Fourth alt coin thread last three got oversized.

[xleejohnx]

Finally broke and got some 1080ti
Been testing one and got at 690-710sols at 200watts 3.47sol/w temp is 72c in a 95f room
Does that sound good or do I need to play around some more?

[TheRider]

Okay I just setup  a 2x 1080 ti + 1x 1070 rig riser free.

Can you please show a top view picture to see the spacing?

yeah I just took it.

if you use the gigabyte board

[TheRider]

Thanks Phil.

Btw, have you ever found a mobo with 1 4 7 spacing between the PCIE 16x slots?

[VyprBTC]

Phil you're awesome!

I have some of those motherboards on the way, also I have a z170 with 4 PICEx16 - spacing is going to be tight for a 4 card 1080TI no riser but I'm going to run it just to see how long it can go. Should get here monday.

My new bottleneck - these stupid Corsair 750's only have 2... TWO! 4+4/6+1 power ports. The Rosewill 850w you suggested does have 4 PCIE power lines, so I just need  to get some more cables that have 2 sets of 6+2's in them, I ran out. I upgraded a dozen 1070's to 1080Ti's today - hardware always takes longer than you expect. Was expecting to unscrew, unplug, swap and be done. The power cords threw me for a huge loop.


I was thinking about running power from my 1500w EVGA but I actually don't have long enough cables for that either.

So back to the drawing board.

the gigabyte board will do 3  with no risers.   1080ti 1080 ti 1070 mini

here are two builds on the biostar z170

This EVGA GQ 850W has EIGHT 6+2pin. You could technically put 4x 1080 Ti on that Biostar mobo.
Just make sure to get the blower versions of the gpu and lower the power limit to around 75 to 80.

I ran the biostar z170 with 4 rx 480's no risers it gets hot

the setup I did with 3 cards  above is pretty much fool proof zero heat issues  2300-2400 for skein only 550 watts.

it will run on  the biostar z 170

it will run on the gigabyte z270



https://www.amazon.com/gp/product/B01N2V0AHI/ref=oh_aui_detailpage_o00_s00?


2300 for skein  or 1800 for zec  low power  550 watts

all three cards cool.

Since I have lots of biostar z170's I will use them.

as for better boards no board  that I know has 1-4 -7 spacing.d
but the 1080ti - 1080ti - 1070 msi mini  super short   allows for 3 cool cards. 72-75% tdp's

 my garage is hot 90 f

cards still run well under 70c at 75% fan.

my rack can hold 6 rigs that would be  more then 6 x 2200 = 13200 for skein or  6 x 1800 = 1080 for zec  at 6 x 550 watts = 3300  

I would be earning over  150 usd a day for that power.


btw  the evga psu you link is a good one for one of these rigs.

I own 2 and ⅓ s-9's  they use about 3300 watts  they earn 33 dollars a day  


same power bill   at 20 cents a k-watt about 16 dollars a day.

so  one setup earns  150 cost 16 to run at 20 cents a k-watt  cost 8 to run at 10 cents a k-watt cost 4 to run at 5 cents a k-watt.
one setup earns 33 costs  16 to run   same as above.

basically these gpus  compete at 20 cents a k-watt  as well as s-9 do at 4 cents a k-watt.



I plan to have 6 rigs on that rack

1)1080ti 1080ti 1070    4)1080ti 1080ti 1070

2)1080ti 1080ti 1070    5)1080ti 1080ti 1070

I bought 4 rosewell 850's yesterday, I might return them and get the EVGA's I really like the looks of them! Thanks for the link scryed

Also the 2x1080Tix1x1070 is pretty nifty, I might have to try that out! Space is getting crowded with all these 2 card rigs I need to bump up to 3+ ASAP.

Ordered 10 more TI's today. 10 Yesterday. The inventory is growing.

I used the rosewills  they are good.

I have not used that particular evga.  it has a nice price.

I need to see all my mobos  to figure how many

2x1080ti's
1x1070's

I can build.

the heat on them is good.

I have 1 more 1080ti and 1 more 1070 coming

I will do a third build like this.

giving me three riser free builds.

that rack is 18 inches deep and 36 inches high

fitting  6 mobos and 18 cards will be easy

in the winter I ran  6 mobos with 24 cards  but they ran hot.  about 7200 sols for zec and  the panda miner did 2200 = 9400 sols  22 amps of 240 volts = 5280 watts.


