your intensity maybe a bit high also you could specify your worksize (--opencl-launch=22) 0,64,128,256
Give this a try. > wildrig.exe --algo hex --opencl-platform=1 --opencl-threads 2 --opencl-launch 21x
128 --strategy=
1Next try > wildrig.exe --algo hex --opencl-platform=1 --opencl-threads
3 --opencl-launch 21x
256 --strategy=
0.. etc..
Take speed readings of hashrate faster 300 shares or whatever. leave it run to get a good avg. (not just peek)
Rinse & repeat.
I haven't done much reading up on either HEX algo nor, Phi algo so I need to find out what exactly either of the algo's prefer.
- Are HEX | Phi memory intensive ?
- Does the Engine speeds affect the hashing of the algo's above?
- Can GPU engine speeds be reduced to save on power (as an example) Drop Core from max to 80% of max without it affecting hashrates.
These are all questions which I must learn more about. its always good to understand deeper as opposed to blindly setting mining parameters/options.
The name of the game is to mine the fastest speeds in the most efficient manner.
The only thing I can go on to help is to watch the hashrates on your miner if you see them bouncing around a lot after a couple of hundred shares have gone past lower your intensity.
Your Vega GPU's run HBM2 memory as opposed to RX470/80 570/80 GDDR5 so the settings I found work best will obviously be different to yours. However, i understand you are seeking baselines. As per your initial question.
Perhaps you can figure things out best by working backwards.
Start with lowest settings of everything
1 Thread
0 worksize
18 intensity
0 stratagy
Then ramp your settings up.
pick one setting to focus your benchmark on then increase. once you found fastest. sweetspot pick the next setting then ramp than up and so on.
Once that is done you can test with the Strategy=0|1 option.
--Independent GPU's over multi-gpu as one device.
so every GPU(or thread of it, if use --opencl-threads) work in its own range. Using strategy 1 all GPU's will work as one device
As was said previously by someone its had to actually benchmark as the algos change.
An option could be to benchmark in sgminer-kl or whatever other miner to find exact best speeds using the "--benchmark BBBBBBBB" <<= (change to match hex algo)
Find a miner where you are able to issue the --benchmark command.
Finding optimal settings in that miner and then port/copy your findings /config over into wildrig (for as close as possible match) [Just a suggestion ;]
Good Luck.
I will post my fastest settings for all the algos when I have a finished.
FYI:
I also undervolt and down clock Core speeds for ETH. But sometimes I forget and start to mine another algo. Phi|Hex|X16r etc and my undervolting causes miners to crash. -- just a FYI kind of thing
