I can't wait to see Vega ...

I am about to buy 4 1080Ti  ...

You can buy those and make ROI before than vega will be available

In a most optimistic scenario they will be announced at Computex and will be available a few weeks after that.

Maybe something for the Christmas wish list ... months away ... Nvidia announce Volta, their answer to Vega:

spring  2018  for the 2080 ti version  save for it

Volta is not the answer to vega
Volta is a tesla card
Tesla cards are meant for servers
The price of a tesla card is stupid

My home setup

   
1x Intel Core i7 3770K Boxed
1x MSI Big Bang MPower Z77
1x Sapphire R9 290 4GB GDDR5 OC TRI-X

This is my setup, now i have opened an account at https://multibit.org/ and want to start mining for a time!
Ofcourse at the beginning it will not be the most avordable thing but with more and more GPU's etcetc hopefully better!!!

the 1080 ti  was based  on a tesla

the 2080 ti will be based on a telsa  the volta  so may next year the 2080 ti  will come out and be a big  step up.


mean while I am getting my garage ready for june rate increase and heat increase that comes each summer.

I am using 4.9 x 240 = 1176 watts  at the 240 volt pdu and 650 watts  at the 120 volt kill-a-watt meter a total of  1826 watts

I am getting 7200 sol of ZEC
I am getting   100 kh of xmr  some of the cpus are running it.
I am getting      8 mh of  x11   some tiny little   asic usb drive unit

about 45-50 a day  at nicehash

at  10 cent a k-watt  power cost is 4.33 a day
in summer at 20 cent power cost is 8.33 a day.

I am also running 70gh of sidehack sticks  which is a few more pennies a day income.

A 1826 watt in the summer is a bit too high for the garage I will be looking to alter layout just a bit  more.

dropping
one 1080    500
two 1070's  800
one 1060    300
total  sol = 1600

 adding 2 more 1080 ti's

total sol of 1300

  so 300 less sol 1 less rig  2 less cards  save maybe 120 watts

Hi guys hoping to get some feedback on my room plan:

https://i.gyazo.com/d73e124bf0a2ce32e0198c927a095e8f.png

#1 is my current plan: pull cold air in from the window and push them over rigs with fans behind each rig, then pull hot air out from the front of the rigs and use an exhaust fan in the ceiling to collect hot air and exhaust it out of the roof.  This should be sufficient cooling for about the ~105 GPUs I can fit on that shelving unit

HOWEVER! I would like to leave open the possibility of expanding in the future without having to move the exhaust fan's ceiling location. So I was wondering if #2 would work if I double my size. As you can see I'd be using fans on the ground to push the incoming air up at all the rigs but I'm unsure if that 15 ft (4.5m) is too much distance to hope to carry the air.

Fwiw, I'm dealing with 75-85 Fahrenheit (24-29c) ambient temps

Any thoughts would be appreciated!

[fullzero]

Ordered these; I will see what the problem is when I get them.

Not sure if you care but you can get the newer/better i3-7100 cheaper as it has a $10 off code

https://www.newegg.com/Product/Product.aspx?Item=N82E16819117734&ignorebbr=1

he got the 6100 on purpose to duplicate my board setup.

If he gets it running it is a good board as it can do 2,3,4 cards and is m sized.

which mean a very small 4 card cool build is possible.

I want to showcase a four card riser build with a m-sized board.

the i3 6100 and i3 6100 t  are pretty cheap on ebay and amazon used.

Phil,

With your GA-B250 rig:

I think you may have used the proBTC / tb85 image instead of the MSI 270-A by mistake.  In any case that one would only OC 2x gpus.

I made a new image for this GA-B250.

A bios setting needs to be changed:

Make sure Audio Controller is disabled.  This is the only bios setting I changed. ( make sure you do this before attaching the USB )

Sometimes the bios doesn't post after powering cycling the psu; if this happens press ctrl + alt + del until the rig reboots with a bios post.  

download specific GA-B250M__nvOC_v0014 image

unzip image

Image onto a 16gb or larger USB

configure oneBash

use with rig  

I had good results; made a video.

I would have used 1080tis, but I only have 3x; so I used 1070s.

Thoughts on this Mobo/cpu for a six card 1080TI ZEC rig?

Thoughts on this Mobo/cpu for a six card 1080TI ZEC rig?

