I just set-up a 750TI in my home computer, next to my 760. Is it possible to use separate launch configs? I thought it was like "-l K6x32, T5x24" but that doesn't work Can anyone help me?

EDIT: Found it! Just had to delete the space So it should be: "-l K6x32,T5x24"

Superb! I really want a 750ti

The random 0% GPU load I was talking about only happens with cudaminer, not any other miner. The coin switch (and associated 0% gpu load) happens for both, of course.

Thanks tachyon_john, this is exactly my problem. So if it happens with Wafflepool, Tompool and Blackcoinpool, it might be some issue in the cudaminer code too

I'm trying out my luck at multipools, but I've run into a small problem: Sometimes, at random, the GPU drops to 0% usage. I can't find any particular reason for this, it isn't a switch to another coin or something the like. It happens with Tompool and on the beta Blackcoinpool. Does anyone run into the same problems as me?
Doesn't happen with AMD at that same moment BTW, the coin switch does.

USB3.0 cables are SFTP... So I guess you're much better off with USB3.0 risers than those simple ribbon ones.

I'm using this for my bat for my gtx760.


It kills the cudaminer process after an hour, and restarts the loop. I was getting many different errors with some stratums after 2 hours or so, no problems ever since I've been using this loop.

Well, it was more profitable than my GTX760 when it was just CPU-only. I had to set -H 2, but the 10% drop of my GPU was compensated with a 25% boost for my CPU. But it's not profitable anymore, so -H 1 is back on and no CPU miner.

Yeah, such protocol extensions need to be implemented by both miner and stratum. A chicken/egg story. But if cudaminer would have it, many multipools would be eager to implement it themselves.

I was wondering, is there room for a stratum extension which will allow switching the algorithm, stratum-side?
There are some new interesting multipools, like BCmultipool.com, and they're gonna include Scrypt-Jane and Keccak next to classic Scrypt. It would be nice to know if a miner could hop onto a keccak coin when that's most profitable, and jump right back to Scrypt when profit there goes up.

Could be coded in next to a failover-strategy

Loving the idea! Can't wait for more stats after the beta ended
And what about keccak? Maxcoin, Helixcoin and others have a much higher profitability, but either too hard to find a block or too new to the game But I love how my GPU runs at max usage and only at 55°C

EDIT: Just read the FAQ, and you're planning on it Great!

Yep! VS2010 SP1 did the trick Thanks a lot bcmog!
BTW, your first post here You just registered to help me out, how sweet   

@bigjme: Building.zip doesn't download :s Stops after a minute or two.. But I guess that wasn't the problem. Thanks for helping

In debug, it gives me the same error
Yep, I can't find any dll's in the curl folder, though I downloaded them from the first post :s Is there a way to get them elsewhere?

EDIT: Oh, you're on it Thx!

Not that much interesting, I guess but still: http://pastebin.com/Gt4DTeiS

@Bigjme: I was already testing it at Release, but with x64. Win32 gives me the same result.

WHoah, thanks for the tips guys I managed to get a step further by placing it in the directory above as sambiohazard and bigjme proposed
But I get an error at linking: 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
So I'm almost there, would be fun to be on top of the source Any thoughts on that last error?

I'm trying to get CUDAminer compiled, and since I don't have much programming experience, did some C# & Java a few years ago, I'm failing miserably.
I got the source trough TortoiseSVN, installed CUDA toolkit (is their GPU driver mandatory? cause there are much newer drivers available) and opened the .sln in Visual Studio. I copied the content of the Visual Studio prerequisites zip file to the /trunk folder. But whenever I want to compile it, it's complaining about pththreads.h not being available. When I hardcode the <include> to the right path, it gives an error on the next header file of those prerequisites.
Any way to make this easier so I don't have to copypaste every path?  

I've been following cudaminer since I got into mining 2 weeks ago. I've only got one gtx760, because before I was a normal gamer.
I started this late because everyone kept telling me that Nvidia cards aren't worth it. But now I'm getting 333kh/s scrypt and 110mh/s keccak =)
Currently putting all its power at keccak, cause it makes my card run much cooler; 53°C instead of 65°C with scrypt, at only 50% power instead of 85% And made a humble 0.02BTC, which is not paying the electricity yet. But I still live with my parents, and compared to the 2 fridges, freezer, many lights continuously sucking electricity, many other computers... they won't notice the 200W (150W keccak) extra

But I can't wait for the HVC miner, as I was into it since the pre-ann, but with my poor i5-3470, I'm only getting 150kh/s, combined with 2 laptops, this gets up to 200kh/s but at much more power ofcourse.
Does the card run hot or cool with your implementation, cbuchner? Just curious

I did experience this multiple times when overclocking my card. I was surprised because I'm using the onboard GPU while mining, but my system kept on freezing completely when I added another 200mHz core clock to my gtx760, 180 seems fine.
It first starts off with some lag on mouse movement, 10 seconds later the system can only be rebooted with a hard reset. If I'm just in time to close the process before the freeze, I'm able to save it from happening =)

-H 0 runs SHA256 singlethreaded on your CPU, only use for with singlecore CPU and affinity set to one core, I suppose.
-H 1 runs SHA256 multithreaded on your CPU, best option but might suck a lot of CPU cycles
-H 2 runs SHA256 on the card itself, frees your CPU from its burden so it can be used for other stuff. This however made my hashrate drop from 333khash/s to 285khash/s on my gtx760, but I'm happily mining Heavycoin next to it, so it compensates.

-C parameter is one you'd have to experiment with. It runs a cache (not sure what it caches ) but it could speed up some cards. Just try out the different options and see what works best for you

a) It's for fun, use the right SHA256 altcoin at the right moment, and you might just shorten that ROI a lot while having good ol' fun.
b) OC'ing them can be fun too.
c) You will get some BTC out of them, and if the BTC course does another big high, well.. Then you're one of the lucky ones with a BTC in its wallet when its 2000$ each

Mining is speculating too, remember that

Well, you might try playing with -H 1, which will run the SHA256 calculations multithreaded instead of singlethreaded.
-C 2 seems to have the worst effect on my GTX760, -C 1 works the best, no cache (-C 0) is in the middleground.
-i 0 might be an option, but you will experience some lag on your screen. If you plan to use your system while mining, keep using the -i 1.

My 330m from my laptop only gets to 11khash/s with optimal settings, 9.5 with -i 1, so I guess those numbers might just be right.
