[Dev] NeoScrypt GPU Miner - Public Beta Test

Wolf0

first look for 280x only hw, hash down by 70%

will try later with better time

drivers: 14.200.1004.0

You MUST change your settings.

i tried raw + I 13+ w 64-256

have no time to play more now

Running 2 x 280X’s and getting 310-314 with them.

No improvement after all testings only few kh/s on 280X. With 13.6 rc2 didn’t worked at all. Strange thing is when I use old bin build on older sgminer also on 14.6 rc2 it works but reports same speed. Latest version builds bin 3 times bigger than old one with same settings.

I’m only getting this,

14.7 rc3 drivers

[19:21:15] Specified platform that does not exist
[19:21:15] clDevicesNum returned error, no GPUs usable
[19:21:15] All devices disabled, cannot mine!

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

I’ve only seen it help on Hawaii - doesn’t mean there aren’t magic settings for other cards.

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.

It might work - it’ll probably be dead slow, though.

I think what makes more sense is that it will use the version I linked, regardless of what you have - I need to get an updated Windows version of the driver files to build against.

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.

Yeah - you’ll probably have to build it for now - I’m finding the right files.

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.

Well, in previous releases the worksize multiple of 64 thing has been complete hogwash… No reason to start assuming it makes a difference now.

As the kernel gets better, it will become more true.

slowhash

Anyone else get this with GPU temps? (GPU # 4) I never saw it before using wolf0’s kernel…

Palad1n

And topic is dead…

slowhash

Since the neo-scrypt development is stalled, and waiting for wolf’s latest kernel and SGminer modifications to get compiled for windows with the proper files, it appears that this thread is as well.

wrapper

I’m not too well, so can’t mess about too much. I’ve tried sgminer.exe windows compile with R9 270 again. It just stops immediately after starting up. Gone back to cgminer 3.7.7

Is that because sgminer doesn’t work with p2pool’s stratum?
