I am getting an error when trying to run this miner.

Code: [Select]

[...]
spawning 2 worker threads
[b]error while opening the file gpuhash_0. Exiting...
[/b][...]

Are the files gpuhash_x in the same directory as the binary? I guess that the application cannot find the file.

Error during compilation of program for device 'Tahiti':

Internal error: Input OpenCL binary is not for the target!

How to fix this?

My card is 7950,and driver 13.1

Which OS? Catalyst 13.1 is most likely too old. Please try to update.

Thanks!
Hi,NaN
it's solved,I used v0.2 ,just 55xx. After i changed to v 0.2.2 ,the speed goes up to 75xx.
I  found the miner has potentiality to increase speed. i used  cg to mine ltc or doge,the power was nearly 900w. now ,i use this miner ,the power just 510w. So, how can incease the speed? overlock?

Try to play around with the settings because 75xx cpm seems too low. Overclocking is most likely possible because of the low power usage. Most important is GPU core frequency but be aware of the pitfalls when overclocking Tahiti GPUs.

three his 280x ,win7 13.1dirver.just get 57xx, it's too bad. use -t 0,0,1,1,2,2 .
 if add -a 1, the miner can not run. 
so, help me!

Which version do you use? I guess that you're using an old one. Use v0.1.4 or v0.2.2. If your monitor is attached to GPU 0, then I would use -t 0,1,1,2,2 and I would try -t 0,1,2 too. -a 1 should be fastest.

Hello NaN, I thought 0,1,2.... is the number of card ? because for 4 card i use 0,1,2,3.
What exactly is his number? eg for a single card I put t 0? it would change something to put 0,1,2 for a single card?

The numbers after -t are the DeviceIDs, which are shown during startup (DeviceID x). For each number in the list the miner starts one thread. Normally, the first GPU has DeviceID 0 so that -t 0 mines with one thread on the first card and -t 1 means that the miner uses one thread on the second card, etc. Thus, -t 2,2 means that the miner should launch two threads on the third GPU. It might increase your performance but at least the Windows driver of R9 290(X) seems to be broken and only the Linux driver functions with full speed. Just try whether  -t 0,1,1,2,2,3,3 or -t 0,1,2,3 give you better performance if you are using four GPUs.

So finally... no CUDA miner realized? 

I'm working on Nvidia support but I do not have a fully functional version yet.

Nice! So Linux is indeed faster than Windows for R9 290(X) cards.

I guess that you use a Catalyst driver that is too old. Please update the driver.

Maybe your Xorg.conf is screwed. Run aticonfig --initial --adapter=all as root and restart the computer.

Can I ask what you are using a version of the LINUX it?
I am using UBUNTU DESKTOP version
Only recognizes a GPU, only 2300C / M ，with 3800C/M so long way
Will there under LINUX how to modify the GPU CLOCK, MEM CLOCK, GPU fans

I tested on Gentoo. The command line tool to modify frequencies is aticonfig, which should work after enabling AMD Overdrive (see --help). How many GPUs do you have? For one GPU I would use -t 0,0 and for two -t 0,0,1,1 etc.
