Re: HOW TO SET UP OVERCLOCKING AND FAN CONTROL ON UBUNTU 16.04 FOR NVIDIA CARDS

If using monitor attached to intel graphics of ssh try this command. This worked for me with Xubuntu 18.04 and nvidia 390 drivers.

sudo nvidia-xconfig -a --cool-bits=31 --allow-empty-initial-configuration
sudo systemctl restart lightdm.service
sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a 'GPUFanControlState=1' -a 'GPUTargetFanSpeed=100'

This changes fan to 100% but over clock works the same way.

I found the answer here.

v3.6.11 is on github but no details on the changelog.

Thank you to the developer!

I have never used docker before. How difficult is it to compile cpuminer-opt and run it in a container?

With Ubuntu 16.04 container:

Code:

I am still curious about AVX2 performance on Ryzen. I have read that their implementation isn't native but I haven't
seen any performance comparisons. If anyone has a Ryzen I would be interested in a performance comparison of
AVX vs AVX2 on algos that have AVX2 optimizations.

If you can list the algos you would like tested I can try it out on both Ryzen R7 1700X and R5 1600 CPUs. Possibly on Threadripper too towards the end of summer if I talk myself into getting one. Wink

Lyra2v2, Lyra2z and Deep have the most AVX2 and should see the biggest improvement. All the X algos, qubit, timetravel
and a few others also have varying amounts of AVX2 code.

Preliminary results:

Ryzen 1700X @ stock settings with 8 threads set in the batch file.

Lyra2v2 = 1001 Kh/s on avx2
   = 1016 Kh/s on avx
Timetravel = 799 Kh/s on avx2
   = 843 Kh/s on avx
X11 = 686 Kh/s on avx2
   = 711 Kh/s on avx
X17 = 294 Kh/s on avx2
   = 294 Kh/s on avx

X17 was the same for both options, but I was surprised to see avx beating avx2 for the other algorithms tested. My understanding was that it would likely be the other way around....

Please test the HW SHA for Ryzen.

What is the lscpu or cat /proc/cpuinfo output for the coffee lake cpu?

Are SHA extensions supported like as in the apollo lake CPU?

Thank you for your help.

Which package needs to version 1.1?
libssl-dev or libcurl4-openssl-dev?

I have Ubuntu 16.04

How do I compile without SHA?

I thought the hash rate was pretty good for a 10w CPU.

I just enjoy playing, not any profit really.

libssl-dev 1.1 is needed but Ubuntu 16.04 has 1.0.2. None of the major distributions seem to have it yet.

How did you compile, did you change any options or just use the build script?
The option to add sha is "-msha" but the default compile probably includes it.
You might have to do something like ~~"-maes -mavx"~~ "-maes -msse4.2" instead
of the default "-march=native" to compile without sha.

Edit: correction, Goldmont doesn't have AVX.

That's a pretty big difference, big enough to convince me. Maybe SHA was back ported to some later 1.0 releases.
That's great if Ubuntu 16.04 etc have full support already.

Good work.

I used debian 9 with openssl 1.1 and got the same speed as ubuntu with the libssl-dev 1.0.2g-1ubuntu4.6 installed.

That's very interesting. SHA is not mentioned here...

https://ark.intel.com/products/95594/Intel-Celeron-Processor-J3455-2M-Cache-up-to-2_3-GHz

But here it is...

https://en.wikipedia.org/wiki/Goldmont

OK so you have a Goldmont and it is the only Intel CPU to support SHA at this time.

It looks like all the boxes are checked, CPU, compiler, build and algo. The only question seems to be
the version of openssl. Cpuminer doesn't check the version but it needs to be 1.1 to have HW SHA support.
The only way to be sure is to compare the hash rate with a non-SHA compile.

Edit: strictly speaking, when cpuminer says it's mining with SHA it means it is using the openssl version
instead of its own SW version, but it's no guarantee that openssl is using the HW SHA instructions.

