offtopic, but the "outstanding" 750Ti power savings vs the 280x or 7950, are a fallacy. Yes, in the end, the 750Ti still wins on hash/W, but it's misguided to tune the Tahiti card to max out hash speed, set whatever voltage you need to achieve it, and then complain it is not efficient!
If you want low power, you tune for low power! (and low heat and noise). You undervolt to whatever low voltage, e.g. 0.85V(?) to 0.95V. This allows ranges dependent on leakage, VRM and ASIC quality, but let's say 800~1030 Mhz core, 500~700 Kh/s at 110~150W. That's scrypt. If you mine others, you can cut up to 40W from the vram power consumption.
Not to speak of the lower density, the always present 100+W base platform overhead, the upfront cost of extra components per Mh/s, the higher cost of the 750Ti per hash, it's quirks when using risers, etc...
ontopic: of course it would be great for Nvidians to mine X11. I occasionally use my gaming/Linux GTX760 for mining, too.

Whatever side of the barricade you are, don't be misguided and ditch or smear Firefox. This is the last large open source browser, spyware free. Chrome phones home, IE is closed source. Some privacy or power-user plugins work better on Firefox. The Firefox code base is also used on TorBrowser. I could go on ... If you don't like Firefox because it's slow, look at http://www.waterfoxproject.org/Chromium is much better. Default web browser on Ubuntu, not firefox. Don't be misguided and support an open source project because people who share the JavaScript's inventor view are all bigots and so are you, holocaust denier!!!! Yeah right. I shall pass. The project is open source as you said. I shall wait for its forking moment, the apolitical ones, the LibreFOX version of it if that ever happen one day. OKcupid was targeting firefox users when they came to their website. How come you did not think it was misguided for them, OKCupid to play that card with the last large open source browser, spyware free project?Firefox crew supports Intel, who's employees voted for Prop 8 with their donation. Firefox crew supports Obama, who never said in his political carrier back in 2008 he was for gay marriage. Firefox crew supports Don't ask don't tell bill Clinton and his wife. Can't touch it. Tainted. Firefoxed. Don't worry. I am just but a lonely voice. People will still use firefox. Wtf is this "holocaust denier" B.S. associated with my reply??? Edit: ok, just read above. I don't make a big deal out of this cupid website or gay controversy, it's just internet drama for foreign people, I guess. I just don't want to see such a critical open-source project being dragged down |

Isn't this what the community wants? People like me who have a job and friends who have finished HIGH SCHOOL? New blood? Resources? If by "new blood", you mean someone that starts a shitty thread to fight against another shitty thread, no I don't think the "community" needs more of this. This is an un-moderated part of the forum. The only moderation that exists, is one's own common sense. Giving up of stupid threads, not posting and preventing their bump, that's a good way to help. |

I AM OUT OF THIS FUCKING FORUM. NO ADULT IN THEIR RIGHT MIND WILL TAKE CYPTO INVESTING SERIOUSLY WHEN CHILDREN ARE RUNNING THE HOUSE.
This isn't the proper forum for "crypto investing" in the first place. 1) This is a Bitcoin discussion forum, and the alt section is considered a "trashcan" 2) If you invest/speculate with serious money, there are probably better and more specialized resources. See for example https://cryptocointalk.com/ and http://www.elitetrader.com/vb/forumdisplay.php?f=67 I don't have an answer to the rest of your post, unfortunately. Cryptohunter behaves strangely, yes. |

