A little more gear anyways. Am pushing to get this custom miner rack going....looking like 16 rigs per rack will be optimal for fresh air intake and hot air exhaust. Thank you very much for those dimensions you got me!

I cracked and sold a coin today for about 976.
so far the dual mining has been stable.
Decred has dropped to about 17 usd still can't complain is has been a good 14 hours of dual mining no issues

Apparently, two of my rigs don't have enough head room to sustain the extra power draw. I need to move some PSUs around.

If so that's not bad at all

@Phillip I can't bring myself to sell my BTC... I feel for ya. Every time I absolutely needed to sell some (to make ends meet) it was always a heart-ache and painful feeling. The last thing I want is FIAT in place of my BTC.
Just spent the last entire night (8PM-now PST) assembling a 6 card GTX 1080 rig. We had originally agreed 1070 would be the best fit, but with the recent price drop, he went ape$hit buying up all the used/open box 1080's he could get, he even haggled Amazon down on the 2 rack cases (minor defect or refurb cases).... But it was a surprise when I saw a stack of 1080's last night. I had to take a photo holding a stack of 6.... lol.
We are using one of the $99 EATX rack cases that a forum member builds professional cages to hold the video cards, ASRock H97 Anniversary, celeron something or other and 6Gb ram, 120Gb SSD, the new PCIE style [right angle-1x male connector and PCIE +6 plug] risers, Coolmax 1600w power supply (it was donated to the project by a friend of his so its being used).... And 3 EVGA GTX1080 (2x FTW and 1x SC), a PNY reference card, and the last is a brand I don't recall the name of, which is a reference style, but their own design of the typical nvidia one.
We did it all simple; a rivet gun and some L shaped aluminum strips as well as a U shaped piece, and a hacksaw were used to support the risers. Everything was hooked up correctly, no shorts to ground, etc... all secure with rivets.
I'd have completed photos, but 4 of the 6 risers burned out as soon as we powered it on. Very odd. if you lift the foam under-padding to inspect the bottom of the riser, the whole +12V rail leading from the PCIE pins to the PCIE connector is fried like a fusible link... and separated from the substrate. At least 80% of the entire physical trace on the underside. Anyone had this happen to them?
the 2 other risers work perfectly fine. A strange issue indeed.
All in all, crude, but frugal and effective. He bought a second case just because they were so cheap.... so we will be doing more miners in the near future. If it all works out, we may be able to snowball into buying more and more cards and grow a business together. Who knows. I hope the alt market stays this profitable. I am seeing 2x+ profitability recently with the algo I have been mining the past few months.
So for now; we only have 3 cards online (one is occupying the 16x slot); and the first 1070 in his home PC chipping away. I am returning later today with 2 of my personal risers so we can at least get the other two idle cards installed ASAP.

I tried to run 7 GPUs successfully with h81 pro btc and pci-e 3x splitter , with SMos. Thank you for the idea. Cheaper than a MSI gaming 5.
Have you ever tried 8 GPUs as the splitter has one slot left ? maybe Simpleminer could handle it ?

Do someone already have this issue with claymore : " can't allocate big buffer for dag" ? and know how to avoid ??

Does your card have at least 4GB of memory? Are you using 64-bit pointers in your batch file? setx GPU_FORCE_64BIT_PTR 1setx GPU_FORCE_64BIT_PTR 1 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100
cmd /K EthDcrMiner64.exe -epool us1.ethpool.org.......

Cant do 8 ... somehow it need some funky AMD Linux driver - gave up trying.... its certainly possible (see jstefanop work on 16 x GPU systems) ...because you need a powerful PSU to support that kind of rig, unless you explore the server PSU setup like what yun9999 and yslyung are using. Anyways, I steer clear of monster rigs because that poses additional issues like ensuring you have enough amps in your power rails, cooling issues, etc. If the rig is down for some reason, it will be a big hash drop. I rather spread the GPUs in a balanced mining strategy -- and easily achieve a more cost efficient multi rig deployment.

cmd /K EthDcrMiner64.exe -epool us1.ethpool.org....... Thanks LoneRangir, yes it is a 4BG card (rx470) It appeared in Simple Mining OS , so I don't have the " setx GPU_FORCE_64BIT_PTR 1" sentence but should not be a problem. The issue appear sometimes. I have to reboot and generally it works again. Maybe some setting to improve ? -eres @Citrionick : ok thanks for saving me time. Won't try 8gpus !

Started up the array with 1 test rig Plans are to move most of the gpus to the array will take a bit of time to do it.

Any idea ?