Looking for Ryzen owners to test SHA acceleration.

Ryzen CPUs have HW accelerated SHA, something Intel's mainstream CPUs won't have until Cannonlake.

Requirements:
  Ryzen CPU
  Linux
  Compiler version with support for sha
  Openssl development package with support for sha
  Cpuminer-opt source code with support for sha

I can provide the last one. GCC is supposed to have support for -msha starting in v 5, and Openssl added support in 2014
so both should be available in Ubuntu 16.04.

The following algos use sha256 and should benefit from HW acceleration: sha256t, lbry, skein, myr-groestl, m7m.

Intel J3455 ASRock J3455M with 1866 memory dual channel
--benchmark results

lbry         Total: 5287.13 kH, 1341.57 kH/s, 43C
sha256t      Total: 4643.44 kH, 6343.56 kH/s, 42C
skein         Total: 15.05 MH, 3223.62 kH/s, 45C
myr-groestl   Total: 7336.60 kH, 1480.04 kH/s, 44C
m7m         Total: 254.99 kH, 38.28 kH/s, 45C

Thanks but that CPU doesn't have HW SHA. This information is displayed
when the program starts.

Compiling is still the biggest challenge to using SHA. Few Linux distros include openssl 1.1 which added SHA support.

It looks like HW SHA to me? This is only a 10w CPU.

Install Ubuntu 16.10

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-370 nvidia-cuda-toolkit
sudo nvidia-xconfig -a --cool-bits=31 --allow-empty-initial-configuration

Well, you can do that, but when I tested it, some mining software lost a lot of after 4-7 hours of mining and hashed at 60% less.

I mostly run folding, results may vary I guess.

I haven't had enough time testing it , but wit the current ccminer v7m7 , the results with the XCN are not so well. Its about 10MH/s but it should be twice better - my opinion...

twice would be a lot... knowing that a 780ti does only 14mh/s

You can get already a little more by overclocking the memclock of the p2-state to its maximum with nvidia inspector (which is 3500mhz and correspond to the nominal memclock value).

I will publish soon an update to use better launch parameter for the 980 (because for the moment, it just picks those of the 750ti), my 980s are doing around 12.5MH at the moment...

My Gigabyte 970s say P2 as well.

I may have stumbled on a common thing though, these are all 3rd party tools. Nvidia inspector, Precision X, and afterburner all said my cards were running at 73% utilization, but When I go into Geforce experience and click on led visualizer, and then GPU properties, it shows them at 98%, 78C, and 3000+rpm fans. I have them with a 750ti all crammed in my case, otherwise I'd run the fan curve differently.

(I don't use geforce experience and don't know where other system monitoring is if it's in there or another nvidia tool)

nvidia-smi in linux reports P2 on my MSI 970

Busy, busy ^^" I'm working on making it possible to add custom algos and coins, so you won't have to rely on me to add algos or on coinwarz/whattomine/etc.. to add coins, alongside loads of other improvements, ofc.

Would it be possible to add curecoin? I can find calculators for mining, but not for folding.

Edit: I found one, https://cointweak.com/calculator/coin/cure/FAH

take Makefile.am from tsiv's branch, then you're good.

Where can I find this file? Please provide a link.

I found https://github.com/tsiv/ccminer just trying to compile this fork now.

I posted two versions, one for compute 3.0, and one for the 750ti's

The one you want is the one with the older date in the file name

In fact, its this one

2. what linux do you guys suggest for a 5 GPU rig? I'd like to use debian if possible. Is everything available for that distro?

I use debian sid and it works ok. Drivers and cuda in repository work with GTX 750 Ti. I haven't tried 5 gpus.

I ordered a EVGA gtx 750 Ti and I want to put it in a rig with a gtx 660. I am using debian with nvidia 319.82 driver.

2 questions:

Will the card work with the 319.82 driver?

Will I launch cudaminer with the same command line options and it will use both cards? I am using autotune with vertcoin.
