worksize: 192
rawintensity (rx 470): 1916928
rawintensity (rx 480): 2156544

You should try different intensities to optimize your hash rate

Thanks for response!
I'm under Windows and with above settings I have 9.8 mhs only (with Claymore: 22 mhs) per card ;(

This is what I put in the config file:

Code:
    "profiles": [{
        "worksize": "192",
        "name": "eth",
        "algorithm": "ethash",
        "gpu-threads": "2",
        "rawintensity": "1916928"
    }],
    "no-extranonce": "true",
    "default-profile": "eth"

Any thoughts?
TIA

I have no windows rig for testing, but I guess that 'gpu-threads: 2' might be the problem. I would start at 'gpu-threads: 1' and 'xintensity: 4620' because I'm not sure whether sgminer accepts rawintensity much larger than 2,000,000.

Wow, thanks! Now we are onto something Cheesy

With the below settings:

Code:
        "worksize": "192",
        "name": "eth",
        "algorithm": "ethash",
        "gpu-threads": "1",
        "xintensity": "4620"
    }],
    "no-extranonce": "true",
    "default-profile": "eth"

I got this:



Hashrates are close to Claymores - but they could be a little better Wink

Just those HW errors Sad - Any ideas?

HW's are normal, as long as they're trickling in and not skyrocketing, it's all good.

@OhGodAGirl

Big thanks Smiley

My last questions:
1) sgminer shows hashrate like this: 21.70M/20.21Mh/s - is this 20.21Mh/s my card's hashrate? I got 22 Mh/s @ CM ...
2) WU: 20-21/m for such hashrate - is it OK?

The first value is an exponential moving average of your hash rate. Therefore, this value is a good measure of your current hash rate after a few minutes. The second value is an average over the whole run time and it should be equal to the first value after a few hour, if the pool connection is stable. One Radeon RX 480 8GB does about 23.8 MH/s with stock clocks and your card seems to be close to 21.7 MH/s (you have to run it longer).
The WU (work units) are used to calculate the number of HW errors. Let's assume your card mines with an average of 20 MH/s and has an error rate of 2%. Then the expected WU value would be 20/m * (1-0.02) = 19.6/m. The hardware errors are normal, but they aren't shown by other Ethereum miners. A defective card typically produces 10 times more hardware errors then a working one.

Genoil's ethminer does report hardware errors.

Why is the miner abandoned? I'm getting higher hashrates than Claymore's and it's open source! A really good piece of software right there, apart for CPU usage.

I told him to use SSE in the regenhash, but NOOOO... it should work on *ALL* the CPUs...

That's the wrong conclusion. The high CPU usage only happens on Windows, so that one core shows 100% usage. Regenhash is executed every ~2s with one GPU.
It seems to be a bug in libwinpthread because earlier sgminer had this issue on Windows, too.

I am still playing with settings on a 390 and 390x and have yet to find any settings that come close to Genoil or Claymore's.  I am using 15.12 and have tried a full range of xintensity and worksizes and the best I have done on running it for an hour per setting is about 26mh.  So far definitely not worth converting the farm to it yet but I am sure it will be when I find the correct settings.

Usually when I have problems setting up something it's because I have overly complicated the task--

I get similar/marginally higher speeds using stock settings using 1 RX470 + 1 7950. Also when moving the kernel into my fork. It's good!

Need to try that out, except yours doesn't have API support to use with AwesomeMiner - I wish it did Wink

Oh, my builds actually don't do that. Ever. It is pthread.

Even with no hash improvement, lot's of operational info in one place.

I take it that the ability to use the GPU-vddc command, will be card dependent?

Up to 31.2 on a 390x running 1100/1250 - definitely making headway.  A little more tuning and we have a winner Grin

I'm getting steady 30MH/s on each Fury X on stock clocks (1050/500). Claymore's can only get about 28MH.
A 390 at 1040Mhz gets 29Mh, with some overclocking I can surely can 32-33MH, but my cards warm up too much. Definitely the best miner out there.

The only issue I can spot is the CPU usage, which makes this miner basically worthless on weak CPUs. I couldn't run it on a single-core AMD CPU and a friend of mine had his rig crashing with a dual core Celeron installed. most mining rigs have very weak CPUs, and if this miner gets updated to support them, I am sure it will get much more traction.

I can fix it with a new binary - just needs to be recompiled against a better pthreads lib.
