[Dev] NeoScrypt GPU Miner - Public Beta Test
-
Workisze must be 64, or a multiple of.
-
64 seems best with i 13
-
If there is any speed difference between 14.7 RC3 and 14.6 RC2 while running 14.9.x it’s so minute that I can’t even tell.
-
I am running AMD Catalyst 14.9.2 Beta with the 14.6 RC2 OCLs and my 290x is getting 320 Kh/s. You might want to upgrade drivers to get that extra 100 Kh/s out of your 290x.
Also,
AMD HD7950 (Hynix) 274 Kh/s
AMD HD7870 (Elpida) 116 Kh/s
AMD HD7850 (unknown) 120 Kh/s
Managed to get ~240k on the 290’s and 220k on the 290x, upping to the 14.9 drivers now and see how that goes.

I want to thank both Wolf and insanid for all of the help they have given. I think it is great that Wolf is sharing his work with everyone, given that mining can be a very competitive endeavor and that insanid has been so helpful getting everyone up and running. I learned a few new tricks today and have gained much more appreciation towards what goes into optimizing mining.
Thanks again

You’re welcome :) I feel that with Neoscrypt mining has been given back to the hands of enthusiasts, and seeing how the average person can now mine again, we all should help each other out.

Well with the 14.9 installed and the 14.4 pack from here, trying intensities from 11 to 16 and all sorts of combinations, I managed to come up with 255k on the 290’s with 3 different combinations of settings and 245k on the 290x’s with one, 240 with another, and 235 with the 3rd of the settings that did 255k on the 290’s…
290’s = hynix
290x’s = elpida
Back at it tomorrow… >:D
BTW wolf0 said work should be a multiple of 64, I’ve found multiples of 32 give me the best results. (IE: 96 beats 64 in many cases)
-
Epic… This is working out well!
-
I found a -w 112 also works well for me, picked up 4-5 kh per card
-
HD6970: 19.5KH/s to 50.5KH/s and no HW errors!
Thanks to a much better global memory management with burst writes. Also tried a trick with copying a workgroup buffer to local memory and writing back asynchronously to global memory through async_work_group_copy(), but it didn’t work out (36KH/s and 15% of HW errors). A 2.5x speed increase is something to celebrate anyway. Anyone cares to donate towards drinks, whores and blackjack? ;)
-
How does 117kh/s sound for R9 270 non x cards? 1100/1450? -I 13 -w 64?
Not sure what I’m doing wrong but couldn’t get p2pool or localhost to work with sgminer 5.1, how to http://us.mine-ftc.co.uk:19327 command line?
stratum+tcp://stratum.wemineftc.com wasn’t a problem to get working.

Excellent news for people with the older cards!!
CHEERS!!

Nice will try it very soon and report back, Thank you!
Edit: What miner versions have been tested? Be nice to know what all this works with and drivers.

How to get Wolf0’s latest neoscrypt kernel working on AMD Catalyst 14.9.x
You do not need to uninstall AMD Catalyst 14.9.x drivers, and only use AMD Catalyst 14.6 RC2 drivers with this method.
Download the latest sgminer-5.1.0-dev from https://www.nicehash.com/software/#sgminer
Open and edit neoscrypt.cl in the folder you extracted sgminer to, and replace all text with the new Wolf0 neoscrypt kernel. Here’s the link to the newest kernel:
Download AMD Catalyst 14.6 RC2 OpenCL DLLs from here:
https://drive.google.com/file/d/0B06N0FYvyFgDMDF6eGVDUDZzWXc/view?usp=sharing
You will notice I have included 13.9, 14.4, 14.6 RC2, and 14.7 RC1 AMD OCL DLLs. We will be using contents of the 14.6 RC2 AMD OCL folder.
Copy all of the DLL files from the 14.6 RC2 AMD OCL folder into your sgminer folder.
Start the miner with settings w64 g1 I15, or whatever custom settings you prefer.
There should not be anymore HW errors due to 14.9.x drivers.
Optional: You may delete the 14.6 RC2 AMD OCL files from the sgminer folder; however, if you delete the bin files generated by sgminer, the next time you run sgminer you will get HW errors.
I have included a sgminer-5.1.0-dev 7z file with all of the changes listed above here:
https://drive.google.com/file/d/0B06N0FYvyFgDeHBnTVEtR3BVN2c/view?usp=sharing
Edit: Updated to AMD Catalyst 14.6 RC2 AMD OCL DLLs due to massive speed improvements vs. AMD Catalyst 14.4 AMD OCL DLLs.
If this helps you, please consider hitting the up arrow on the right side of the post. Thanks :)
760GTX and 660Ti almost double the hash 21/22 to 37/40 -I 10 -w 64 or 32 tested has about the same with either used. Nice going, keep up the good work Wolf0. :)
Edit: update -w 128 dropped off about 2kh/s per card but - w 16 pushed them up now 40.5kh/s 660Ti/43.25Kh/s 760GTX -g 2
Nvidia driver v 326.80

any updates/news on nvidia miners?
-
Well, I got woke up for an outage at work that is now solved, so I’m back at it for a few minutes while I get drowsy…
Tried out my existing settings from the 14.4 OCL on the 14.6 and 14.7, and my hash rate jumped from 255/245 to 299/294 for the 290/290x.
As mentioned earlier, indecipherable difference between the 14.6 and the 14.7.
Thanks insanid for posting those!!!

Scratch what I said about sgminer and nvidia as its not producing any shares and some hardware errors. :-

No problem! I am glad to hear you have your 290s running near optimum hash rate with Wolf0’s kernel. Try these settings on the 290x to see if you can get higher hashrates closer to mine:
AMD r9 290x (Hynix):
w64 g2 (g2 is REALLY the key here and ONLY for 290x in this case) I14
Elpida cards may or may not see an increase in speed with these settings.
-
That was one of the 3 settings that gave me the highest speeds, but it was number two, and gives me 297/284.
The best I get is from I13 g2 w96.
GPU 1 & 2 are 290x’s, GPU 3 & 4 are 290’s.

I guess my 290x is special. It’s a Sapphire Vapor-X 290x with Hynix GDDR5, so that could be it also.
