Here are some wattmeter readings from my 5x 1080ti Rig.


All 1080tis are founder edition.

+250 core -502 mem
50% pow limit   700W   3885mh/s
55% pow limit   766W   4086mh/s

I run at 80%. Prefer less potential problems than making a couple more dollars. These cards will be running 24/7 for 2-3 years.

so :
60 to 65 = 70 watts  more and you get 158 mh extra
65 to 70 = 70 watts  more and you get 112 mh extra
70 to 75 = 70 watts  more and you get 120 mh extra
75 to 80 = 75 watts more and you  get 100 mh extra
80 to 85 = 70 watts more and you  get   93 mh extra


and I know that

85 to 90
90 to 95
95 to 100   are all worse then  80 to 85

ie the real cliff  of waste  is at 85 to 100

If it were colder I would run 80%

but I have no cooling in the garage  none nada zip  I have not been able to run with summer power cost since 2013  so I never bothered to make the garage have good cooling.

I am running in the 60%  area  for now and in the fall I will clock higher.

also remember  my summer power is 16.7 + say 2.3 for ac costs.  so 19 cents

my winter power is 12.7 - say 3 cents for free heat so  9.7 cents.

so OCT 1 my power bill is dropped 45- 50%  until June 1 next year.

me being in florida i had to do the same today my rate is always 13cents but the heat is killing me and the cards. ((wife isnt happy either))
i cut down on the mining by a lot running the 20 amd cards i have at 960core/1800mem
cut the power down by 4.3amps=1000watts losing about 20$ a day by doing this but it must be done room temp came down
it was sitting in the 95-100 range now its 80-85 range

when October comes its game on again!!

I noticed one of my gpus was going 54mhs and my second was doing 65mhs on lyra2.

So I was like I guess I have to tweak that one.. I seperated them on afterburn and I started tweaking.. no mater what I do.. 60%, 100% power.. overclock.. no oc.. the cars has no change.

The other card changes its mhs when I made adjustments.. I dont get it.. anyone know what I am doing wrong?

Gigabyte GTX1080ti Founders Edition VS EVGA GTX1080ti FE

Any opinions.  I already own 2x the EVGA ones and nothing good or bad about them.

You won't like this, but all chips are different. You may have FFF (fast silicon) and SSS (slow) silicon.  GPUz has a way to measure ASIC quality. https://youtu.be/I3DyiLAQ3Qk

Sounds like you have a good one, and a bad one.  Search these forums for silicon lottery

Run one card doing Lyra2. See what it does.

Run the other card . See what it does .

Some cards will run well with others some do  not.

Try just one card in two slots.

Try the other card in two slots.

Which means four runs.

Then try the two together. Then flip the two.

You may find the cards are not the issue the mobo may provide more reserves to one slot over the other.

Or you got a weak card.

Some say weak cards will do better on under clock.

So test at 50 % and 55%

One may really improve on a low clock

[EvilMonkey]

What is the reason when we mine skein and sometime zec that we drop the memory clock to -500?  Is this just to reduce stress on the card?   As I can't seem to see any performance or power difference.

if the hash rate  stays the same at -500 or 0  and the power use stay the same at -500 or 0

there should be no reason to not do either one they give the same result.

Since there is no gain by ram at 0  I set to -500 as an added safety factor as the card is working at the lower freq.

when I mine for months on end in my garage my entire slab of concrete gets warmed happens in the dead of winter when I am doing 20-25 amps ate 240 in the garage.

So longer high use takes a toll you will not see for first 60 to 100 days of mining.  thus I go -500

Thank you Phil. I will run some tests this weekend!

That is 4H/J from the wall. It is twice as efficient as my underclocked R9 390 system.

What coin would that be on ?
Did you try to run your rig on ethereum ?

I can't decide if to get 1080Ti or 1070 :/

Thank you

[Storx]

today has been a horrid day for me mining .......
But i did get this beauty in the mail finally after over 30 days of waiting.....

[vg54dett]

does it work as well as the 3x one ?

[EvilMonkey]

Looking at a new motherboard for setting up four cards.

Any other recommendations other than this.  list as many good ones as you can as is tricky to find stock in anything in New Zealand.

Gigabyte GA-Z270-HD3 $200 NZ 4 or 5 pcie?

Asus Prime Z270-AR  $250 NZ  7 x pcie?

Asus Prime H270-Plus  Or this? has one less large PCI-e slot but I have risers on the way.  only 180$ NZ\\

Any other recomendations.  Personally I like the look of the Gigabyte GA-Z270-HD3.

Next question. I cant get plat PSU here in NZ without paying around $200 premium until the next shipment comes here.

I have 3x 550w-600W PSU's.  Is there soem way I can use these to power my cards until a proper PSU gets her?  Like one PSU purely for the main system and one old as card to get a display and then 2x PSU for the remaining cards?  or is it not worth teh hassel?

I ordered one like that a few weeks ago.

post results soon when you get it going.

I saw angrybirds's build: 11 x 1070s, 7+2xM2 with 2 splitters = 11 GPUs working with 2 x PSUs

I decided to go density with the 1070s because its draws so little power, 6 x GPU at 660w@25MH ETH, even at 12 x GPU under 1300w is amazing.

Need some help with cable

so I have this vga cable that goes from [8 pin male] to [6+2pin male and 6 pin male] but my GPU needs two 8 pin power. I used one of these 8 pin splitter that comes with the GPU and connected on 6 pin male so I can connect two 8 pins with this one cable. Would it be safe to connect like this? I am leaving one end of splitter unconnected. Please take a look at the pic.

correction:

LOL

its not "angry bird" but "angry chicken"

its not 1070s but 580

nevertheless.... 11 x GPUs is a quite a feat
