^ WOW! That's cool! Thanks for the support, guys!

Yeah are hot, but at core clock 1140 ?!

A very interesting remark. The very same card was unable to speed up more than 1050 for core - when mining Scrypt. After going to Groestl - mem clock was downed to 1000 - the card became much cooler.

And then was easier to speed up the core clock.

Voltage on 12V rail was dropped from 12.7V to 12.02V under Groestl load  - so still within specs.
Under scrypt the voltage dropped to 11.92V - slightly under load.

Now after this new AMD driver - the card became slightly hotter, it is using 25W more - and the hash rate increased for 80%.

At least part of the AMD driver update was improved OpenCL compiler.
I took the .bin file from my Windows machine and copied it to my BAMT machine (note, it is better to perform the driver update procedure from previous page, if you are no afraid of doing that).

I did not update the driver, just copied the .bin file generated on Windows 14.6 beta into Bamt with 13.12 drivers.
And here's what I'm getting for my 2X R9 290 Tri-X:



(used to be 9.5 MHS)

Please post your new AMD hashrates to the spreadsheet: https://docs.google.com/spreadsheets/d/1hTOUdJZrKqrNDXTIbXgNvJtj_fnpECREcs-eHxaGrZc/edit#gid=0

Same for Android miners

[roushonul]

I am getting 14 Mh/s from my tri-x r9 290 on 1080 gpu clock but for better stability fall back to its reference clock. getting 11+ now. In r9 270 Non X I am getting 6+ Mh/s on 1050 gpu clock. But most exciting thing is I am doing solo mining and my 2 rig point on one wallet and speed of 2 rig combined is 52 Mh/s(I swear I will make it 5 Mh/s more. Just tired). In this speed in pool mining I should get 1600 coin and I already found 3 block in first 7 Hour. Been lucky. Hope luck will remain but also fun on setup(No specific tutorial for GroestlCoin. I set it up based on litecoin. Fun is there). Happy mining.

1080 may be a bit too high.

Try 1050. I have 4 TriX running at 1050 for days, no problems

Could you please post the updated sgminer with updated .CLs?

sgminer have not been updated
.cl files have not been updated

this is purely a AMD driver issue. Update the driver and you'll get better speed.

is the new wallet available for miners?

[srcxxx]

I was not able to update the driver.

http://rumorscity.com/2013/12/08/amd-display-driver-update-for-r9-290x-on-bamt-litecoin-miner/

The 1st step (uninstall the driver) fails for me. After I do coldreboot, the BAMT is unoperational. Cannot even start terminal. Says something about permissions.

Has anyone been able to update BAMT to 14.6?

PS: I also tried without uninstalling the previous driver. In such case, the installer just says not enough disk space to install. :-(

Thanks

^ now THAT would, indeed, be great news! Can any other miners confirm this?

Listen guys, I have checked this and new drivers ARE A TRUE POISON. At least when Groestlcoin is in question THE SPEED OF HASHING IS ALMOST DUPLICATED!

On R9 280x my previous hash rate was 6.8 MH/s. Now it's 11.43 MH/s.

Fans on the card are not cranking - but rather wheezing with a very high pitch and started to radiate a serious heat. Who says Groestl is friendly to the cards...

How to achieve this result:

1. Get yourself BAMT 1.6.0 (or any other 32-bit Linux distro will do):

http://www.reddit.com/r/BAMT/comments/207rdz/release_bamt_v160_scrypt_scryptn_darkcoin/

2. Get yourself a decent sgminer-sph, I am using this one:

https://github.com/badman74/sph-sgminer

3. Get yourself the latest AMD 14.6 drivers, files are the follows:
linux-amd-catalyst-14.6-beta-v1.0-may23.zip
AMD-APP-SDK-v2.9-lnx32.tgz
ADL_SDK.zip

4. Now, uninstall old drivers, reinstall new drivers, RECOMPILE THE SGMINER:

The EXACT procedure is noted here:
http://rumorscity.com/2013/12/08/amd-display-driver-update-for-r9-290x-on-bamt-litecoin-miner/

NOTE:  Please follow the procedure EXACTLY.

5. DELETE the old compiled CL file, which is usually hidden here:
/opt/miners/sgminer-4.1.0-sph

NOTE: The key to enhanced performance is hidden in NEW on-the-fly re-compilation of .cl files.

6. Everything else is as usual. Mine cards speeds up to 11.43 MH/s:

7. Parameters I am using:
  core_speed_0: 300
  core_speed_1: 1140
  core_speed_2: 1140
  mem_speed_0: 300
  mem_speed_1: 1000
  mem_speed_2: 1000
  core_voltage_0: 1.131
  core_voltage_1: 1.131
  core_voltage_2: 1.131

8. Config file I am using (partial print):
    "auto-fan" : true,
    "gpu-fan": "30-99",
    "temp-cutoff" : "95",
    "temp-overheat" : "85",

is the new wallet available for miners?

Of course!

Hardfork is in 3 hours, make sure you are using wallet 2.1.0.6!!!

Faucet and RPS game ready and updated

[pregoRI]

any other advisory, about the hardfork ?

any other advisory, about the hardfork ?

Don't move a lot of money some time before and some time after any fork, not just Groestlcoin.

If sending GRS to exchange, use a small amount first to see that it worked.

PS: Forking is now complete. Block count is 120,005.

These are commands to uninstall the driver:
apt-get update
/usr/share/ati/fglrx-uninstall.sh --force
coldreboot

You have to execute them as root. Without uninstalling them first - you will get a mess. Start from fresh BAMT installation and repeat the procedure.

type of WIN ?

I change drivers to 14.6, same hasharate

try to delete the Bin file.

Awesome!!!! 7950, from 5,4 Mhs to 9,1 Mhs , 1050 core

Power consuption from 520W (complete rig + 4x7950) to 595W

how did you do it? my 7950 cards don't want 6.3Mh above :-( show config

[FiR3]

NoxX: (30%*14.4)+14.4=18.72, !14.6

I meant going from driver 14.4 to beta driver 14.6 does not change the hashrate I get for my cards ^^

But I never used driver version 13.x, so not sure about the differences there...

Sorry, my misunderstanding

[ocminer]

suprnova.cc is on wrong fork. I've notified the operator once again and the problem should hopefully be fixed shortly.

Other pools seem to be operating fine.

updated to latest wallet now, did not get any info that an update was needed again, sorry !
