Yup, I knew that, but thought the gpu_conf section overwrote the global settings outside the gpu_conf section.

Ok, figured out my issue.  I had intensity: 0 in the config, and specified a GPU-specific intensity (112).  Once I removed the gpu_conf section, it worked perfectly.  Don't know if this is a bug or a change in how inheritance works in the config files.

WOWnero(CryptoNight V2), so CryptoNight V8 is CryptoNight V2?

There is a rough template on the first page for some cards and algos

i know how to set intensity and threads.
i need to know only worksize. I always set 8 to worksize.

I have a farm with 35 rigs: RX550 2GB, RX470 4GB and RX570 4GB

stellitev4

RX550 2GB
RX470 4GB
RX570 4GB

it will be wonderful if you write worksize values for the different graphic cards in readme.txt

For me too. I have a Rig with 6x RX550 4G. I mine Monero (CN V7) with 34 Intensity. 8 or 12 worksize change nothing in hashrate. I get arround 2900 hahes with this config.

Hi doktor83
Starting with version 1.6.5, on the normalv7 algorithm for R7 370 uses kernel 2 and give me 360h/s
On version 1.6,4 and earlier, these cards work on kernel 1 and give me 440h/s
What to do when the algorithm changes to normalv8 ?

is it important worksize in config ?

i tried 8 and 16 and 12
i think no any effect. any idea ?

Could anyone help me,when i start the miner with my r9 290 i get the following error:

[2018-10-09 14:48:01] Error CL_LINK_PROGRAM_FAILURE when calling clLinkProgram [ctx->Program] for DeviceID 0 (Thread 0)
[2018-10-09 14:48:01] Error CL_INVALID_PROGRAM when calling clGetProgramBuildInfo for length of build log output for DeviceID 0 (Thread 0)

Nice Dok! Can confirm ~2035 H/s for a V64 on V8. ~2135 H/s on current V7. V8 Only works using your pre-compiled kernels though. Running 18.6.1 drivers which are recommended, strange that they can't compile for V8. Just wanted to pass the info along, thx for all your wonderful work, best CN miner in my book by a long shot!

What intensity/worksize/threads combo are you recommending on RX 570's 4GB for the new v8?

check new version/ same trouble ((
also check without precompile binaries. same low rate 900-930 not 1000+ as on 1.6.7
possible need other drivers? use 18.3.4

I don't understand you Doctor? That GPU_conf part is rock solid in V7 algorithm for 7 days with 7070 H/s.
Same settings in SrbMiner and overdrive settings in V8 results with 4100 H/s in benchmark mode.
Do you need some more specific test, i can test it?

Downloaded again and tested Maxi version with driver 18.3.4 and 2 Vega 56 Reference card, one Vega 64 Asus Strix and one Rx 570 GB.

Vega problem is still here. Low performance about 4100 H/s for cards (on V7 is 7070 H/s with same settings).

{
"cryptonight_type" : "normalv8",
"intensity" : 0,
"double_threads" : true,
"min_rig_speed" : 6500,
"gpu_conf" :

   { "id" : 0, "intensity" : 120, "worksize" : 16, "threads" : 1},
   { "id" : 0, "intensity" : 120, "worksize" : 16, "threads" : 1},
   { "id" : 1, "intensity" : 56, "worksize" : 8, "threads" : 1},
   { "id" : 1, "intensity" : 56, "worksize" : 8, "threads" : 1},
   { "id" : 2, "intensity" : 120, "worksize" : 8, "threads" : 1},
   { "id" : 2, "intensity" : 122, "worksize" : 8, "threads" : 1},

   { "id" : 3, "intensity" : 120, "worksize" : 16, "threads" : 1}
]
}

That is from benchmark test 60 sec, but problem is there.

nice test. try Worksize 8
my vega64LE have better HR with 8 worksize

true.
but have trouble on cn-heavy with rx470\480\570\580 8gb card. plz check my config
