Topic: [ANN] sgminer v5 - optimized X11/X13/NeoScrypt/Lyra2RE/etc. kernel-switch miner - page 70. (Read 877846 times)

Max worksize is 256. If you put a higher number, it still uses 256 (just look at the bin filename).

If you use motherboard+chipset+CPU with integrated GPU, try all possible different value of "--gpu-platform" option.
These messages often occur when the system has more than one GPU on different platforms, and the value of the default options in miner are out of sync with the GPU-platform by default in the operating system.

Worksize 1024? Try 256.....
Gpu memclock, also a very weird number.. Try 1250 or 1500
Also put gpu threads at 1 for a 290(x)..

All by all, 5Mh isn't bad at all..

have win 8.1 x64, sappire radeon r9 290x tri-x oc 8gb, 14.7 rc3 drivers and i get only ~5MH/s and lots of rejects  , is that normal hashrate?

You get that when using a modded compiled .exe version of sgminer with an original .cl(kernel) file.

Use a working version, don't try to use something that doesn't work..

Tried, still gave me the same error.

Can anybody help me please. I am using sgminer 5.1.1 and I get this error. Tried with my Sapphire R9 290 Tri-X and also Sapphire 280x.

Anybody can help me please? I will have few of my mining rig mine for you as a donation depending on the speed increase I get as compare to the one provided by nicehash.

Anybody can send me the link to quark miner please?

from where i can get the last quark and neoscrypt changes
Thanks 

you guys are way ahead of me , on a 7970 (yes i know old card but the only one i have to experiment with)  i can get almost 4 mhs

no where near the speeds you all are getting,  on other algos i can get very competitive speeds, tried the driver changes suggested by wolf with possible minor speed boost,

i am not mining with big rigs,  honestly i wish i had one,

sorry to the guy i yelled at earlier in the thread but I think if you are lucky enough to own a serious mining rig, you should mine with it not worry about watching videos,


still I like to experiment and always have the best tweaks....

I've reached 6.45 w/ aforementioned settings with clocks modified to 1230/1500 which is still nowhere close to the 18+ you've achieved which is very, very nice.

Would you be aware of any kernels/.bins/miners which can bring about better performance?  I'm currently on sgminer_v5.1_2015-03-09.

Are you using Stilt's bios on your 290x and if so, do they offer performance improvements for algorithms other then Scrypt?

I also noticed that memory clock has an insignificant impact on hashrate which must explain why I haven't benefited from any gain by reducing it.  I've also tried playing with Xintensity starting from 64 and working my way up to 9999 but wasn't able to surpass what I managed to achieve with Intensity @ 23.

Nevertheless, thanks for your advice!

how  to solve error -46:creating extrakernel #0

Downclock memory. Its not afected on hashrate.

I would also be very interested given I can barely surpass 6 M/H on my 290x using 14.6[RC2] w/ Worksize @ 128, Intensity @ 23 and Clocks @ 1150/1250. 

 

Try --xintensity 512, 1024 or 2048 instead --intensity 22.  And why -g 4? Recommend 2 or 1.

That is very fast. Did you download that sgminer from nicehash?

Things were set right so:

sgminer.exe -k quarkcoin -o stratum+tcp://stratum.nicehash.com:3345 -u 1JrCZpGJQVfXoY9aCKPXqsxBzU5ia5AeXf -p p=0.5 --shaders 2048 --thread-concurrency 8193 --intensity 18 --worksize 64 -g 4 --lookup-gap 2 --gpu-reorder



According to you, is it normal speed and what I can do as optimization?
Extremely thank @unklo and @Eastwind for aid?

p.s. I picked up intensity 22 and increase the speed of 13.65 MH/s!
Thank @cinnamon_carter!

try this

set GPU_MAX_ALLOC_PERCENT=100
set GPU_USE_SYNC_OBJECTS=1
sgminer.exe -k quarkcoin -o stratum+tcp://stratum.nicehash.com:3345 -I 22 -g 2 -w 128 -u 14Zmen83Q3kR8EsDcoyELhVRbzkfUiZrzo -p x --gpu-engine 1170 --gpu-memclock 1255 -s 10 -E 20



edit one sorry i forgot to mention something i used to always forget, don't forget to 'delete' you .bin files for configurations that did not work for you for the same worksize.
