Good ;-) I'll send when I have some. I'm in coins for only two months, and this trip leads me to go back with C/C++ after 13 years in JavaLand (doh! what I've done?). Cuda apis seem nice, makes my return to C++, doin it "the hard way" ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

Hello all.
6x MSI TF 750ti mining at 13,000 KH/S with OC 150 for GPU & RAM in one instance of CC, windows 8.1.
Thanks a lot Christian(s) for that, I really wanted to mine some Dark for long. Was beginning to feel depressive with heavycoin and groestl since standard scrypt clones may be reserved to hardware specific miners soon.
Danke sehr meine Herren!
ps : not in the mood for parsing this big thread, have any dark address we could send to ?

About ccminer. I just jumped into Groestl with 750tis.
- ccminer unoff package version 0.6 gives me about 2.5/2.6 MHS - ccminer 0.5 using ccminer35 gives about 3.2/3.3 MHS
Thanks to all for your work. I'll try to have a functionnal compile station to try help a bit too.
I have posted 2 compiled versions. One for 750 and one for 600 to 780 Which did you get? First posted, I don't find the original post. edit, some extra-infos : Usual scrypt mining is 420 watts at the wall. Groestl mining is 230 watts at the wall. (6x 750 ti with stock voltage) How are you managing 6x 750Ti's on 230W? My 3 are pulling 133W, on their own psu I don`t know how you manage to mine at that watts, at scrypt (stock voltage - overclocked gpu to 1280mhz and mem to 3150mhz) my 6x750ti rig pulls at the wall 520w and on myrad with one ccminer window 260, and with 2 ccminer windows pulls 290w - here mem is 2600mhz. Re all. Not here to talk about rig design but anyway : KillAWatt says 460 for 6 cards mining dogecoin for example. With 6x on Groestl is more about 260 (not 230 like I said). Asrock H81 // 6x MSI 750ti twinfrozer on powered risers // 1x small SSD // PSU Corsair 750 gold // some wood :-) // overclock GPU+150 & RAM+150 edit : with always 1 instance of cudaminer or ccminer running. I avoid except if something goes wrong.

Hi all.
Trying to compile cudaminer on linux. I'm on a final error telling this : << ptxas info : Used 30 registers, 336 bytes cmem[0] g++ -g -O2 -pthread -L/usr/local/cuda/lib64 -o cudaminer cudaminer-cpu-miner.o cudaminer-util.o wrapnvml.o cudaminer-sha2.o cudaminer-scrypt.o cudaminer-maxcoin.o cudaminer-blakecoin.o cudaminer-sha3.o cudaminer-scrypt-jane.o salsa_kernel.o sha256.o keccak.o blake.o cudaminer-blake.o fermi_kernel.o kepler_kernel.o test_kernel.o nv_kernel.o nv_kernel2.o titan_kernel.o -L/usr/lib/x86_64-linux-gnu -lcurl compat/jansson/libjansson.a -lpthread -lcudart -fopenmp -lcrypto -lssl -ldl -lcrypto -lssl /usr/local/cuda/lib64/libcudart.so: file not recognized: File truncated collect2: error: ld returned 1 exit status make[2]: *** [cudaminer] Error 1 make[2]: Leaving directory `/home/admuser/CudaMiner-master' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/admuser/CudaMiner-master' make: *** [all] Error 2 >>
If I look at the folders structure : << lrwxrwxrwx 1 root root 16 avril 21 10:18 libcudart.so -> libcudart.so.5.5 lrwxrwxrwx 1 root root 19 avril 21 10:18 libcudart.so.5.5 -> libcudart.so.5.5.22 -rwxr-xr-x 1 root root 0 avril 21 10:18 libcudart.so.5.5.22 >> The file " libcudart.so.5.5.22" (that is the ending points of file links if I'm correct) has a zero length.
Any idea ?

I I want this version, I have to build it ?
It would be better... (you would also get the newest improvement to cpu usage and multi gpu support which were added to the github yesterday evening). Nevertheless, I posted a link, for testing purpose, to the binary few page ago but you will certainly need some dll: http://www36.zippyshare.com/v/12355342/file.html. (you can find them in some old cudaminer release). It doesn't include the latest improvement and it is for testing only. Thanks a lot. I'll join the adventure to learn how to build cudaminer (C is not my everyday language). If I fail, I'll rely on your build ;-)

Hi, // excuse bad english
If it helps : - 6x MSI GTX750ti is 420watts at the wall - never seen my PSUs fan turning... (Corsair 750gold) So even with 6 cards I have a LOT extrapower in reserve.
BTW here to ask for something about Cudaminer & Vertcoin.
Has anyone succeded to use CBUCHNER1 stock cudaminer (taken from Github last version) to mine VRT ?
1/ I've seen that a custom cudaminer is available on vertcoins site. -> tryed this and it gives me 95khs when I get 290khs for any scrypt alt (so i should get about 140, and 100 instead of 140 is a big loss). -l T5x24 & some other confs give the same result.
2/ Tryed lot of conf with official cudaminer release (x86 & x64) and it seems not to work, best result was 20khs.
Missed something ? edit : note that rig is stable, no OC or heat or power issue

Hi all,
Well, let me report my experience with this motherbord. Doin lot of tests with it for the last 10 days.
// excuse my bad english...
Setup : - PSU corsair 750gold - 5 GPU nvidia GTX 750Ti (for information, each caped at 55/60w at full load) - running Windows 8.1 - my first rig
- with non-powered pcirisers : 3 GTX750ti max - Non-powered pcirisers + extra molex pluged on MB : 4 GTX750ti cards max
And that's all...
So, i decided to investigate, seems like power was the issue. Bought some powered pcirisers, made some tests...
Conclusion for me with GTX750Ti cards (that only consume 60w each, wich is very low compared to AMD Rx2x0 cards) : Plug every cards with powered pcirisers...
Note : good tech to diagnose things if you have some doubt on your setup : launch one miner per GPU BUT not at the same time : - launch GPU1 and wait until it mines at full load - launch GPU2 and wait until it mines at full load - .... until 6th card So you'll know if you have some power issues. You should spare some efforts and money by buying powered risers from the beginning...
So : don't rely on the power that is suposed to come from MB's PCI slots.
