You do realise a Wake on Lan packet can do nothing for a hanged PC? The Only thing you can do is start a pc that is already shut down.
How are you even comparing a Hardware solution that Indipendently monitors and restarts machines when needed automatically without the need for manual intervention to a WoL packet???

Better for us primarily because its a smaller size. Its actually lower performance because of it being RX 470 4GB cards. Also, its more profitable for the guys at Pandaminer since the cards are cheaper.

I think a 4GB 470D mod is more likely, with the 470D cards being cheaper than even 470's.

Use PCIe risers that come with 6 pin connectors instead of molex/sata (they are availible now)
Use 1X2 PCIe power cables for the Server PSU, oir get PCIe power splitters, and use the two plugs per cable in GPU Power and Riser Power, thus powering One Card from one power slot.

Hello Ol Timer. Things haven't changes since you left, the Z77, Z87, Z97, H81 based boards are still the best for mining.
Unfortunately, like you mentioned, they are hard to find. See if you can find an Asrock H81 Pro BTC V2 board, or a Biostar TB85 board.
Good alternatives are the MSI Gaming 5 Z97 which support 7 cards, but are slightly more expensive.
In any case, holler here https://bitcointalk.org/index.php?topic=1806061.420 many good folks from the EU who can help you get boards.

Now, the ASROCK FM2A88X+ BTC - I started mining last year and these were the only boards I could find. You cant use Athlon X4 cpu's with em coz its a socket FM2+, so get the cheapest Am4 APU like the A4020.
I have 8 of these boards, running 5 cards off a 750W Gold PSU each and never a hiccup in the last 10 months of continuous operation, so these are pretty good.

Happy mining.

This is the perfect category to post this request. I would have been super interested, but unfortunately I have 100+ 4GB RX 470's.

What would be a good PSU for a mining rig with Asrock BTC and 6 RX 480 cards?
EVGA 1300W is what the majority uses. I personally use Corsair RM1000X and it works flawlessly. I have my cards undervolted so they consume under 120W per card.
Should I use USB powered risers or ribbon powered risers? Powered risers or unpowered risers?
Powered Risers, since the current generation of AMD cards draw a lot of power from the PCIe slot itself. Older cards did not, and so unpowered risers worked fine on them.
Should I have one PSU for one rig or 2 PSUs for one such rig?
One PSU is usually less hassle and easier to setup and what I personally prefer, but 2 PSU's give you easier resale since its hard to sell a 1000W+ PSU. You will need to get a PSU link type cable to get two PSU's to run in tandem.
What does 80+ PSU means?
80+ is a ratings standard, it means that the PSU will at all times deliver atleast 80% power efficiency, which translates to little power loss. Most Gold rated PSU's actually deliver 93+ efficiency.
One RX 480 cards will use 150 watt each. Mobo 100 watt. So total should be 1000 watt.
Some suggest 1700 watt PSU.
Again, 1300W is easily sufficient for 6 RX480's, and even that i feel is overkill. I run them with 1000W PSU's but you need to undervolt to keep power down.
If I have a 1700 watt PSU and I only use 1300 watt, will the PSU actually use 1700 watt nevertheless?
Ofcource not. The total power consumed from the wall would be (Cards+Motherboard+CPU+SSD)/(PSU Efficiency) so for  a 6 RX 480 setup at stock, this would be (900W + 30W + 40W + 10W)/(0.93) =  1054W.
Realistically with BIOS mods and undervolting, you should draw no more than 120W per card, so total power would actually be (720W + 30W+40W+10W)/(0.93) = 860W.

OOOoooooo if you can get undervolting/clocking to work like it does in windows with Watttool, I would LOVE your Linux OS Implimentation and it would make Windows obsolete. The Only reason I am on windows is because of watttool undervolting/clocking.


My vote is for Blurred numbers. 0 numbers can represent a rig online but hashing at 0 due to some error. Blurred should represent the rig offline.

Respect.

You are pushing your GPU memory too far, im really surprised they are even running at 2200 when the stock is 1650. Flash optimised timings and lower clocks, 26 is easily achievable with memory at 1850.

Praise be upon you.

More like a custom pcb that has full length PCIe slots to fit regular cards on it. and not just 10, upto 16 if his plans go well.
So its basically like the custom board that pandaminer has, only for regular desktop grade graphics cards. I'd say that's direct competition, but it will most definitely be more expensive.
PS: I haven't seen it but this is my impression of what he is building is, judging by what conversations I have had/read.

That is sooooo accurate bro 😂😂😂

Before whatever that jstenfanop is building makes them irrelevant

All you need is a powerdrill, and you can attach rails to anything.

Only a board like the Biostar GT7 which has 4 physical slots could work in a case like this. And this case has 7 PCIe slots so a maximum of 3 cards. You need something with 8+ slots. And dont worry about stackable.

Can I urge people to remove the 5-6 full page images in every single quoted reply? Its getting pretty tiring to scroll through page after page with quoted images that aren't even needed.

What do you mean 8+ "switches"? Can you share links to posts/pages that elaborate?

Changed the wording above to make it clearer. What I meant was, the lowest stable clocks that you found for memory should be applied to the core as well, and to from there to undervolt the core you will need to introduce an offset as directly changing mvs below that wont work.
Also, Polaris is an efficient architecture so it uses much lower core values than Hawaai/Tahiti so stock clocks are stable at 1000mv on almost every chip, while memory if pushed to 1900+ will need the full 1000mv that it defaults to, so in most cases the higher mvs are on the memory not the core. Unfortunately the higher mvs that you key in for memory are also used by the core (ignoring what you specified it to run at) unless you introduce an offset.

Try to Run your cards at factory settings, that means flashing back stock BIOS, and reverting to stock clocks. If the cards are stable, theres your problem. its usually high overclocks or tooo tight timings in the BIOS mod.
If that doesent work, replace the card, then replace the riser. If neither of those work, switch around the risers on the PCIe slots to see if a particular PCIe slot is causing the failure, which could mean a faulty PCIe slot on the motherboard.
Also, change your attitude, if you whine about the community being unhelpful, its a self fulfilling prophecy. Your EXACT problem has been encountered and reported by no less than a 100 people here, and NOTHING that I or anyone else will share now has not been said before ... if only every new poster could bother to spend the time needed to look for solutions already posted.


Seems like you already have found stable voltages for Core and Memory. I am assuming this was at stock clocks? I am also assuming you ahve modded your bios memory timings already. I recommend having core and memory both set at the lowest volts that you can get your memory to work on (because they will each use the higher of the two anyways).
Then you reduced core and increased memory, are those stable at the voltages you figured out earlier? Did the power draw now go up or down?
The next step would be to introduce a voltage offset for the core in a tool like watttool Because you increased Memory clocks you can not reduce the volts to it, infact you may need to increase them if higher memory clocks arent stable. Then because you lowered core, do not change the core volts but put in an offset, lets say -50mv (directly changing core volts to below memory volts will make no difference) and see if that is stable. Repeat with a lower value till you hit the lowest stable setting.
Remember, with every change in clocks the volts needed for it to be stable would also change so its a hit and try to find the perfect balance.
