Strange, if I set anything higher than 32 my MH/s go down! Hmmm..
Perhaps it's because I'm running two Fury X's on one system?
I tried enabling/disabling crossfire and Freesync. Both settings made no difference in speeds.
Are you overclocking your unlocked Fury? What OS are you running? I'm still a good 4-5Mh/s slower than you.
I run Windows so I've been using the miner recommended by coinotron for Etherium:
https://coinotron.com/app?action=help
I still have a bunch of Win 8 systems that were first setup for Litecoin and was happy to find that they could still mine Etherium with Catalyst 14.4 which is the last release for Win 8. Other systems running Win 7 are using the Crimson drivers.
Fury is OC @ 1050/550. Win10 latest insider build. Eth 1.1.3
I wonder if it's possible for you to launch two mining instances, one for each card instead of running them from one. I used to do that for Bitcoin so I could track my 2 GPUs and 1 FPGA separately.
Hmm. I wonder if a 10% memory bump is making up some of the difference. IIRC mining is super memory intensive. I can always pull out a card and test just one for now if I have issues getting two copies of ethminer to run.
Good times. Hopefully the price stays up for a month or so as I'll be able to at least pay off my MSI 390
The memory bump has a big effect on the GPU overclock effectiveness in games too.
Switched over to Dwarfpool. Running their stratum proxy setup. Their approx speed has me sitting @ 39 Mh/s. HBPPS setup.
Wow. Been out of the mining game a while, never heard of HBPPS. This week I'll do more testing (including checking out Dwarfpool) hopefully tonight.
Careful on Dwarfpool... it is getting flack for hacking the most amount of users on it (41% of network). It isn't good to have any pool having more than 20-30% IIRC, mainly because it becomes critical at 50% or more.
See here for top miners (pools): https://etherchain.org/statistics/miners
Your firewall may be blocking the traffic?
There are some switches you can try.
First make sure you add this. It will get on new work faster. --farm-recheck 100 default is 500 (in ms)
You can also try to play around with the global and local work values.
--cl-global-work 4096 default is 4096, try 8192 or 16384 also. I use 16384 personally.
--cl-local-work 64 default is 64. 128 and 256 can be tried. I read some dev chatter that 64 was the most efficient for AMD because their wavefront is 64 threads. Nvidia should use 32.
Please note, there are not big gains to be had like tweaking for BTC mining.
FYI my 2GB 5870 fails to start due to "insufficient memory". Anyone else here with 2GB card get theirs to work? This card uses to kill it at BTC mining, would be a shame not to use it.
Where are these settings located? I'd like to see if your suggestions help.
Thanks
You launch the miner with them. Have you not read the documentation or help files?
Are you referring to the statements you type in cmd to start mining?
Hello. I'm trying to mine with Asus R9 380, but I'm getting error : "No GPU with sufficient memory was found. Can't GPU mine". Running Newest Crimson drivers 16.1.1, card has 4GB of memory so that should not be an issue. Anyone can give me advice please?
Sometimes if you have an igp it can mess with the miner. If you have one, is it disabled in the bios?
You can also try --opencl-platform instead of --opencl-device to see if that works.
Hey! That seem to helped. GPU is doing something now!! Your the star thank you.
Aha except I just noticed it was using CPU to mine and not GPU, when i set it up with -G it is the same error.
On windows? Which version of ethminer? What cpu?
At the end this set of arguments helped --opencl-device 0 --opencl-platform 1
Previously I only tried one or another.
Just one more newbie question. If I do want to solo mine, coins mined goes to my wallet in geth always or can I add address to mining command where I want them to be potentionally send?
No. Again, you need to RTM. You first create a wallet/address/account. The coins mined are sent to that wallet/address/account.
