Topic: GTX1080ti's: Better Options? - page 2. (Read 13598 times)

if you run 4 1080ti's at 100& tdp it could be about 1060-1100 watts for whole system
if you run 4 1080ti's at 80% tdp  it could be about 850-900 watts for whole system
if you run 4 1080 ti's at 70% tdp it could be about 750 -800 watts

now some 1080ti's are jacked up to start the aorus is based on 300 watts so:
 4 at 100 % = say 1250-1300 for whole system
 4 at 80%   =  about 1010-1110 for whole system
 4 at 70%  = about    890-940  for whole system
 

I prefer to keep full system load around/under at most %80 of PSU capacity.

May rig 4 x1080Ti or 3x1080Ti and 1 GTX1080/1070?

Does a 1000 Platinum PSU such as Corsair HX1000i enough for such a setup?

It sounds like this setup will/can exceed 800Watts on the wall.

But if I optimize hash rate and power consumption, would it be OK?

8 gpu? ...

we build 5gpu max - aorus 1080ti extreme ...

even though it has the capacity for 6 - we have always come across problems with it ... though havent tries lately with the newest drivers ... as for 8gpu - you need a server borad that allows for memory allocation for the 8gpu in the bios from what we have researched ...

u have pix of 5 gpu aurus builds? definitely intersted! sounds awesome! I'm up to >40 1080Ti's now, have about 10 different cards but not a single aurus - i've been staying away because i'm scared of teh 3 slots it takes up -

I'm pretty much maxed out now but I am hoping to get another few locations to add a "few" more cards. maybe trying to expand too fast but IMO no such thing. go hard or go home

Which one for an 8 rig machine?

MSI GeForce GTX 1080 Ti FE DirectX 12 GTX 1080 Ti Founders Edition 11GB 352-Bit GDDR5X PCI Express 3.0 x16

Or

GIGABYTE GeForce GTX 1080 Ti DirectX 12 GV-N108TGAMING OC-11GD 11GB 352-Bit GDDR5X PCI

Latest fast ccminer's do utilize some shared memory techniques that put high stress on chipset when running rig with more than 4 gpus, I think. So if the mb bios or driver isn't tuned by vendor it leads to high CPU usage by windows "system" process that can lead to CPU heating. Is there a way to downvolt Ryzen?

I have similar problem with my asus z270-a but celeron g1900 is very lower power CPU especially with downvolt so this not bother me too much. My old socket am2+ rigs with amd 770 chipset are free from this problem thow

Yes, effective nvidia mining is rather tricky and can be time consuming.
You need to fine tune for every card and every algo.
I have txt file with my findings cause it cannot be remembered. Also I use not only Afterburner but Palit Thundermaster too cause AB cannot do -1000 memory downclock.
Moreover sometimes you need to manually edit freq/voltage curve to get stable effective mode.
And last but not least for Palits gtx1070 I just use SuperJetStream card bioses with my simple Jetstreams and GameRocks as SJS seems to be the best to achieve good mining results.

Not really sure how to say it more clear but I was mining using ccmineralexis78 skein only on my 1080ti and my Ryzen 1600x water cooled CPU is getting pretty hot.  Even though its not really being utilized.

what do you mean its a 1080ti? ...

What CPU's are people using and what temperatures are they getting upto?  My Ryzen 5 1600x with a mid range water cooling is peaking at 80 deg sometimes.  Generally it sits around 60 C though.

This is 1080ti running ccmineralexis78 skein only.

Just google nemosminer zpool, download the zip file.. dont touch the batch file and just create your own with a simple single line using the pool info on the pool of your choice. The reason i say this is because it seems to mine multi algo using the nemosminer, you have to run your GPU at OEM stock settings which are stupidly inefficient at mining really..., but each algo uses the GPU in a different way.. so oem settings are basically the only ones stable on it...but your using a ton more energy and generating way more heat to utilize that benefit.

Once you learn how to optimize your GPU by tuning the clocks and voltage levels, you can get near stock hashrates (Money making ability) at a fraction of the energy and heat.. but in my short experience once you get one algo fully optimized, as soon as you try another algo its like a 50/50 if it will freeze up your pc...

So your best bet is to stick to one algo, and mine it at the most optimized settings to increase your profit margin....then maybe later experiment with others and come up with optimization settings that work best with them.. so if a day comes you need to switch coins, you can just stop the miner, change the gpu settings, then start the new coin....

Example the current optimal settings for my skein settings will immediately freeze up on zcash or lyra coins, which is the other 2 common nvidia coins to mine, then my zcash settings will freeze on attempting to mine skein, but my lyra2 settings will actually mine skein.. they are different animals, so different settings are needed.. if it is possible to create a batch that auto switches settings before starting the miner that would be amazing accomplishment.
