Is there any options for backup pools.  Could I run a stratum proxy of some sort to get around the fact there is no backup pools in cudaminer.

Is cudaminer dependent on processor performance to give better hash rates?

with -H 0 and -H 1 options the CPU can become a bottleneck. Otherwise no.

-H does basically nothing but drive up the power draw for me, CPU too weak?

Yes the nVidia submitted kernel is expected to run 10-20% faster than Dave Andersen's kernels.

*sigh* I was almost hoping that was not the case. Now In good consonance I can't leave it be and only hash @ 500 kh/s a card.

Back to fucking this some more.

500 is fairly good on a Titan without overclocking. I've got my solo titan at 620 with +155 Core -502 Mem, try it.

Is that using the latest cudaminer? What kernal settings are you using?

Yes, latest version cudaminer, tried both x64 and x86 versions, same within a few khash of each other.

Settings are: -m0 -l T5x24 -i 0 -H 1 currently, although I have tried different values and none seem to make much, if any, difference.

I was also in the same boat after receiving my 750ti and not being able to break past 275ish until I started getting really aggressive with memory clocks. From my experience, the card starts hitting a power limit when the memory clocks get around 650 to 700 and while the overclock still seems stable then, the core overclock is reduced the more I push the memory.

My current working settings are +75 core +650memory along with -l T5x24 -H 1 -i 0 -m 1 and it gets me about 335-345khs +/-15 with less than 0.5% rejects. I only have one card running on the main 16x slot and the model is the EVGA ftw acx edition with the extra 6pins power connector.

Good luck, I hope you get your 300+ out of your card.

Hi all,

I got the problem with compiling cudaminer on my Visual Studio. I use the package cudaminer-src-2013.12.18

While compiling, errors occur :

1>ptxas : error : Entry function '_Z25fermi_scrypt_core_kernelAILi11EEvPj' uses too much shared data (0x6e14 bytes, 0x4000 max)

I think that fermi_kernel.cu can't be built with compute_12,sm_12 flag (use too much shared memory) , I should use compute_20,sm_20 instead.

But the problem is I only have a GPU card with capacity of 1.2.

It's better if I can compile legacy_kernel with  compute_12,sm_12 and fermi_kernl with  compute_20,sm_20 .But I don't know to do this in VS.

Please help me.

Thank you.

im mining SUN now, works ok

Now I can see my hash rates go up a little bit when adjusting the overclocking settings, but still no significant improvement. I am getting into the mid 290's, not quite hitting 300 kHash mark I would like to see as a baseline, and still hoping 320 is possible.

I can't get near 300 kHash/s either, and worse: I get bluescreens when I dial up the overclocking.

Yeah, I get constant crashing at the 135 core 700 memory in the cryptomining blog article. I had to back it down to 100 core, 400 memory to get it stable, and would like to see it run overnight before even making that call.

I have tried almost every configuration I have seen posted and about the best I can get is ~295 from each. I haven't even bothered to measure power consumption yet, but am thinking these are not going to work out quite as well as I hoped.

The Chrome trick also doesn't seem to do anything for my particular setup.

Have you tried the unlocking wattage from 38.5 to 60 yet?

A thought just popped to my mind while solo mining with cuda miner:
Would it be possible to have an feature which would make the miner pop up on top or flash yellow in the bottom bar when it finds a block? Of course this would be a parameter which should be activated separately. Would be useful at certain situations, eg. A low hashrate miner like me soloing, waiting to find a block just to mine something else. The wallet will display a message of incoming transaction, but if it's orphan you'll miss it.
Or it could pop up/ flash if it has multiple rejects. Would this be hard to implement?

can i mine quark coins? how?

cudaminer is a portable C++ application (the original cpuminer code even was pure C, but Visual Studio 2010 couldn't handle the C99 aspect of it, so I converted parts to C++)

Adding GUI features, possibly OS dependent, would undermine the simplicity and portability of cudaminer.

I recommend you use a graphical management tool like Cuda Manager, and petition the author to add your desired gimmick there

can i mine quark coins? how?

"Quark is protected by 9 rounds of hashing from 6 different hash functions making it one of the most secure currencies ever designed. "

Nope. Not on the road map. I have no intention to optimize 6 different hash functions for CUDA.

I am trial mining AUR now (Aurora Coin, some kind of Icelandic specialty, like Bjørk)

[cbuchner1]

I got the problem with compiling cudaminer on my Visual Studio. I use the package cudaminer-src-2013.12.18

why did you pick such an old source package?

I am wondering how I was able to build this with CUDA 5.5, if you cannot

Are you making the Release build?

In this old cudaminer release the Legacy kernel is meant for Compute 1.x devices.

This coin 50% premined for Icelandic people. Any profit?

of which only a few percent will likely be claimed (at least initially). The rates went up significantly yesterday and the coin should currently be profitable.

the only risk involved might be that someone has an SSN database of iceland and defrauds the coin devs by claiming all the money himself (maybe through a large number of wallet addresses, and through many VPN connections to fool IP filters)

[whitetoo]

This maybe a silly question, or perhaps not the right place to ask?
Is there an easy way to estimate a keccak hashrate from a scrypt hashrate and vice-versa?

[patoberli]

Not really no. Some very low scrypt cards can get surprisingly high keccak numbers.

[ManIkWeet]

I was thinking if it is possible to implement some kind of progress indicator for autotune, as it can take a very long time with -L 3-7?
Other than that I am (so far) not seeing the 1khash/s improvement on YAC yet, best improvement is 0.6khash/s and GPU usage went from 80% to 99%.
Going to autotune with -L 7 now... results soon!

[jack80]

Anyone mines with a nvidia 740m? I am mining to 65 kh/s with these settings:

cudaminer -o stratum+tcp://website:port-u xxx-p xxx

and nothing more 'I should add some other string?

thanks .

you can run autotune with the -D flag and abort as soon as you see that there's not much to be gained from waiting longer. It's also a good idea to log the output to a file for later review.

the 2>&1 syntax merges stderr and stdout into a single output stream.

cudaminer.exe  -D -d 0 -l T   2>&1 >autotune_logfile.txt

[cbuchner1]

Not really no. Some very low scrypt cards can get surprisingly high keccak numbers.

would you have any examples for scrypt duds & keccak ace cards?
