Re: SRBMiner Cryptonight AMD GPU Miner V1.5.9

For RX570/RX580
If 4gb cards. 59 intensity, wksize 8, dual threads
If 8gb cards 114-120, wksize 8, dual threads

Hi man + others

Thanks for the info, these are my new set of results; (double threads = true)

I cannot push this over 86 with 80 being most stable (5200+ hash)

ALL CARDS ARE 8GB

"gpu_conf" :
[
   { "id" : 0, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0},
   { "id" : 1, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0},
   { "id" : 2, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0},
   { "id" : 3, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0},
   { "id" : 4, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0},
   { "id" : 5, "intensity" : 86, "worksize" : 8, "threads" : 2, "kernel" : 0}
]
}

If I do I get this error:
Error CL_MEM_OBJECT_ALLOCATION_FAILURE when calling clEnqueueNDRangeKernel for kernel 0 for DeviceID 1 (Thread 3)

How much is your virtual memory set to? Make it at least sum of VRAM of each GPU.
Also in order to hash higher increase core clocks to 1250 range (voltages 875-925mV core, 900mV mem)

Also I don't have "kernel" : 0, in my GPU config settings. Not sure how that changes things.

Hi Man,

Thanks for the reply, you are correct my core clock values where bit low from previous setup to save power.
Ether mining different to v7 mining. I have now increased CC value to 1250 and 1000/mv
I have initial VRAM set to 34000 and 56000 Max - this should be plenty.
I'm getting more hash now with this new setting, see below. I know wonder if can increase intensity further due to changes.
