If I do that, then the 1X slot next the 16X slot will be blocked by the GPU.

Problem Solved. So, finally I got all my 5 cards up and running fine. Just got the new Mobo from Asus. So, here's what I did

Once the mobo is connected to PSU, I installed W10 on a new SSD 64GB. Then tweaked some settings in the BIOS. Its not much, just enabled 4G and PCIe config to Gen 2. Then, I connected 4 GPU using powered risers. Suddenly 3 Cards get detected, and I installed the drivers for them. No matter how many combinations I tried, couldnt get the 4th GPU up and running. After an hour's try, I got this idea.

I connected 1 GPU directly to the Mobo on 16x [Without blocking the 1x slots]. Then I connected my remaining 4 GPU using risers. Magically, 4 Cards showed up and then I found my screen flickering for a minute. Then, the 5th Card too gets detected. Now, all my 5 GPUs are running fine. If everything goes well for a week or so, then I will add 1 more GPU. Thought of sharing this in the thread.

Thanks

If you have 5 cards, why wouldn't you just plug 3 directly into the mb and use risers for the other 2?

Sure, bro. I will keep you posted. Thanks for your assistance.

I placed my mobo on a wooden board, nothing metal behind. Anyhow, I just sent the board for repair. And as per your suggestion, ordered 2 Risers Ver 007 from amazon. I will wait and see if that works.

Good call. It was probably just a bad board .. it happens. Feel free to send me a message once you get the board back if you have any questions. I have some similar mining rigs.

Yeah, I did set it to 4G before I insert the 4th card. I checked the version of the Risers. Out of 6 only 1 is Ver 006 and the rest are Ver 002. Do you think, this is the real problem?

You said the spark was near the 8 pin power connector? Isn't that on the opposite side of the mobo from the PCIE slots? If that is in fact where the spark occurred, it is most likely that you had something conductive (screw, metal shaving, screwdriver, etc) fall on the board while you were changing things out. This is usually how most boards get friend -- user error.

Of my riser failures, Almost all of them are 002. A few are 1.1. It's likely that one or more of yours are bad -- but I wouldn't blame them on the destruction of your motherboard just yet.

It did work with 3 Cards. And I could goto bios or boot to OS. I was perfectly fine. When I connect the 4th Card using risers? Mobo fried. Couldnt goto nowhere. Im not sure, I might have seen some kinda spark or something near the 8 pin. I was not sure because I have a lighting system to my aluminium rig so I might be mistaken. But it seemed so.

Did you set the mobo to 4G before you put the 4th card in? Not that, not doing so would cause catastrophic failure like you experienced, but I am just curious.

I have heard of defective risers frying motherboards -- while I have not personally experienced it. Usually when a riser is bad, it just causes computer crashes when mining. I have had probably 20+ bad risers and never once have they physically damaged my motherboard(s).

If you had a visible spark and can no longer get into BIOS, I would start working on an RMA return/replacement for your mobo.

Also, look at the riser boards for a version number. I have found that anything less than V 6, has a much higher likelihood for failure. When you buy from Amazon, look for ones labeled version 6 or 7.

Ohh Sorry, my first post. And thanks for your suggestions.

I tried, it totally fried. And I didnt touch the motherboard while it is powered on. What should have done to prevent this problem? Like, what I mean is, I have a good PSU, and this config is proved to be successful in many mining blogs. Then why isnt working for me? Even with 4 cards, MOBO failed. Then how come I connect 6 cards?

Just to clarify .. Does it boot with 3 cards or less? Can you get into BIOS with NO GPUS/Risers installed?

Sometimes you just get bad hardware. It happens. It's possible you did nothing wrong and the mobo was just a defect from the factory.

First, you probably should have posted this in the mining specific category. https://bitcointalk.org/index.php?board=160.0

Second, it sounds like you shorted your mobo out. If you can't even get into your BIOS, I would be fairly concerned that the mobo is fried.

I would remove all your risers and try to get into BIOS. Then I would try a different stick of RAM before confirming that the mobo is the problem.  

Risers seem to have literally zero quality control. I have experienced about a 50% success rate with them. I have a whole box of bad risers that didn't work right out of the package.

On another note: -- Why are you physically touching the motherboard while it is running? That in and of itself, is enough to destroy it. All it takes is a static discharge or you touching something that shouldn't be touched and you can destroy it. You shouldn't be able to comfortably touch any kind of active electronic. Even when the component is running "cool" (60-70c), that is 140-158 F .. AKA too hot to physically touch.

Once you get back into BIOS, make sure you make the correct BIOS edits to be able to boot with more than 3 cards: https://www.youtube.com/watch?v=4cd1qoTAHmA

Hello guys, its my first post in this forum. Hope to have a good time here.

Fine, I tried to set up a mining rig for Eth using the following specs.

MOBO : Asus Prime Z270A

Processor : Core i3 6th Gen

RAM: Corsair 4GB DDR4

GPU: 6X GTX1060 6GB

HDD: 1TB SEAGATE

PSU: Corsair RM1000X

Powered Risers from amazon. [Molex>SATA Cable]

Here's what I did. First I installed the Processor and RAM. Then I powered up the mother board using the 24 pin and 8 pin. Installed Win10Pro. Then insert the first GPU using riser, it got detected and I installed the drivers for it. Likewise, I did it for 2nd and 3rd cards. Then this happened. A strange shutdown, and Mobo is dead. CPU fan is working, but no power to other components. Not even booting to BIOS. I knew something is wrong. Couldnt tell what went wrong. Now, MOBO gets heated at a certain spot which I couldnt touch at all. Is this some kinda IC chip that I messed or something bigger? I have no idea about this. So, please help me with this. And tell me suggestions.
