Here is the fun part:
I have3 R9 290 in 2 different rig that always loos 0.2 MHs after 10 minutes, no matter what overclocking I gave to them.
BUT: the cards looses their MHS at the exact same second...I tried several reboot and look at my screen during a few minutes: It's stable for a while, then after a few minutes, at the exact same seconds, my 2 cards loose 0.2Mhs.

I'll give it a try. By the way can you tell me wich excact Linux version you used with your 290?
Should I do a git clone ./autogen.sh ./configure make?
It said download and extract...
Once I got that installed, I launched it using od6config --list for example, no funky move of chmod of any sort? (I'm a total noob in Linux)

I still need advice for R9 290. My cards looses 9% hashrate after 10 minutes on 2 rigs.
If it did not, please tell me what system you use and I gave it a test (bamt1.2, 1.3, 1.5...)
If you have some ideas or some tests I could do, you're welcome too.

I've modified a SMOS scrypt to autoinstall this miner in /opt/miners/sgminer For those interested : #!/bin/sh mine stop wget http://smos-linux.org/upgrade/sgminer.plwget http://smos-linux.org/upgrade/sgminer2.plrm -rf /opt/bamt/gpumon mv sgminer2.pl /opt/bamt/gpumon rm -rf /opt/bamt/common.pl mv sgminer.pl /opt/bamt/common.pl sleep 5 cd /opt/miners/ rm -rf sgminer git clone https://github.com/prettyhatemachine/sph-sgminermv /opt/miners/sph-sgminer /opt/miners/sgminer cp /opt/ADL/include/* /opt/miners/sgminer/ADL_SDK/ cd /opt/miners/sgminer/ ./autogen.sh sleep 5 make clean sleep 5 CFLAGS="-O2 -Wall -march=native -I /opt/AMDAPP/include/" LDFLAGS="-L/opt/AMDAPP/lib/x86" ./configure --enable-scrypt --enable-opencl --bindir="/opt/miners/sgminer" --prefix="/usr/local/bin" sleep 5 make sleep 5 rm -rf /root/sgminer.sh clear echo "sgminer 4.0.0 installed." echo "SMOS-Linux.org" echo "Now reboot your rig, and start mining" If you're on SMOS or BAMT it works perfectly. LOL, just got ready with my own SMOS image with sph-miner.  After updating to lastest SMOS, I've about 2.2Mh/s on the r9-280x cards. On what BMAT ar yo with your 290 to have 2.4M ? it seems to matters if I listen to your experience. |

...Fed up with all this...
I build a new rig, I started with 2.4 and 2.2 on my 2 cards. 10 minutes later I have a 0.2 drop on each card and ended with 2.2 and 2.0.
What's happening? 2 different motherboards, 3 different 290 cards, and always the same 0.2MH drop after 10 minutes. I coldreboot? I get my 0.2 back. 10 minutes later it starts over.
I gave 10 Darkcoin to people that can solve my Problem

I really can't manage to have stable mining with my 290: started at 2.4, and 30 min later I'm at 2.1 with memory switching between 1500 and 150mhs.
It does this with all my cards, someone fixed this with a bios modification or custom memory tweak?
Are you undervolting your cards? I had mine undervolted for mining scrypt, but with X11 (Darkcoin) the undervolting caused my cards to be unstable. Undervolding isn't needed either as they run much cooler anyhow. No Im' not, since I can't edit the 290 bios. After each test I got the same conclusion: I reboot and got a 2.5 hash, then 10 minutes later it falls to 2.3. No matter the parameters, I got a 0.2 drop of the hashrate after 10 minutes. The only way to get them back is to reboot my computer (not relaunching the miner). It's 9% of the Hashrate that is lost...I'll be glad to do something with it... |

I have 13.12
I use vertminer BAMT 1.52
I really did not understand my 0.2M drop after 10 minutes on my 290...it's a 9% drop...

my sgminer works well but when I use this one with my .conf file, it's doesn't take gpu & mem clocks.
Any idea ?
have you compiled it with ADL? Do you see the GPU temperature? If it's like me he spoke about the windows build |

My rig with bamt with my 280X run well with 2.1M per card undervolted. 1050/1500
My rig with bamt does not run well with 2.3M per card. (2.5 then 2.3 after 10 min)

The windows link in the first post did not work at home.
I got kernel is experimental, then a black screen is loading, then nothing.

Nop, I'll try that.
The best miner is the one listed on the first post, or there is one update somewhere else?
For Windows and Linux Bamt.

Here are my parameters.
The first card is the 290.
The temperature is 63°.

Thanks, both of you.
Interesting to see totaly different settings.
You use the Sph-sgminer of the op?
I use it on bamt, and I think I found my stability problem: with intensity 21, after 5 minutes, my hashrate decrease quickly. So I'm surprised you are stable with such high intensity (classic intensity?)
I managed to reach 2.5 using intensity 20, but 1120 gpu-engine, not sure if my card will not fall Sick.
Does the thread concurrency matters for that currency? I did not put anything in my configuration file.
I just noticed my Hash went from 2.5 to 2.3 after 10 minutes...so same 0.2 drop again, I really don't understand where it came from.

Hi!
I'm only getting 1.24Mh/s on the Sapphire r9-280x, I guess it should be a little more, with my R9-290 I get ~2.5Mh/s.
Thats my current config:
--shaders 2048 -I 23 -g 2 --thread-concurrency 16374 --lookup-gap 2 -w 256 --auto-fan --gpu-fan 80-100 --gpu-powertune 2 --gpu-engine 1100 --gpu-memclock 1250
any suggestions how to tweak this?
Theses are your 290 settings? Your 290 is stable at 2.5, even after an hour of mining? |
|

My config is with intensity 21, 1 thread, and memclock 1500

I need some help with 290 cards.
I always started well with 2.4M hash, then after a few minutes, it starts decreasing slowly, all the way tl 2.1M.
It did that on all my 290, and just on my 290s: on my 280 I have some stable 2.1M from the beginning to the end.
I first suspected it was some sort of bios issue, but I got the same with a custom bios.
Any-one have a stable mining with a 290 that last a few hours above 2.4M?

Is there any mining calculator for darkcoin?
I wish we could be on coinwarz but they only have scrypt and sha-256 But though I don't know of a calculator, I can offer you this formula: Your hash rate = not enough coins  It's pretty much true for everyone  This formula working for you? Not really, it just shows me that I'm turning into an @ss which means it's time for bed, LOL Waiting for my graphics driver to install on my laptop, and it's taking forever! TanteStefana, you make this thread so much more enjoyable to read. @avanda, I don't know of a mining calculator, but the official pool gives this payout estimation at the current difficulty: kh/s: 50,499 drk/day: 81.416 You can extrapolate from there. Around 1.6 DRK / kh / day. So profitability seems to be less than 70% of multipools I don't understand that actual price then  |

Are you stable? No drop after a while? No memory withc toggle between 150 and 1500?
I suspect a bios issue, but I can't really tweak it since VBE7 doesn't work.

This is settings for 280x, not 290.
The point is with 290 you got the same result thant with a 280, so you better mine something else.
At home I mine at 2.4 and half an hour later, I'm back at 2.1 because the memory switch to 150 instead of 1500.
