Tried 14.4, 14.6, 14.9 all 100% HW errors with his stock config. For straight 290s w112 is about 3% faster than w64 even in the older build, this is not the case for 7970,50, 280x…etc.

Unless you are using the exact same environment as him, no configuration will work well. I already brought this issue up to Wolf, and he’s looking into building sgminer either with dynamic links, or static-built against windows 14.6 drivers. I REALLY hope he builds dynamic so that we can use 14.9.x or 14.11 drivers and just swap in 14.6 RC2 OCLs. I game on my miner with the 290x, so it’s a big thing for me to revert back to older drivers and lose game-specific fixes.

Hmm, well I cant get anything other than HW errors either for now. Some people seeing result others cant get it to work. Lets wait and see.

As I said before, I did manage to mod an older version by replacing the neoscrypt.cl with the new one and updating to: --worksize 112 -I 15 -g 1 --thread-concurrency 16384, gave my slower 290 about 12KH/s more and my faster one saw little to no boost.

Wolf’s builds sgminer binaries with static-linked libraries, so putting in AMD OCL DLLs into the sgminer folder won’t work I am afraid :( You must not be using the right AMD Catalyst drivers.

Edit: Also, he has mentioned before to use multiples of 64 for the worksize. 112 is not a multiple of 64.

Edit: His sgminer build for Hawaii will not work with Catalyst 14.9.x or above.

Wolf0s newest Hawaii update is really only meant for 290s and up. The 280x has a Tahiti architecture.

I think I know.

Of course you do. Wolves are intelligent creatures :)

Here’s a newer sgminer-5.1.0-dev build (2014-11-13) for everyone:

https://drive.google.com/file/d/0B06N0FYvyFgDMWJ3b1F6VHpoZnc/view?usp=sharing

It includes AMD OCL DLLs from Catalyst 14.6 RC2 (OpenCL 1.2 AMD-APP (1526.3)) and the latest Wolf0 kernel from github.

It includes some bat and vbs files I use to auto delete bins and set environmental variables.

Also has other small fixes from sgminer devs that aren’t neoscrypt related.

Here’s the latest AMD OCL DLL archive I have put together:

https://drive.google.com/file/d/0B06N0FYvyFgDQUdQTjVJeC0xblk/view?usp=sharing

It now has 14 sets of AMD OCL DLLs from Catalyst drivers. 14.6 RC2 is still the fastest.

R9 290x 327-328 Kh/s

Same, but with rawintensity:

rawintensity8192 g2 tc8192 w192 lookup-gap2

Not seeing any magic dust in -x for neoscrypt like I did with scrypt mining with the testing I’ve done so far. :-

That’s not bad hash rates for a 270. From what I recall, 270 is very similar to 7850-7870. My 7950 got a 22% increase and 7870 got a 9% hash rate increase using similar settings as you. Obviously, all cards aren’t made equal, and some like these settings, and others don’t.

file size is not same…

bins now created ok, no hw erros with 14.9-14.11 catalyst

You have to remove all amd opencl DLLs from the sgminer folder.

file size is not same…

yeah the checksums aren’t going to match, most likely because they are re-signing the drivers on every release, which is going to end up with a different checksum every time even though versions are identical.

yep, not talking about catalyst version, but actual driver version

AMD Catalyst 14.9 (14.201.1009)

now trying 14.9rc2, first look seems its fastest(like 0.5%)

AMD hasn’t changed the OpenCL 1.2 DLLs from 14.6 Beta all the way to 14.11. I doubt there will be any speed improvements.

I take that back. They have changed the AMD OpenCL drivers; however, in my testing anything higher than 14.7 RC3, which uses the same OpenCL 1.2 1526.3 as 14.6 RC2, you will get HW errors trying to generate bins. This new kernel from wolf doesn’t appear to get any boost from newer drivers after the bins are created.
