NVIDIA GTX 1080 ti GPUs


#675

Hi there!

I’m testing a rig with Mac and GTX 1080 TI with ZCASH.
It’s running first day but I only have 550 Sols/s and as I saw here
people it’s running with 720 Sols/s with the same card.

What can I do for to push to the 720 Sols/s level?

How can I change the power, fans and other things directly
from command line in terminal?

Remember I’m on Mac!

Thanks !

Peace

Hmm - well in linux you use these commands to manipulate the power level

nvidia-smi -pl xxx (power level in watts) will set your power level
nvidia-smi -d -d POWER will query your current power level

Then there is a gui app to manipulate memory and gpu overclocking as well as fan speed.

Not sure if those exist in MacOS or not, but that’s what I used in Linux before I switched to Windows 10.
I use power level 80%, mem overclock +500, gpu overclock +150, fans at 70% always for approximately 750 sols/s

I just put a rig with 4x MSI GTX 1080Ti Corsair Hydro. I’m using linux ubuntu but I would like to have some directions of how to overclock them. I’ve done extensive reading and the rig is now completely functional but I would like to improve Sols/s. not reaching yet the ~700Sol/s
Do you use a particular script to do the overclocking? Which parameters should i be looking?
I really want to stay away from windows if i can.

I appreciate you insight Thanks!

Thanks MColeman but I need for MacOs.
Keep searching about this question…

dears ,

how i can know the power consumption of my GPU and the Sol/s ??

i am using the nice hash and i cans see power consumption and sol/s

results of my quick test of gigabyte AORUS X-treme watter cooled edition…
TDP - default
core +120
mem +500

Checkout nvidia-settings that should come with the nvidia drivers on Linux.

E.g:

nvidia-settings -a GPUGraphicsClockOffset[3]=40
nvidia-settings -a GPUMemoryTransferRateOffset[3]=40

Or a specific GPU:

nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=0
nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=0

Here is a small bash script that you can add and use as a shortcut:

# oclockall [optional_graphics] [optional_memory]
oclockall() {
    # set graphics
    if [ -n "$1" ]; then
        local GRAPHICSVAL="$1"
    else
        local GRAPHICSVAL="0"
    fi
    # set memory
    if [ -n "$2" ]; then
        local MEMORYVAL="$2"
    else
        local MEMORYVAL="0"
    fi
    nvidia-settings -a GPUGraphicsClockOffset[3]=$GRAPHICSVAL
    nvidia-settings -a GPUMemoryTransferRateOffset[3]=$MEMORYVAL
}

Hey,

Nobody else with MacOS ??

Thanks

Hey macperlita,
I am also running a 1080 TI on a mac.
Getting around 450 sols on my card as well. I’d love to be able to run nvidia-settings on mac but haven’t yet figured out if its possible.


#684

are the ppl with MACs not already rich? Kappa


#685

Raising the conversation. :grin:

Hey am new here, i have a questione can i connect gpu and the rizer, with one power connector with 8pin to 2x 6+2pin spliters? With this. https://images-na.ssl-images-amazon.com/images/I/61q3wVGIqKL.SY355.jpg


#687

you can but you run the risk of a short / meltdown / fire


#688

Sry i meant single gpu, and single rizer with one cable. I just have 8+6pin connectors on the gpu. And i read that its safe, is it? I mean am just adding one rizer, to pcie power cable.


#689

GREATLY confused… if it is a single GPU, why are you using a riser? Just connect it directly to the motherboard and forget the riser?

making sure I understand… Yes or No answer’s please

you have a gpu that needs a 8+6 pin to power?
8+8 pin?
8 pin ?
6 pin?

you want to take a 8pin power cable from the PSU and put an adapter on it to make it a 8+6 pin?

You have a riser that is also powered by a 6 pin?

IF you read that it’s safe, and are here asking is it safe, you must know in the back of your head that it isn’t…


#690

Are you using two splitters? Is your riser a 6-pin riser?

I think the splitters at 18awg (if you can trust them) will probably handle the current but the 8-pin from the PSU that you are splitting may not be rated for that - especially if it’s not an EVGA PSU. You’re better off powering the riser separately and using an 8+6 VGA for the gpu or two single 6+2 | 6+2 cables even.

As CitricAcid said, you will start a fire eventually if something isn’t rated properly. It might take a few months but it’s inevitable as the heat increases.


#691

Ohh ffs i made it coplicated, so i have a rig ready to mine, but still with one gpu, am going to add more bit later.
Back to topic i want to put the gpus and the rizers, with out any sata, molex cables. Instead use the same pcie power cables to power the rizers, to do that i need the pcie power cable spliters, so i can have 8+6pin connectors for the gpu, and one 6pin for the pcie rizer. So i can use the pcie power cable to power both, the gpu and rizer for it… Hope u understand now :DDD


#692

Yes, I understand better now.

No I would not do that. If the gpu was a single 8 pin or single 6 pin power need, then you could use the split cable that comes with the psu unit to power the gpu and riser.
But no, powering the riser with a splitter while also providing dual power to the GPU, that is way outside safe / best practice.


#693

Don’t even try it: it might even work (with garanteed lower performance) but it could cause permanent damage to MB, riser and/or GPU.


#694

I have three different cards, but they all get around 750 sol/s.

1080 TI FE 85% power 1950 GPU clock 5600 mem clock 62C
EVGA 1080 TI SC Black Edition 85% power 1950 GPU clock 5600 mem clock 47C
MSI 1080 TI Gaming X 85% power 1950 GPU 5600 mem clock 53C

I have 2 more EVGA 1080 TI SC coming in and a Zotac Amp Extreme Core so will be interesting to see if they all perform the same. Hopefully my second power supply shows up soon to power all of this.
