I just placed an order for some g4600's. I will see how that works - the rig that had been crashing every couple hours crashed after 24 hours after I turned off teamviewer - hopefully this puts me over the top.

As for power, both are built the same way. Each is running on 2 750w EVGA G3 power supplies. Each SATA/molex power connector is running no more than 2 GPU risers. The molex connectors (and single SATA) hooked to the board each share with the riser for a single GPU (this means 13 GPU's, 2 motherboard molex, and 1 motherboard SATA to connect. The PSU's each have 3 SATA and 1 Perif (molex) connector, hence my using two connections per cable). I did have a 550w PSU in the mix (as a third) to see if that would change things, but it did not.

The only other discernable different is that not all GPU's are the same brand/make (but all are 1060 6GB), and the risers are not all identical (though I have switched them out in troubleshooting).

Good, G4600 is 2 core, 4 threads CPU. That will definetely help, much better than Celerons you have.

As for the mixed GPU's, try to put as many of the same brand/model in the same rig. Then you will have to manualy set overclocking for each GPU. Don't use the global OC for all. Try with the lowest stable value for all (I believe it was about 600 memory for you), then increase +50 memory on one brand/model and see if it's stable, then try +50 on different model and see if it's stable, then repeat until you get max for all models. It will take a while to fine tune it, that's the downside of mixed cards. Good luck and keep us posted.

Hi there nvoc-ers !

I may be stupid or definitely not paying enough attention to something as i can't for sake of me to be able to make AsRock H110 to recognize 13 x 1060 6GB GPU's. Tried with nvoc17, then 18, then 19..does not see the gpu on the last pciex slot.
It mines beautifully with 12 GPU's but there is no way i can make it see all the 13 GPU's.
The rig is built using a G4560, i tried using an i3... same result.
2 x Corsair 1000 W PSU's powering 6 gpu + mobo + risers and the 2nd powering 7 gpu's

Any hints ?

I struggled with this for a very long time. For me, it came down to a bad riser. I could have sworn I had tested and replaced them all, but this past weekend I started with one, and kept adding 1, one boot at a time, until I got to 13 working. I swear I did this a few times, but i find the pic-e risers LOVED to come loose as well, and may have had bad luck swapping a bad riser for a bad riser.

Aside from that, if you haven't, I would make sure the the 2 molex connectors on the motherboard are each connected to the separate power supplies.

Also, I noticed you have all risers on one PSU. I believe I have read that you should not have more than 2 per connector - I am unsure how many connectors are on those corsairs, but it might be worth trying splitting them up if you haven't.

Let me know if you get anywhere with this.

Another potential problem; that is often overlooked is slightly bent risers. If when you attach risers (depending on what kind of frame you are using) you place any (even slight, warping pressure (bending the front or rear of the riser sightly up or down while securing the other end) this will cause intermittent hard crashes. I have a rig that crashed last night: and I suspect this is the case with it.

Incidentally, what are the "best" risers out there - both from a type and seller standpoint? With so much that can go wrong in a 13 GPU setup, anything to minimize failure would be great.

"Best" risers seller dont exist Wink

Better to do is always buy more them you need in case u get one defunct !
I dont know all about this ebay seller, i buy mine on https://www.cryptomined.com/ a bit expensive people will say, but no one have fail actually.
