it is easy, read the fucking manual

Thanks for nothing.

Hello
I will like to comment, that , even when --pec is a good tool to give an idea of the efficiency, it is not exact at all.

for instance, a 1080 at minimum target power limit uses 100W, but eats 124 watts at the wall (with a gold rated PSU at 40% load)
so if you want real numbers, use a AC wattmeter, like the Kill-a-watt gadget, or better, because that is the real power you are paying for.

cheers
indkt.

What mobo are you using?

I have kind of same problem with a MSI z170. I cannot use a 5th card on it. I know it is a recuring problem
with this board but I didnt have time to "mine" the solution yet.

I found the --pec numbers to be really close to my Kill-a-watt meter.

MY EVGA GTX 1060 in my gaming system seems to work pretty well for ZEC
Once the fan speed hits 50% or higher the noise becomes noticeable and annoying to me personally

What are the four different solvers?   So far I'm not seeing any difference in performance.

EDIT solver 3 seems pretty bad, 0,1,2 seems fine

I am using Asus Trooper B85. I added more 4G Ram, same shit. But kinda strange if I am putting one of the cards directly to mb without PCIe adapters - works great.

Thanks for the link. I am trying to emancipate myself from GUI overclocking :-)
But its been pretty confusing following that guide.
For example he states
Which is wrong, because he swapped the core/mem. It should state nvidia-smi -ac 4004, 1911.
But on my 1060 it also does nothing. Supposedly -ac command overclocking works only on Maxwell cards.
Also I have no idea why he uses GPUPowerMizerMode=1?
Does not do a thing on my side.
Anyone had better luck?
