Fourth alt coin thread last three got oversized.

Maybe this will show other manufacturers that there is a market for thin cards.  There are no one-slot AMD cards, save for a 460 here and there...

He is using palit cards one of the best made cards on the market.

The Galax Katana 1070 has sold out.   I only have 1 and 1 on order.

It is what happens when you post a nice thread  some whale looks at the work  and buys out all the hardware fucked again.

I think I won't be posting for a few days.

Panda

Now this.

Here's what you should do going forward Phil.

Get one, test it and see if you like it. If you do, go back and buy however many you think you want, THEN post the nice reviews online.

This way you'll have secured yours and let other people scoop up the remaining stock.

Can someone recommended settings for 1080ti?

I have a 6x 1080ti rig, each running 60% power limit, +250 core, -500 mem (mem oc or underclock, no hash difference).
Getting only about 600 sols and 4sol/w. 900w at the wall for about 3600 sols. Voltage is unchanged.


It seems low compared to gtc 1070 which can do 450sol at 60% power limit. Should I undervolt?

[jenifive]

Its about 63%. I think i can make it even lower. Also i noticed if i will make i little change on memory clock on same GPUs it will work a little more stable.



So im having

- 40, 90, 670
- 40, 90, 660
- 40, 90, 650
- 40, 90, 670

With this rates im having 540 watts per 1x mining farm.

It does not effect on sol rate, but effects on stability of this 4x cards.

I know;  after seeing the hashrates out of just 5x 1080's, I can only imagine how the ti feels when you get the pools payout 3 times a day... lol.

Thats a $6K rig .. hope the rig can touch at least 5000 sol/s

[delicopsch56]

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!

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!

In a closed room, yes, you want BOTH those rules goin on if you can.  I think I'd put the heat generator right smack in the middle of thee room.

The home depot cheaper fan, spent that kinda money on fans and ran em 24x7 and dead in 2 years or less  That's why I turn my wife's off every morning. Ain't no wind tunnel.

Go stand in front of 3500 - 5000 cfm fans at home depot or lowes, get 'em to plug em in for ya.  I don't think you'll be real impressed.  Ain't no wind tunnel.  Could be enough but won't know without including size of openings and cfm in the calcs, and prolly also BTU or estimate, avg ambient air temp outside and inside with no heat and cool running at all, etc.  Attic fans are awesome IF you open every window in the house, yer air isn't dirty, and you have a high temperature differential inside versus in. Like 20-30 degrees. That one is not much more expensive than a good bathroom exhaust fan nowadays.  I think you are mostly paying for the metal there.

It could work but you don't wanna overspent or underspend to get the job done.

Most HVAC forums are filled with tradesman that don't really like to give DIY advice in varying degrees but since you aren't working on a furnace or an air conditioner at all they may point you right at the correct formulas if you include all the measurements mentioned in this thread.

It seems low compared to gtc 1070 which can do 450sol at 60% power limit. Should I undervolt?

I have a pair of 1080ti FE's in a closed rack mount case and they get the following:

Power limit of 50% gets me ~525 sol/s and 4.2 sol/W @ 120W per card
Power limit of 60% gets me ~620 sol/s and 4.1 sol/W @ 150W per card
Power limit of 70% gets me ~670 sol/s and 3.8 sol/W @ 177W per card
Power limit of 80% gets me ~700 sol/s and 3.5 sol/W @ 200W per card
Power limit of 90% gets me ~725 sol/s and 3.2 sol/W @ 220W per card

It seems to me that these 1080ti's love core clock, and memory speed really doesn't make that much difference. I also found -300 mem was good

What core oc are you doing in those benchmarks?

And ya seems like mem clock doesn't make a difference, does -300 just save heat/power?
