Troubleshooting

Please be sure to update your video card drivers before you post an error!
If you're 100% certain your drivers are up to date and are still encountering crashes or compile errors please post in this thread.

Download the latest build, run it, and post a reply with the following information:

1) When you run the miner, what's the first few lines that pop up on screen?  It should look something like this:

Code:
Available devices:
Platform 00: Intel(R) OpenCL
  Device 00: Intel(R) HD Graphics 4000
Platform 01: AMD Accelerated Parallel Processing
  Device 01:        Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
Adjusting num threads to match device list: 1
Initializing workers...
Initing device 0...
Initializing GPU 1

======================================================================
Device information for:        Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
CL_DEVICE_GLOBAL_MEM_SIZE:            8258832 kb
CL_DEVICE_GLOBAL_MEM_CACHE_SIZE:           32 kb
CL_DEVICE_LOCAL_MEM_SIZE:                  32 kb
CL_DEVICE_LOCAL_MEM_TYPE:           CL_GLOBAL
CL_DEVICE_MAX_WORK_GROUP_SIZE:           1024
CL_DEVICE_ENDIAN_LITTLE:                    1
CL_DEVICE_ADDRESS_BITS:                    64
CL_DEVICE_OPENCL_C_VERSION:         OpenCL C 1.2
======================================================================

2) What's the version number that shows when you run the miner?  It should look like
Code:
xptMiner (v1.X) + GPU Metiscoin Miner (v0.Xgg)

3) What command did you use to launch the miner?

4) What operating system and what program version (32-bit or 64-bit)?

Ideally, you can capture all three of these things with one screenshot.  It should look like this.

If you are getting compile errors, please include the compile error log.  You can embed it in [code­][/code­] tags or upload it to pastebin.com



Note: If you have a ATI Radeon 4000 series GPU, this code will not work!  The 4000 series doesn't fully support OpenCL.  There's nothing I can do to fix that.

I've taken Girino's GPU miner for Metiscoin and optimized the hell out of it.
The new version is now over 3.5 times as fast.


19 February, 2014 - Finished a complete rewrite of the OpenCL code.  Now the miner is 15-20% faster!
Get the latest version from the download section below.  The changes have been uploaded to github.

12 February, 2014 - The issue with "invalid shares" on the 32-bit build has been fixed.
In addition, the "-s" flag was added to allow adjusting the GPU load.  Run "xptMiner" with no flags for more details.

10 February, 2014 - New version has been released!  Please re-download your miner!
The update includes a 5% speed bonus along with some additional debugging information for device troubleshooting.
Download links remain the same.
