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" 

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 ?

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.

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)

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.

Hi all.

Trying to compile cudaminer on linux.
I'm on a final error telling this :
<<

If I look at the folders structure :

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 ?

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 ;-)

I I want this version, I have to build it ?

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.
