Fantastic thread, Yipyip.  It was really helpful for me.  Even though I'm not technically a newbie, there is a lot to learn in mining coins.  I've tried the Add2PSU device and found that I couldn't get it to work.  2nd PSU would blip on really fast and then shut right off.  At one point, as I was fiddling with everything, I hit the power switch and saw a small puff of smoke come up from the motherboard right in front of my face from a tiny (literally .5mm^2) chip on the MB.  I thought "crap I've fried my $200 MB" but restored the cabling to it's original config (removing the 2nd PSU from the system) and it booted up just like normal - whew!

Based on your advice, I'm going to invest some coins to get a new 1500W PSU (my main one is a 1000W, good for running 3 video cards and that's about it).

I also thought it impressive you managed to cool your rigs when temps outside were 100+ deg F without air conditioning.  Very impressive :-)

Cheers, mate.

Hi Yipyip,

I had ordered two Inline fan from amazon this one:

http://www.amazon.com/gp/product/B002JQ14F8/ref=oh_details_o01_s01_i00?ie=UTF8&psc=1

I will try to play with it, one as exhausts and another as intake.

Let me know if you try the motherboard Supermicro, it looks really good,

Thanks

They are pretty small i.e 100mm diameter ... try and get 300mm and then run 2 splitters on it to get 4x 100mm pipes

Depends on how many rigs u have ... also as in my case I just treated the room as one bi box etc as per this

Hi YipYip,

I have a question about your intake/Exhaust system.

I live in Venezuela, and the temps outside are 95F.

For 12 rigs with 4 x 7970 each one, I use 60.000 BTU of air conditioner (without exhaust.) only with fans.

I read that you use 2 intake with ducts, and 2 exhaust to run 8 mining rigs with external temp over 100F.

Can you show me some pictures of your setup.

Im thinking of opening a new datacenter and want to reduce the air conditioner.

Thanks for your help


We have now moved into winter on our side of the world ..(thank u jesus or satan or whoever..lol )

It has enabled me to remove the ducting directly onto the cards etc

I can show u the stuff that i have been using and also the fans them selfs...but that aspect i have now taken down as it is not needed

I currently just have 2 massive air exhausts at the ceiling and 2 largish air intakes and the floor ...creating a top-to-bottom current type of deal...etc

Having said that once i get my iphone back from being repaired i will take some snaps of how i had it setup ... long story short air intake 4  x 100mm ducts split from a 350mm air intake going to 4 rigs ...so I had 2 x 350 mm air intakes for a total of 8 rigs/100mm ducts  in this tiny room

With the high heat u need to be directing the cool air onto the cards and the next step if u still have heat problems would be to have a air exhaust duct taking the heat back out like a vacuum cleaner etc Cheesy

Getting this to work is a LOT of fiddling around  until u get the positioning just right ...but it is all very doable Cheesy

Hi all.

Just received my USB PC Watchdog card from Berkshire Products, great little tool and worth every cent.

I found that because my rig is under such load and very laggy the "heart beat " program running on the rig would not respond within the correct time frame, multiple tests confirmed this over a 12 hour period.

The solution was very simple, the program can turn a . exe program into the "Heart Beat" (.exe to monitor) , one is able set cgminer.exe as the "Heart Beat" and because cgminer.exe is blazing away (always on) it keeps the USB PC Watchdog card timer from resetting the rig, as soon as cgminer.exe hangs/crashes or locks up in anyway the Card then Resets the Rig.

Will be implementing these across all my rigs.

Just my two bitcents worth.

Really cool cards KISS .. Cheesy

Will implement mine along the same lines as yourself.. nice touch

I am hacking away with raspberry PI and relay switch's but this has turned into a complete love afair with teh PI itself and not actually solving the problem...lol

I have ordered another 20 units from these guys as the commercial solution to this problem Cheesy

Great solution for ~$65 a unit

Some motherboards have integrated watchdog functionality. These are usually server/workstation grade boards. I have not done the math if this makes sense financially; just thinking out loud.

Also these boards often have built-in KVM-over-LAN IPMI functionality for out-of-band management.


Links Please of units with all said functions and place to buy....

There is definately a price point cut off for this funtions but considering that my current default mobo Z77a GD65 is ~ $200 in Australia an extra 100 or so would still be worthwhile Cheesy


Here is one with six PCI-Express slots, Watch Dog, and IPMI 2.0 KVM:
http://www.supermicro.com/products/motherboard/Xeon3000/3400/X8SIA.cfm?IPMI=Y

Financially, you really have to calculate if it is worth it though. Sometimes you can get piles of used servers for really cheap, when a company goes out of businesses or upgrades.

