Mining Zcash with 6x Asus Turbo GTX 1080Ti

I am a noob when it comes to cryptocurrency and to be honest I didn't knew about DIY mining a month ago. And when I planned to start my own mining setup, I came to know that graphics cards are very difficult to find especially in a decent price. Then I thought that a lot of miner won't go for 1080Ti setup as its expensive to make, so I searched for 1080Ti and luckily I found 6 Asus Turbo GTX 1080Ti graphics cards.

And yes I am a noob as well when it comes to building a PC as I never did it before by my self. So I bought

. 6x Asus Turbo GTX 1080 Ti
. Asus B250F M.Board (The cheapest available in shop that supports 6 GPU)
. 4 GB DDR4 RAM (The cheapest available in shop)
. 120GB Lite-On SSD (Off-course the cheapest available in shop)
. 2x PSU Cosair 850w (If I knew a little more I would have bought one 1000w and another 850w )
. 6x PCI-e Riser
. Splitter Joiner (for dual power supply setup)
. 3 fans to help the system cool down
. 4x 4-Pin to 6-Pin connector for GPU ( as I came to new my PSU don't have enough cables for 6 GPU)

I create my setup, installed windows, create ZCash wallet in JAXX, then by following a simple tutorial I started to mining Zcash using EWBF mining client from zec.nanopool.org website.
At start I was getting approx 3600 Sol/s then I came to know about Overclocking the GPU, so I install Asus tweak II and it is the worst software for overclocking a lot of bugs. then I came to know that MSI has the best application for Overclocking and it works with any brand of Nvidia cards. So I installed it and started missing with the tuning the problem is that I don't know about my voltage usage. So it was kind of a blind tweaking .

Finally I started to get 4170 Sol/s by average from my 6 GPU setup. It some time go to 4200 but don't come below 4150. I think it can do better but I am waiting for Power meter to measure my voltage. but so far I am happy with my setup. I think PSU is the bottleneck, I will surely know once the meter arrives.

Yeah my system is ok but now as the ZCash price is very low its 0.09318 BT as I am writing this. so all the excitement is gone for now hope ZCash will bounce back soon.
