thanks for your work on this tool. it is just what i was looking for as i've developed in the bitcoin arena. having total control in one app is great.

my experience did get off to a bad start though and was about to give up. the system i decided to try it on first would not work. i tried the compiled windows version, then tried to compile myself - oh that was fun.

i just could not get it to initialize the GPU so i moved it over to another system and bam worked right off. it turns out that my first attempt was on a pc that i was messing with the Intel OpenCL SDK earlier. i removed that SDK then CGMINER worked. this may not be news or unexpected but figured i would share in case someone else is in the same boat.

thanks again ckolivas, and all contributing members. now off to research centralized monitoring........

You're most welcome. Enjoy.

You sure your system didn't just run out of memory?

Lol... well... no

But it seemed cgminer was the only thing affected. Other things I checked on the server were still running (web server/sshd).
Its a dedicated rig, and pheonix never had any issues... I was just trying out cgminer and it lasted for about 4 hours before it died to the above message. Its 2 gig ram with small web server... after reboot, it appears cgminer is taking about 800 meg of virtual RAM and 400 Meg of physical RAM, is this normal for 6 gpu's?

3804 root 20 0 748m 356m 50m S 1.7 20.1 1:29.67 cgminer

Happened again after about 5 hours. I have a couple 2 gig RAM rigs running cgminer just fine with 3 gpu's each... its the rigs that have 6 gpus each that it occurs on after 5ish hours.. No sign of trouble right now... after 2 hours running, I have 738Meg free out of 2 Gigs. Full logs are located at:

http://pastebin.com/8MDeRMkD

Anyone have any ideas to help me troubleshoot whats happening?

Linux since 1997 RedHat 4

Um ... to state the obvious, unless it's from the AMD website - no one in their right mind should download it.

Edit: however that 898 number isn't new if I remember correctly you can get 898 from AMD?

I found a new version of OpenCL (AMD APP, Stream SDK, whatever they want to call it) in a leaked version of a beta driver. This driver supposedly gives Windows 8 support. Anyway, I don't give a bleep about the driver, just the OpenCL versions.

On Catalyst 12.3 with OpenCL version "2.6" my DLL versions are:
amdocl(64).dll 10.0.831.4
opencl.dll 1.2.0.0

From this leaked driver the DLL versions are:
amdocl(64).dll 10.0.898.1
opencl.dll 1.2.1.0

Uninstalled version "2.6", deleted the DLL's manually in System32 and SysWOW64 (necessary step going between versions!), then installed this new leaked version. Deleted my kernel bins in cgminer dir as usual, then launched...

Can't really see any change in performance. Hopefully this gives ckolivas and the kernel devs something to chew on and progress forward, though.

Driver link: http://jumbofiles.com/h2l4qczhjkb4
I will host just the 32 and 64bit versions of the OpenCL.msi myself for those who don't care about the whole driver: http://www.delta9IT.com/OpenCL32.rar http://www.delta9IT.com/OpenCL64.rar

The lowest memory clock AB will let you set is 685. You can lower the voltage in AB, but cgminer will run at 1.17V, no matter
what you set it using AB or other tools.

You still don't get it, do you? cgminer doesn't do anything unless you tell it to, AB doesn't do anything to the voltage, it runs at 1.17 and other tools tell you what it's set at while cgminer tells you what it's actually at. A new version of AB might change it in the future, and then cgminer will show that value, but cgminer still won't be doing anything to it.

Is it possible to lower the memory clocks on the 7970. Mine keep going up every time I try and reset them lower.

7970 in linux is stuck at engine -150 -- cannot go lower.

cgminer just stopped for me sometime last night... This was the start of a long set of logs at this time:

Code:


Mar 16 04:10:40 skynet kernel: [13242.684124] cgminer invoked oom-killer: gfp_mask=0x280da, order=0, oom_adj=0

I can post all the rest if needed, but figured I would start with the above.

At 1175/1025 they can hit 700.

That puts a rig of 4 around 1170W and puts out a ton of heat...

Well - 4 on one MB, running linux with a 1250 watt PSU at 1050/900 (7970 mem can only be Core - 150) and Intensity of 11 will get you 2.5 Gh/s.

Use this driver

Code:

amd-driver-installer-8.921-x86.x86_64.run

Must use the 2.6 SDK

Then to avoid the CPU bug make sure to run

Code:

export GPU_USE_SYNC_OBJECTS=1

2.3.1 version of CGminer is damn stable!

Aren't they supposed to get 700 per card.

Just received 5 new shiney 7970's and was wondering whats the best setup on cgminer for these. I keep seeing diablominer as the best but I just love cgminer. Any help is appreciated.

Nobody ever said cgminer WILL change the voltage. I said cgminer WON'T change voltage (or any other card parameter) unless you tell it to. Sorry you were confused.

To anyone else wanting to avoid frustration some tips:
1) cgminer doesn't change anything (core clock, mem clock, voltage) unless you specify a value.
2) cgminer displays what the card is running at. some other utilities show what the card is SET at. If cgminer conflicts w/ other utilities cgminer is likely right.
3) When setting values cgminer uses AMD ADL library. It ASKS the card to change the value. The card is free to ignore it. Some cards may ignore all requests, some may ignore just ones they consider "invalid". Some cards may reset to stock after invalid value, some cards may keep last valid setting.
4) Exactly what happens depends on the exact card, the hardware, the vendor, and even the BIOS version (same exact card from same vendor with different BIOS can behave differently)
5) Don't use multiple utilities (TRIXX, atitweak, cgminer, AB, Catalyst) to change values at the same time. If changing values with another utility don't specify a core, mem, or voltage parameter (as applicable) in cgminer.
6) P4Man encountered a situation where a VRM was damaged by using two utilities which read voltage directly from the hardware at the same time. Be careful with these non-compliant utilities which read and write directly to the card hardware.

D&T,

I think af and I have been confused about the lack of cgminer to change voltage (underclock) on 7970s. I skipped the 6xxx series and all my 5xxx series are able to be changed via cgminer. Jake's post a few back describes the situation well = fscking AMD...

For the last time af.

Nobody said cgminer MUST work.

cgminer doesn't change the voltage UNLESS YOU TELL IT TO. Period.

If you don't specify gpu-vddc and cgminer REPORTS 1.17V that doesn't mean cgminer CHANGED IT TO 1.17V. It means CGMINER QUERIED the card and the card indicated it is running at 1.17V.

Very important that you read and comprehend what is being said instead of making assumptions, then getting confused and then blaming your problems on other people.

For some reason, my AVG tells me that CGMiner is a virus, and I can't use it..
It only happend today, and I've been mining with it for atleast a couple of weeks..
