[ANN][GRS][DMD][DGB] Pallas optimized groestl opencl kernels

[pallas]

Hey, guys. Running 2x7950 GPU's (Asus and Gigabyte). After installing 14.6 instead of 15.12 catalyst my hashrate on mining Diamond Coin increased from 6.2(1st GPU) and 6.6(2nd GPU) to significant 10.2(1st) and 11.09(2nd)Mh/s !!!

Looking for more improvement. Links on first message are broken. Where to get v2 experimental cl kernel, pls ? Send to miner.hid@ya.ru someone kind please.

For best result, you need to get Wolf0's Tahiti bin, see first post.

I've downloaded Wolf's bin on first page. Delete my old .bin files after i copied their names, then pasted Wolf's bin and renamed it to copied string. Correct ?
It gives me significant small hashrate at 700Kilo hashes per card  
What's wrong ? sgminer v.4.1.0(got it from diamond mining page).

does it submit valid shares?
if you look one or two pages back, there are alternative links for the v1 sources.

1-2 pages ago there is a same link as on page №1. Do i need to use this bin file along with v1 or v2 kernel files(.cl) ? If so - where to get them ? Links are broken (((

You should use a bin file OR a cl file (which will generate the bins itself).
Here is an alternative link to the v1 sources:

Got this. Thanks for sharing link. I've downloaded .cl file, deleted existing .bin and tried to run sgminer with following command line:
sgminer.exe -k diamond -o stratum+tcp://eu.miningfield.com:3376 -u x -p x --difficulty-multiplier 0.0039062500 --intensity 22
same results 10-11Mh/s per one 7950 card. The one that overclocked to 1200Mhz core/1450Mhz mem runs 11Mhs. Not even near 18Mh/s that i've seen in this thread. I am using 4.1.1 sgminer, do i need to use other version ?

try with another driver version:

https://bitcointalk.org/index.php?topic=779598.msg8787566#msg8787566

you don't need to install the whole driver, just put the opencl.dll file in the sgminer executable folder and run.

Are u using Linux? I've found some info dating 2014 year saying video drivers under linux(especially 14.6) runs better for groestl.
i've tried 14.6_beta, 14.7_rc3 - no difference at all. also played with .bin .cl files.

btw do u have a hawaii.cl file ? Using groestlcoin.cl gives rejected shares 100% on DiamondCoin
sgminer-5.4.0-nicehash - gives little better +1-1.5Mh/s hashrate

Yes I use linux.
Diamond and groestlcoin use the same kernel.
DiamondCoin is another thing, unrelated to diamond.

Thank you ! Finally i got results that i wanted. Just needed to use groestlcoin.cl in bat file by writing -k groestlcoin. Makes hashrate 15.2 Mh/s for 1100 mhz core and 16.53 Mh/s for 1200 mhz core.  

Wait.... all shares are rejected due to low difficulty

did you put memory to the lowest clock possible?
about low difficulty, try adding this:

--difficulty-multiplier 0.0039062500

EDIT: you should use -k diamond and rename groestlcoin.cl to diamond.cl

no, memory runs at 1450(1st card) and 1250(2nd card).

adding difficulty-multiplier results in much faster output of rejected shares.
renaming groestlcoin.cl to diamond.cl and running sgminer-5.4.0 with -k diamond gives same low hashrate(11 and 12) unless i rebuild bin file. That works !!!! Thank you so much Pallas. Going to put a positive feedback for your endless help.
What sgminer version do you use ?

if you set ram to the lowest possible clock, which may be limited to core clock - 200, you will save power and be able to overclock more.

I am getting 19.3 Mh/s with 7950 @1100, fglrx 15.201.11.51 (Catalyst 15.9 installer) and wolf0 binary in diamond.

[r8st]

I'm getting 24 MH/s per 7950/7970/280x, new AMD 17.x.x drivers, Win10 (got the same on ethos/Ubuntu), and lots of time spent fine-tuning overclocks. To be specific my two 7950s get about 22 each, and the three 280x get 25, 25, and 26 MH/s

Also would like to add, since I am not sure it has been mentioned here... My 2nd rig has 3x RX470s which get around 30 MH/s each with proper adjustments and Wolf's DMD Tahiti .bin. That's pretty good, at least compared to whattomine.com which reports I should be getting around 20 MH/s for each 470. Do I tell them? :-)

why not, he'll be happy to hear that ;-)

[Shivoreun]

A humble question: is there any plans to release optimized kernel for RX 470/480?

I'd like to, but I don't have the card...

wolf0 binary download link please !?


is down: https://ottrbutt.com/miner/wolf-groestlcoinTahitigw256l4.bin 

[Dr.Cupido]

HDD crashed and wolf-groestlcoinTahitigw256l4.bin is gone. Is anybody out there who can reup or send me a pm with a dl link ?
