X11's default intensity was before set at -X 5. Now the default intensity  is -X 19.5. (+30kHASH on the 750ti) (1% faster)

Similar changes in x13 and x15 with around 1% more hash just by changing the intensity.. This is because the simd kernal is using almost half the memory it did before.

thats a great number of increases here ...

ill be testing them in the farm when i get over this disgusting illness / chest cold ... a few more days i think and i should be back on track ...

btw - the donation systems seem to be stable and are ready to go live on wednesday ...

so if your way of donation is via mining to sp or pallas ( or the other devs we have setup servers for ) - then this will be fully functional this coming wednesday afternoon ( adelaide australia time ) ...

updates and instructions will be updated on the op here if you are interested - https://bitcointalk.org/index.php?topic=1089744 ...

NEOSCRYPT dot 59--

The last time I mined Neoscrypt was with dot 57 or before.  There was a "wave" on NiceHash where Neoscrypt was paying well, better than all the other algos.  I dug in and have been riding it, all manually.  There is a real improvement in the Neoscrypt algo, and it is explained above.       --scryptr

[sp_]

Hi
it seems that -g 2 Parameter is not working anymore
with release 1.5.58 on GTX 750TI -x11
not necessary anymore?

Should work, but not sure if it is faster.
I think the gpu is out of memory. Combine the -g 2 with a  lower intensity like -X 5

[sp_]

NeoScrypt   3341   9.9882 *  1144%

Nicehash is currently paying 10BTC / (1 day of GHASH/s/  , so NEoscrypt ismore profitable than quark on all the NVIDIA models..

But this can change tomorrow.


1 GHASH of Neoscrypt is around 1750 gtx 970 cards with the latest ccminer release 59

But Djm34's private kernal is faster. over 200Khash on the 750ti without overclocking.

I don't really have time at the moment, but people can always pledge at my neoscrypt btc address to motivate a bit...

[pallas]

Thanks to whoever donated a couple beers for my neoscrypt work! :-)
(I guess that's the reason...)

[bensam1231]

Here is my contribution to the ccminer-sp effort.
I just posted a pull request:

Code:

Enhanced neoscrypt kernel:
improved hashrate of about 10% (gtx 970)
code cleanup
hardware error printing
other enhancements

Please note that it's not just an hashrate increase, there is a lot of code enhancement and cleanups under the hood.
Also note that I didn't test it on cards other than 970.
Donation BTC address is in my signature.
(Depending on how my effort is supported, I'll see whether to post my future works or not)
Enjoy! :-)

Thank you for your pullrequest. My gigabyte 970 went from 520-540 to 560-570KHASH. The 750ti's seems to be up 5KHASH, but I think will tune the kernals when I get time.

Thanks Pallas for the improvements.

[GarlukKY]

First off, thanks to the coders for all their hard work.  It is very appreciated.

Since Build 54, I have been unable to solo mine quark on my 750 TI.  The recent builds all work just fine with pools, but 54 was the last that will connect to my wallet and actually mine.  Just wondering if anyone else has had this happen.

sp, good work! Just sent some beers to you

Using a Nvidia GTX 850M it seems to me that the latest commits (that include neoscrypt improvements) only slowed it down...
I used the same configuration (-i 13) to run it with release 57 and 59 and the results were the following:

Release 57:

accepted: 1/1 (100.00%), 121.46 khash/s yay!!!

Release 59:

accepted: 1/1 (100.00%), 56.50 kH/s yes!

I only show here 1 accept, but other accepts are consistent with these.

As you can see it slowed very much, there's a reason for this?

I didn't change the launch configs nor the thread number nor default intensity, but what about other intensty values? Do they all give a lower hashrate?
I changed so many things in the code that it's not easy to understant if/what change might have worsen hashrate for that card, without having the card itself to test with.

[zTheWolfz]

Seeing a bit of a loss on 59 over 57 on the 960 as well. -i 22 used with both and has been the best -i from 54 onward until now for this card.
I tried -X and couldn't find anything that made it any better then -i 22.
I'll test a little more and see if there is a better spot for the new release.

This is quark right?

try  -i 22.9 (the default for 750ti)

Do you have more than one card in the rig? Is the card trottling? Check the temperature, if it reaches 70 degress c it will automaticly downclock,. Also make sure your card is in the p0 state. Defalt is p2


Performance modes
P8 = idle clock speeds and lowest power consumption
P2 = the default mode used when your PC boots or no drivers are installed.
P0 = Gaming/Load. This mode only accepts boost/offset values


Did you build it yourself? Use cuda 6.5 and not cuda 7.0 or 7.5

[sp_]

sp, good work! Just sent some beers to you  

Thanks for your support More beers for me.

@wolf: cheers.

[pallas]

My cards stay in P2 while mining (there is no X server running).
If I set persistance mode, they go to P8 when idle.
I think they are mining fine (using power boost, throttling, getting as near TDL as possible, etc.), but maybe with P0 they can hash more? What's your experience?
Thanks!
