As an electrician, I can tell you this thread has gotten DANGEROUS. I will come back in a day or so when I have a little time to address your questions and problems. I the meantime, refer to this article I wrote in 2007:
https://www.overclockers.com/how-much-is-too-much/

Basics to address:
Watts is watts, which is to say Volts x Amps. There is a lot of other math and efficiency factors involved, but for simplification, you can have 1200W from 120V @ 10A or from 240V @ 5A. The lower the amperage, that smaller the wire.
Generally speaking, higher voltages can be more efficient, but are more dangerous to people. Higher amperage offers greater risk of fire from poor connections. If we are going to raise your voltages, we want to protect you at a lower amperage - no splicing directly off of dryer or range plugs
I want to get everyone here away from using extension cords, cheap power strips, taps, etc. There are safe ways to do this. No stats rating is worth a house fire, and most house fires are from poorly done electrical work.

exactly why I put my big machines on 240V. I re-purposed a kitchen stove outlet, in a room that would no longer be used as a kitchen, and stove removed. I also had an electrician check it over. swapped the breaker to 30A (lower than it was previously) to match my 30A PDU (which has it's own set of 8-12A breakers on grouped outlets).

re-purposing a dryer outlet is probably fine, IF you are not running the dryer off of it as well, and you do not try to increase the amp rating on the breaker (and best to use a a PDU with it's own smaller breakers as well). running a high watt computer and having the dryer plugged in as well is a big NO.

I am very sensitive to the subject of having heavy duty enough extension cords. I am running 1600 watt PSU's and have no interest in burning down my new when I bought it mobile home.

I did talk the 110 volt stuff over with my brother, an BSEE with significant Electrician experience.

Besides measuring my loads with a Kill-a-watt meter. I have upgraded a GFI breaker to the same amps as the circuit breaker. And get bothered when the plug gets more than slightly warm.

It now seems to me that short of some major 220 re-wiring by a licensed electrical contractor I am not going with the 220 v option.

I have an electrician coming over on Thursday to check the whole house panel. Lights flicker whenever something comes on. GFI pop whenever anything gets plugged in. So it's time to have the whole thing looked over. Wouldn't be surprised if the original owner skimped on the wiring.

While they are not too useful on the special Linux app, there are some "RX-570 mining cards" now being offered in the $50 price range (DIY cooling) on ebay. I ordered a couple for use on Einstein as the RX cards seem to do well on that project. Have not received any yet but the pictures I have seen appear to show a single HDMI output which is a lot more than any NVidia mining cards have.



Got a pair of these in. Unfortunately they do not support OpenCL. I tried bios replacement: two different RX-570 and even an RX-560 bios before restoring the original bios.

When booting 18.04 all cards are "seen" by the OS: eg: the "mining only" card., a regular RX-570, and a regular RX-560, but none of the cards are seen by Boinc nor even "X".
Looking in /var/log at syslog, I see "AMDGPU_INFO_ACCEL_WORKING = 0" followed by "AMDGPU DISABLED" which I am guessing disables even the good cards.

By "seen" I mean that lm-sensors reports a bus id, temp, etc. for all cards including the "mining only"

Windows sees all cards and attempts to load RX-570 drivers but fails. Boinc sees all other cards unlike ubuntu.

LIsting of difference between the "Ethecoin RX-570 (v)1.1" and a Gigabyte gaming RX-570. BTW, Ethecoin is not misspelled. Other id on the card: SNDRX57004

Cannot return the cards. May do a visual surface compare to spot the difference. If I had a defective RX-570 I could try swapping the bios chip. Unfortunately, Gigabyte repaired both of the defective RX=570 boards that I had.

Any ideas? (too light for a boat anchor)

It's just a thought, but (as with some Nvidia drivers) you may have to install the OpenCL component separately though I'm not sure if the same method is good for AMD cards.

This is what is use for Nvidia cards, though it could probably work for anything, but someone with more knowledge than me can either confirm or rule it out.

sudo apt-get install ocl-icd-libopencl1

You must use the AMD proprietary drivers to get a compatible OpenCL component installed.
First get the drivers from AMD.
https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-570

Then install them with this parameter.
./amdgpu-install -y --opencl=legacy

For the docs look here:

Didn't help

The system works fine with an RX570 and rx560 but adding in the mining card causes all 3 cards to be "unseen" by BOINC.

