Simplifying information into arbitrary numbers is a terrible idea imo.
Especially if you put market cap in there instead of liquidity (volume) which is way more important.
Also, the name being as important as the tech (copy paste coin or not) doesn't make much sense either.

I don't know much about Pascal but I don't think the performance gain will be anywhere close to 10x for mining.
The die size is the most important factor I think. The increase in efficiency will put even Maxwell cards at a disadvantage but to what degree, we'll see.

There used to be a spreadsheet out there that users could upload results, etc, too...
I used to maintain a few of them for scrypt (wow this is flooded) and keccak and I haven't heard of any newer. To be honest I don't see the point of starting again because everything changes rapidly. Again, as I'm used to looking at the 24h graphs at nicehash, I can tell you that the reported average can easily go up or down by 5% or more, in a 5h window. This stands to produce a potential reading variance as high as 10% overall, or more. I'd put my finger at the 12h mark for the minimum period of reliable reporting, and ideally, the full 24h time frame.
Regarding the fluctuation on pools, it's probably vardiff. It never reaches equilibrium so it always increasing the diff until your accepted share frequency gets below a threshold then it decreases the diff to offset it until your accepted share frequency goes above a threshold over and over again. And if vardiff occasionally jumps too high you might not even submit a single share before a block is solved so you're work is useless. With fixed difficulty settings you can find a setting that let's you submit shares in a steady rate. I prefer submitting a share at around every ~3 seconds to avoid missing anything. But then again if a lot of people are using too low difficulty on a big pool then they are practically ddosing the pool which is why I guess vardiff was created but I think most pool owners are using it terribly. Solomining FTW. |

H61/81 is good as they have two on board molex socket. These cards are built for mining, so they are robust.
With powered USB risers I don't use the molex sockets on the motherboard. While PCI-E 1x sockets can only output 10W, not even that is being pulled from there. The cards pull everything from the riser, therefore the PSU itself so I think it's pointless to use those sockets and those sockets are only there for the early unpowered risers but nobody uses them anymore. |

I've always wondered what are exact power consumptions bathrobehero really great idea, to look into the firmware. So then the 970/980 are not as efficient as it appears at first sight.
And for anyone else into thinking of flashing the 750Ti, unlocking the extra "power" - don't. I've done it on all my cards 14 of them (Gigabyte Windforce) and had most of them replaced. They are just not built for a higher voltage,...2 of them died just recently have to RMA. Perhaps flashing the newer generation of card is another story, but I don't advise it unless you have spare money/time to throw around. If someone is going to experiment with flashing I'm all in for undervolting - to achieve even better efficiency.
I bought 6 x GV-N75TOC-2GI cards almost exactly a year ago and 2 of them already died on me. When the first died I replaced the stock BIOS on all of them but a second one died anyway and is in the process of RMA. They both bricked completely (no fan spinning, nothing). I thought they had solid build quality with plenty of headroom because these have 36 months of warranty. I also have ASUS (GTX750TI-PH-2GD5) and MSI (N750Ti-2GD5/OC) cards, none of them have additional 6-pin connectors and all the cards have big differences in how much OC they can handle while being stable. A few of them can handle +160 Mhz with most algos while a couple of derpy ones (both MSI) crash even at around +70 Mhz. So I pushed 60W BIOSes on them as well but it didn't help much with the derpy cards so I reverted them back to stock BIOS with only disabling boost for more consistency. On another note I did a somewhat useless comparison. Useless because I can't be arsed for now to try each brand with different efficiency PSUs so I just did a quick comparison and the rig with the MSI cards is on a bronze PSU (XFX Pro Series 650W) and is pulling ~9% more from the wall than the ASUS rig does on a gold PSU (EVGA SuperNOVA 850W G2). But then again the MSI cards are 62-65°C while the ASUS are 55-59°C doing the same hashrate with same OC and very close fan speeds (+/- 10%) so it could be just the cards. If the 9% difference would be solely because of the difference in PSU efficiency (which more than likely: https://en.wikipedia.org/wiki/80_Plus#Efficiency_level_certifications) then with more investigation it might be worth it to buy really high efficiency PSUs and use 900-series cards. |

Alright, whatever I'm out of your hair good luck trying to recruit people to dump on with easily manipulated low volume markets I guess.

