How much hash does a 750Ti get on Lyra2REv2?
I get between 5000 and 5500 depending on the card and overclock Huh, I only get about 4.6 Mhs with about +100 Mhz. Test machine agrees with you, running sp_'s git. Lyra2v2 GTX750Ti +185/+185 [2015-12-02 12:00:21] Stratum difficulty set to 4 [2015-12-02 12:00:25] accepted: 41/41 (100.00%), 5176 kH/s (yes!!!) [2015-12-02 12:00:27] accepted: 42/42 (100.00%), 5175 kH/s (yes!!!) [2015-12-02 12:00:31] accepted: 43/43 (100.00%), 5175 kH/s (yes!!!) [2015-12-02 12:00:51] accepted: 44/44 (100.00%), 5175 kH/s (yes!!!) [2015-12-02 12:01:08] accepted: 45/45 (100.00%), 5175 kH/s (yes!!!) The sp-modded lyra2v2 on the 750ti is almost as fast as the DJM34 opensource kernal on the 960. No LinuxMy code will almost turn your 750ti into a gtx 960. I haven't submitted anything to github in almost 2 weeks now. I am taking a break. |

Can you add the etherum algo please.
The net HASHRATE is 400GHASH

NVIDIA sp-mod(open source):
quark: 980ti (23MHASH)
980 (19MHASH)
970 (15.5MHASH)
960 (10MHASH)
750ti (6MHASH)
A Fury X mining quark with the opensource kernal will be slower than a 7950 with the wolf0 kernal.. and 3x slower than the NVIDIA 980ti
The performance between 980ti and 970 is 23/15.5=1.48. The processor difference is 2816/1664=1.69 The performance between 980 and 970 is 19/15.5=1.22. The processor difference is 2048/1664=1.23 Why 980Ti is less efficient per core? Is that limited by power? ccminer Sp-mod release 74 is doing 26.5 MHASH on the standard clocked gigabyte windforce G1 980ti (8pin+8pin power) 20 MHASH on the standard clocked zotac amph 980 (8pin+6pin power) 17.5 MHASH on the standard clocked gigabyte windforce G1 970 (8pin+6pin power) 10.7MHASH on the standard clocked asus swix 960 (6pin power) 8.5MHASH on the standard clockes EVGA SCC 950 (6pin power) 6.25MHASH on the standard clocked asus swix 750ti (no external power) 5.1MHASH on the standard clocked 1gb gigbyte 750 (no external power) |

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 sold a couple of r9 280x and I picked up a cheap r9 nano. I wonder if the 4096 shaders@175w can be used for mining.  cheers I did some tests and found it behaves pretty much like Hawaii, maybe a bit less power usage.But a new driver just came out so the tests need to be done again, as the new driver may include an updated compiler (which is not uncommon when a new chip is out). Maybe someone tested the new driver already? I got it new for $500 with free shipping(black friday sale). Will probobly never ROI, but I need some more challenges. Furyx users renamed wolf0's hawaii bins and upgraded to the latest driver to get a boost. (x11) |

What clocks would you recommend for 750 ti and a 980? I thought I remember someone here saying that memory clocks didn't make that much of a difference. Thanks.
You need to find out yourself. But I can give you a hint. The lyra2v2 can do 5.2MHASH@750ti with the sp-mod opensource kernal. But it won't do it with a gpu core of 1500MHASH, and intensity to the max. To mine with a profit you need to know your cards well. Changing the sourcecode in the kernals is not enough. The opensource kernals kan perform 15-20% bether with a right config and overclocks. |

would luv to another update with a nice kick upwards in hashrate for some of the algos - hint hint sp ... ... #crysx Right now it's much more profitable to work on private kernals #crysx. The memory algos are heavily dependent on the right clock settings / boost / voltage etc. I have modded the lyra2v2 to run faster on one card, but slower other other cards. I think I need to review the opensource kernal and pick the fastest routine for all cards. Maybe make seperate kernals for each of the maxwell gpu models because they are different. o ok ... but you are not selling the private kernels are you sp? ... i guess a more unified approach would be better ... separate the kernels and add them into the miner on a modular basis ... tanx ... #crysx Difficult to sell kernals that run fast on one hardware and slow on another. Then you need the same operating system and the same cards that I use. The Pallas Neoscrypt kernal is 10% faster on some cards, but when you see the test performed by the cryptomining blog, his work doesn't have any effect. |