Places to buy: https://www.google.com/#q=X8SIA-F&source=lnms&tbm=shop&sa=X&ei=R36eUfC8DcXRigLhhoGQDQ&ved=0CAkQ_AUoAw&bav=on.2,or.r_qf.&bvm=bv.47008514,d.cGE&fp=139f6c2fdb58a26c&biw=1920&bih=1084



Thats not such a bad board ...5 usable slots and at $248 on amazon...I will give it a go on next MOBO purchase in 2 weeks and give feedback Wink

Hi yipyip,

About this:

http://www.pwrusb.com/powerUSB-watchdog.html

I like the Ubiquiti mFI because it's wireless, and don't need a USB port to monitor it.

I remembered my English teacher from high school...

whenever she came in... me and my classmates will start counting how many "ANYWAY" she says...

anyway.. on this thread.. you gotta count how many "LONG STORY SHORT"..

Cheesy

good thread.. and good info... long story short.. +1 on this thread...

Question for you, YipYip.

How do you find those Berkshire Products - USB PC Watchdog Timer Cards?

Looking over the product details, I want to put one in each of my rigs, will save so much downtime.

What is your feed back on them? Do they work as designed?


Cheers!


Click on the link and order them direct...i just got 2 sample units and they work a treat as designed

They run off USB and connect directly to the reset +/- pins on the mobo

U run a client heartbeat app on the rig and if and when it locks\freezes\BSOD it will wait a preset time i.e 1-5  mins and hard reset the RIG as if u pressed the reset switch ....also will wait a preset time to allow the rig to boot and run up ...just put the heartbeat app shortcut in startup and u are done Cheesy

There is full API if u want to get under the hood vb.net and c code libs as well which is nice Cheesy

$83  1 off and $72 10+ buy price is pretty cool ... real plug and play type of stuff ... they are in coke machines and all other remote kiosk type devices that have a brain.. Cheesy

Thx for that, I had looked over all the info and understood how it all works, it's a nice clean simple solution for each rig.

Thanks for the feedback and info, Will be ordering a couple of samples before I grab 43 more.

Cheers!

Also found these guys similar to the Ubiquiti unit

http://www.pwrusb.com/powerUSB-watchdog.html

Are around $89 a pop...have UK at this point only and waiting on a reply as to either US or Australian solutions etc

Hi,

I don't know about USB Watchdog, until today.

I use in my setup a solution from Ubiquiti, called mFI.

The power strips connect to my wireless network, to the controller, where I apply rules (turn on or off the power) if any conditions or all conditions are meet. Like If current on power strip one is below 6A, turn off, and wait 10 seconds, and turn it on again.

In my lab, I tested a lot of rigs, and the amount of power can tell to me if the rig is mining OK, or not.

Thanks for your information,


They look pretty cool .. whats the cost on those units ??

The mFI mPower strip with 3 outlets cost 59$ (max load 15a, one machine). They have in production a mPower with only one outlet (Will cost 39$) that will fit better in my setup, but they don't have ETA for that product.

Jama gave me some great info on using a Rasberry PI to control all of this setup

Here is the detail

I just grabbed a one of these bad boys
http://www.auseparts.com.au/index.php?route=product/product&product_id=118

Also the relay board u had was using arduino so i thought i needed one of these interface I/O boards
http://www.ebay.com.au/itm/330838954789?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

And of course i grabbed
http://www.ebay.com.au/itm/390568255094?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

You dont need to get the $120 version of the PI or the Seperate ARDUINO I/O board but i did because I am a nerd ...lol

Here are some links and advice

That looks like a good Haul of stuff.

The IO board is not necessary but it is better to have it (I don't)
As the Pi's pins are only 3.3v logic where that relay board uses 5.0v so that way is better for the pi
You are on your own getting that working i'm afraid.

What I can help you with is:
Getting your pi accessible through the internet.
Read these 2 tutorials to get a dynamic address that auto updates.

http://www.stuffaboutcode.com/2012/06/raspberry-pi-access-from-internet-using.html

http://www.stuffaboutcode.com/2012/06/raspberry-pi-run-program-at-start-up.html

As for getting webiopi up and running this was what I used

http://www.youtube.com/watch?v=wGahWkjettw

I will draw you a diagram on how to connect the relays and get that over to you tomorrow.

A warning in advance, you will be splicing the mains wire 110 or 240v so know what you are doing and take appropriate precautions. Also it does not comply with any safety regs.

And also

I have had a quick look into that board and it appears you can use it just as an IO buffer, which is what you want.
Meaning that if you connect it all up. when you toggle port 1 for example on the pi, one port should go high on the board.

I have drawn a very rough diagram for 4 channels.
The numbers I have used are just for example, and I have also assumed you are US or somewhere non-uk so have used (hot, neutral and ground).

I have just drawn one power cable as the others are just repeats.

If you want me to clarify or draw a different way I will.

Here is the diagram: http://imgur.com/sZTAzNK

You can have all of this setup to remote control 16 rigs for about $45 on the cheap ...now u cant beat that Cheesy

Thanks JAMA
