the moment and everything is stable but I have VERY LOW hashrate on all RX 470 4GB between 6-9MH/s.
I restored original bioses on all RX 470's and run miner without RX 580's - hashrate was 8MH/s on all cards.

Is it time for selling RX 470 4GB cards, or am I doing something wrong??

Can you add support fo 12+ GPU's?

It is working but I can turn on/off cards 11,12+ (only 0-9).
You can change it to two digits 00-99 or 0-9, a-z.
I can't see temperature and most options doesn't work (OC, Power Level etc).

BTW, MSI Afterburner also doesn't support 12+ GPU's (it can support 7 or 8 GPU's).

I don't know... this is why I'm posting it.

I disabled GPU0, GPU2, GPU3, GPU4 and GPU5 on Claymore's miner and I still get 35.1MH/s on GPU1.

After 30 minutes I compared the miner hashrate to pool hashrate, and guess what? It is the same 35.1MH/s!

6x RX 470 4GB = 210MH/s
"Current developer fee is 1%" - sorry Mr Claymore, but I do not believe it.

1. I have a "Magic" RX 470 card
2. I created a "Magic" BIOS MOD (but it works on one card)
3. There is a bug in Claymore's miner and one of my card shows "real" hashrate.

What do you think about it?

I think there is something wrong with Ethereum and Claymore's miner...

PLEASE NOTE THAT THIS IS ONLY MY CONSPIRACY THEORY, AND I COULD BE WRONG!

1. What if Claymore is a programmer from Ethereum team?
- He or they can create the most efficient Ethereum miner closed-source software.

2. What if he or they hide the real hash rate and get more than 1% developer fee?
- I have proof of this, one of my cheapest Sapphire RX 470 4GB (from Overclockers UK - £150 on Black Friday) has 35.15MH/s and NO REJECTED SHARES!

Using the same server with the same cards  I should get 27.75MH/s on every card, but on one I get 35.15MH/s (working for 43 hours!)
If this is true, one person or group can receive not 1% but 21% of our Ethereum AND THIS IS FRAUD ON A GLOBAL SCALE!!!

My screenshot, I can upload a video on YouTube...

More coming soon on my website www.FirstEver.eu and my Youtube channel...

I do not agree, tell my why MSI Afterburner can detect the card order... ?
You can use a different Windows system or drivers but the card order is ALWAYS THE SAME.

For ASRock H81 Pro BTC:

PCIE1 - GPU2
PCIE2 - GPU1
PCIE3 - GPU3
PCIE4 - GPU4
PCIE5 - GPU5
PCIE6 - GPU6

You can check it on your miner.

1. Run MSI Afterburner
2. Unlink the same GPU's settings
3. Change the fan speed to 100% and check the card number

This is a NIGHTMARE!

Do you have the same problem as me?

Correction - H81, not G81

NiceHash EQM Zcash 1.0.1b / GTX 1070 @ 2050/8900 = 130 Sols/s
NiceHash EQM Zcash 1.0.1b / i7-3930K @ 4.5GHz = 18 Sols/s
NiceHash EQM Zcash 1.0.1b / GTX 1070 @ 2050/8900 + i7-3930K @ 4.5GHz = 148 Sols/s

NiceHash nheqminer 0.4b / GTX 1070 @ 2050/8900 = 35 Sols/s
NiceHash nheqminer 0.4b / i7-3930K @ 4.5GHz = 29.5 Sols/s
NiceHash nheqminer 0.4b / GTX 1070 @ 2050/8900 + i7-3930K @ 4.5GHz = 64 Sols/s

Claymore's ZCash 6.0 / Radeon R9 290X = 146-152 Sols/s (6x 290X = 880-915 Sols/s)

6x Radeon R9 290X (1150/1350MHz) GPU/MEM
AMD Crimson 15.12 - Windows 10

Claymore 1.2 Beta - 194.8MH/s (Stable)
Claymore 3.2 Beta - 195.6MH/s (Crash after 1 day)

How many cards did you have?
For more than 4 GPUS use the latest drivers from Windows Update.
If you're using 1-4  GPUS try to install Catalyst 14.7 RC:
http://support.amd.com/en-us/kb-articles/Pages/latest-catalyst-windows-beta.aspx

And try this settings:


Don't forget to add this lines in your *.bat


On the end... you can try to overclock your GPU core at 1050-1150MHz (HW must be 0).

