What should a gpu miner have in his bag of tricks?

[garetjax]

Sadly this thread just came in really handy.  I only have 2 rigs, have had them a few years and one just died.  It boots, sees my video cards, then miner crashes and the rig also looses network and goes down.   Tried new risers, only using a single card, etc.    I think its the motherboard, and since I don't have a spare I ordered one along with a psu tester that Phil listed.

One question that I thought of this morning... for those of you who have small farms in your home, and have invested hundreds, thousands, (more?) into your hardware...  What are you doing to insure your hardware?  Do you add it on as specific items on your home owner's insurance?  Or do you get a separate policy to protect them?  As I'm considering a large investment over time (by my standards), I got thinking gosh what if I had a massive power surge that fried everything.  Or a rig catches on fire and destroys them all.  Or a basement flood.  Or... Or... Or... 

And to that end, do you guys leave your gear running if you got off on vacation for a week? 

Insurance isn't a tangible tool, but maybe a tool I should have in my bag of tricks? 

[miner29]

Mine are all covered on my business insurance and specifically listed.  But i dont mine at home...i have large industrial buidling.

Ive got smart switches on every rig so i can power up/down at will from anywhere. So for me 24/7/365

Something i havent seen listed...FANS... extra fans for the problems that arise.  Both 100x100 or 120x120 but also spare gpu fans.  iroberts has been a reliable fan source for me...there are plenty. 

And when a gpu fails and you cant get a replacement fan or its too expensive...the zip ties and the 100x100 or 120x120 will do the trick.

[DigitalFarns]

Miner29, thank you.  Those are great points.  I had thoughts that spare fans would be good.  I am interested in your smart switches, would you mind sharing details with us on that?  I would like to be able to remotely control anything I can.  I use remote desktop software at work, so I can work from home if needed, just like I'm sitting there.  I would like to setup that same interface if possible for my rigs.  Probably mostly so I can count pennies every day LOL.  But I like the ability to be able to shut it down if needed, that's cool.  Do GPUs alert you if a fan goes out, or do you need to physically look at them to make sure they are all spinning?

if you use simple mining you can look at your gear from all over the world.


and if you use the switch above with 1 pc and

Speaking of smoke detectors, they are good however they won't help you when you are not home. I think its rare to have someone's house burn down due to mining. I had many melted cables, PSUs blow up, GPUs go Kaboom and emit black smoke and make the place stink afterwards, however none actually started a fire.

What I would do in the future is just keep the rigs on metal frames and keep the frames on a metal rack away from anything flammable. So don't put it next to a wall or near boxes which are easily flammable.

They sell these type of blow up balls which basically you can put near your rig, if it detects any heat, they will blow up and send fire extinguisher powder everywhere and hopefully put out the fire. Never tried this however.

fire blankets can help.  Amazon has them. I have a few here and there.

Let's not forget about:

• USB sticks

        very handy when using linux distros like smos, etc. Should have good read/write figures to easily reflash if needed.

• lombar exercises (daily)

        I almost killed my back carrying rig cases from one place to another . I think this should be in top 3 .

That looks more expensive than the Simple rig resetter from SMOS, It can handle upto 300+ rigs with an extension board and pings your miner every 2-3 seconds to see if its still alive, if not, it powers it off and back on again.
I bought 3 of these SRR devices in '16-'17 and have never looked back.

It is more costly as it monitors power use on each rig.

It is basically a remote pdu with meters for each of its 8 sockets

It allows any rig or asic up to 12 x 240= 2880 watts per plug

grand total of 24 x 240 = 5760 watts

It does more than simple  miner rig resetter does.

The temp rise is the alert.  If you have the miner screen up you can see the fan speed drop or go to zero.  Usually its a gradual rising of temp as fans wear out.  What crazy is some fans didnt last a couple of years...some i have are on their 5th year running 24/7....
I run Ethos and mmpOS on my rigs so they monitor temp snd will shut down card or rig if a problem arises. 