The Lyra2v2 timings are depended on a good coreclock/memclock and boostclock (no trottle'ing) The problem is when I mod a kernal to run fast on the 960, it might hurt the 970 performance. When I mod a kernal to use more power, cards with little power will start to trottle. The cryptomining blog has compared the 20 last sp-mod versions on the gtx 970:  Pallas Neoscrypt kernal was merged into release 59, but as you can see in the table above the hashrate is down.. This is not correct for many cards. I verified that my gigabyte g1 970 was up 10% And the hashrate was around 580KH/s (Release 66 does gives 550KH/s) wich is closer to what I am getting. |

what speed (x11 algo) will a 750ti hash at with the latest release?
X11 hashrate-- Release dot 74 should hash at 3.1MH/s or better on a 750ti. This depends on the model, overclocking, etc. My EVGA 750ti SC (no 6-pin connector, single fan) gets 3.1 MH/s on Linux with no overclocking. --scryptr the gigabyte 750ti oc lp cards ( in thefarm - no aux power connector ) do on average 2800KH with x11 - stock on fedora 22 x64 cuda 7.5 ... #crysx Cuda 7.5 x86 build is doing 1.9 MHASH(750ti). And the 64bit build is around 10-15% slower than the x86 cuda 6.5 build. can i safely assume this is windows sp? ... the linux compiles are running better than the cuda6.5 compiles that i was building prior to the fedora 22 x64 upgrade ... and being x64 native - maybe that has something to do with it ... i dont use anything x86 - unless they only come in i686 format on linux ... and there is no other option ( which is quite rare in linux ) ... #crysx This is windows. And with abit of overclocking you should be able to do 3,4MHASH stable. This is 600KHASH more than your linux setup. 22% faster. If you move to windows your farm can produce 22% more coins. |

Some quick Quark testing. Cards overclocked 180Mhz  1 year ago quark was doing 14MHASH with heavy overclocking. so you got a 50% free boost with the SP-MOD |

I can see it in the link. I don't have a compute 3.5 card. Maybe there are some possible speedups to be made on the 780ti. Anyone with a 780ti card who can compile the latest version (add compute 3.5 in the projectfile (or makefile) What hashrates are you getting? EVGA 780ti SC +100 GPU OC Quark: 11.7 MH/s X11: 6.35 MH/s Lyra2v2: 7.7 MH/s Neo: 330 KH/s (375 with r58) But release 74 doesn't give a boost comparing to the old ccminer on compute 3.5. Most of the optimalizations are Maxwell only.. |

With my 6XEVGA 750 ti SC (No Bios mod, no extra connector, no OC, Max 1320MHz) on LyraREv2 it is 395W In from wall on digital PSU. Windows 8.1 Pro
Quark 420W in from wall
Idle 90W in from wall
Lyra2v2 on the 750ti should do around 5MHASH each with the correct clocks. so your rig does around 30MHASH if you tune it correctly. The 980ti only does around 18 MHASH with overclocking and costs the same as 6 used ti's. But the 980ti can ofcourse do much bether with the right code.. |

I got two Inno3d 980 cards delivered today:  Running on R74, but not that happy about the perfomance. Both cards are overclocked with 220Mhz  I am returning these and will switch them for 3x Asus Strix 970 cards instead. The info could maybe be usefull for someone. I think some of the kernals need some more tuning on the 950, 960, 980 and the 980ti. I have a few cards, but not enough to make it worth it.. Is that 375W for the whole rig? The cpu, harddrive and motherboard can draw 75W alone. Then you have 150W per card wich is pretty good. An AMD 280x@4.2 MHASH use 200W |

I just want to poke my head in here to say thanks to SP. I've been converting everything I own from AMD to nVidia Maxwell and comparing SP-Mod to tpruvot.
SP-Mod rocks!
Donation sent. Buy yourself a 6 pack of your favorite beer.

maybe I called it -x don't remember.. Run ccminer --help
the readme hasn't been updated in a while...
ccMiner release 1.5.2-tpruvot (SP_MOD) (april 2015)