I have one of these; they can do 6x cards if you change 2 settings in the bios.  see: http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

That deal is slightly expensive for a celeron cpu.  I use a G4400: https://www.newegg.com/Product/Product.aspx?Item=N82E16819117625 with my TB250

Hi guys hoping to get some feedback on my room plan:



#1 is my current plan: pull cold air in from the window and push them over rigs with fans behind each rig, then pull hot air out from the front of the rigs and use an exhaust fan in the ceiling to collect hot air and exhaust it out of the roof.  This should be sufficient cooling for about the ~105 GPUs I can fit on that shelving unit

You could probably get better temps using a duct to get the cold air as low as possible. That way cold air would be pulled up through the rigs and out the top exhaust. You could also split the ducts and have two cold air ports, one for each shelving unit. Just make sure you have more exhaust than intake, you don't want to positive pressure the room as this might disrupt the airflow. Also might want to suggest brillow pads on the intake just for light dust,debris filtration.

I don't mind paying a bit extra since Newegg charge too much for shipping to my Country.
Cryptomined ship out of China which should be cheaper for me. Also I can buy all the risers etc at the same time.

Thanks for the info fullzero...I want to run your OS on this build

Getting this as efficient as you can is HVAC math.  I'm good enough at HVAC to be dangerous, but I do my own work and haven't ever screwed anything up majorly.  Your most limiting factor is probably input and exhaust air volume of the room based on the opening sizes.  I'd calculate that first and then the fans you have pushing the air over the rigs may be an issue or a bonus, but if those are portable, easy to cope later.  You want input and exhaust as far away from each other in the room as possible.  Ideally you also input from near or in the floor and exhaust from the ceiling or very near as well.  Guessing is why most home cooling systems are inefficient, almost nobody nobody does the math, they just slam in a too big or too small system and cash the checks.

What type of fans are you going to use for input and exhaust?

My room is about 17x12 ft.

My window is 54x34 in and I was going to mount one of these 3150 cfm fans in the window (next to the screen) for pushing air in: http://www.homedepot.com/p/Ventamatic-20-in-High-Velocity-Floor-Fan-HVFF-20UPS/202795625

And this 5000 cfm fan for air exhaust in the ceiling.: http://www.homedepot.com/p/iLIVING-5000-CFM-Power-30-in-Single-Speed-Shutter-Exhaust-Fan-ILG8SF30S/207174738

I just learned its supposed to be a 2 to 1 exhaust:intake ratio so maybe I should find a slightly less powerful fan for air intake?

The fans I am planning to use behind each rig is the 550 cfm version of this fan, easily portable so yeah I can cope with issues pretty easily: http://orionfans.com/products/dc-fans/item/od254.html

In the front of each rig I was going to put a line of 5 x 180 cfm fans where the GPUs end

I didn't know the exhaust should be far away from the intake as possible. I thought I could put the shelving unit right by the window (close to the cold air) and use tarps to control the hot air side and try to exhaust it immediately right there.

Appreciate any advice!

the intake fan has 3 speeds  so set it on medium or low.

I suggest  making hot air guides with this

https://www.amazon.com/Car-Insulation-Deadener-Automotive-Lightweight/dp/B016QUS1YE/ref=sr_1_1?

many sizes.  

it will cut down noise
it will keep hot air contained
it is fire resistant

easy to use
a good scissor
a staple gun
some metal tape

https://www.amazon.com/Homemory-Aluminum-Inches-Yards-Furnace/dp/B01M7S4APP/ref=sr_1_2?


build this hot air/heat/sound guide  for under 200



I use it in my solar array

15 feet seems a long way for that window fan to push especially with a roof fan drawing from it also, kinda like short circuiting it. maybe runs some ducts from the window fan to the shelfs.

[JaredKaragen]

for the avalon and antminer style miners, I highly suggest heat/insulated ducting for the exhaust portion.

Not only does it reduce the whine/howl, but it allows you to precisely control the airflow from it.  I just used the aluminum air duct tape to seal it to the end of the miner's fan.  It worked like a champ.   Not only that, but if you got an air filter for a big diesel engine;  you could have an easy to clean/change filter on the air inlet as well.

The ducting cost was worth the investment in my opinion.  I was able to route the exhaust to an outdoor vent directly, and run an antminer in a closed space smaller than a closet without temp problems.

My first 10 x Antminers S5 and S7s was "hosted" at home and it was a nightmare - neighbors complaining about the the "jet" noise.

I tried the exhaust method, and later a "sound box" and it somewhat worked but still with 10 miners, the S7s were still heard "humming" even from a distance...

Now, my group's S9s and A7s are hosted in 2 x hosting data centres in Labrador, Canada where its bitterly cold 6 months in a year.

For my current GPU farm, I have plenty of room for exhaust.. will post pictures later.
