So I assume pretty much everyone here uses MSI afterburner for tweaking and monitoring (with GPUZ thrown in on the side). Is there a skin that makes the program more usable? I've been using it for years and it's always a PITA scrolling throw the graphs on the right and changing between cards for tweaking. Not to mention the graphs get messed up and aren't always organized by card.

My rig was configured over ssh completely headless.

1.5.66 LAST
ASUS GTX750Ti 1421/2850 = 7Mh QUARK, 3.3Mh X11, 5Mh Lyra2v2

PS. And how about benchmark with all algo? Example: 5min QUARK, 5min X11, 5min Lyra and etc. And small table with result. Or maybe 2min... After some time your have bench in all algo for compare.

Testing out cuda 7.5 now. Managed to increase the hashrate in the lyra2v2 +50khash on the 750ti with some modification of the code..

But the other algos are down..

quark is bleeding. 5,5 MHASH vs 6.MHASH on the 750ti.

edit:

retuning x11 now. Managed 2860 in cuda7.5(x86)  vs (2940 in 6.5)  getting closer... Low profile 750ti 38w tdp

If it's about precision, can I recommend the benchmark ignoring hashrate results in the first few minutes or so? Giving time for the cards to ramp up (temps/fan speed).

Thanks, I was going to ask for something like this or do it myself.
This + fixed fan speed will help a lot.

I will implement a benchmark mode wich will exit after a given interval.

--benchmark 1000

 (run for 1000 seconds and display the average rate in the end.)

This way I can compare small changes in the hashing algorithm with a higher precition.

Also useful for performance regression tests.

Cuda 7.5 seems to run a little bit slower than cuda 7.0.

It will convert your titanx to a 980ti card.  Performance wise..

tried:

sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration

+ the cool_cpu2.sh script and it works! :-)

(latest drivers)

i've stayed with older nvidia drivers because my system is stable.  can anyone that is running the newest drivers under linux tell me if nvidia-settings works over SSH?  that was one big failure of the older drivers. all configuration of setup and overclocking had to be done locally with a monitor attached, and then the rig could be deployed headless.

THANK YOU! --

For correcting me.  I should have read the manual first.         --scryptr

-a is equivalent to --enable-all-gpus, which configures an X screen on every GPU in the system.

I've tested the sctipt on Ubuntu 14.04 with two 750 Ti.

SOLO MINING VERTCOIN--

The question was asked a few pages back about solo mining VertCoin.  I was able to set-up and mine VTC with CCminer release dot 66 on Windows.  Here is what I learned:

     1) The VertCoin wallet looks for a file called "vertcoin.conf" BY DEFAULT on startup.
     2) The VertCoin configuration file "vertcoin.conf" only needs to be minimal.
     3) The folder to place "vertcoin.conf" is in ...appdata/roaming/vertcoin in windows, under the login user files.

Here is my vertcoin.conf file:
=======CUT LINE=======
server=1

daemon=1

rpcuser=username

rpcpassword=x

rpcallowip=127.0.0.1
=======CUT LINE=======

Notice that no ports are mentioned here!

Here is my CCminer command line:

ccminer.exe -c solo-vtc.conf

I use a configuration file to launch.  Here is my configuration file, solo-vtc.conf:

========CUT LINE=========
{
   "url" : "127.0.0.1:5888",
   "user" : "username",
   "pass" : "x",
   "algo" : "lyra2v2",
   "devices" : "0",
   "intensity" : "19",
   "cpu-priority" : 5,
   "cpu-mining" : "true",
      
   "api-bind" : "0",
   "statsavg" : 20,
   "quiet" : false,
   "debug" : false,
   "protocol" : false
}
========CUT LINE=========

Leave the cut lines out, but don't forget the curly brackets.  THERE IS A PORT HERE!  It is the default RPCport (5888) for VertCoin.  You may want to lower the cpu-priority or intensity for your hardware.

It works for me.       --scryptr

EDIT:  MINE ON A LAN--

For those of you that have a "work" or "home" computer with a wallet, and one or more mining rigs, the setup is a little different.  In "vertcoin.conf", set the "rpcallowip" line to "rpcallowip=192.168.1.*", or similar if your local net uses a different configuration.  The asterisk is a "wildcard" that will allow any rig on the local net to link to the wallet on the home computer.  On the mining rig(s), for the url use the physical, numerical address of the home computer, i.e. "192.168.1.111:5888".  If you are using a command line only, use "ccminer -a lyra2v2 -o http://192.168.1.111:5888 -u username -p x".  You can get the lan address of the home computer from your router; I set this example to "111".

There may be a looong pause on miner lanch, but if you don't see red, just wait.  Hash results for your cards should appear within 90 seconds.  Of course, you can tweak the command line with performance flags.  If you also mine with a card on the home computer, make sure you use the lan address for the wallet, just as in the previous paragraph, not "localhost" or "127.0.0.1".  There is still a long pause before hash results.


Local GTX 960 card on Win 7 work computer and Linux 750ti mining rig on LAN


The cards will hash until an "accept" is received.  Then your wallet will be 50 VTC fatter.       --scryptr

Noticed something interesting on my 6 card EVGA 750ti SC miner.  When I use -C I get about 39250 Kh/s (No OC).   If I do not use it I get about 39000-39190 Kh/s.  Now if I mine Axiom with the nicehash cpu launch miner with just one thread running (No -C 30% load on CPU).  https://github.com/nicehash/cpuminer-multi/releases  I get 39235-39240 Kh/s  I am running a Intel i3 4330 (dual Core 4 thread CPU)

This is with 1.5.66 commit. 1056  Cuda 6.5 Windows 8.1 Pro Driver 355.60

my command line is ccminer.exe -o stratum+tcp://stratum.nicehash.com:3345 -a quark -q -u bitcoinaddress.2 -p d=0.04 --cpu-priority 3

 

awesome, thanks for the leads. Hrm, forgot the 950 needs a 6 pin power line...

COMPUTE 1.0 -

CCminer works with compute 2.0 and up, depending on the coder who wrote it.  A 550ti is "Compute 2.1".  SP_ codes for compute 5.0 (Maxwell, 750ti) and later. A 9800 is Compute 1.0.  So, no luck, for any practical mining with the 9XXX series.  You could play Tomb Raider with ease, though.         --scryptr

Good old cudaminer I assume that ccminer don't work with old cards like that?

I have a 9800 GTX+ card, the top of the line for the series.  It mined script at 14kh/s using CudaMiner.  My 550ti got 90kh/s, and the 520 that came in the system got 21kh/s.        --scryptr

Question from a friend: He have a couple of Nvidia GT 9600. Can he mine anything with them?

LINUX OVERCLOCKING--

You will need to do some web research.  It depends on your Linux drivers.  HashBrown has written and posted on this topic in the Kopiemtu blog thread, his work is for slightly older drivers.  Only a few posts back in this thread, I mentioned how to use nvidia-xconfig to set CoolBits.  This is possible with the very latest nVidia drivers.

Frankly, I would write a tutorial but I haven't updated my drivers and actually done it myself.  My system is stable, my 970 cards are getting 16.5-17Mh/s on Quark as is.  I have been reading all over the web about Linux overclocking, though.  Useful search terms include CoolBits, nvidia-smi,  nvidia-xconfig.  The very latest nVidia drivers simplify things; some of the posts that are 2-3 years old are outdated and involve more complicated configuration editing.

Apparently, the "nvidia-xconfig" command will write out a config for your system, but only with the latest drivers.       --scryptr
