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:

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.

Speaking of which, is that bitalign thing normal? I’ve never seen it before doing neoscrypt with SGminer…
-
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.I see most people use our customised CGminer, so I test my kernel with it. If you are going to put it into SGminer, replace WORKGROUPSIZE with WORKSIZE. Everything else should be the same.

My tests showed 47kh/s with 3.7.7c and 3.7.8 with my unlocked 6950 -I 12 -w 64. Thanks

You may increase work size to 256. It helps these VLIW cards a little.

Yes it’s perfectly normal to see that in sgminer.

Folks, might be a silly question but would neoscrypt work with onboard intel graphics ?

Intel HD graphics of Sandy Briidge and newer supports OpenCL, so it will. Performance isn’t going to be impressive though.

ghostlander, It sure isn`t. Just wanted to make sure its in the arsenal :) thanks

Do the APU’s support OpenCL? My wife’s PC is due to get upgraded sometime soon, and that might effect what gets built.

found something like this:
so i guess it will work?
AMD Embedded GPU and APU Driver 14.201.1009 for Windows 7/8Thia is the latest graphics driver for AMD’s Embedded GPU and APUs. Windows 7/8/8.1 32-bit and 64-bit supported.

Of course they do. Even old Llano with 400 pre-GCN units is a good thing to have. Kaveri with 512 GCN units is even better, though I still prefer 4 real cores of Llano to 4 CMT cores of Kaveri.

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 it use? Don’t work for me with cgminer 3.7.8. Cards in rig: 6950,6950,6870,5870,5870. Drivers 13.12, Windows 7 x64 sp1

What is the content of your .bat file? I suggest to rename your feathercoin.conf and start with a simple 'cgminer’command.
Then enter the url, username and password of your pool when prompted and try that. If the miner works write the config file to disk and start tuning from there.
If it doesn’t work, I leave it to the Wolf0 and Avehre to find a solution
