Anyone managing to change vcore on the  fly  with MSI Afterburner?     

When idling it does change the vdcc, but when the gpu is in full load, the changes are not being applied.

Hynix memory. I've not started with undervolting yet, but I agree that Performance/Watt probably can be optimized a bit. First step is to ensure that everything runs stable, and it looks promising so far.

Nice results. I have two of these cards and will start mining these weekend. What is your memory? How about power consumption. Any undervolt?

I have a MSI Radeon RX 570 Gaming X 4GB card that was doing about 23 MH/s on Ethereum mining, and no matter how I adjusted GPU and memory clocks, I couldn't get higher than that.

I just tried out the Bios modification concept, copying the strap for 2:1500 to 2:1625, 2:1750, 2:2000 and after these changes, the Ethereum mining operates at 30MH/s.

Before Bios mod: 1150 / 2100 -> 23 MH/s
After Bios mod:  1150 / 2100 -> 30 MH/s
After Bios mod, lower clock:  1100 / 2100 -> 29.5 MH/s

I can run Claymore's Dual Ethereum miner with low intensity on secondary algorithm (-dcri 10), and get about 300MH/s on SIA without any impact on Ethereum mining performance.

A few GPU tests Sapphire 5xx. A few successes, but one problem.

I use:

Asus Z270F Strix - Without any problems, 7 GPUs work or MSI Z270-A Pro 6 GPU ready, I have tried, I currently operate about 10 Rigs without problem (RX 4xx)

Sapphire 570 4GB Nitro+ Hynix - strap 1750 - 1100/2050/-96mv-gpu/+20powertarget = 29,3MHs @ cca 156 on the wall

Sapphire 570 8GB Nitro+ Hynix - Strap 1750 - 1100/2100/-96mvgpu/+30powertarget = 29,6MHs

Sapphire 570 4GB Pulse Elpida - strap 1750 - 1100/1910/-96mv-gpu/+30powertarget = 24MHs @ cca 150-160 on the wall

Sapphire 580 8 GB Pulse Hynix - strap 1750 - 1100/2150/-96mv-gpu/+30powetarget = 27,3MHs @ Here I do not know exactly, a little more than 570, No more than 170

Sapphire 570 4GB Mini Elpida - strap 1750 - 1110/2040/-96mvgpu/30+target = 26,3-26,4 @ 164w on the wall = 169 USD newegg very nice

Sapphire 580 8GB Nitro+ - Hynix - Strap 1750 - 1100/2200/-96mvGPU/50powertarget = 27,8MHs


Hynix on 570 is better then Hynix on 580. Hynix on 570 timing 7777 @ 1750 but 580 hynix 999 @ 1750 but i have to check this because the problem is two different time sets 1: 1750 and 2: 1750 each for another set of memories.


This is my tests, But I have a little problem. The signature for the modified bios driver is ok. But it does not work at the same time 570 with 580 on one motherboard.

If the 4x 570 works and re-sign the driver, the 580 runs but does not run 570.

Simply, it works either it or it. It does not work together.

Does anyone have any advice or idea?

Maybe a new Atipatcher?

Hi Folks,

i'm still a newbie in mining and i read a lot in this forum. First of all thanks a lot for such an amount of knowledge that can be consumed here.
I already have a 100 Th/s contract on mining BTC at genesis mining but now i want to do it on my own.
The RX 480's seem be one of the best GPU's but it also seems to be out of stock all over the world - especially in germany there is no chance to get one.
So i decided to buy 12 MSI RX 580 8GB Armor OC to built 2 Rigs for ETH-mining and Dual mining.

I'm very excited to enter into a new era of this business.

My setup will be (parts are ordered and will arrive in about 2-3 weeks)

12x Radeon RX 580 ARMOR 8G OC
2x ASRock H81 PRO BTC R2.0
2x Intel Celeron G1840 2,8 GHz (Haswell) Sockel 1150
12x YIKESHU PCIe PCI-E 16x 8x 4x 1x Powered Riser Adapter Card w/ 60cm USB 3.0 Extension (https://www.amazon.de/gp/product/B072BJ3GCG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1)
2x PSU Corsair AX1200 i Platinum
2x Corsair Vengeance LP Series Black DDR3-1600, 4GB
2x Patriot Spark 2,5 Zoll SSD, SATA 6G - 128 GB
2x Desktop Power Switch https://www.amazon.de/gp/product/B00LVREYWG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Thanks to this forum I think i'm prepared very well to get the cards modded to enter into a hashrate of about 29 or 30 mH/s. Thanx to Cryptoyeti http://cryptoyeti.com/msi-rx580-armor-8g-review-and-bios-mod-guide/ for his brief explanation getting 30+ mH/s out of his cards.

But there is one question left concerning the PSU. Does anybody have the Corsair AX1200i Platinum and are there enough cables included to connect all components?
Thanks for your comments.

Happy mining, Bodyworks
