Try GPU 2 in a different slot and see if it changes for the better.  If you are using risers I would try a different one of those two.

Im at .048 per Kw\h here in west central Indiana and im still making money.  Waiting out the newbs to sell off all their cards during the great spring/summer 2018 panic.

And the flood of used GPU's is here.  Ill wait awhile...I could use some $100 RX 580s and some 1080s for $200.  Its coming.  Im mining coins now and I got off NiceCrash and they can shove it.  Mining in pools proves alone that NiceCrash was reporting slower output than my rigs were actually making.   NiceCrash showed my blower 1080 producing 370sol/s but EWBF showed 450 consistently.  Ill be in the pools from here on out getting the coins. If I want to give my money away ill give it to someone I like and I dont Like NiceCrash.

Im lazy and I went with the Veddha v3c.  one unit will hold 6 gpu's, motherboard and 2 power supplies.  Two stacked will do 13-15 gpu's if you add a second mounting rail.  Thats what im running.  2 rigs with 2 v3c's  stacked and a Asus B250 mining expert motherboard.

I hate to be the bearer of bad news nuclear sources arent the only ones that produce radiation. The sun, car radio, microwave oven, tv/monitor, xbox one, ps4 and even your GPU all produce radiation.  Not the same types as each other but it is radiation.

Absolutely FUD....Hes got more radiation upside his brain coming from his cel phone than that GPU is putting out.  Id be more concerned over the dust and noise waking me up numerous times in the middle of the night.  The dog's farts are more dangerous than radiation from a GPU.

"hi i installed this fan to all my broken gpu fans hehe works pretty well more silent and and less heatness".....


Less heatness? Is that a technical term? 

My 2 rigs (running nicehash) have gone full retard starting yesterday.  Numerous crashes.  Rig 1 popping up with Nvidia Driver update warning.  I have the latest and it still pops up with it now and then since yesterday (i see this warning because of the numerous crashes and needed reboots).  Rig 2 running without driver warning even though it has the same Nvidia driver updates AND has all GPU's (11) that are Nvidia GTX 10 series. It has crashed less than Rig 1 though.  As if the lower payouts arent enough now ive gotta deal with instability and loss of profit from all the crashes.  Changes are coming soon....at my house.

Its 240vac in the U.S. and has been for many decades.  Find a "great deal" on NOS 220vac plugs/outlets and they will burn up eventually.

This diagram is grossly incorrect.  "system ground" (which is totally the wrong title, its called earth ground) is NOT the same as neutral.  You should NEVER have current flowing through ground (unless there is a ground fault in the load which is what it is for) so you sure the hell wouldnt attach a ground wire directly to a 240v 3 pole outlet.  You do on a 4 pole outlet, thats what the 4th terminal for.  The picture shows the G terminal incorrectly marked. It should be a W.  A L6-30 Outlet doesnt even have a ground wire attached.  Ground is accomplished back at the main disconnect device where the neutral and ground are jumpered.  You dont get the 4th terminal until you get into the 50amp outlets typically in modern souckets/plugs. (NEC rules).  If you have a 3 terminal 50 amps plug/socket, it is obsolete even though it may be new in the box.  Electrical safety rules are there to protect all of us and by default the equipment we attach.

In that case who gives a shit what all romex looks like as long as its safely installed and out of the way.  Theres a fine line between making something too pretty and wasting alot of time doing it and constructing something to serve a purpose.  Pretty doesnt make you money. 

I would look at the FLA (Full Load Amps) rating on the nameplate of the attic fans before I stuck them both on the same 20a breaker.   When an electric motor first starts up and until it gets to rated speed it will draw 5-10 times its FLA.  This will be a problem if both fans start at the same time which will most likely happen if your fans are on a thermostat and also when you first start them up together.  So I really need to know what kind of current these fans are drawing to give you a better idea in your situation.  Why not keep them on separate breakers?  Are you running out of spaces in your circuit breaker panel? There are breakers that take up half a space (2 in 1) that will allow you to only use one breaker space but get 2 breakers out of it.  You also have the option of adding a subpanel to get more spaces if needed too.

The broken divider if thats what you are referring to and thats what im actually seeing in the pic isnt going to keep the card/connector from working.  However what caused that divider to be broken could be a 8 pin plug was installed backwards and forced.

OP  I need a better aerial view looking down into that connector that is in focus.  That pic appears to show the connector has what is called a pushed pin(s).  If a plug is inserted wrong or even just forced too quickly it can break the lock that holds the pin within the cavity of the its socket and if that happened then the solder joint to the board is broken.  Remove the fan shroud and inspect the board side opposite of the 8 pin socket.

Solar is NOT an investment.  Solar is a 75K sports car that is worth 55K as soon as you drive it off the lot.  The sports car will never make you any money before you die.  The car MIGHT be worth more long after when you are dead.  The car will continue to cost you money every year you own it in maintenance and repair parts.  Thats solar.  The battery bank will need replaced every 5-10yrs depending on what type and whether they are abused.  The regulators and inverters dont last forever.  One good hail storm and your capacity is reduced or wiped out.  Whos going to pay for those replacement panels? Genius idea...File a claim on homeowners insurance and get your insurance jacked up instantly...if they even cover it.   All this applies mainly to the united states.  The government doesnt want you to have solar because the power companies dont want you to either and they lobby the government to help with that.  Solar isnt near as green as you think it is.  Its a novelty at best.

Why would you need to "discharge the capacitors"?  Which ones?  Do you have any idea how many caps are on a GPU?  Do you even know what they do?

With Dim LED's Symptom there are only 3 possibilities here.  One is that you simply arent getting enough power to the 8 pin socket on the GPU.  Is this GPU the only one being powered by the power supply?  If it isnt then disconnect one that is working and connect ITS 8 pin cable to the pain in the ass GPU that isnt working.  Does it work now?  If it does then you either dont have a large enough power supply OR your original cable feeding the pain in the ass GPU is no good which leads us to possibility 2.  Did you mix cables from another brand or even generation of power supply?  Ring the ends out with a ohmeter and compare to a working cable to verify.  Then possibility three is that you have a short or open in the pain in the ass GPU.  Shorts definitely cause dim LED's.  Ohm out with a ohmeter from hot side of 8 pin socket to ground side and what resistance do you see?  A open on one or more of the hot or negative side connection to the pin socket will mimick a short also as far as the dim LED symptom and simply not working.  You may have to remove fan shroud to get a better look.  Look for dark or burnt spots on the circuit board of the card around the 8 pin socket. Poor solder connections can cause failure of the joint connections on the board.  Sometimes this type of failure will even burn the traces coming from the 8 pin socket which route power to throughout the rest of the circuit board of the GPU.  4 of those pins are 12v+ and the other 4 are 12v-.   If there is any kind of board failure it will usually show its ugly head and be obvious when you pop the fan shroud off and inspect the board.  Burnt traces, bad solder joints can be repaired.  SMD (surface mount devices) can be replaced but can be a total pain in the ass without the proper equipment.

mine is .048 and im in Indiana

I have two Mining Expert rigs and I have yet to see any settings for Compute Mode in the GPU software (windows 10 pro update 1709). And I even followed the many online instructions (clicking on global).  Anyone know why?

It aint happening this year. Watch what happens in Sept 2018.

I have 2 rigs with a total of 20 gpu's, two of them being 1080s and those cards are making more than a buck a day and always have.
