GTX 750 Ti @ 1400 = 285KH/s with CUDA 6.5 or 280KH/s with CUDA 7.5

Although I've somehow broken Stratum in the process, so it's solo mining through Getwork now.

These are nice results. Have you open sourced the code or compiled a binary? want to see how you did it.

No surrender, no retreat, no regret.

NeoScrypt CPUminer v2.4.3 is ready.

It incorporates the latest NeoScrypt reference code improved over the last half a year. There are minor performance improvements for Linux and Windows, major ones for MacOS X which gets the SSE2 4-way mining fixed.

mining easier than before

Many miners with Radeons switched for ETH, though FTC is also very profitable now with increased price and decreased difficulty. Reminds me the old good times.

Hi guys, I have a hd 7750 in Neoscrypt produces 111 kh / s, it is normal ?. It was established Catalyst 14.6

That's expected for 512 shader units. About 20% performance of R9 280X.

Hi,

Can someone please help me to setup on ubuntu 14.04.

not sure what to type as code. please post step by step code. i appreciate the help. I managed to install on my pc with R9 280x and currently hashrate is 515kh/s

thanks

Hi,

Thanks for the code. Will check it out later tonight. Can you please assist me in downloading the correct driver version for MSI R9-280X Tahiti needed for the best performance on Windows 10 64bit.
What is the best feathercoin pool to mine on?

Thanks again for the assistance.

Barry

Windows 10? Catalyst 15.7 probably. Although it shouldn't be of much difference there.

The best pool is the closest to your location with low fees and as low as possible downtime.

I have crimson 16.1.1 installed. attached is a screen shot for error. can you please assist? https://www.dropbox.com/s/giv1zx6hfpwth1c/Miner.jpg?dl=0 thanks

You're right, if I added "# define VLIW 1" into `neoscrypt.cl', just after :

Code:

#define VLIW 1

I got this error :

Would be a problem with (enough of free) memory (HD7660D can allocate 256MB at maximum, if I'm not fallen), for example ?

Yes, it doesn't seem to support bitalign. You can allocate more memory for your APU in the BIOS, 512Mb or 1Gb. It should work with -I 12 for 256Mb.

HD7660D is a VLIW4 design which should be capable of some 60KH/s @ 800MHz. I'm almost sure the OSS driver doesn't expose any GPU specific data to an OpenCL compiler, so you have to set it up manually. Add "#define VLIW 1" somewhere in the kernel beginning. If there is no support for cl_amd_media_ops, change it to "#define OLD_VLIW 1"

cl_amd_media_ops is for bitalign/bytealign mostly which are not used in v6 directly. The compiler is supposed to take care of this, but it doesn't do well in the drivers newer than 14.7. It won't be an issue in the next release.

Hi ghostlander,

thanks for amazing job! You're right, that isn't an issue in new 0.9.2 version anymore.

And also, I removed "static" from `neoscrypt.cl' source file (this string is three times there), and now the error "OpenCL does not support the 'static' storage class specifier" is gone. Great! But with --neoscrypt option, nsgminer exits very quickly - sometimes it lists current config and then "Segmentation fault (core dumped)", sometimes it gets this fault immediately. Unfortunately there is no dump file (even if I added --verbose option) for further analysis.

The same nsgminer, with option --scrypt, or without algo-option (it means sha256 algo) runs fine. Well, the hash-power is really ridiculous, but it's not just related to OSS drivers, it's also because I'm testing it on very weak IGP/APU (Radeon HD 7660D). If everything will be fine with --neoscrypt there, I'll try on more powerful/faster discrete AMD cards too...

Finally, within compilation of nsgminer from git repo, I didn't add AMD APP SDK; I guess it doesn't make a sense with OSS radeon.ko driver ... or would be there some performance impact also in this "specific OSS case" ?

Thanks for your help and your work on nsgminer again!

10MH/s is much better, but still not enough to compete with these ASICs. There may be even faster ASICs by the time Pascal comes into production.

The (28nm) R9 Nano is already 1/2 the speed of the announced unreleased ASIC if you messure hash/Watt. With a modded kernal you can reach 20MHASH per card. for $2000 you can buy many cards..

Pascal is rumoured to be 12 times faster, and will be released in 2016. (16nm)

The announced asic is slow. It should be 2.3 GHASH / 700Watt. to beat the competition.

I'm sure this ASIC is of a very inexpensive design and production. Something like 150nm and multiproject wafers. Indeed it's overpriced. Any subsequent designs should be much more impressive.

r9 NANO 0,141 MHASH /watt (1/4 of the asic)(fury 2015)
