hi claymore

I'm using ubuntu 16.04 with and 16.60 driver
only get around 150h on an rx480 8g
try the different setting but no luck.
working fine on windows.

any idea?

Same OS and driver as me, but I have R9 270X and only getting 10h/s. I think it's all down to needing the exact right OS and driver combo as per Claymore posts. I think you have to use 15.10 and proprietary AMD driver (Ubuntu 16.40 uses new amdgpu-pro stack). Can't get any of my other zcash miners to work at all on this set up.

I have rx480 , ubuntu 16.04, 16.60 drivers and doing 300 H/S on my card. Maybe reinstall OS/drivers. My 380x on same rig doing 193-200H/S. Any problems I mentioned before had nothing to do with Claymore - all Hardware issues like bad risers. Claymore makes a solid product.

Thx. Have tried again and now getting ~66h/s with my 270x.

I have two R9 270 (not x) in a Linux 14.04 box with the 15.12 drivers. Using 12.3. I am getting 172 H/s for each card.
Make sure you set the environment variables as stated in the readme (see script below).
When the zecminer64 starts it reduces the intensity to 4.

bash script:
#!/bin/bash
export GPU_FORCE_64BIT_PTR=1
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100
/home/me/ClaymoreZCashGPUMinerv12.3/zecminer64

Yes I have all of those set in my start.bash. Mine auto adjusts the intensity back to 3:

Code:

OpenCL initializing...
AMD Cards available: 1
GPU #0: Pitcairn, 1688 MB available, 10 compute units

GPU #0 is going to use too high intensity (6), not enough GPU memory, intensity value reduced (3)

Looks like your 270x only has 10 compute units and memory is limited.

This is for the 270 cards:
