TSIV, DJM34 where are your private kernals?

Everybody seems to use my optmized kernals for some reason.


someone is renting lyra2v2 at nicehash for 0.29BTC and mine  0.34BTC on the yaamp clone multipool.

I have one card I use on this computer for mining and watching netflex at the same time....I can only do this with R43. Is there an intensity setting that I can use to do the same thing with R71?  Thx

Set -i 20 (19,18,17,16 or less)...

I forgot to add that there are 2 other cards using r71.  
EDIT: -i 20 did it..... thx
Now to get only one bat file that will do that to -d 0   and leave -d 1,2  alone.


-p x  -d 0 -i 20  -d 1,2  that didn't work.

Let me start over  
I have 3 cards 750ti on this computer and with one bat file I need to set the intensity of -d 0 to -i 20 ...but leave the other cards at there normal intensity.

@sp   yes lyra2re2 at .3400 and BTC  at $312 usd

There was a bug in this code that was fixed in one of the 6x releases. don't remember wich.

Thx but is it possible to leave the other 2 cards without the intensity because I don't know what is the default intensity is.

any idea about mining ETH with 750ti?
is it profitable in comparison with other algo?

[Epsylon3]

Thx but is it possible to leave the other 2 cards without the intensity because I don't know what is the default intensity is.

-i 0 should use defaults, so something like  "19,0,18" should work

Not on Windows. Using my CUDA ethminer on Linux, the 750ti has the best hashrate/watt. That said, the overall hashrate isn't that great, ~8.7MH on stock clocks. You're up against massive Radeon farms where each card easily does 25MH/s. Besides that, the TLB trashing issue will eventually affect the Linux version too, reducing hashrate even more. I think you're better off with the popular ccminer algo's.

You can also check here: http://badmofo.github.io/ethereum-mining-calculator/ . From what I've read you should subtract about 10% for pool mining.

I have mined ETH on Linux with my 750Ti:s
But i found it very buggy, very hard to know your real hashrate and stuff.
I had to rely on the hashrate reported by the pool and it went up and down alot.
I also had alot of rejected work with the nvidia rigs.

So, yeah it work but if it is the best to do with 750 cards i dont know.
My cards did around 8Mhs at most. But the hashrate seemed to go up and down alot.

On my AMD rig the hashrate was like constant and no hazzle at all while mining ETH.

[Slava_K]

On Nicehash my home rig (51.5 MH) show crazy hashes... 120 MH accepted and 200MH!!!! rejects...

POOL-SIDE PROBLEM? --

Same thing here.  The problem just started today, my ccminer updates (dot 72) are several days old.       --scryptr

EDIT:  Shortly after the last payout, the problem went away.  My average paid hash-rate was about the same (and correct) throughout the problem, but the error rate was erroneously high poolside during the problem.  My rigs were getting 98% + acceptance reports in the console.

Epsylon3 Yes thank you...that works and only one bat file.

luffa512/doom 5% faster. Tiny speedup qubit.

Hey
I only have 1 graphics card so I let my computer mine digibyte while I am sleeping at night. So when I wake up I can find free coins in my wallet from letting it mine at night
Using the sp ccminer I get 270 mh/s skein.
But using the tpruvot ccminer I get 400 mh/s skein.
That difference of skein hashrate is my only complaint.
The sp miner gives me about 5-10% greater speed when using other algorithms though.
For example I get 9.8 mh/s x13 hashrate in the sp ccminer vs 9.4 mh/s x13 in the tpruvot miner.
62 mh/s myriad-groestl in sp ccminer vs 57 mh/s in the tpruvot ccminer.

Which card is this? and OS.

Skein should do 270 MHASH on the gtx 970 in release 72(cuda 6.5 windows x86)

If you see in the code of the tpruvot branch you will see this:

/* Merged skein512 80 + sha256 64 (in a single kernel) for SM 5+
 * based on sp and klaus work, adapted by tpruvot to keep skein2 compat
 */

And this comment:

Merged skeincoin algo for SM5+ devices
Should give same or better than SP and klaus versions

Keep old code for older devices and skein2 compat

Linux perf: 750Ti 78MH/s and GTX 970 260MH/s

I have windows 8.1 and titan x
Now I updated to latest version sp ccminer 1.5.72-git from http://cryptomining-blog.com/6189-updated-windows-binary-of-the-ccminer-1-5-72-git-fork-by-sp-for-maxwell/
And updated my cuda to version 7.5.18
Now the hashrate appears to be bigger but now it says "reject reason: duplicate share" please help  

Use cuda 6.5. This fork is made for cuda 6.5 and not 7.5.

(But cuda is only needed if you are building yourself) If you run the exe, you just need the latest drivers.


in the ccminer.cpp file, try to move the case ALGO_SKEIN above the minmax = 0x70000000U and recompile.

if (max64 < minmax) {
         switch (opt_algo) {
         case ALGO_KECCAK:
         case ALGO_BLAKECOIN:
         case ALGO_BLAKE:
         case ALGO_PENTABLAKE:
         case ALGO_WHC:
         case ALGO_SKEIN:

on your latest release72 mining skein on pools gives a lot of rejects, tried different diffs:
