Myriad-groestl: I tried splitting the kernel into two parts, groestl and sha. I was almost sure it would be an improvement but it is a little slower instead (and it requires a custom miner). It could fix Tahiti slowness, though. I don't know yet because I didn't have such a card ready on the rig to test.
I can provide access to test

How did you get this expectation? I also tried that but for very different reason: giving small devices chance at a more efficient task switching. It wasn't worth it even in that case (surprisingly).

The two algos are very different and I was hoping for a lower registry occupation (especially for sha, which in addition doesn't use LDS) and, thus, more waves in flight.
It's not the case for hawaii but it might be for tahiti, I'll test it as soon as I have some free time and can access the rig.

Could someone please share their hashrate with r9 285? I'm curious to see if it outperforms the 280 and how much power it uses.

on diamond mining ,my msi r9 270 oc 1060  does 9.4mh with pitcairn.bin

so i m now testing r9 380 tonga

i have sgminer dmd 4.1.0 , last drivers

i remember i replace the diamond.cl in the past
with default bin it s running at 7mh  stock gpu speed and oc to 1080 7.1mh

with wolf 280x bin (if i remember it s that one) it runs at
15.4.mh asus strix 380 2G stock @ 970   and 17.06mh oc @1080
15.8mh Sapphire Nitro R9 380 2G D5  stock @ 1000  and 16.8mh oc @1080
   
i don't know why Sapphire are slower
most of the link here are dead so i can't check if i have the good bin's & cl

so they slower than the 280

on skein i m doing 208mh @1080, and reported speed of 280x are 185mh if i remember

here is the original bin what sgminer build

http://www.megafileupload.com/no4y/diamondTongaglg2tc10624w256l4.default.bin

Are there binaries/kernel for Myr-Gr?
It seems only gr-gr are posted?

Hi!

I try to mine DMD. BTW, the links from your first post are not working (still can't try version2 bin).
I've found groestlcoin-v1.cl in the sgminer distribution.
On my HD7790 I get ~4.0 Mh on standart diamond.cl, and 4.7 Mh on your optimized kernel groestlcoin-v1.cl.
The fastest results I got with Wolf0's Tahiti bin. It is 8.5 Mh. Unfortunately, it's still too low to get the DMD mining profitable on Radeon HD7790.
So, I'll have to stay on MYR-Groestl, which gives 17.5 Mh on optimized kernel from ghostlander.

Which version of catalyst did you use? Usually 15.3 gives best results.

Can you, please, put the file into another location, and give us a new link? This is dead.
Thanks.

P.S. Sorry for errors in English - it's not my native language...

Spent a lot more time trying to get this working than I care to admit, however I finally got it running and would just like to say thank you!

R9-280x - 23Mh/s

1090Mhz Clock
Stock Memory Clock
0% Power Limit

My only question is that I was never able to find a working download link for your .cl file, I just replaced the .bin file with that from Wolf. Not sure if I would get better results having your .cl file as well but if anyone can provide a working link to that, it would be most appreciated. Given my confusion on how to get started, here is what I did in case anyone else runs into the same problem.

1) Download SPH SG-Miner
2) Run it and connect it to a pool, where it will generate a .bin file in the root folder of the Miner
3) Download Wolf's Tahiti Binary (https://ottrbutt.com/miner/wolf-groestlcoinTahitigw256l4.bin)
4) Place the Binary file into the root folder of the Miner, rename it to that of the one in Step 2 and delete or replace the original

Another question I have is if I can solo mine using this?
