Not trying to talk smack sp_ but i run 4 x 980ti... and really have never seen any BIG improvements in hashrates. Dont get me wrong i love ur work. but constantly asking for moonies and saying something is a whatever increase and no one really ever seeing it? Kinda bullshit if you ask me.
How much is a BIG improvement? |

Testing my new wattmeter, trying to break 1000W barrier with mining quark...
.74 ~87500 MHASH
.76 ~89300 MHASH
No difference in power consumption between these builds. 970-990 Watts with insane power settings. 5 x 970 + 4690K OC + 4 x 4GB, not a pure mining rig.
Oh, and my 0.05226518 BTC should arrive soon!
-edit-
standard clocks and power limit:
.74 ~76600MHASH
.76 ~79500MHASH
860-880 Watts

where we can find the miner for 280x (4Mhs) share a link please
Wolf0 (wink, wink) does not share links. |

sp-mod@GTX970 default clocks, 4.3MH/s...

Last night my 3 cards mining spread got ~ 100coins, I saw these in the morning showing in the wallet, and then suddenly they all became "rejected" ?!
Any idea?!
Are there newer wallet/miners :S
No, most people are still mining with the GPU miners created by Mr. Spread / girino and tsiv. Can you provide us with a getinfo of the wallet you used for mining? BTW mining 100 coins with 3 cards in 1 day seems unbelievable... what's going on here? Could it be that you started the wallet in testnet mode? Every day about 8000 SPR are mined. Right now nethash is around 300MH/s so you need about 3.75MH/s to get 100 coins a day. That is about 2-3 GTX750ti or one GTX970. |

yes, all of my gigabyte windforce models have the power-limiter mod to 64 watts instead of 38.
@antantti, yes two of the gigabyte cards are in my daily win 10: 32 bit machine, running release 66 of ccminer. the rest are running under kopiemtu (Lubuntu 14.10 - 64 bit) USB install.
Ok, you running 32-bit operating system. There must be a good reason for that? |

getting coolbits to work on linux does require some legwork but it does work headless at least on driver version 346.59 + Cuda 6.5
I just ran 2x Gigabyte WF GTX 750ti cards to their max on lyra2v2. I can't get much past 1358 MHZ core clock and +100 MHz mem clock without them crashing on Win 10: 32 bit, Release 66. Best I could do was 4900 kH/s. Once I start actively using the computer, the card that displays on the monitor crashes.
If you want to clock higher you need to modify the tdp in the bios from 38W to 63W. And you probobly need powered risers/or cards with a 6pin power / or motherboards with extra power. I had one ETH mining rig with 3x750ti. With ubuntu 14.04, cuda 7.0 or 7.5 and 35?. drivers overclocking was easily done. Genoil cudaminer thread where I found all the info I needed. Hashbrown, you have 32-bit W10? Or 32-bit ccminer? |

Keep rebooting windows, at some point it usually finds all cards. If it sees 960 it should find 750 too.
Are you sure your pcie settings in bios are what they should be? Usually you need to do some tweaking there when running more than two GPU.
Which leads to my question... someone here running skylake (Z170) based mining rig with more than two nvidia cards? How did you do it? Spent 12 hours last night trying to figure it out...

The main benefit of the BTC MBs is the ability to supply 75W to 1x slots which are normallly limited to 15-25W, which makes
the use of unpowered risers possible.
All the motherboards can provide 75W thru the 1x slots, it's by specifications. The rest of the pins do not provide any power. The difference is that the BTC MB can provide 75W to ALL the slots together. I wouldn't ever pull 75w through the tiny little traces on a motherboard to all the slots at the same time, that's just a recipe for disaster, regardless of having a extra molex connector or two supplying juice. Everyone can easily test it. Do some search with melted ATX-connector, when mining touch the connector somewhere near those two pins. |

I have tested some more. Release 74 is using more power and heat, so the card trottle and performance is lost.
My test was conducted in a closed case rig with a EVGA superclocked card (2x 6pins power)
but my dev card:
The gigabyte 970oc G1 comes with 1x8 pin and 1x6 pin and doesn't trottle and give bether performance in release 74 than 66.
SP_, all 5.2 maxwells do at least 1500MHz under load. In open case, limiting factor is TDP. Nothing to do with power pins. -edit Testing how far I can go with reference 970. You need to give this baby almost +300 to get there (1500). Around 10500 kH/s mining lyra2v2. -edit2 Same settings with quark, hitting TDP and only hashing about 17200 kH/s. TDP mod is all you need if you want to get all out of these. Yeah right...  I have 6 maxwells 5.2 + 3x 750ti and only 1 of them is able to do a stable 1500+. All of them are over 1400 but no way to do a stable 1500 without a vcore rise. Each of them was slowly overclocked by 20Mhz step. When I have noticed any crash of a miner I put it 20Mhz back. Gigabyte G1 970 was also benchmarked in some Windows "gaming" benchmarks. Those are the clocks I'm using 24/7 without any stability problem and temperatures from 65-74°C: gigabyte G1 980 1450Mhz gigabyte G1 970 1560Mhz 3x Asus strix dc2oc 970 1440/1450/1480 Mhz 960 1411 Mhz 3x 750ti 1400/1420/1440 Mhz Btw I don't care optimizing H/W ratio, because the electricity price is still low at my location. With the r.74 I get more or less the same speeds as in r.66. Yeah I was wrong there when I said all maxwells... Do you have a quality PSU? Custom fan settings? I like to run my rig(s) with overkill PSUs with loads somewhere in 50-60% area if possible. Mining cave  temperature is some in 22-24 celsius area. All 5.0 I have tried have done 1400 easily, all 5.2 cards 1500, with or without power pins, with or without custom cooling. Maybe I have been just lucky... I also tested one non-reference 970 card with quark. Both cards with one 8-pin connector, overclocking both to 1500 area. Hitting TDP so hard... Non-ref wins hands down 18200 - 17200. |

Come on girls, get back to your own threads.

My poor superclocked 950 can barely get 5400 KH while my overclocked 750 TI can get north of 5200 KH using much less power- is there any more data I can give you to help with dialing in the 950? Intensity for both seems to top out at 20.
There is nothing wrong with your 950 or your config. All 9-series maxwell gpus are poor in lyra2v2 performance compared to 7-series maxwell hash/w wise. 950/60 really suck because of their crippled 128-bit memory lane. Better mine some other algo with them. |

Boost only mining eth for me. From something around 78MH to 87MH.
BTW not talking about memory OC, just reaching max original boost clocks.
Are you saying you are mining ETH@87MH? Windows? Yes, with 4 gpus. 3x970+1x980 making 719W at the wall. All cores overclocked and memory of all gpus at 7000MHz. I'm not tottally offtopic because I'm using the sp-mod version of the genoil's miner  The same rig makes 76MH in quark algo, consuming 840-850W. Aah ok then... good luck with fighting with those amd guys... |

Nice. I will soon submit a 5% increase in the lyrav2 algo.. improved quark and x11. VTCbeer coming, ec101e1a76caff7e88cbd09a1c5f46f375433fd0c82eb5c2ba8701cb7363083e |
