the difficulty also went even higher.... it takes longer now to get 5 coins payment from ethpool.org...

I am tempted to switch a rig or two to Nicehash windows miner and let it sell hash to the most profitable coin automatically... I get BTC directly from Nicehash too..

do you think its a good idea Phil?

good looking rig using the 911 watts is decent. for 140 mh.

I was looking at eth coin prices down to .0199 btc

I am glad my power bill has switched to winter rates.

wowow... reminds me of my first ETH rig, a 5 x MSI-390 150MHs monster, eats watts like nothing I have ever seen...  

that may not be an issue .

Thanks both for your tips!  I have just tried to update my drivers to Crimson 16.9.2. Downloaded that exact package from AMD and did Run as Admin on my W7 box.  But... when the AMD update box appears, the version next to AMD Display Driver, it shows the version as 21.19.137.1.  Shouldnt this say 16.9.2?  Has anyone else run into this?  I triple checked to make sure that I had downloaded to the correct update.

To upgrade your gpu from 20.5 to 23.5mh here is the youtube video to step you right through it.  Download the latest driver first just like Citronic said Crimson 16.9.2 then, I did each card one at a time in the slot that they would be placed.  Here is the video:

The copy of 1 of Win 10 PRO OEM DVD 64 BIT ENGLISH [ASIN: B01JM7NA76]  is not available anymore that I can find on Amazon.

Here is the pic of the Rig in the dark.  I moved it to the back of the basement and am building another one.

The upgrade is no longer free. That expired back in July, if I'm not mistaken

Second on that - just buy cheapest Win 7 on ebay and upgrade to Win 10

W10 is free..
there isnt a reason yet to buy a key for it

without rom modding, you can try this.
1. - ethi 16 (maximum ETH hashing using CDM)
2. Crimson 16.9.2

with rom mods:
At present, all my RX480 rigs are zapped with Heliox rom mods the lowpower29mhs version with 16.9.2, stable for weeks at 29.5-29.7MHs. In GPUZ, watts per card is 90s but actual should be more than this but definitely better than 150w. I can run 6 x 480s using a 1300w easily (1000w PSU can do the job).

This may be a good start.  The premise is the same.  Use polaris bios editor to tweak the memory settings.  There are additional tweaks you can make, but you run the risk of hosing your card.

Make sure you back up the original via GPUz, so you can always go back !

Yup... totally agree with Citronik, that rig looks sweet! And nice breakdown on the components and ROI.

I really like that metal frame you used... did you build that yourself or buy it somewhere?  If/when I build a 2nd rig, I wanna do it like that so I can easily move it around if needed.

In addition, can you share how you got these GPUs running at 23.5?  I have 3 of the exact same cards and they are getting 20.7 each using Claymore 7.2.  This is similar to the initial 20.5 you mentioned being the out of the box speed, but I am looking for the easiest way to increase the speed of mine up to the mid-20's like yours.  Was it something you did in the settings in Claymore or did you mod/overcloud the cards in some way?

Nice rig Aries - love those black and red MSI stripes - take a photo with lights off, you could see that MSI dragon badge..

BTW, where in Amazon can you buy Win10 for 25 bucks?

Equipment:

6 MSI RX 470X GPUs........................................................................$ 199.99 (20.5mh out of the box)
2 Antec 750 Platinum PSUs...............................................................$ 130.00 (you can find some good deals on these)
1 Motherboard = MSI Z97 Gaming 5 (LGA 1150).................................$  97.00 (found in returns-normally $150)
1 Micron M600 128GB Sata III M.2 SSD.............................................$  32.00
1 Ballistic 8GB Kit (2 4GB) DDR3 1600 RAM........................................$  32.99 (discounted when buy with motherboard)
1 Intel Celeron G1840 Processor (2.8GB, 2MB Cache LGA1150).............$  34.99
1 Windows 10............................................................................. ....$  25.00 (bought on Amazon)
1 Super Multi DVD Writer.................................................................$14.99
2 3/8 Aluminum Plywood Trim (Lowes)..............................................$  8.98
2 1/4 Aluminum Plywood Trim (Lowes)..............................................$  5.98
1 1/16in x 1/2in x 3ft Angle.............................................................$  2.18
32 #8 x 3/8in Screws.....................................................................$  2.00
                                                                                          Total  = $1628.07

Output:

-total system hashing  = 141.2mh
-each gpu hashing  = 23.5mh
-ave wattage = 77W (range 68-81)
-total system Watts = 911W
-total system Amps = 7.73A

Here are pics of the Rig:  










Here is the Profitability:

ETH = $13.00
Cost for the Rig: $1628.07
Warranty GPU & Motherboard: 2yrs
Profit/day:  ~$7.42
Usage: 911W

Calculation for Daily Power Usage and Cost of Electricity.
Electric Cost = $0.12 cents per KW
911W / day = .911KW
.911KW x 24hrs = 21.86KW

21.86KW x $.12 = $2.62 / day for the cost of running .911KW of electric.

Profit = 7.42 - $2.62 = 4.80/day
4.80 x 30 = $144/mo

ROI = 1628.07 / 144 = 11.31 months ROI

Notes:
1. If you buy all of this on Amazon using Bitcoin on Purse, you can get it 20% off = Grand Total of $1302.46  ROI would be 9.04 Months!
2. If you get better electric rates, you would be more profitable!

I like the Biostar mobo -- nice touch sensor switch for power/reset/turbo too.

I was really surprised that the box it came in is so "fancy" and expensive looking - unlike ASrock H81 Pro BTC 

I had purchased 20 coa's  from a recycler.  So my cost to run windows 7 pro was cheap.

The biostar z170 builds are very compact units for 95-100mh at 600 watts or so.

https://bitcointalksearch.org/topic/my-second-zec-xmr-eth-thread-builds-info-links-thoughts-and-photos-1584973  from first post in the thread




it is rig1 doing about 95-96



the goal will be the three z170's on this rack from

target.http://www.target.com/p/adjustable-3-tier-wire-shelving-black-room-essentials/-/A-13892292?

they will mount here we extended the loft  in the solar array so they will face that fan  we also cut back on the s9's in that photo  we had six we now have three

Phil runs W7 so I see why now you can run more than 4

In progress actually.
I have 6 x 480 on W10 that I will be attempting to convert to 8 x 480 using 1600w PSU and Ubuntu Linux 14.04
The 6x480 rig is modded with Heliox 29MHslowpower rom and just over 1100w on W10.
I am waiting for the PCI multiplexor to arrive,  2 x 480s have already arrived.
I hope the Linux build stablize under 1600watts.

have you tried 400 series cards tho? its a completely different card than the 300 series.
from what i been told it can only support 4 400 series cards.

I have 7 x 370s on Asrock H81 Pro BTC, the last PCI slot with a 3-to-1 PCI multiplexor.

First 5 slots with PCI-USB3 risers and the multiplexor can handle 3 slots, which only 2 is used.

I am using Win7 and it can drive 7 cards. Windows Advance Server with some registry hack can do 8 x GPUs.

From the Ethereum forum, a dude shared with me that he got 8 working on Ubuntu.

Note: Powered molex on the mobo and also powered USB risers needed to make it work. Rig working very stable for months now after changing the PSU from 1300w to 1600w EVGA-G2.