As for power plugs i use these...

https://www.amazon.com/KMC-Monitoring-Compatible-Required-Function/dp/B07313TH7B/ref=sr_1_1?dchild=1&keywords=kmc+plug&qid=1610718643&sr=8-1

The actual unit is marked at 100-240v.  I use pdus then have these on each plug on the pdu.  Also monitors power usage by the plug.  Phone app gives me control from anywhere.  Was the least expensive solution i found.  i have over 40 of them installed.   I only run them on rigs rated 10a so no where near that for a rig.  Need wifi for them to work.

They make a handy plug to go into my pdu C15R to the C14 plug on the switch.  

https://www.amazon.com/gp/product/B01IBIC1XG/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

If you are on 110v power can plug straight to outlet.  For my biggest psus 2600watt...they take dual power plugs and just stick 2 switches one to each plug.  im on 240 so i have to use the little adapter plugs.

They monitor power use which is nice.

here is what the gear I have is running in my house.  Just a 2 board s9 with braiins firmware.

1 of 8 plugs is power on.  And we are running at 117 volts as the gear can do 110 to 204 volts.

Wow this is a bunch of great information guys, thanks!  I'll take some time over the weekend to try and absorb this. 

With planning to build this in the cold storage area of my basement, everything will be basically encased on 5 sides (3 walls, ceiling and floor) of concrete.  Trying to decide what to do for the 4th wall, I'm considering doing a simple framing job, install a metal door, sheetrock the inside of the just the newly added wall for some fire protection, and then covering all the internal surfaces with that automotive material for thermal protection and sound proofing.  Also reading up on some air movement ideas to push cold air in down low and push hot air out up high.  Still waiting on a call back from the power company to learn what my options are for installing some more juice to the house. 

I also found some inexpensive indoor/outdoor thermometers, and i figured I could put three of those in the room - floor, ceiling and in between to keep an eye on room temps as well.  I'm geeking out about this pretty good LOL.

Looking at specs of what appears to be the current model of this switch (EPCR7) https://www.digital-loggers.com/epcr7spec.pdf

It has 4 "pairs" of managed plugs on each of two circuits - an A circuit and a B circuit.  I'm trying to understand the electrical math.  The spec sheet I linked to says it can do 30amps, 3600 Watts.  But I thought that 30amps = 7200 watts? 

Each Rig I plan to build has a target of 440 watts - CPU plus 3 GPUs.  I am hoping that I can eventually run 12 Rigs on one 30amp dedicated circuit for a total draw of 5280 Watts.  But I can't figure out if I can run this on the EPCR7 (6 rigs on A circuit and 6 rigs on B circuit).  Or if I would need two of them to do it.

my model is a bit older and auto selects 120 to 240

so it would do 3600 at 120 derate by 80% 2880 watts  and I would fudge down to 2500 watts  or 4 600 watt builds

and it would do 7200 at 240 derate by 80% 5760 watts and I would fudge down to 5000 watts or 8 600 watt builds

I buy them used on eBay and so far so good.

What do you guys think about something like this to help dampen the noise from several GPU rigs?

https://www.amazon.com/gp/product/B007PBK6A6/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1

These aren't ideal - I'm still looking for something that's 100% natural fibers like wool/cotton because of not wanting synthetic fibers in case of an electrical fire.  These are 70/30...  but I'm still looking...  Do you guys think that lining the walls, ceiling and floor in the mining room would help dampen the sound a little bit? 

My concrete room that I'm going to build my garden in will be sealed off, and hopefully sound into the house won't be nasty, but I'm thinking about when I'm in there servicing anything, the noise bouncing off the concrete surfaces might make me insane.  I mean earplugs are cheaper... but I'm just thinking long term, this might be useful to help dampen the sound...?  I'd be curious to see if any of you guys are doing something like this?

I thought about those welder blankets too... I have smaller ones that I use to protect my fireworks ignition systems for when I do fireworks shows.  Where they have those grommets in them, I was thinking I could run masonry bolts into the concrete walls and hang them like drapes on the concrete, but the concrete doesn't need any fire protection, mostly I'm just trying to baffle the noise.  A lot of the good sound absorbing materials would be awesome, except for the fact that they are synthetic and could melt/burn if a problem arises.  So that's why I was thinking the cotton/wool blankets.  You know how bad noise will echo in an empty room with no carpet, or furnishings.  That's what I'm thinking.  I'll check out the UltraTouch product.  Thanks!
