Why Stop @ 7 GPU mining Rig.

I am building a 18 GPU Mining Rig with the following bad boy:

 Grin Grin

you already know this article? https://bitcointalk.org/index.php?topic=64450.0

600 USD from his source, or near double - so 1200 USD directly by trentonsystems..... i think the starting invest just for a board is to high. for 100 USD each i get a 5 - 6 GPU supporting Board. so with 500 - 600 USD i will get 25 - 36 GPUS.

Just CPU and RAM you will save a little.

I have Ordered 4 of these: https://mineshop.eu/cables/pcie-adapter-1-to-3-slots-detail

still waiting for testing if they are supported by SMOS. I have already made my Rigs with a 1700 - 2000 Watt PSU system. so it would be great if these extenders would work. Unser Windows they are already running. but still dont know about linux support.

I have 7 x R9-Nano rig working with smOS and SRR perfectly, with this PCI splitter.
The Nanos are can mine ZEC up to 420-440 sols/s per card with Optiminer v1.7
The rig is powered by EVGA-G2-1600w PSU and current draw about 1150watts with 1000/500/-20% power-limit.
Previously the Nanos are with -100mV undervolted custom rom mainly for ETH mining but the Nanos are best for ZEC due to HBM and 64 compute cores so I flashed it back to stock rom and -20% PL to manage the amps and the 7xGPU config with lower but stable sols/s.
BTW, using this PCI splitter, only 7 GPU ok, 8 GPUs not OK or I dont know how to make it work.
I have asked around but 7 x GPU is easy with Linux.
Anything beyond that need some special hacks and special drivers; and goes into the realm of deep learning systems.
This 16 x GPU rig monster is an exciting project but probably not practical because it's too expensive.
Imagine the monster power supply to handle this rig, and keeping it stable.
The risks of having too big of a rig is huge power consumption and a big drop in hash when it's offline for any reasons.

51MEGATRON is the 7 x R9-Nano rig currently mining ZEC, stable at 370-390 sols/s per card.
"51" is the SRR locator. SRR#5, slot#1
Pix below is the "R" rigs list. There is another list for "RX" cards separated by using a different email.

Thanks man for sharing your experience in Detail. Helps alot for thoughts. Still have to wait for arriving.

In Summery we have to time 6x R9 290x & 10 RX 470 (Brand mixed for study. To time running in 3 boards. Want to decrease the need oft boards.

Wie are expecting the New awesome dashboard. Hope it gets released soon.
