Best part is, I hear Nvidia won't get to use the new memory tech for the better part of a year. The first ones will probably be 28nm, but if they do get a die shrink too, it'll slaughter the 980Ti, I bet.
good. More cores, cheaper price. What do you need the memory for? Scrypt mining? cryptonight, lyra2re, scrypt-jane.... |

Lazy..
The windows builds produce more hash, and use less power. You can get 100% more profit if you switch to windows.
reason why I'm not buying nvidia: amd drivers for linux are bad but the situation with nvidia is even worse. another reason is I wanna see the r9 3XX in action before buying for the winter. Take it as a rumor for now but the only cards probably worth it will be the top of the line 3xx. http://videocardz.com/55499/amds-hawaii-gpu-to-return-with-radeon-300-seriesif amd are going the way they did with 7970 etc which were rebranded ( and that was it for the first round - just a rebrand ) as 280x - then for the next 6 months - we will not really see anything worth the while ... unless of course they decide that an actual rebrand AND redesign is what they will bring out ... but its all conjecture for the moment ... would be nice for a redesign though ...  ... #crysx R9 300 series will not be a rebrand only: there is new memory technology and other goodies; but they'll probably, at least intially, still be based on 28nm tehnology. |

in beginning of this thread: "Sorry for the confusion. I am responsible for the official discussion and this is the last (official) thread. This will also get updated more frequently." so even more confusion and the information spread here and there... nonsense :-) |

Is that the latency problem all over again?
Lyra2RE does random accesses: some are even based on the previous results. So it is a mix of latency and bandwidth but I'd say more latency than anything else. |

The whole reason I asked about Lyra is because I'm using Miner Control to help keep my connection to yaamp. It works great, took me some time to get it to run, but does, according to price, switch to that algo.
I think yaamp normalises prices based on AMD HW, as do most profit switching multipools. Some algos are way off compared to ccminer. Looks like AMD gpus are best on lyra2re, see my miner in the signature (r9 290 almost 1.8 Mh/s and about 200W). By extrapolation from the 750ti the 970 could match that @ 145 watts and a 980 2.2 Mh/s @ 155 watts, It doesn't work like that - 750Ti tends to be the absolute best of the three in hash/watt... And Lyra2RE depends heavily on ram speed: just think that r9 290 and 290x are virtually equivalent, regardless 10% more shaders. Kinda like scrypt. Thus, I don't think the 980 can do 2.2 Mh/s, probably half that. |

in general, overclocking should bring better power efficiency, unless its effect is counterbalanced by automatic or manual overvolting, or by additional power draw from the cooling system (fans).

Windows has its drawbacks, but I can also say that I ran a Windows XP machine in 2001-2002 that was overclocked 50% (1GHz Athlon @ 1.5GHz), cooled by air, and had an uptime of more than 6 months. And that was running Folding @ Home when otherwise idle.
Windows machines can be just as stable as any other OS, if configured correctly.
It depends on what the machine is running. I had linux servers with uptime of over 3 years (running cpu and hd processes all the time). There are countless reasons to favor linux (remote admin, system updates...) and you can find many for windows as well. But all of this doesn't matter: if you are good on windows, or if your application runs on windows only, you'd better use it ;-) |

wow lotta donation hashing! :-D
and only one user saying thank you.
but of that 90 users on nicehash lyra, surely a nice part is using my miner.
(this makes me think I should switch to nvidia, much more grateful users there)
ooooooo why am I saying this over again? I should know by now!!! :-D

It is also possible to mod the kernals so that they use less power...
Look at my whirlpoolx mod. The Threads per block was reduced from 1024 to 512, and instead I computed more than one hash per thread.
When I reduced the number of threads, I got a lower power consumption and a higher hashrate...
doing that with sgminer is not trivial. maybe with a custom miner ;-) |

A tip for the guys who use older drivers with wolf0's binaries.
Since this build is made for the latest drivers, I think you need to copy the latest opencl files(omega dll's) into the sgminer folder before you run the miner.
Or upgrade. But an upgrade could cause the other algos to run at 50% speed.
You should just need to copy the newer opencl.dll (or libopencl.so on linux) in order to make your own bins. I forgot to say that if you want to use libopencl.so from a different driver on linux, you can't just copy it. Better put it in a related directory (say "/usr/local/lib"), run "lddconfig" on that directory and check it with "ldd sgminer". |

Thanks m8, i'll try when i have time ) Don't forget to report (thanks) and mine a couple minutes with my setting. It'll be just a bunch of satoshis, but it makes my day, because I know that someone appreciated my work ;-) |

Or driver. Which driver is the best? 14.6 rc 3?
I've developed the miner on omega drivers (14.12). |
|

Could be an issue with the 285x: it's a different chipset. |

I found A link in this thread would be very useful ☺ |
|
|

and where we can download sgminer.exe for your sources?
Look at my avatar :-) Jokes aside, if someone provides a windows build, I'll be grateful. I could do it myself but it takes time, my machines are all on linux. |
