i've lowered the tdp, now it consume at max 170w, but the ratio is the same, if i lower more to 130-150w, the hashrate will suffer, so there is actually no point in lowering it, besides having cool temp(now 64)
150w = 1250 megahash, 170w = 1300 megahash, mining decred
Sounds about right. This thread is about ETH mining profitability so opposite to DCR the most important thing with nvidia & ETH is overclock your memory. Put your card to P0 state to get access to memory speeds above 3005 MHz, OC your mem, play with core and tdp. Find combination that works best for you. Sometimes insane combinations give best hash/ watt performance. |

No offense, mate!  I must be wrong with your power consumption. Some 970's have 225w or 250w bios from factory. Nvflash and Maxwell bios tweaker are you friends if you really want to know what your card has eaten. Just flash no limit bios and post your wattage after that There is no point in going so far as to screw with the card's bios. I'm not a professional gaming overclocker, but we're not playing video games where losing a few pixels here and there doesn't matter; submitting good data is all that matters. Acceleration of mining ethereum has less to do with pushing the architecture's balls to the wall, sweating high wattage/temps for nothing, producing bad nonces and getting no submits. These cards run mem at 3700MHz+ with no errors, keeping temps in the mid 60's (read longevity), and produce 21MH on very low wattage. Had to take a look at SSC Gaming ACX 2.0+ bios power table. Default 170W OC 110% 187W |

i can not believe that his 970 consume only 90w, there is no way this is correct...
It is absolutely correct. Fact is, I cannot believe you have a 970 that can consume more than 145W, the max TDP of any GTX970 model, regardless of brand. Again: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-970/specificationsi think you're wrong, because my 970 power is 200w with oc, impossible to be 115w or even 90w lol that's too low, something is surely wrong on your end
What brand/model 970 are you running that shows it is using 200W? Or are you quoting your total system, card/mobo/etc.? Perhaps tonight if I get a chance I'll post some pictures/screenshots, since those are the only ways some kids can believe anything. Then we'll see what's impossible or not.  Or you could go over to the ethereum forums and ping anyone else who runs nVidia kit about their power profiles.  No offense, mate! I must be wrong with your power consumption.

yeah i have the g1 8+6 pin, you think that for mining is better to have a limited gpu with 8 pin only? what you recommend in this case?
edit..i was confusing the card i don't have the g1, i have the other gigabyte still 8+6 pin and oc by default
8-pin is the most hasslefree because you only need one pcie connector/ GPU from your PSU. With same clocks and wattage performance is the same as long as you are not hitting TDP limit. asus strix is the way to go i think, all i know is that right now my card is consuming almost 200w with factory oc, no additional oc i can not believe that his 970 consume only 90w, there is no way this is correct... Gigabyte G1 and Asus Strix consume same amount of power if you run them both on same clocks. They start showing difference when you OC and Strix hits its power limit and starts throttling, Gigabyte just keeps going because its power limit is way higher. |

It is possible to break 200w barrier with 970 but you need 8+6 or 8+8 pin model for that. 6+6 pin and 8-pin models are limited lower. Gigabyte G1 is one example of a card that is normally never power limited.
I still think bluebox has a little bit overoptimistic UPS. It is possible to gain nice power savings without losing too much performance with these cards but those number are too low. I might be wrong though.
Bluebox, try mem speed of 4000MHz or even higher, you should be really close to 22MH.

someone know the consumption of one 980ti because i'm consuming 200w for a single 970 oc'ed, if 980 do 2x the 970 but consume 300w with oc, it is much better to use
Can't be that much better, it's the same technology. You will get much better hashrate/power ratio on your 970s if you lower the TDP to 150 or less. decresing the clock from +100 to 0 or the mem from +100 to 0 will make me lose 100 mega, is worth it? I'm not talking about reducing clocks. I'm talking about TDP. The card can do a pretty good job at choosing the best clock for you based on the TDP you like. so is the ratio better at lower tdp? how i can lower the tdp if not by underclocking? i don't want to undervolt, with flashign and risky stuff like that As pallas said, play with those sliders. For DCR downclock memory and tdp (power limit), overclock core. See what happens Watt/ Hash. My rig likes P2 more than P0 with DCR. |

Yes it was the main reason for the 5%. I still need to compute them To be honest I thought 5% doesn't include tx fee BTW, what is the real minimum payout? Lowest I have been payed so far is 0.81 DCR |
|
|
|
|
One thing came to my mind, if you have set really low auto payout treshold then relatively high tx fees eat 4 x 0.05= 0.2 DCR from your daily earnings.

i'm using diff 8 on supernova, what should i use with one gpu only?
edit...seems better now, 10 hours = 0.7 decred, i think there was a problem in their end indeed
DCR is quite "slow" coin, last found blocks have about 4 minutes between them ( should be 15 but thats another story) so you are not in hurry to send at least one share to every block. Find settings that give you efficiency closer to 100%. If one pool doesn't work for you then try another one. Me and some fellow miners are reporting 99.8 - 99.85% accepted share rates at http://yiimp.ccminer.org. |

Fist ~44 hours with ~7 GH:
Accepted: 6490/6500 (99.85%)
Total earned 17.67 DCR

Added 6-7GH, hope it helps with finding blocks.
After quick testing it looks like I'm getting better poolside hashrate with separate instances. Maybe I just didn't let them run long enough?

Does this mean that if you already owned distribution and nodes, you can now own nethash too? |

Hi guys i want to try mining altcoins and i want to know if its possible to mine on this old PC:
Processor: Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz (4 CPUs), ~2.7GHz
Memory: 4096MB RAM
Display: NVIDIA GeForce 9600 GT
If its possible to mine something, what software i need and what coin do you recommend to mine?
If you want to try GPU mining you need to upgrade your 9600 GT. Used nvidia 750ti or amd 7970/ 280x is the cheapest way to start, you maybe need more powerfull PSU for amd though. I'm running my cards on very old hardware and they work just fine. |

Too low performance and too high power consumption to be profitable miners any more.
Even the 7xxx series are getting pretty marginal at best.
My 6990 (basically 2 x 6950) is mining decred 2 x 800 Mh/s and earns a couple of DCR per day, even 58xx series is profitable in DCR. 7970 (=280x) is about the best card you can get for ETH mining. Street price about 140 €/$ and mines ~22MH, with todays prices ROI in 40 days. Only decred. 500-550Mh/s with one card.
I got 2x a HD6950 in my rig. Do you maybe know why cgminer is telling me they are hashing both with about 1200mh steady, and in every pooldashboard i check they are jumping up and down between 400 and 800? Use --vectors 1 switch in your launch config, otherwise 5000 and 6000 series show doubble hashrate. If you want you can try to flash those to 6970's, many of 6950's have locked shaders. So it wasnt running 1200 mhz als cgminer says, its actually running half of that? Would the increase be big when i flash it? Feel like walking on thin ice when talking about percents in this forum section... 1536 vs 1408 shaders so you can expect about 9% increase in hashrate. Is that BIG increase? I will leave it to you to decide. At least it's free. http://www.techpowerup.com/articles/overclocking/vidcard/159 |

Daytrading is a completely different jobset from mining. You could make a lot of money daytrading, you can also lose a lot. It has nothing to do with mining, just the same as making kernels doesn't. They all go together, but at the end of the day you don't even need those GPUs to do it. You could've sold them all and just switched to daytrading and made even more money.
-MORE OT- You got a point there but nothing to do with mining? Every miner has to sell, knowing even basics about (day)trading increases profits much more than any optimized kernel. Only miner who doesn't need trading skills is BTC bagholder who autosells everything to BTC. |
