Looks like drivers 13.12 are better for R9 280X.
See post https://bitcointalksearch.org/topic/m.7339919 above
Probably because R9 280X is just a rebranded 7970. So it is using some old AMD designs.

New models like R9 290 and R9 270X definitely work faster on 14.6 drivers.

This is when the compiled binaries become interesting (see above).

Nice work srcxxx! My 7990 is now running at 13.4 mhs per core running with auto-gpu. Only had 6.4 mhs p/c before. More heat now though!

Sorry should have made that clearer. I'm running on R9 280x. I lost half a day installing those dam drivers to end up installing the previous one. 14.6 did nothing good for me.

srcxxx, may I suggest you remove the thread concurrency (and lookup gap, and vectors...) from the filename, so the files are ok for everyone, regardless?
I did this myself in sph-sgminer in the past, it's much convenient. The only downside is it's not compatible with scrypt.
I can provide details if you wish.

Optimized kernel binaries are now available! See first post.

Extra hashrate for supported video cards.

If you could provide name/model of video card, it would be great.

Looks like R9 280X works faster with older drivers.

While R9 290 and R9 270X definitely work better with 14.6.

It'd be nice to have some kind of list and I'm planning to do this.

What's important is that you can compile .bin files with one version of drivers and use the miner in another version of drivers.

I myself use BAMT and it has 13.12 drivers. But the .bin files that I compiled on Windows 14.6 work 80% faster.

I'm on Xubuntu 12.04. Updated drivers to 14.6. I lost hashing power. Reverted to pevious drivers.

You are mining diamond coin but haven't supplied the normal-hashing parameter. See 1st post in this topic.

You need to add --normal-hashing to your command line.

.bat file:
sgminer.exe -k groestlcoin -o stratum+tcp://dmdpool.digsys.bg:3333 -u login -p pass --gpu-engine 1170 --gpu-memclock 1050 --thread-concurrency 16384 -I 22

Supposed to be 12 mh/s

No, x11mod Didn't work for me on r9 290. HW errors only

Please provide more details. Config/command line, screenshot of sgminer or printout. What's the rejection reason? Share below target?

If your sgminer tried to submit the share, it means hashing is working fine.
If you had a 100% hardware error rate, then it would mean it is not working.

Are you mining ATH on suprnova by any chance?

Thanks

Doesn't seem to work with the last generation of AMD cards. I only get rejects on HD 5xxx cards... DMD  
work on Groestlcoin 6 Mh/s   HD5850
 

Doesn't seem to work with the last generation of AMD cards. I only get rejects on HD 5xxx cards...

with 7950 not working only rejections

How does this perform with 280x? Any stats?

well done
thx for ur effort!

Does x11mod work with 14.6 now?

grs-sgminer is a OpenCL optimized miner for coins using Groestl and MyriadGroestl algo (Groestlcoin, Diamond, Myriadcoin, Saffroncoin, etc).

Notice: cryptohunger.com:81 and grs-sgminer are going to be retired on 31 October 2014. Please migrate to boostpool.com before 30 September See details here.

Note: boostpool.com with auto payouts in BTC and GRS is currently in Beta (official release date: 22 September). No exchange fee until 22 September and BTC payouts are allowed (just use your BTC address to log in instead of GRS address). Details: boostpool.com BoostPool now has a separate BTC talk page.

Speed with Groestl mining:

R9 290 - 20.5 MH/s (14.4MH/s if using standard sph-sgminer with 14.6 beta AMD drivers and 9.5MH/s on drivers prior to 14.6)
R9 270X - 10 MH/s
R9 280X - 16 MH/s (some only report 12MH/s, see details below. Probably you need 13.12 driver)

Speed with Myriad-Groestl (Myriadcoin, Saffroncoin, Futurecoin) mining:

R9 290 - 34.2 MH/s

Version 1.4.0 (17 August 2014)
* Windows build
* switch between Groestlcoin and Myriadcoin-groestl on the fly without restarding the miner
* 5% more hashrate in optimized kernel

Version 1.3.1 (10 July 2014)
* Added support for a wide range of AMD videocards (more .bop files in the package)
* packed with 7zip now (http://http://www.7-zip.org/)

Version 1.3.0 (7 July 2014)
* Added myriadcoin groestl support (see example-myriad.conf)
* Removed "l4" suffix from .bop filenames

Version 1.2.5 (25 June 2014)
* Added R9 290 optimized Kernel for Tahiti, Pitcairn and Hawaii GPUs
* Shows a warning if "optimized" kernel is used with incorrect pool



* BAMT setup instructions (see step "6a").

*** Example command line ***
Groestlcoin (20.5 MH/s on R9 290): sgminer.exe -k optimized -o stratum+tcp://cryptohunger.com:50001 -u FnzMEE2fkX31J5EjheNMo8pq2672Q5kjGh -p xxx -I 22 -w 256

Myriadcoin (34.2 MH/s on R9 290): sgminer.exe -k myriadcoin-optimized -o stratum+tcp://cryptohunger.com:60001 -u MUbwYW4NmmkR4Ejg5v7tQye5DW5jSQVz3X -p xxx -I 22 -w 256

Diamondcoin (20.5 MH/s on R9 290): sgminer.exe -k optimized -o stratum+tcp://cryptohunger.com:50002 -u dSwcxqXiYrZehaiy6sKfQv1NyEtxTXrmrz -p xxx -I 22 -w 256 --normal-hashing true


*** Release highlights ***
* Built-in Diamondcoin support (via a "normal-hashing" per-pool parameter, see example.conf)
* Automatically sets proper difficulty multiplier (not required to write --difficulty-multiplier 0.0039062500 anymore)
* thread-concurrency and lookup-gap parameters are not used anymore
* Added "optimized" kernel, see below

Attention Diamondcoin miners:
* You need to specify --normal-hashing true parameter on the command line or in the .conf file (see example.conf)

!!! Optimized kernel binaries (about 5%-25% better hashrate than if you don't use them) !!!
You need to use "-k optimized" instead of "-k groestlcoin" in command line parameters.

Note: "optimized" kernel only works with these stratums:
   {

They do not work with any other pools. They do not work with cryptohunger.com:3333 either. You'll get HW errors and no accepted shares.
See statistics here: http://cryptohunger.com:81. Payouts every hour. Just use your wallet as login.

Please use https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit?usp=sharing to fill in your "Groestl" parameters.

Note: With Groestl and Myriad Groestl algorithms, you usually can overclock GPU quite significally. For example, I'm using 1170Mhz on R9 290 (where standard frequency is 1000Mhz).
This happens because these algorithms don't use power hungry memory exchange operations and thus GPU produces less heat and stays within TDP bounds.

Make sure you are using 14.6 AMD drivers for R9 290 and R9 270X. And make sure your are using 13.12 drivers for R9 280X (other driver versions give lower hashrate).
Note: you can compile .bin files in with one version of drivers and execute miner while another version is installed.



Notice: OpenCL source code for optimized groestl kernel is not open source.
I am ready to exclusively sell the source code and the cryptohunger.com pool for 10 BTC (opensource or keep to yourself the kernel; use the pool or close it and be the only one using the optimized kernel).
