AMD RX470 - Speed only 580 hashes/r

imrecsoka commented 6 years ago

Hi, i seem to get low speeds using XMRIG AMD:

I normally get 650 hashes/s with Claymore or SGMiner - so about 1900 hashes for 3 cards with 4GB ram.

Is this a known issue

What are your settings for your RX470 in config.json ....?

i'm getting slow hashing from my 580 as well: [2017-12-31 15:22:19] speed 10s/60s/15m 572.9 572.9 568.7 H/s max: 573.5 H/s [2017-12-31 15:22:19] GPU 0 10s/60s/15m 572.9 572.9 568.7 H/s [2017-12-31 15:22:19] speed 10s/60s/15m 572.9 572.9 568.7 H/s max: 573.5 H/s [2017-12-31 15:23:00] speed 10s/60s/15m 572.5 572.5 568.6 H/s max: 573.5 H/s

my configfile is: { "algo": "cryptonight", "background": false, "colors": true, "donate-level": 5, "log-file": null, "print-time": 60, "retries": 5, "retry-pause": 5, "syslog": false, "opencl-platform": 0, "threads": [ { "index": 0, "intensity": 950, "worksize": 8, "affine_to_cpu": false }

Have you tried different intensity and worksize combinations? Usually it needs a little bit tinkering with the default values provided. I raised the intensity from 512 to 760 on my HD 7850 config and I gained about +50 hashes
