14.1 drivers

Sorry for late response. Does it still work with the 13.12 drivers? If so i'm not going to give support for a beta driver, as 13.12 is still the latest stable.

Berti11 commented 10 years ago

I actually reverted to 13.11_BetaV9.2 drivers due to instability that comes with crossfire. Which also don't seem to work outputting the same errors.

Alright, if it's in both those betas i'll have a look at it. If it won't reproduce for me i'll need you to run a debug version to gather information.

Actually. First. Given the errors invalid memory size, it seems that your system is not allowing mty_cl to allocate enough memory on the gpu. My code does use a fair amount of memory, but it should not be anywhere near too much for a 290x.

Try to open a command prompt, navigate to mty_cl, and run setx GPU_MAX_ALLOC_PERCENT 100 mty_cl_amd.exe

I needed to do this to be able to run cgminer at full potency, which i did before ever trying mty_cl on the card, so i might have inadvertently hidden this issue from myself.

Trying the latest beta the problem did not occur for me. I've cut down some memory usage, though, by reducing the batch size. I'd like you to run this version and tell me what the result is. http://www.mediafire.com/download/7l5t1a1s5ii38ar/mty_cl_amd.exe

I would still like you to try setx GPU_MAX_ALLOC_PERCENT 100 and tell me if that fixes it. The memory requirement of the version that fails should only be about 350mb for a 290x, which would fit on the device ten times over.

Im sorry I was away from the keyboard for a while, the executable you sent in the last post fixed it, and so did the setx command.

madsbuvi commented 10 years ago

Alright, i'm gonna add a note for windows users to use setx for now, and i'll look at ways to do it from the program for later.