rather than being a snotty little cunt ... Dude, please spare us of this kind of language. Make your points without resorting to it. gimme a break i have had 1000 vile insulting attacks on me in here this last month alone.. many of these guys hunt me and harass and troll me and never even make any effort to stay on topic in the slightest they think this is a free for all to quote and and attack spoetnik web site.. so gimme a break. i think i handle things rather well considering the monolithic amount of abuse i am subjected to here 24/7 YOU TRY BEING SUBJECTED TO THAT DAY IN AND DAY OUT ! i also don't swear much but i get picked apart here by rabid vultures with anything i say non stop ! and i have seen a million people swear so if it's such a problem then why is sooo many here doing it besides me ? maybe you guys should grow up and fuck off and get off my god damn back and quit quoting me and harrasing the hell out of me ? seriously do i hunt and stalk and harass any of you people ? grow the hell up. and quit worrying about quoting me and running your damn mouth.. stick to the topic or fuck off . I don't care what you all think of me i care about what you think about what i said in regards to the topic at hand... and that guy has been a huge massive mouthy jerk to me a 100 times before on other topics in case you guys didn't notice.. want me to go find them and show you all ? ..he's a mouthy scam defender. I understand. I take your points seriously and read what you and many others have to say, and also don't like to bring moral high horse B.S. Further, being a man and not native English speaker, I easily shrug it off and some drama even amuses me. But not when this reaches the level of spam, and derails threads and discussions, though. Then people attacking you today, are sometimes the same ones that you attacked and insulted last month, for frivolous or no reason at all. What kind of new person in this forum, posting without bias or agenda, trying to learn and understand stuff, likes to be attacked? |

So I decided to return MSI GPU to store I bought it, I can return it in 14 days from purchase, and change it to Gigabyte GPU same or higher type. ... PS: I have one question from different topic, I Tried to mining in GPU a CPU (it is about 120 kH/s :-) but when I power on GPU mining and power on CPU minig, the hash of GPU fall down to about 250 kH/s - 350 kH/s, my question is WHY  :-) Yes, that was a wise decision. Peace of mind is priceless... Regarding CPU mining, you must always leave 1 thread free, set the priority of the CPU miner to idle, run the GPU miner at high priority, or even all of those. That is to leave the processor free to run the GPU miner and allow it to quickly feed and grab work from the GPUs. Most miners have a -t parameter to set how many threads. Set the value to the # of CPU cores - 1. To lower priority, use task manager or Process Explorer. Or in a batch file, use start /low minerd ... Make sure CPU mining is worthwhile, though... |

I voted for Heavycoin. Very nice on the GPUs, implemented for ATI and Nvidia with good optimizations (2 prestigious programmers ended up "competing" for speed increases), no marketing or drama associated like there seems on X11, etc ...
The only I wouldn't want is the one winning, Scrypt-N. Even more heat, power use and component stress than plain scrypt.

Then you had made a better deal buying the coins instead of mining them, your logic is not solid when it comes to business...
The OP is addressing the ones that already invested in mining rigs, I suppose. With mining, as mentioned, you just pay to the power company. You can also pick low difficulty, adjust power usage, play around with rigs and hardware, etc... Buying coins requires other kind of skills and issues, dealing with crappy fiat -> btc gateways and exchanges, compete with day traders and bots. Mining is a mix of business and hobbyism. |

So, how's progress with TorrentCoin ?  |

Seriously, cryptohunter, what are you trying to accomplish in this thread? Do you want a technical discussion, or more drama?

I try to update GPU bios, but I never did it before :-)
Is possible, that GPU card is broken ?
Use --gpu-vddc 0.95 --gpu-engine 900 and see if the cards respond to undervolting. If not, use http://event.msi.com/vga/afterburner/download.htm to undervolt the MSI, and maybe Gigabyte OC Guru. With the software, there's no need to mod and flash the bios, but sometimes they don't work. 950 ~ 1000 mV or so should be ok. You will lose a bit of hash rate, but preserve the cards. When using cards to mine inside a PC case, temperatures can really be terrible. Remove the side panel and point a large household fan to it. |

I burned precisely the same motherboard that way. I'm now a proud owner of a spare i7-870  |

