Topic: [ANN] sgminer v5 - optimized X11/X13/NeoScrypt/Lyra2RE/etc. kernel-switch miner - page 125. (Read 877859 times)

i like the potential but cant get anything like the speed's i see,,, my 290's were those unlocked ones from new then flashed with stilts 290x bios (which does increase clock speeds ect)   I  have to go to work size 128 to run this miner cant get off i13 but still running on 14.6 drivers 

Try intensity 13, gpu threads 2, worker size 64, thread-concurrency 8192

thats good hash tccd

what drivers you using ?

Thanks. Now i am getting 100khs but still no way near to 200khs. 1100gpu engine and 1500mem clock.

You need the develop version of SG 5.

Don't use that one - use Nicehash's build. Hawaii chips are 290/290X.

For 7970, look up the 280x settings.

Could this be merged with sgminer-dev/devel branch or did you hardcode some Hawaii stuff in this version?

7970 just 38khs on Neoscrypt  first time, whats the setting for NEO and which is the best miner?

What's rest of your config like?

I've got it too, and that's my plan

Humm. I'm not sure why I'm showing you this, maybe because I have something to brag and I like bragging.

I made some small optimizations on the Wolf's neoscrypt kernel. Now it does 430khs on 280x, 450khs on r9 290, and 260khs on r9 270.

I'm thinking what I should do with this. There's no point to release this to public as this would just make net hashrate rocket and everyone would still get the same profit.

Maybe you could hand the compile job over to someone you know so we would all know it was safe :-)

It might be better if kernel was only released in binary form (*.bin), and not the source. The binaries could also be signed so if there is a leak, you could tell who has leaked..

Binary distribution would also eliminate the problem with different Catalyst versions. For example current neoscrypt kernel only compiles properly on Catalyst 14.6, anything newer or older generates HW errors or very slow speed. Then again all scrypt kernels compile best on 13.12, compiling on 14.x works but gives perhaps 30% lower hashrate..

The compiled binaries can be moved around with no problem. I have used the 14.6 neoscrypt binary with 13.12, and it works fine with full speed. Recompiling it under 13.12 halves the hashrate..

Still the biggest problem is, some users have 200 gpus and some have only a few. If you are selling a kernel, the price should be different! It should be "per GPU" price, but it is impossible to control. If the price is fixed, some big rig owner can easily pay a few BTC to get the kernel, and then ruin the profits for all "hobby" miners.

I like to optimize these just for my own fun. And obviously it's good if you get some profit from your work. But at the moment it seems the best way to profit, is just keep the kernel to yourself and enjoy the increased hashrate.. Any wider distribution will just lower my own profit.

say I want to do some precalculation on blake256 for lyra2RE, where do I put that ?
midstate ?

ps: such a nightmare modifying sgminer  
(how something which should take 5min (time it took on ccminer) will end up been done in 5hours...)
