Wolf's XMR GPU Miner

[c2n14]

Maybe try 16.9.1 drivers?

They're perfect for my Win7-64 and this miner.

Edit: I have RX 470.

[gegstore]

low difficulty share, all rejected

this miner is no good the old work best, i am sorry for you

[mycoinsstore]

low difficulty share, all rejected

I confirm this.

2X ATI Radeon R9 270X with latest 13.9.1 drivers.
My config:

Code:

{
	"Algorithms":
	[
		{
			"name": "CryptoNight",
			"devices":
			[
				{
					"index": 0,
					"corefreq": 1250,
					"memfreq": 1250,
					"fanspeed": 90,
					"powertune": 20,
					"threads": 1,
					"rawintensity": 511,
					"worksize": 8
				},
                     {
					"index": 1,
					"corefreq": 1250,
					"memfreq": 1250,
					"fanspeed": 90,
					"powertune": 20,
					"threads": 1,
					"rawintensity": 511,
					"worksize": 8
				}

			]

With new Wolf's XMR GPU Miner version 0.4 I only get "Low difficulty shares, rejected"
With same config and drivers on version 0.3 I have no errors!

Oh, I forgot to say - system is Win7 Ultimate x64

Any suggestions?

Try updating drivers - new ones work better with this version.

Oh, excuse me for my mistake - I posted wrong version - I already have latest version 16.9.1 of AMD drivers!

@Wolf0

Thanks for all your work, is there anything else you'd advise doing in my scenario? I can try different driver version, but what specific version should I try?

Oooh, I might see the issue - your rawintensity is NOT a multiple of your worksize. Try fixing that - if it persists, then open an issue on GitHub, please.

Unfortunately, it did not help. 
I tried rawintensity from 500 to 600, but error was the same.

And btw, in yours miner version 0.3 my config with "worksize": 8 and "rawintensity": 511 works perfectly and gaves me 445 h/s on my R9 270X!

So?

Great miner.

With a few MSI Gaming X RX 480 @ 1304 on a research rig (Win10), I get identical speeds to Claymore with some RI/WS tinkering: https://i.imgur.com/3RutBrm.png.

One change request: a quiet mode (analagous to -q) whereby only successful shares and total hashrate is reported would be extremely welcome.

Thanks

[mysongranhills2]

Tired older drivers 16.20 and still getting the same error that says I should never see it??

[mysongranhills2]

Uninstalled, cleaned and reinstalled 16.20. Same result.

Tried Claymore's and was able to get it working @ 615 h/s for what it is worth.

Still hoping to get this one working.

16.9.1 - Working.

from what i understand OpenCL is not working on 16.04 yet? that's why i had to go back to 14.04(and .4 not .5) which did not work well either with AMD's SDK for me!?

It works fine on 16.xx - AMDGPU-PRO.

will give it  shot now ... here comes another OS test !!

sorry, but a quick unrelated question, I will install the desktop edition (16.04.1) and then install the AMD SDK? or is it all included the the AMDGPU-PRO?

Would newest drivers 16.3 do any difference? ( was forced to use the disc that came from MSI because AMD's 16.3 drivers would freeze/crash windows after ~15 seconds after logging into my computer )
Any suggestions/tweaks?

Installed ubuntu 16.04.1 desktop and amdgpu-pro and tested it on repo bfgminer, it did not see my card, so i compiled cpp-ethereum and ran its benchmark and thats what i got:

mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ ./ethminer -M --opencl
[OPENCL]:OpenCL device Spectre has insufficient GPU memory.1057591296 bytes of memory found < 1423739904 bytes of memory required
No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ export GPU_FORCE_64BIT_PTR=0
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ export GPU_MAX_HEAP_SIZE=100
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ export GPU_USE_SYNC_OBJECTS=1
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ export GPU_MAX_ALLOC_PERCENT=100
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ export GPU_SINGLE_ALLOC_PERCENT=100
mylin@MyLinMiner:~/Miner/cpp-ethereum/build/ethminer$ ./ethminer -M --opencl

usually on ubuntu 14.xx the export statements covered this memory problem, but it seems that they dont work on 16?

and listing devices it gives me this:

[OPENCL]:

        CL_DEVICE_GLOBAL_MEM_SIZE: 1057591296

so, actually the spectre card is the internal one, and its not seeing the other HD 5450 card?

Thought i would share my numbers, i just cant get anything near claymore's miner ( ~620 h/s )
Windows 7, 16 gb of ram, 16 gb of pagefile,
MSI RX 480 8GB , AMD drivers 16.20 , stock clock [ 1300 / 2000 ]
Any suggestions/tweaks?

Win7x64 /// crimson 15.12 /// hd7970 (1000/1500) /// k-miner

As I have stated above, I get around 590 H/s per RX 480 4GB stock card.

However, I have encountered an issue.

This miner refuses to start if an NVIDIA card is used as primary video driver. My current setup is an NVIDIA 1080 on the main 16 slot and then multiple rx 480s on risers from the other slots. Due to work purposes, this cannot be changed.

I have tried multiple changes in the config file.

Any hints?

Can someone who has it working state their driver version? I'll see if I can fix the issue on the problematic ones.

hi there wolf ,
i am not able to use claymore's miner because my AMD card ( HD5450 ) has a MAX_WORK_SIZE of 128   and not 256 , will i be able to use your miner ?
thanks for answering

i like the summary at the top, you use k-miner for Win64 ? can you provide link to download that miner?
or is it something you have to put in the xmr.conf of wolf's miner?

i would like to have more details,
thanks

I have a faster kernel set, too - my goal here was to equal Claymore, not exceed it.

Oops!

mATX with two pcie slots from 2008:



In my case reason for those low difficulty shares was too much undervolting.
