Is palit gtx 750ti stormx oc a good card ?

Yes, it is. Very good:

I see Darkcoin is shooting through the roof right now...

Just under $1 right now....

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.

Im also getting around 600kh less with the new build from git.

750ti, cuda 6 installed. Arch linux

Is there any flags i should pass when compiling?

./autogen
./configure  ?
make

Cheers

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.

For GroestlCoin running two instances.
First for msi 660ti with new cuda_groestlcoin.cu get  5040 KH/s (OC Afterburner +10 mem)
Second for 2x msi 750ti with old cuda_groestlcoin.cu get 6500 KH/s (OC Afterburner +135 mem)

The cards are Gigabyte 750Ti 2GB. Same driver version as you.

any idea how to decrese reject shares on 750Ti?
I'm trying clevermining multipool, and my 750Ti get 300KH/s but over 30% rejected shares

changing pool... (increasing the difficulty if possible, if their difficulty is too low, you will get many rejected)

GREAT. We love it! I send you 10 litecoins.

Second for 2x msi 750ti with old cuda_groestlcoin.cu get 6500 KH/s (OC Afterburner +135 mem)

okay, the consensus seems to be that my optimization only works for Compute 3.0 and 3.5 devices.

but AizenSou get profit on gtx780 6mh/s -> 8mh/s
and not work for GTX580 down from 6Mhs -> 2.5Mhs

I guess optimization also work on 3.5 devices but not for 5.0 and 2.x devices.

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.

okay, the faster version of cuda_groestlcoin.cu is in the repo.

You should see some notable speed-up on Compute 3.0 devices. Not sure about 2.0 and 3.5 - test yourselves.

My rig with 3 ASUS MARS (6 x GTX 760 cores) is doing 24.5 MHash/s Groestlcoin with this code.

In comparison the 3x 780Ti rig is doing 38 MHash/s with some yet unpublished code (this unpublished "killer groestl" code currently only benefits Compute 3.5 and 5.0 devices...).

And when will this "unpublished "killer groestl" code" be released?
tnx

[bigjme]

Christian has said it will be around the end of the month

you will support x13 as marucoin ?

Thank you

[DemosMirak]

Thank you

X11 is still in the works, for as far as I know. Perhaps X13 will be after that, I don't know how big of a step it is.

Guys, I m noooob miner,  I was wondering if I mine (cudaminer)  with 2 PC on a 3rd PC's wallet  (all pc on same lan ) the hashrate is going to be what excepted  pc 1 hashrate + pc2 hashrate or I m missunderstand something ? Do I need 2 wallets? 

Thanks

I'm guessing you're talking about solo mining, in which case you use the LAN IP adress and such for the set-up, instead of local-host, as far as I know. As for two wallets, one for each, that is recomended, because if the computer with the wallet goes down for any reason, you can't mine. A wallet for each rig would be more redundant and reliable, and you could just wire the cash to the central wallet when you feel like it. For external acces to the rig without having to put a screen and K&B on it, use programs like teamviewer.
