I thought it was 16.04...  Yikes...you are correct (well why wouldnt you be)....just checked 14.04

Either way it only works with older cards.  i run 5xx/10xx cards on my ethos rigs.  More modern cards are in mmpOS rigs as well as vegas cause i get 50+mhs on my vegas with mmpOS.  

Ill run ethos until the cards wont mine....those rigs are well roi’d.  

There was prelim support to 20xx but never worked well.  

Ethos has been as solid as one could ever hope.  And still running the most recent miners thanks to the miner-manager script.  

For the 60 licenses i own..i got my moneys worth no doubt.  

The buisness model didnt afford income over time...but did sell really well.  Probably the best eth mining system of the day.  The subscription model keep revenue rolling in so updates occur.  

I do not agree.  And here is why. 

Using risers removes all stress from the mobo.  13 gpus on risers are less stress on the mobo than a single gpu plugged directly in to the mobo. 

Plus it helps spread out the gpus so they run cooler. 

Less mobo / cpu / ram / psu / storage device = less cost and less wasted power.  Means more can go into gpus then being wasted on the support hardware.

There is no issue getting multiple psu to work together just some simple rules:

Best to use a Y or W 24pin adapter to sync 2 or 3 psus.  If using server psu then use the 4 pin link connection to main psu.
Always power mobo with the primary psu...connect no other psu to mobo unless it is via a Y or W 24pin cable.
Always power gpu & riser pair from the same PSU.
Do not overload wattage on any psu chain or connector.  Also known as do not use sata to power your riser or gpu.

And most important if building a rig use linux or a linux mining os...you can run from a thumbdrive and can run on pretty slow cpu...like celerons and pentiums and only need 4gb ram max.  Again use the least to get the most. 

Of course this is just my opinion from running my little farm.

YMMV

First pic down the page shows it.

It is screen printed right on the PCB.  Usually white print.

You do...calling some one a bragger is not a compliment.

General setup for AMD bios for mining

    set IOMMU to ENABLE.
    set VIRTUALIZATION (C1E) to DISABLE.
    set POWER CONTROL (SVM) to DISABLE.
    set CPU UNLOCK to ENABLE (this may prevent CPU temp from being read properly).
    set COOL AND QUIET to DISABLE.
    set CPU CORE CONTROL equal to the amount of CORES PER PROCESSOR for your particular CPU make/model.
    set ONBOARD AUDIO/SOUND (AZALIA) to DISABLE.
    set IEEE1394 to DISABLE.
    set CPU FREQUENCY SCALING to DISABLE.
    set CPU PERFORMANCE MODE to ENABLE.
    set FAST BOOT to DISABLE.

Haters gonna hate.

And thanks for sharing.
Please update on progress as you go along.

+1 merit to you

Stale < 1% Invalid 0%  Is the way i prefer my mining.

The good news is you can almost always flash it again and fix it with the right bios.

Yup...usually with dells if you look at the mobo between the slots it will have printed what watt limit is for that slot. 

I prefer to keep my ROI bets to 100 days. YMMV

1) i wont repost scam links (consider removing it from your post/quote).
2) The manufacturers website states that they are not yet for sale...and anybody offering one is scamming.
3) Report the first post to mods here as scam
4) Profit! 

Are you plugging all 4 directly in the mobo...if you are try using risers for some / all of the gpus.  When plugging directly into the pcie bus...it requires the mobo provide power through the pcie slots.  Riser remove this power draw from the pcie bus. 

You need to power the riser.

GPUs can draw up to 75w from the spcie slot.  The riser removes this load from the mobo and provides it by the riser but you gotta plug power to the riser.

I wonder if you are using a ribbon cable full slot extender instead of a usb cable type riser.  If using a full slot extender then the gpu will try to pull power from mobo...which it may not be able to provide.  Dell is not known for over building its systems.

Go to amd panel and turn on compute mode.

it was early but i was like no way its beating eth....and its not....but it may be rising in ghe world..

But the person that made that video is either an idjit or he is purposefully misleading peeps.

I suspect a rookie mistake....but clearly not anywhere near what he claims in profit. 

Some people livin the dream!

What?  Save the bios first.  So what it doesnt have a switch...and even if you didnt save it techpowerup has pretty much every stock bios in exitense available for dl. 

If it bricks they are recoverable...plenty of how to out there.

You fear the unknown but this is not unknown...just unknown to you...get to googling.

As Philipma1957 noted...that will work. 👍

That is awesome.  What you going to be growing?
Looks beefy!

👍

Espeically win 10 home.  The pro version allows group policy home does not.

I switched to linux years ago and have never worried about silly windows again.
I literally have a mining OS that hasnt been updated by maker since 2018...still runs strong today....with all the current miners. 

Windows cant hold a candle to linux uptime.  And windows wastes huge amount of resouces.

My rigs are mobo/4gb ram/ any cpu / 16gb thumbdrive / psu / gpus /risers....nothing else.  Even on the smallest or oldest celeron or pentium runs fine.


Enjoy your bloated windows spyware...becuase no matter what you do...it is spying and reporting to redmond everything you run/do.
