Hello guys, I would like to share how it's going with my setup since you been really great for me as indicator to what to do or not.

By now I've got 3 nvidia GTX 1080 TI and a nvidia GTX 970.

And here's a screenshot how my ZCash miner it's going.

After much testing I've got this results and since here power bills are kinda expensive I don't go full power, but instead I went looking for a good Sols/W rate.

Does anyone know why always the last GPU does have better Sol/W rate? I've done a lot of testing and it's always happening to me. I don't know the reason but always the last card on the rig does consume like 10% less power doing the same hashrate. Check if it's happening to you also.
Of course all NVIDIA GTX 1080 TI are sharing the same settings.

If you got some tips to improve Sol/W, or lower power consumption from other components please share them

I will check, what miner are you using? I don't know how to get that efficiency table with ewbf-zec

What settings are you using on your 1080ti? Looks like you have TDP down quite a bit but still getting good sol/s

I had the same question

FWIW I have used ribbon risers before.

As long as they have their own power cable to power them, id say they are useable.

They aren't for systems that will see lots of movement or be taken apart a lot.... They are very fragile compared to the typical powered risers.

@Phil, One of my Diamond RX480 ref cards died. Sent it back, they got it yesterday, checked it out, and sent new one out today. Pretty good turnaround.
And sure appreciate you handling the escrow for me!

@phil
i really like the two card design you have going on. reminds of the milk crates miners back in the day

are you equihash only now? or is that because you have mostly nvidia now?

'The right to privacy matters'

Wood rigs cheap and easy to make and are great if you never have a burn out.

So good psu's and don't tax them at 90%

good risers
good wires.

and great fans to cool the gear down.

lastly do not run the gpus pedal to the metal.

look here two gpu rigs only 4 cards as I am finalizing my solar array with buysolar for the next 5 months

I added this one today.
the silver is a fire barrier as it works in car engines .
it is a wind tunnel
it also sound proofs
I added the 2 gpu one

here it is hashing but not maxed clocks

put it on the car before I drove it to the array

and in the array running. the array will add a few more gpu rigs and 1 s-7 three avalon's 721's and ⅓ of a s-9

Have you guys found using wood rig frames has any affect on room cooling vs using aluminum frames or whatever?

I dont have a ton of rigs but I dont think something like this would really matter. Best answer to this is to look into the thermal conductivity of the type of material your rig frame is built from.

K Value (therm cond)

Aluminum = 205
Wood = 0.12-0.4

So obviously the thermal conductivity of the aluminum is much much better. The wood will retain more heat and swell much more than than the aluminum however it is not electrically conductive (mostly Wink

)

Probably more important in the wood vs aluminum debate is thermal expansion. Linear growth coefficient for aluminum is about 23 and for wood it can vary from 54 to 27. So wood rigs will "swell" more than the aluminum frames.

Aluminum rig Pros:
Frame strength
Corrision resistance
Better thermal properties

Cons:
Electrically conductive
More expensive
Harder to make

Wood Frame Pros:
Cheap to make
More simple to customize
Won't conduct electricity

Cons:
Will expand and contract more
Can rot, bugs, absorb moisture
Could catch fire

I'm a cheap skate so I go wood build and have always used this guide because I can make them in 20 min.

'The right to privacy matters'

Quote from: ?? on ??

What I like about the GTX9, is you could use full ribbon risers to have a clean rig with space.
my ? are ribbon risers better then power risers? Huh

That should be GT9. I had GTX 1080 Ti on my mind. Grin

ribbon riser = bad
powered risers = good

Quote from: ?? on ??

Another ?. when the Vega comes out, would it be better to use a AMD mobo, or a intel Huh

?

don't know as a high end AMD cpu = $$$ but it may mine xmr well as the vega mines zec or eth

Quote from: ?? on ??

Another ?. I'm looking at the GTX 1080 Ti. The price range from 1 fan (lowest) to 3 fans (highest).
If you factor in spacing, can you benefit by 1 fan. or am I missing something? Huh

.

so far I think I like msi aero 1 fan cards

founder edition 1 fan are not as good.

I have 1 3 fan gigabyte aorus it is too wide.

BTW please do not multi post 2 or 3 or more in a row. I deleted them for space.

Thanks again for putting the need for spacing into perspective - the GT6 board would be ideal with enough spacing; its cheaper too - thanks Phil

I want to buy it I really do but newegg is charging a lot

https://www.newegg.com/Product/Product.aspx?Item=N82E16813138439

and sticking in an ssd that I do not need.

this one appeals more to me

https://www.newegg.com/Product/Product.aspx?Item=N82E16813138441

it may do 7 and you can start with 3 cards in slots earn money and add risers later.

Im liking that board better personally. Most of the time, if you go over 3-4 GPU, you'll want risers and better spacing anyways.

If I buy a newer generation board, I may go after that one....

this is very good does five with a mix of slots and risers it is low cost 108 rebates drop it under 100

It most likely does six I have been lazy and not tested six. but 3 asus strix and 2 msi gamer rx 480's all 8gb running zec at 1500 sols using smOS pretty much perfectly

yeah the 1080 ti can push 4 sols a watt

tdp or power can drop to 50%

once you go over 75% the sols to watts drop a lot

They all have different sweet spots..

I have

3 msi 1080 ti aero https://www.newegg.com/Product/Product.aspx?Item=N82E16814137115 my favorite one so far

3 zotac 1080 ti founders https://www.newegg.com/Product/Product.aspx?Item=N82E16814500415 okay same as the pny
1 pny 1080 ti founders https://www.newegg.com/Product/Product.aspx?Item=N82E16814133648
1 aorus 1080 ti 3 fan https://www.newegg.com/Product/Product.aspx?Item=N82E16814125954 big card 3 slots wide

1 zotac 1080 mini does 140 watts and 500h
1 asus 1070 strix does 110 watts and 410h
1 msi 1070 gamer does 110 watts and 410h

I have a msi 1060 3gb gamer it was cheap it comes today https://www.newegg.com/Product/Product.aspx?Item=N82E16814137033 180 after rebate I had coupon so 170

Hi Phil,
Any specific reason you favor Aero over Aorus? any insight will be highly appreciated.

Regards,
BLife

@
BLife it is a true 2 slot card the aorus is a 3 slot card since most of my gear is slot based not riser based the aorus is harder to fit.

@ citronick that board looks pretty good my findings on the z270 gigabyte boards show me 5 cards are easy peasy never got around to testing six.

that board has spacing issues compare it to the z170

not so easy to do 4 galax katana 1070 with proper spacing

easy peasy four galax katana 1070's for the z170 and I have 5 or six on hand

I guess I might have a slight problem.

If you are undervolting, try to increase the voltage.
If you are overclocking, reduce it.

Try with almost stock settings, memory error should be in a way smaller order of magnitude (<1000/minute)

I was all amd I shifted to mostly nvidia

making 50 bucks a day so every 14 days I pay off 1 1080ti

so far 3 1080 ti"s are paid for.

Not sure how long the roll will last but just 28 more days means 5 1080 ti's will be paid for.

with BTC this high.... my group's mining ROI became even faster.... so I expanded to a 2nd GPU farm.