I don't see where's a serious bottleneck or some conspiracy. Since X11 (and hefty, keccak and those others from sph-sgminer) is not memory hard, you're not stressing the memory controller, L2 caches and the ram chips.
You're used to scrypt, see it as a "reference" and say that others must not be optimized due to low power use and thermals. However, scrypt is the odd one out in the first place, a complete card fuck like Furmark or some videocard stress test.
Interesting.... since i'm not "clued up" with the design and workings of gpus... let's explore that idea further. I like to learn things... I say nothing.... i am asking. So just that i may understand what you are saying..... scrypt is stressing parts of the card harder than these other algos. The memory side of things in simple terms. Scrypt is memory intensive so it uses full memory bandwidth etc and can force the card to it's full limits. More heat and electricity used. You are saying perhaps these other algos because they are not memory hard and do not stress the memory to it's full potential..... however the gpu could still not process these algos any faster not because the memory is being fully used but because other parts of the card are already stressed to the max. Therefore unlikely any more optimisation is possible regardless of the mining software? Is that what you mean? This is what i was asking about when i was saying is there a bottleneck...........i mean surely if you could increase the cards calculating potential in all other areas except the memory parts then eventually the memory would be saturated by solving these new algos right? there is some part of the card holding back it having all of it's memory resources being fully exhausted? Is that what you mean? Yes, basically what I mean is that there's actually nothing useful to be done on parts of the chip. Scrypt is stressing more parts of the videocard, that's what I know for sure. Regarding if some things could be done to get more hash out of a card, if there could be better load distribution or work around existing bottlenecks, that I don't know. To give you accurate not half-assed answers though, I would need to dig deeper into OpenCL, hardware articles and ATI/AMD manuals. I'm very tempted to do so, when I have some free time and peace of mind |

I'm too tired atm, perhaps I didn't understand what you mean ... I don't see where's a serious bottleneck or some conspiracy. Since X11 (and hefty, keccak and those others from sph-sgminer) is not memory hard, you're not stressing the memory controller, L2 caches and the ram chips.

But that's the point. Imagine if I optimized a game to push my GPU as hard as Furmark does just to squeeze some extra work out of it. Both of us run the game and while you get 32 FPS using the exact same hardware as I am, I'm getting 48 FPS due to my secret optimizations under the hood. I know this is a very terrible analogy, but think about it. None of this would be a problem if pushing the GPU or limiting the GPU is a user choice, much like scrypt. Let's say I mine a Scrypt coin and get 500Kh/s on my GPU stock, but if I OC and OV some I can push it to 585Kh/s; now durring the summer months this might be a problem where you live due in part to extreme heat, increased electricity price and increased power consumption, so I go ahead and underclock 50% and undervolt to about 60% and now get 255Kh/s. This makes sense to me; what doesn't make sense is claiming 50% less heat and power consumption while still hashing at full capacity. Well, it could be hashing "at full capacity" with less heat, because the hash code is different. There are parts of the chip left unused, the code itself doesn't demand operations from what's memory related. There are not random addressing jumps like scrypt. Those parts just sit there because they just have nothing to do, while the arithmetic core is already at 100% usage. I'll try to give a counter-example; the so called "CPU only" Heavycoin where the devs struggled to destroy paralellism and prevent GPU mining. It took 2 weeks(?) for the first heavycoin GPU miner to be mentioned. cgminer-heavy work-in-progress (that one needed to compile from source) could only reach 7(?) Mh/s on a 280x in the very beginning, then it raised to 11, to 15 Mh/s and I don't know how much it is now. Christian's ccminer could reach 13 Mh/s on a 750Ti and for a few hours it beat a R9-290. Reorder had to program, operate the pool, go on with his life, etc... Was someone holding the R9-290 speed vs a simpler 750Ti due to a conspiracy? No, of course not. It takes massive brain power, time, skill and personal effort to optimize miner code. Now, go and mine Heavycoin at the maxed out performance, and look at the temperatures. Of course, I'm not trying to distract from the possibility that there are secret X11 miners out there and a few guys are mining at much higher speed than the rest of us. It could be! There have been lots of suspicions (or even confirmations) regarding private miners or optimizations during last months. However, that's a different discussion from what I'm trying to get at here. |