Gigabyte 750Ti Windforce OC on quark, stock clock, with an 80+ gold PSU, consumes exactly 60W from the wall.
I can't really play with overclocking or power target since my rig is running linux and nvidia removed the coolbits option from the linux driver. Didn't find a way to control that on linux yet.
If someone has a solution that works from the command line, PM me. I'm ready to offer 48 hours of mining (4 GTX 750 Ti) to the pool of your choice :-)
It doesn't work from the command line, but I used to have 5 750Tis. I would reboot into DOS and flash 'em with a modded BIOS. Thanks. My main reservation with this solution is I will probably have to flash them A LOT before I find optimal settings and I'm afraid the bios will just die before I'm done :-/ The offer still stands. Forget nvidia-smi, it does not work with low-end cards... You could boot up a windows, find a suitable OC which works with every algo (meaning not too high), note the frequencies and the voltage and flash a BIOS with those settings. I wonder if you can switch between power states in Linux because if so, you could potentially use different power states as different OC profiles. |

If a coins is up 66% then it really isn't likely to increase even more. Especially if a coins is barely traded. So your tips are essentially always late when a coin is already pumped and waiting to be dumped. Here's the coin now after 9 days of 0 volume and in danger of delisting:  What a bunch of false nonsense. This coin can easily skyrocket and I outline how easy it is to do here: https://bitcointalk.org/index.php?topic=1083575.msg11557908My tips are timed quite well, my wallet balance is proof of that  Rather than be another butthurt complainer, how about contributing and adding value instead? Why would I be butthurt? I don't follow anyone's advice and my contribution is to point out that people shouldn't follow other people's investment advices on coins which has virtually $0 trading volume. And that fact that your tips are always happen when a coin is already pumped and waiting to be dumped so you're essentially looking to maximize your profit by trying to convience others to buy (and increase the price even more) so you can dump on them doesn't help either. Pick a few coins with decent trade volume to prove me wrong and note the price when you announced your tip and note it a few days after. |

Nice! This is what lead me to start looking into the power consumption: A bit off topic but I picked up a GTX 970 (Gigabyte Windforce 3x) only to realise the TDP of this card is not 145W but 250W. With stock BIOS, 100% power target and +160 Mhz core OC it draws 234 watts from the wall mining groestl (which seems to be the hungriest non-scrypt algo) on a 80+ gold PSU. It seems its efficiency plateaus around 40-60% power target limit depending on algo:  That is a 68-75% decrease in efficiency depending on algo compared to stock settings which is huge! This is important when profits are barely above electricity, for example if you pay $0.14 per kwh for electricity, going with yaamp x11 payout figures (which are not very profitable) one of these cards would earn 0.00371 BTC on stock settings while it would earn 0.01652 BTC after electricity at 40% limited power target in a month. On the other hand with more profitable coins/algos like quark, it's worth it to go full speed and overclock because it would end up earning more (0.08967 BTC on stock vs. 0.13118 BTC overclocked in a month). I thought it was quite interesting. |

For the time being, it is better to buy used 7970 cards, undervolt and under clock to mine Quark. You can reduce the memory speed to very long, around 300MHz to save electricity. Quark mining does not require memory bandwidth. It is profitable for perelectricity price up to $0.2 per kWh. I do not know how long the profit will last as it depends on the price of single coin (Shark coin, SAK). If SAK price collapse, then there is no profitable mining for most people with high electricity price.
What hashrate and power consumption (preferably at the wall) do you get? |

TDP
TDP
Yes, it's not how much a card can pull but TDP does correlate fairly well to that amount (at least it did until the 900-series) and we don't have better figures from the specs. (Linus' explaination: https://www.youtube.com/watch?v=yDWO177BjZY ) I downloaded some random stock BIOSes from here and opened them in Maxwell II BIOS Tweaker to check their maximum TD.. I mean power consumption using this image to translate the figures and here are the results (in watts): Bios Flavor Maximum Target

I added two 980 (CBA to add more) to the list to show the figures does seem to be correct - at least compared to a stress test from a Tom's hardware review:  Ps: we should really have more threads instead of flooding this one with everything |

what parameters do you use for the commandline? ...
do you have spmod results? ...
tanx ...
#crysx
In case that was aimed at me I used -i 20 because higher figures like 25 used the same amount of memory and didn't increase the speed at all so I figured that was the max. I don't think sp_ added zr5 into his fork. |

