Topic: EWBF's CUDA Zcash miner - page 176. (Read 2164327 times)

Hi friends diggers, I want to ask maybe someone encountered such equipment ... I have 4 power supplies here are those with 2 servers IBM 570 (5628 IBM 1600W AC Power Supply 44V3086) but the problem is that they do not have wires! I would like to solder the standard wires to connect to the motherboard and video cards, who can help to be ready to reward such power supplies, please help me to unzip 2 pieces and 2 pieces I will give to you. Maybe someone here lives with ukraine from Kiev. There are many more similar units but slightly lower power from 1200 to 1400 watts. Thanks in advance.

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?

Hello EWBF,

Any new updates coming or is this pretty much the final version?

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.

Anybody have a figure for 780Ti or is this miner only for Pascal?

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

thesmokingman, that guide worked very well actually, I was able to use a number of things there to boot strap my configuration - Thank you for the heads up on where to find this info, exactly what I needed to make a lot of progress.

Currently, I've got:
Fedora 24
cuda_8.0.61_375.26
NVIDIA-Linux-x86_64-375.39

Running at 135W
/w Clock + 200 @ 1950Mhz
/w Mem + 1500 @ 4551Mhz
435 Sol/s

Much better performance than I had earlier, but compared with my windows config still under-performing by ~4%
On windows @ 135W
/w Clock + 200 @ 1850Mhz
/w Mem + 700 @ 4498Mhz

455 Sol/s


I can't account for all the differing values of mem clock offsets, nor am I sure which measurements I should trust of the absolute clocks. No idea why in windows I apply +700, but linux takes +1500 to raise it an equiv actual 700Mhz. Very odd stuff.

Either way it seems if taken at face value - I'm running slower on windows(1850 v 1950, and 4500 v 4550) and getting 4% more solutions/sec.

EWBF - is there some optimization that you might be able to recommend for linux? What optimizations should I look at further to close the gap all the way - and my hope was to get better performance in linux.

P.S. Very happy I got this working in Fedora 24 - I got 25 working, but it is... messy due to having to hack away at the nvidia installers.

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

True!, it is!.

interesting that the results of the 1080Ti is better at 135W, similar to the 1080 which is at 110W, not at the lowest setting but a little higher than minimum.

thanks cryptohminer for the data.

Yes , but --pec is very good to compare cards.

Maybe someone can paste --pec @gtx1080ti ?

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.

Seems better with the flypool server. But when I get disconnected the mining doesn't seem to restart until I press enter:

"Error: Lost Connection with the server. Attempt reconnect..."

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.

Could the 1080ti holder be able to paste the results @stock and undervolt  with --pec (speed / power usage /efficency )

sry for my eng

Thanks for nothing.

You have to play around with the xorg.conf file and trick Linux into thinking their are monitors attached to each card. Not sure if dummy plugs will work, but I have overclocking working. Highest I've hit with my Gigabyte Gaminig 1 rig is 430-460 with just playing with mem. Cards crap out at anything over +50 clock speed.

Here's a guide I used to get iverclocking working in Linux. Hope it helps:
