Mitchell - the symptoms you are describing are very typical of a PSU that is way below what you need. Try running one GPU for a bit, make sure each GPU is working correctly in each slot. If you are trying to use extenders, check them all, in each slot with each GPU - this will take time, but you do need to know that all the "external" stuff is OK when running on its own before you stack four in on extenders. Next try with two GPUs, again testing all the combinations of GPU, slot and extender. Repeat again with three GPUs, and finally putting all four in. This will take time, so don't try to do it in a rush.

Over the years I've found the Coolmaster calculator to conservative by between 25% and 50%, so use with care!
The Outervision one doesn't understand recent equipment, so its not as useful today as it once was.

Got a call from PC shop tonight. Looks like CPU cooler is pooched. CPU was overheating 95C. Having them put in a stock fan cooler $30. If it runs ok, then RMA the Corsair H80iGT. Interesting no alarm went off. After I re-flashed the BIOS, I did see no alarm was set. I don't know if it was always that way or a result of the re-flash.

Rats! I thought you were talking about dying Linux Users (terminal)......

I am still concerned that you are starting in the wrong direction. Do a power budget - how many watts is needed to run a cluster nodes of a given size (choose a cluster size that is scaleable, say ten nodes), including your support hardware like Ethernet switches & routers, power control hardware, dc/dc converters, this will give you an idea of the size of solar panel you need, and the size of you battery bank. You can then work out how many of those sub-clusters you can get for your $10k. This sort of budget can be done without buying a single bit of hardware, just studying the data sheets for the various components.
As for the structure - how it is built and the materials used are going to be driven by the size of the major "solid" lumps - the cluster, the power supplies and the batteries are probably going to be the biggest items that need to be protected, the panels should live outside mounted on simple frames secured to the ground.


[edit]
I'm not commenting about your use of crowd funding in the form of a "GoFundMe" appeal for this venture, as I do think the concept is a worthy one, just that you need to put some more flesh on the bones before setting out on the journey.

Wow! I'm impressed, at least one of your cats is wearing a collar, Grace won't wear one, She has pulled them off in the past.

I would echo Rob's concerns, and I would also add that GoFundMe's are supposed to help out people short term that are down on their luck, and have an unplanned family or personal crisis. They are not meant to pay for ones hobby.

So, as far as I can tell the campaign is well within the boundaries of a GoFundMe compaign for a project of this type.

For your other concerns and additional information: First, I have to say that I didn't include a lot of those specifics specifics because I didn't know how many units I would end up with. I would then determine what of those requirements I would need to cover the minimal number of units and could start adding them in as Campaign Updates to keep interest in the campaign going.

But you all know that things like Number of nodes, routers, switches, power budgets etc would all depend on the amount of funding I got, number of nodes I could get, type and quantity of solar panels, batteries to hold the power from the panels et cetera. Then I would have to determine the materials for chassis, weather proofing ( do I want to use plexiglass or weather treated plywood, or PVC or a combination of those etc). But as I said I was planning on those as project updates, as those figures would change as new funding arrived or I was able to get them myself, units were added on, et cetera.

I was able to get one ODROID-XU4 myself and am working on another, so I should have enough to start the cluster process soon and then see how it goes as I add more units. I have a small 6v 12v 10a solar charge converter now and a small panel and battery, so I was going to use that as the test bed and then go from there, but it just didn't seem logical to create a small campaign and then another larger one as you would loose the momentum of past donations which can encourage new people to pitch in.

In regards to my experience and pas tissues with a GPU rig I was setting up had hardware compatibility issues which were resolved and is up and running just fine. But first off, this is all a learning experience for me and I clearly state that in the details of the project. I have setup and manage clusters at work for VMWARE and NetApp appliances and the like. The clustering of Raspberry Pi's I have done small ones to learn the processes of it all. But I have never done one with the ODROID's and yes it will be a learning experience but I believe most things are and I have people here on the forums to ask and of course Google. The hard part will be getting the initial cluster up and running, but usually in my experience adding additional nodes is pretty straight forward. Power monitoring and regulation will be a challenge, but I was looking into using and Arduino as a monitoring unit that can run on it's own rechargeable battery pack and do unattended shutdowns and startups if power runs out in the batteries at night due to insufficient charging during extended cloudy days or storms or snow et cetera.

Oh and the initial cost of the project being $10,000 as the goal. When I originally created the campaign, the amount GoFundMe put in there was $16,000. I reduced it to $10,00 because if it did get interest and funding, I wanted a high enough number that I know would allow for enough funding for all the materials that would be needed for a decent sized cluster and for any unforeseen costs that might happen. Like I mentioned before, there is a lot of different things involved in a project like this, not just the computing, but the solar power items, including panels, mounting materials for panels, batteries, solar charge controllers and regulators; but wiring, elemental protection, Arduino's, humidity, moisture, air quality sensors and on and on.

So I hope that helps clear up some of those concerns, questions? I don't reckon I know everything I will encounter, but I am sure I can overcome it alone or with help.