Either. Both, if you can.
There you go (Tpruvot's latest release: ccminer-rel1.6.4-vc2013): 750 Ti (GV-N75TOC-2GI): stock 1.02 mh/s at 58.6W oc - 1.14 mh/s at 65.4W (+140/0 - 1293-1328mhz) 970 (GV-N970WF3OC-4GD - 250w OC edition instead of 145w): stock - 2.75 mh/s at 187W oc - 3.0 mh/s at 208W (+185/0 - 1501mhz) 780 Ti (GV-N78TOC-3GD): stock - 2.0 mh/s at 237W oc - 2.26 mh/s at 275W (+120/0 - 1204mhz) Measured at the wall and while the cards are on a 1300W 80+ gold PSU, it's barely utilized so its efficiency is probably pretty terrible. Used my go to OC settings but it could probably go higher. |

Bugreport for Neoscrypt. Running 5 970s on the same system causes it to spit out "Cuda error in func 'scanhash-neoscrypt' at line 67 : out of memory."
Limiting it to any 4 devices with -d eliminates the problem. Tried running separate instances with different devices, doesn't work. System memory is fine. DJM's miner has the same problem.
you need more memory... or pagefile... (which is required to allocate that memory to the gpu...) alternatively you can lower the intensity, that should free up some memory other alternative, try to start 1 or 2 ccminer session As mentioned running more then one instance does not fix this, system memory is fine. It doesn't get maxed out or anywhere close to it while monitoring it. I'll throw some more memory into the system and see what happens though. Currently it's at 4GB. Haven't tried a lower intensity, this seems more like a bug then anything if that's the case. Memory is not necessary, pagefile will most likely work. I have 14GB (!) of pagefile on my rigs because I think there was a cudaminer algo that only ran if I had tons of pagefile but it never used more than a few megabytes. Same goes for sgminer to a certain degree, although I was never able to run it with more than 4 cards enabled. Can I get some ZR5 (Ziftr) hashrates from people with 750Ti/960/970/980/980Ti? Power use in W, too, if you've got it.
Stock or OC? |

It's always best to do your own research with your own figures (card price, electricity, etc).

If there was a coin that could seeriously make you rich it was MINT coin.
This is my sad story: I sold all my MINT coin some months ago when there was not much activity going on with it. Nobody wanted to buy it and the price was 1 satoshi. I saw no real future for it and so I decided to sell all my MINT for 1 satoshi per coin and investmented in some other. Currently it is being traded at 16 satoshi. And if you consider the pump just a couple days ago, it reached a peak price of 39 satoshi!
1 satoshi <<<< 39 satoshi
Only if I knew.
The reason I leave all my coins in my wallets rather than making a few mBTC if a price of a coin crashes. Although the waiting only worth it like 1 in a hundred coins. But there's a difference between already owned coins and investing into dieing new coins. |

The whitepaper is promising, I give you that but keeping 10% of the total coin supply for the devs is definitely not going to fly (and then there's asking for donations).
That amount early in the coin's life with expected poor liquidity is almost a form of centralization because that amount if dumped would kill the the coin.
So people would need to trust you not to dump it and that doesn't bode well.
And I still don't get how a coin can start with PoS and be successful when there are no miners who are incentivized not to sell the coins below cost of production which creates a floor. There's no floor with PoS so their price is artificial until there's utility and high demand behind it.
I would also argue that staking is not a form of mining.

Time for another round of quick profit  QuickSilver is the place to be right now. Get in while you can. Easy 2x, 3x or more if you buy what's being offered. There is good news coming up for this coin in spite of a little previous turmoil  I think you are late with your tip once again:  How so? At ~1300 sat there is an EASY 2x, 3x or more. It's been as high as ~9K so the climb to 4K or more is not a problem for this coin If a coins is up 66% then it really isn't likely to increase even more. Especially if a coins is barely traded. So your tips are essentially always late when a coin is already pumped and waiting to be dumped. Here's the coin now after 9 days of 0 volume and in danger of delisting: |

patiently waiting for the release of the plans, and the Mac Wallet -  In a couple of hours Block rewards are really nice at the moment! Having doubts about implenting superblocks as we speak  What does the community thinks about the superblocks? Yes or no? No to superblocks. Superblocks I think are only good if pool mining is impossible. With pool mining the superblocks would just increase the average blockreward by a calculable percentage because every block is being shared by most miners so the variance behind superblocks would be negated. In case if poolmining would be impossible then superblocks would be truly distributed to 1 lucky person per superblock. |
