Topic: OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.0 - page 396. (Read 5806015 times)

I'm getting about 20-25% cpu usage on gentoo (htop shows the main process accounts for all of this, but there are about 10 other cgminer entries) with an amd 8350 and two 7950s. I have another box with one 5770 and one 7950 and it showed similar behavior (about 13% cpu usage). If I disable the 7950 then the usage goes down to 3-4%. I am using -I 5,8 -w 256 -v 1 and I have tried all of the kernels. I have also tried cgminer 2.10.4 and 2.11.2. I have another couple boxes with 5830s and 5770s that have less than 2% cpu usage. Any thoughts as to why the 7950 boxes have higher cpu usage?

Hi, after some time I am testing mining again - similar setup, new GPU.
I am not able to lower gpu mem clock, it always jumps to 1200 when I enter a different value (and it hungs soon).
Another guy mentioned, he achieves around 300Mh/s with 1050 MHz gpu eng and 600 gpu mem clk with GUIminer(windows)-and his temps are around 55 C(two fans).
Would anybody have an idea what can I do to improve hash speed ?

Linux Fedora Core 16 x64, MSI 7850 (only one fan
cgminer from git,ADL,amd app sdk 2.8

when I run ./cgminer --benchmark
I get speed 228.2 Mh/s (when setting engine clk to 1120 MHz)

Thanks a lot !

Uhm. With LG 2 and TC 22392 I get:


Ok, the above error seems going away using:
(I never ever needed this thing before).

However, I get:

Where is the "safe" setting? What is ADL?

Try set "safe" settings and disable ADL. I have similar troubles when ADL is enabled and I switch user or enable screen saver...

Ok. I still cannot get CGminer working how I'd like it to.
I have been through 7 OS installs in the past two weeks, 20 different ATi driver installs, 10 CGMiner installs. + much much more.


Initially I couldn't get windows to recognize all the GPU's at once, so I went to ubuntu, and back to windows and then to another version of windows.............................. Well one day it just worked, I did nothing special I can rememeber it just all of a sudden worked..............................

So the day it worked I threw all my GPU's up on CGMiner (10.5; CCC 13.1), and used it for another week or so. Everything was *seemingly* fine, <75C for each GPU. Ran 1Ghash even with x4 5830's. No OC, no nothing, just stock.

Well, with this I kept getting BSOD and AMD driver crashes. To fix this I flashed my BIOS, reinstalled windows, install AMD driver 12.10 and CGMiner 10.5.
For a while I couldn't (AGAIN) get the GPUs to all be recognized, and as it happened the first time, it just worked one night......

Now that I had it working......
I tested each GPU individually by running it on CG for 10mins or so. All the cards ran about 75C and 3200RPM. Which is what they ran at before this BIOS flash and new CCC and CG.

NOW, when I run two or more, the cards get HOT. 90C in seconds, but they are maintainable/stable. Prior to this, the temps were low but they would crash the system, now the temps are high but the system wont crash for stupid reasons as before(BIOS, Drivers, and OS not speaking correctly).

I have tried setting GPU fan to 100% and Auto, lowering the clocks, dynamic intensity, more fans, different TIM (reset the TIM on each card Multiple times), carressing the GPUs before I go to sleep. Nothing seems to work to get them back to their coolness prior to the new software...



I am not even sure what I am trying to do anymore. So many fucking software problems my head is spinning. And no one can give me a good answer. This computer is making me look like a preschooler.

7970 @ 1135/1890, LG 2, TC 22392:
No, the memory speed is not a typo. Ignore the accept/reject ratio; I was trying solo.

EDIT: The code is now in git, and here's a windows build with the changes:
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

And how much faster is it? :-p

Latest cgminer shows strange behaviour (yes, the screenshot says 2.10.5 but I also tried the latest 2.11.2):
http://666kb.com/i/ccdeq3e6alsbklzis.jpg

Going back to 2.9.7 completely fixed the problem of 100% CPU spikes on two different machines.

For all you crazy scrypt/LTC mining fanatics, I have finally found the reason you cannot set very high thread concurrencies or intensities on 79x0 cards. It shall be fixed in the next version. I'm able to run my 7970s at TCs of 22392 now.

GPU mining usually requires X (Unity is just an X display manager - xubuntu uses xfce)
Headless is fine, but X still needs to be running for cgminer to get at the GPU properly
As long as the machine boots into X that's what you need.

lol - ASICs just mean that GPU scrypt miners may just start out with LTC (or even Novacoin?).

Despite grabbing the 12.10 image and saying yes to d/load updates during the installation I still seem to be outstanding some 256 Mb of updates for Ubuntu so I will let those download/install and come back to this later in the day

Kano - If the Unity interface is running X must be running? Perhaps my Solaris background is leading me astray there tho? - Linux experience to date is limited. Ultimately I intend running headless - I don't want or need anything more than ssh to connect.

I was hoping by now I could have said something like "GPU mining is deprecated, only ASIC code is supported from here on"... but it seems that was a pipedream  , and scrypt is coming back to haunt me with a vengeance  I haven't seen so many new questions about GPU mining in over a year...

X is running?
export DISPLAY=:0
or to test:
export DISPLAY=:0 ; xlsfonts works?

Thanks for that - I had run the --initial command and thats whats stopped me mining completely before and ended up reinstalling Ubuntu again - having run that now I get...

I have another version of OpenCL:
is this ok or should I upgrade?
TIA

ck, add this command to readme... I see this every 5th page or so ;]

OK having some difficulties with a 2nd gfx card, reinstalled a couple of time and starting to tear my hair out a bit now so forgive the nooby questions but learning a lot here.

Have installed Ubuntu 12.10, the latest catalyst drivers, rebooted, installed the AMD SDK rebooted again and then installed the pre-built cgminer 2.11.2 as that was built on the same platform. Also run an aticonfig install.

I have an AMD Radeon 7950 which is working fine and hooked up to my TV currently via VGA port. Also installed is a 5770 that I got cheap so decided that would be a great bump.

Problem is i cannot mine on the 5770.

if I do an aticonfig --list-adapters both cards can be seen...

  1. 02:00.0 ATI Radeon HD 5700 Series

* - Default adapter


I have hooked up the 5770 to HDMI to make sure the card came up but I am not getting any output there either so I am thinking either the card is partly cactus or I have just not it right in Ubuntu?

Any pointers appreciated.

This is true, however I still get "no rule to make target". Am I missing a flag?

Herp Derp...was missing libusb-1.0 (was stated in config logs)
