Seems I have a lot of coin profitability calculations to do that I missed out on. MNR, BitQuark, JackpotCoin? Anything else I miss guys or are some of these already as good as dead? Thanks. Will release my calculation charts when done.

Lowering the price to $120 each.
If you buy them all...
Will throw in free PCI-E 1x to 16x extenders.
Will throw in free shipping or local delivery in SF bay area.
PM me if interested.

Motherboard died and unfortunately I need the cash at this point in time. Wish I didn't have to part with things.
Don't think I am interested, but it might draw a little interest if people knew at the least the make and model of the cards you are trying to sell. That was the first thing I thought of. Good luck, I wish I had the cash right now to consider it, because that seems like a good price if they are good cards. Thanks. 8x Zotac 750 Ti's. They are great little cards. Love them. Nice and quiet, stable and powerful. |

Whats the reason for selling?

Maybe not the best place to ask this, but if anyone is interested in buying 8x 750 Ti's for cheap. Willing to sell the lot for $1000 or best offer. Please PM me. Can throw in some risers for free too.

Depending on the algorithm I was mining I used different clock mhz because higher didn't always yield more kh/s.
+135-170 mhz core
+500-650 mhz mem
Scrypt ~280-290kh/s
Scrypt-Jane N-14 (Yacoin) ~3.3-3.5kh/s
Scrypt-Jane N-11 (Cach) ~480kh/s
Scrypt-N (Vert) ~145kh/s
HVC 10500kh/s
Fugue 94000-97000kh/s
Groestl 3150kh/s
Beyond just hashrates, different algorithms had different energy consumptions levels too. Scrypt being the highest consumption offender for lowest payout.
Yac is great. 8x cards on two machines only pulled 600w from the wall. Fug = 505w, Scrypt and ScryptN = 700w.

Hi all,
I am selling my 8x Zotac GTX 750 Ti's for $130 each.
$130x8=$1040. If you buy it all I'll sell it to you at $1000 and throw in a bunch of PCI-E risers.
Local pickup available in SF Bay Area.
These are fantastic cards. Extremely low energy consumption, low heat, low noise, great hashrate for altcoins like Yac, Groestl, HVC, Myraid, etc. I would not recommend mining scrypt since scrypt coins pay like crap, but everything else is easy peezy money in the bank.

Thanks bigjme. Is this Compute 3.5? I tried using your compile with my same old groestl bat file. The performance was worse. From 3100+ kh/s down to ~2450kh/s. You experiencing any difference? |
|
|

Yep. Thats why it would be great to get it released soon  Hehe, I hope Christian is mining it out in the meantime. He deserves it. |

My groestl on my 750Ti's are 3.5MH/s per card
And i always take into account power usage. £0.67 a day at the moment
The current ccminer development version does around 25 MHash/s for groestlcoin on 3 750 Ti cards. EVGA FTW edition, no overclock beyond factory clocks due to running Linux. With a bit of OC, that would be 9 MHash/s per card. With those hashrates, it would make groestl the highest paying coin of the coins I track as of currently. |

Hi guys,
What is the new halving schedule supposed to be like? Thanks.
|

Its working for me aswell. Certain sites wont load for me either but will load through my phone How do I know which compute version 750Ti's are? Thanks.
Compute 3.5 as nomad1109 linked, 750 and 750Ti's are actually compute 5.0 We simply run them under compute 3.5 normally in the miners Thanks. Are you seeing noticeable differences between running sources vs 2-28 version? |

Overclocked +135 core + 600 mem with increased TDP bios Cudaminer 2/28 = 3.35kh/s on Yacoin!  cudaminer.exe --algo=scrypt-jane -H 2 -L 2 -i 0 -l t64x1 -b 4096 -m 1 Using the exact same settings I only get around 2.4kh/s. Any idea why? Which card exactly are you using and which driver version? I am still on 335.23. Also, I am no longer using any increased TDP bios as it doesn't really help. My overclocks nowadays are dependent on which of my cards exactly. Some of them I can push to +170 core +650 mem. I have been getting around 3.3-3.5kh/s on YAC these days with the occasional dip down to ~2.5kh/s. |

Is it possible to know the detail behind those calculation? I would like to build a small table like this one. Thanks!  It is a massive Excel sheet with tons of cross referenced calculations taking into consideration all factors I could think of ranging from difficulty adjustment schedules, measured hashrates, varying energy costs relative to my specific conditions, varying exchange rates and differing pool and exchange fees. |

Aslong as i can keep my income higher then my costs i am fine with that
I've done some work on the table based Groestl (the SPH library based version), which would benefit CCMiner 0.5 neatly. Maybe I can commit that part separately. Christian Awesome! Thanks for all your hard work. I will update my profit calculations after I measure the new hashrates and power consumptions. |

Ask and you shall receive.  As always, this is with 8 750 Ti's with an occasional 9th assist. If groestl gets way more hashes expect it to be one of the higher paying coins. Do you mine everything basically 'solo'? or is this just the way that you calculate. I have never tried solo mining... but it would be so nice to not have to really deal with all the pools. I have 6x 750ti up and running as of last night, so would you think that these numbers would be straight conversions (as estimates) of performance? Or is there some level in solo mining where you will never get your own block done? Thanks for any input, I always find your charts useful. To clarify, I don't usually mine solo. That is just a theoretical solo mine time needed to receive 1 block based on current difficulty. I have it there just to see if it might be better to gamble on solo mining and avoid pool fees. In the past I've switched to solo mining Fugue a few times because the block times were so low for me to find a block by myself. So in a nut shell, no real need to solo mine. |

sooo, who's up for doing some profit calculations for us? groestl is now no longer profitable after the huge amount of people that jumped onto it when the price shot up. right now with 3 750Ti's, and a power usage of only 155W for the entire system, daily profit is £0.08 or $0.12 sooo, profit calcs anyone? Ask and you shall receive. As always, this is with 8 750 Ti's with an occasional 9th assist. If groestl gets way more hashes expect it to be one of the higher paying coins. |
