mine are at 1350(stock) 1450(+200) and only 235h per card...
using this https://github.com/tsiv/ccminer-cryptonight

linux seems to be faster...
OC cards make about 280-290khash/s here.
nonOC 240-250khash/s

Running on linux, and I get 230H/s @1350Mhz core/stock memory 750 ti.
But I have a low end CPU (cheap haswell @50$) , that probably the point ?

model name : Intel(R) Celeron(R) CPU G1820 @ 2.70GHz

Highly doubt that your CPU is holding you back. I'd say it's the memory clock you need to worry about.

750Ti @ 1300/1500 gives ~ 270

Palit DualX (1300/1500 stock) makes 270 using
-l 8x40 switch

still 235, are you using beta drivers? i'm at 337.88

8x60 seems to give the best hash rates on a 750 Ti. If you're on Windows you're also slightly limited by the default bfactor 6, you could try lowering it and the default bsleep of 100 microseconds but your interactivity will take a hit.

My rig has 6x Palit GeForce GTX 750 Ti StormX Dual, each hitting about 280 H/s at the default factory overclock using 8x60. The piece of shit Asus 750 Ti DC2OCwhatever on my win machine does like 244. Marvelous piece of engineering by Asus, take 6 GHz memory chips and fuck something up that they can't run beyond 5.4 GHz.

tsiv, you may want to pull my keccak implementation - getting a lot of reports it works better on Kepler.

da70729, fd9d114 and f26efdb, right? Pulled them into my local repo, building right now and will push to my git repo if everything seems fine. As far as I can tell, the last commit doesn't really do anything useful though. Apparently __CUDA_ARCH__ is only defined when nvcc (or cudafe++, whatever) is processing device code and the define (like pretty much every single arch based define in ccminer) is in the host code, meaning you'll always hit the else branch on #if __CUDA_ARCH__ >= something. I might be wrong on this, haven't had the time to see what actually goes in the final product but on the other hand I've never seen any improvement on these compute based specific macros either which kind of supports the fact that they tend to default to the "ah well, we'll use the crappy default thingy then" branch.

i've added chaincoin to cudamining.cc, was pretty easy Grin

forked from djm x17, my personal version use accepted and rejected instead of yay and boo, i like them more lol

amph i tried chain coin that you compiled and it just open then closes instantly. heres my command file. ccminer.exe -a chain thats it. do i need any more commands? thanks

EDIT: i have it, I missed the c11 Embarrassed

Tried different pool? Cheesy

Maybe something with initial diff of shares?!

Which one do you recommend?

From time to time I also get a lot's "(Share is above target)" rejects Sad

amd or nvidia ?

Hashharder Huh

Mainly AMD Cat 14.6 Beta, but happens sometimes with nvidia-331 too.

@djm34 Are the improvements from uray also possible for ccMiner and SPH-SGMiner? Can't compile his SGMiner.

8x60 is better yes i'm getting 240 now or slightly more, for bfactor and bsleep how much i can lower them?

is nvidia like amd with hynix and elpidia? could explain why some card are better than others

p.s. tried 6 and 66 only 5h more 245h per card

Props to Amph for the chaincoin algo
Also big thanks to cayars for the unified efforts with ccminer
We can also chat around we nvidia mining fans at freenode irc server in the #ccminer channel
