That's funny I just asked about the orientation of the cards xD
Power draw on the 1070 vs the 1080?
Per the price do you find the 1080 to be worth it vs the 1070 / about the same? / 1070 better value?

 note correction made

 the 1070 mini is 350 at newegg

the 1080 mini is 500 at newegg

so left to right:

msi aero 1080 ti --------  msi aero 1080 ti ----------- zotac mini 1070  or 1080


and here is a great psu to run 3 cards  very good price.

https://www.newegg.com/Product/Product.aspx?Item=9SIA07236V1499

these are really good  do not worry that they are rosewill  they are a higher quality psu

They are around $500 so about $200 cheaper than the 1080Ti's

Is 1080 half price of 1080Ti?

I have four of those aero's  they are pretty good.

is really easy to run  no risers very small size  allows multiple rig locations and multiple coins mined.  keeps cool.


if you want an upgrade  use this board

go

 aero 1080 ti
 aero 1080 ti
 zotac 1070 mini

the short zotac 1070 leaves room for the middle aero 1080 ti to breathe  this rig will do  650 + 650 + 400 =  1700 zec  at 500 watts  which still allows for  the evga 750 p2  psu

this is about

1400  for 1080ti
  350  for  1080  1070 mini
 110   for   mobo
  40    for   ssd
 110   for   psu
   35   for  ram

2150 with no sales or deals     I think a pandaminer is now  about 2500 shipped to usa.

this will do say 1700 sols for zec  at 500 watts at kill-a-watt-meter   and be quiet .

the panda miner will do 2300 sols at  1100 watts maybe 1000 watts and be loud

Yeah, I have two of each, Samsung (8G) and Elpida (4G) variants.   Their hash rates are about the same ~27MH/s.
Nothing fantastic, but they are consuming 105-110Watts each.
Even if you are not familiar with BIOS editing, it is really easy.
Get a copy of the current bios from the gpu with atiwinflash (assuming Windows here) and save it to a backup file.
Open the BIOS file with HxD hex editor and search for this string FF 00 01 07 0C 00.  Then verify that the 4 bytes immediately before this string is
8D 00 xx yy.   Use editor to modify xx yy value.   Say you want a 50mV undervolt, then assign xx yy = F8 FF.
(reason: F8 = -8.  Multiplied by 6.25 -> -50).   Ok, do not change anything else.
Save the file as bisomod1.rom or some such, then reopen the file using Polaris Bios editor. Then save the file so that the checksum gets updated.
Use atiwinflash to flash the card with this bios. Enjoy!

One thing with the 470s, My cards all have different bioses.  They are really different on what they accept wrt amount of undervolt, memory overclock amount etc.
Therefore, try a low undervolt value initially.

 4 card rigs are a lot harder to keep the GPUs cool, unless you use risers.

 I personally prefer 3 card rigs, but current motherboards are either WAY too expen$ive to get proper 3 cards spacing for good cooling on 3 FULL LENGTH boards, or I can use the low-cost stuff and make a point of putting a "short" card in the 3'd slot (like the Gigabyte "ITX" 1070 model) to allow the middle card to have ONE fan completely clear to keep it cool enough.

 3 card rigs are a LOT easier to set up then riser rigs, in my experience tend to be noticeably more reliable than riser rigs (riser rigs ARE easier to keep the GPUs cool on though), and the cost difference is very small to nothing after you factor in the cost of the risers, the extra amount of connections needed on your PS (or the extra CABLES to add to it) to power the risers, and the problem that power supply cost per watt starts climbing noticeably faster past about the 650 watt level vs the "additional costs" of 2 MB, 2 CPU, twice as much RAM, 2 HD/SSD/USB keys.

 You also get the nice part that if you DO have a rig go down, you only lost HALF of your hashrate from 6 cards instead of all of it.

 If I could get reliable access to that Katana-model 1070 or if someone that DOES normally sell to the US builds a similar model at a SMALL premium to 2-slot card designs, I might start going 4-card rigs regularly, as THOSE things you can keep cool fairly easily on boards like the Biostar Racer board that Phil liked that have 4 slots properly spaced to mount double-slot cards ON the motherboard.

 NVidia and AMD make "compute" single-slot-wide versions of many of their higher-end GPUs but those things are CRAZY expensive definitely not a good choice for a mining machine (unless you can get a good used one for a LOT off new pricing).


 The really scary part - as of this morning, the only RX 4xx boards I could find for sale anywhere (I do NOT look at eBay, too many bad experiences there) were all priced HIGHER than the low-end of the GTX 1070 - and the RX 5xx cards I could find weren't much better.
 We might see a big short-term move of folks to NVidia because the "lower cost" part of the ROI question on the RX 470/480/570/580 isn't THERE any more vs the 1070.

the rig does around 1050w -- 27.xx MHs per card

if you know how to better this ... I am all ears 

my Sapphire cards are mostly Elpida memory.
Some Hynix and Samsung.

Citronick,
that is a lot of Watts for those 6 RX470s there!  
You *should* be able to achieve a 200-300W reduction by proper undervolting (in BIOS if you are using smOs).
With the Sapphire cards, a BIOS mod to undervolt takes like 2 minutes.

re-emphasizing dream..... after the BTC blood bath yesterday.... that 3rd GPU farm will remain a dream for now.....

I have a hunch that if we start our 1080ti ZEC project early..... we will be a few steps ahead than the rest of the AMD boys.... especially the correct boards, config and tweeking for a proper NVIDIA ZEC farm

whats your review on smOS and nvOC // esp vs using a windows setup?

What MBs would you rec w/ nvOC?

Phil - I like that Gigabyte Z270 above, I will get a few to use .... the old Z170s are PITA on smOS and nvOC... I am moving away from those Z170s eventually. 

My dream (maybe GPU farm #3) will be all NVIDIAs -- rows and rows of Aorus 1080ti and Zotac 1070 minis !

what prices are you getting the 1080 TI at? If you dont mind me asking

Why 2 vs 4 card rig setup? Why do you believe this is the best setup, just asking because I'm curious and want to build a 1080 TI rig

Furthermore, what is reported to be the best 1080 TI card?
https://www.newegg.com/Product/Product.aspx?Item=N82E16814137115&cm_re=nvidia_1080_TI-_-14-137-115-_-Product I'm partial to this because it has green xD

Definitely good help can be found here! 

Awsome!!! You got indeed the same support as me to put on your rig. Hahaha

Well done!