Windows actually gave a better explanation of the problem but I was not quick enough to get a screen print and was unable duplicate the install. Before the popup disappeared it mentioned some OpenCL entry point missing. Windows also had a working RX560 which was not ignored by Boinc.

Tried to get a $50 "mining only" card to work with BOINC. Was able to do it for NVidia P102 and the P106 series but the RX-570 "Ethecoin" was a bust. I got "close" but that counts in horseshoes and grenades only.

Picture of the card


The collection of tools I used to figure out WTF I had bought are here:
https://github.com/JStateson/amd_vbios_tools

Windows shows a yellow bang for the card but it co-existed with other cards.
Linux had a problem: BOINC did not see any working GPU cards when a single non-working was installed.

Using a tool, I downloaded the bios 113-eth-sam and used a hex editor to see that it was made by SAPPHIRE

Went to techpowerup data base and tried flashing every bios listed as SAPPHIRE RX-570 cards. Looks like
the mining card is based on a "Pulse MINI" or ITX.

The only bios that worked was Sapphire.RX570.4096.190114

I thought I had hit the motherload: Windows liked it, GPUz looked great. All values, sensors, etc were within specs. Unfortunately, BOINC did not agree. The card ran idle and nothing was computed.

Picture and "evidence" is here. Look at the "rx_all" picture to compare working RX560 to "flashed" RX570
https://github.com/JStateson/amd_vbios_tools/tree/master/docs
Front of card:  rx_front
back of card:	rx_back
GPUz card data rx_front
GPUz card sensors rx_back
GPUz sensors when Einstein app is running (RX560 works, RX570s do not)
Bios_info: for the SAPPHIRE card with the original 113-eth-sam bios


Going to email SAPPHIRE and beg for help from tech support. Maybe someone here has a better idea or knows an insider at SAPPHIRE.

This is the MSI B360F-Pro MB with the I9-9900k cpu. The URL in the previous message doesn't display the actual MB info. But otherwise, it pretty much lays out what I have on that system.

I consolidated the MB and 1st 8 GPUs onto an EVGA 1600 watt PSU with the new 10 gauge extension cord. The last two GPUs are sitting "loose" as well as the loose 850 watt PSU.

The other thing I demonstrated is I need to buy longer Ugreen USB 3.0 cables as well as that Mining Rack (19 gpu) that Keith proposed in another thread (ease of assembly rules all) and replacement EVGA power cables that goto 8 pins on the dual ends. Without those cables being all able to drive 8 pin and dual 8 pin GPUs I will run out of sockets before I run out of GPUs... I am going to wait for the next paycheck to do that though.

If I had not stumbled over that 10 gauge extension cord locally I am not sure I would have taken down the system and made those changes.

So far this rig has been very stable. If it continues that trend I will feel much more comfortable investing in the additional hardware in 2 weeks.

One major benefit of a mining motherboard is you don't have to wonder if it will boot or fail during the POST when you add another gpu by plugging it into an open slot. When you start using the 1 to 4/8 expansion card on a 6 slot motherboard you are never sure if you will get out of the POST or not after you add another video card.

The B360-F Pro MB is taking a vacation. It quit processing yesterday. And when I looked at the log it was complaining about virtualio missing as well as PCie errors related to the video cards.

I spent a couple of hours tinkering and then said enough for last night. I went and read about English writers instead.

I will do a full reset from the ground up using an external video card either tonight or maybe Thursday night.

The original plan was to always use the iGPU for the video. But given that I am getting video card errors and an odd description of the Drivers in software update I am going to drop that for now.
Unfortunately, now it is cranky and booting with a scrambled video screen that is un-readable. Hence the "full reset".

I hope to be back up to 8 GPUs soon. And then I will start looking to see if I can find the same hardware errors in the Log.

I am very glad that I don't depend on this system for income! :)

Meanwhile, my "other" machine continues it never-ending production :)

That was interesting. I was having a very slow laggy screen up to a few minutes ago. I reset the two places I can set the PCIe speed to "auto" from "gen1" and it boots faster, the snap crackle and pop are back...