Something is wrong here... I am not reaching 20Mh/s so where is my 9.4% or 1.68Mh/s? (17.76Mh/s vs 16.08MH/s)

I have 2 RIGS and always the same Hash Rate per GPU = 2.2Mh/s (X15)

My specs:
Rig 1: 4x MSI Radeon HD 7990 (underclocked @ 950MHz, undervolted @ 1.1
Rig 2: 3x MSI Radeon HD 7990 (underclocked @ 950MHz, undervolted @ 1.1
Windows 8.1 Update 1 and the latest drivers from Windows Udpate 13.251.9001.1001 (2014/07/04)

Test 1 - Maxminer.net or Suprnova.cc @ Rig 1 (8GPUs)

• sgminer 4.2.2 (build 2014-07-20): 1.990Mh/s / GPU
• sgminer 4.2.1 (build 2014-06-25): 1.840Mh/s / GPU

Result: The latest version of sgminer 4.2.2 is 7.5% faster than sgminer 4.2.1 build (2014-06-25) but still 9.4% slower than original speed 2.2MH/s.

Test 2 - Maxminer.net or Suprnova.cc @ Rig 2 (6GPUs)

• sgminer 4.2.2 (build 2014-07-20): 2.010Mh/s / GPU
• sgminer 4.2.1 (build 2014-06-25): 2.220Mh/s / GPU

Result: The latest version of sgminer 4.2.2 is 9.4% slower than sgminer 4.2.1 build (2014-06-25).

0.00000001 BTC after coin dump

One card (2GPU's) = 2x 129.5MH/s = 259MH/s
I'm using underclocked/undervolted cards ... (95%)

What is your hashrate?

Hi guys! I have 2 RIGS (7x Radeon HD 7990) = total 1.8GH/s

• Max temperature: 70'C
• Rejected Shares: 0.01%
• Hardware Errors: Always 0!
• Location: London, UK

Who want to rent it for 0.05BTC/day?

BTW
Luffa-512 use 25% power (Watt) than X13/X15 algorithm

No, "Initial Revenue / 1MH/s  / Day" has wrong value ($6.27/day was for 11.4MH/s/day), the correct is $0.55/day.

I have collected data from December 2013 

Indeed, it's my mistake: I forget to change the value to 0.55 USD/day.

If you want to buy an ASIC (Scrypt) for 10K USD and earn something, you have to get at least 300MH/s!  

Probably in next week...


The calculation was updated!


It is based on a six-month statistics (for Scrypt algorithm).

I am proud to present my Mining Profitability Calculator (for Scrypt).
Please note this is still Beta version!

Test #1: Innosilicon A2 Terminator ASIC 90MHs Scrypt Miner:

I found A2 Terminator 90Mhs Scrypt Miner $10,000 (plus $200 Shipping)
Link here: https://bitcointalk.org/index.php?topic=596317.new#new

Price: $10,200
Revenue: $2,392 - 10,200 = -$7,808
Max Revenue Days: 175
Return Of Investment (ROI): 23.45%

If you have other ASIC's or Rigs for test please let me know:


1. Hash Rate [MH/s] - Scrypt
2. Initial Revenue per 1MH/s [$]
3. Power Usage [Watts]
4. Electricity Price per 1kWh [$]
5. Equipment Price [$]

A2 Terminator 90Mhs Scrypt Miner $10,000 (plus $200 Shipping)