I now do  10 amps x 240 = 2400 watts  and this would be 8000 sols  I have to stay low watts for summer.

is that due to heat?

I could not run 5 2 card no riser computers in a room, what I had to do was stack them up against the window and have the GPU's blow out the window. It literally fills the window sill from top to bottom - my neighbors have already come by asking me wtf am i doing lol.

They know I'm up to no good - I had 50 Time Warner Cable ISP connections at my house, 50 wifi routers on 50 different cable modems and lines, and it knocked all the wifi from a 3 house radius out - nobody that lived 3 houses in any direction from me could get a signal. That went on for 3 years. They're still upset, but don't 100% know it was me.

[QuintLeo]

Thanks Phil.

Btw, have you ever found a mobo with 1 4 7 spacing between the PCIE 16x slots?

 They don't exist on any board with only 3x PCI-E slots - I've been looking for a couple YEARS now.

 I think I remember seeing *ONE* 4-slot board that could achieve that spacing, but it has been out of production for a while - really old Intel chipset IIRC.

 Quite a few 5-slot boards can achieve that spacing, but they start at "expen$ive" and go up from there.


 The 3-slot layout like Phil's Gigabyte motherboard is COMMON in both AMD and Intel, and can be commonly found in the $100 range or under with some digging, though sometimes you have to go with a "on sale" board to get there.

 I prefer the Gigabyte "ITX" 1070 for the 3'd slot from having used a few of them, but Phil's MSI "super short" is the same length and should be just as good at letting the middle card stay cool - it didn't exist when I built my first pair of 3 card rigs with the Gigabyte, and by then I was in the habit of using it.


 At the 850 watt level my go-to power supply is the Seasonic X-850 but they appear to be out of production and availability is getting spotty. My second choice would be the EVGA G2 850 but it also is going or gone out of production....

[cvsea]

You guys are getting ridiculous prices as far as us europeans are concerned. Over here you can't even touch a 1080 ti without at least $850 not to mention other vital components like a good mobo.

Might consider getting back to the US. Any of you want to adopt a 30 year old?

On another note, is it me or is skein ridiculously profitable right now? My one 1080 ti is about $2 shy in earnings/day than a 4 x amd rig. DGB price climbing as we speak.

[QuintLeo]

here are two builds on the biostar z170

 The spacing on your Biostar Z170 boards is such you could probably get away with an Aorus as the slot 1 card (or that MSI "2.5" slot 1080ti since you seem to prefer MSI as a general rule).




 cvsea - only way I'd consider adopting you is if you were a pretty gal. Sorry.

Finally broke and got some 1080ti
Been testing one and got at 690-710sols at 200watts 3.47sol/w temp is 72c in a 95f room
Does that sound good or do I need to play around some more?

Those are good numbers, I run a bit less power than that and try to get minimum 3.8sol/w. I get around 650 sols.

Guys what would be a good power supply solution for 4 pico 160 watt PSU's?

Can I get away with one power supply to feed all four Pico's or do I need a separate supply for each pico?

4 picos off 1 psu .  I guess that could work.

next question  what else does that psu do?

there are breakout boards for the ibm 2880 or 2980  they have 20 pcie  cables

finksy sells them in north america

[bentcrypto]

next question  what else does that psu do?

Ive got 2 of these 2400w server PSU's already : http://www.parallelminer.com/product/delta-2400watt-platinum-94-efficiency-power-supply-208v240v/

My plan is to run 4 rigs with those two server psu's and 4 pico's. I can use 4 small power adapters to run the pico's, just looking for an easier way (1 plug in the wall).

Would a higher wattage version of this work?

okay attach pico to big power supply.

run 1 test if good do 2 pico
if good do 3
if good do 4

Phil, appreciate all the effort and time you put in to share your knowledge.

Almost pulling the trigger on my first build, shopping list if you can see if I am forgetting anything:
-2x MSI 1080ti FE
-1x Zotac 1070 Mini
-1x EVGA 850w Gold
-1x Gigabyte GA-Z270P
-1x Intel G4400 Skylake
-1x Crucial 4GB DDR Ram
-1x ADATA 128GB SSD

Puts the tab around $2.1k from Newegg, little more than your parts list from another thread where you were at 1950 or so.
