When mining Vertcoins I have found it is very important to use the right Catalyst drivers, so please post OS and driver version with your settings.

I have been struggling with my hashrates, but just as an example I have 5x R9 290 (in two different systems) under Windows 7 ultimate 64 bit.

With stock speeds, intensity 17, tc 24550, w 256
Catalyst 14.1 gives around 250 khash/s
Catalyst 13.12 gives ~300 khash/s
Catalyst 13.11 beta 9.5 gives ~400 khash/s

So, if you feel you are stuck and have tried everything - don't forget to try different drivers as well.




Thanks for you suggestion, however I find quite hard to find the 13.11 beta 9.5 drivers for linux in the net, they disappeared after realising the new beta.

EDIT: I tried 13.11 beta 9.55 nothing changed, apart from not starting with -g 2 at all.

I was trying 8191 and 8193 - nothing has changed.
I even switched AMD drivers to 13.12 - still nothing. I also upgaded the vertminer to the 0.5.4pre.
I've got enough for today, I don't sleep because of the VTC ; )

I'm leaving it with -I 13 - g 1 --threads-concurrency 8192 --> at least I will have about 295 kH/s.

: (

btw pkjames you should probably erase your personal data from this screenshot ; )

All right, I finally managed to discover what was the problem. (gigabyte r9 280x)

After disabling

Code:
export GPU_MAX_ALLOC_PERCENT=100

I am able to set - g 2 parameter. However now when intensity 13 is set, I'm getting HW errors. The highest usable intensity is 12, but still can't squeeze more then about 300 kH/s : |

Code:
export GPU_MAX_ALLOC_PERCENT=200

doesn't work.

(Ubuntu 13.10, vertminer 0.5.3, AMD linux beta driver 14.1, AMD-SDK 2.9)

Any ideas what might be wrong? With - g 2 set, I've got nice 350-370 kH/s but definitely too much HW errors.

Have you any experience with 13.12 AMD drivers? Are they better regarding mining vertcoin than the beta ones?

Has anyone compiled a Linux distro for Vertcoin mining? I'm currently on BAMT but I'd love to get into mining VTC... and I'm a total Linux noob :-/

You don't need to compile any linux distro yourself, you can use for example the last Ubuntu, personally I used the mini.iso : )

I've got similar problem with Gigabyte r9 280x.

I can't in any way get over 300 kH/s. Well it would be nice if it reached something about 350 kH/s ; )

My current settings:

Code:
-I 13 --thread-concurrency 8192 -g 1

Any ideas?

And also one thing is bothering me, why I can't set 2 gpu threads  (-g 2)?
It's impossible in any configuration : (

I think the gpu threads is probably your problem, but I don't know why you can't set -g 2.
I am running 4 Gigabyte R9 280X cards in one of my rigs on Xubuntu 13.10 and vertminer 0.5.3, gpu BIOS undervolt @ 1.094V. Still tinkering but these settings are what I'm using for now:

Code:
--scrypt-vert -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-engine=1025 --gpu-memclock=1500 --gpu-powertune=20





I tried your settings, thinking maybe the gpu-powertune=20 will help, but I'm still getting this error, if gpu-threads parameter is set to 2:

Code:
Error -4: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)

However in the meantime I reached stable 325 kH/s with these settings:

Code:
-I 19 -w 256 --thread-concurrency 8192 -g 1
