The monster below recently started mining on the pool, this guy has to have over 1mill c/m.

@lir111: What are your command line options?

Ouch meaning what? Sucked he had to have someone else fix it? Or that 14.1 drivers suck?

No, "ouch" because AMD f***ed it up. I hoped that those times were over... That is not the only problem with the Catalyst drivers (e.g. the 290(X) performance inconsistency in Windows and Linux)

I so hope the Windows issue is resolved for the 290x's.  Not sure how long I can stomach Linux's lack of undervolting/clocking tools for these cards.  I can't even see what voltage my cards are running at...

Has anyone tried mining with the 14.1 drivers on windows with the 290x's?

I've been reluctant to try the 14.1 drivers because of the significant performance impacts seen with scrypt miners.  I know my performance on the ASUS R9-290XOC is crap (550KH/s) compared to where it should be.

In clpts I'm getting around 3250c/m with the R9-290X under Windows 8.1 and the 13.x AMD drivers.

How much better is it under Linux?

~4000cpm stock and ~4500 cpm with OC.

how to set the fan speed to 100%? with multiple GPU Fan speed? @ubuntu 12.04

Hint : cgminer..... aticonfig does NOT work under linux with more than one GPU

It works, just use the following.

export DISPLAY=:0
aticonfig --pplib-cmd "set fanspeed 0 100"

export DISPLAY=:0.1
aticonfig --pplib-cmd "set fanspeed 0 100"

"export DISPLAY=:0.X" --> Change X to whatever GPU you want to change the fan speed on.

Would this work for overclocking cards like 270's with aticonfig?

I still don't have a proper method for undervolting on Linux. I use the following to overclock core and memory.

aticonfig --adapter=0 --od-setclocks=1140,1500

just change adapter number for different GPU's, also [Core, Memory]

I need some help setting up my miner. I have my 290 on the Ubuntu machine. Can someone help me set it up? I don't know the commands to get it running in as I am very new to Ubuntu. Still learning the process and terminal. Can someone help me?

Change directory to the folder containing the miner files.

chmod u+x ./clpts

For Be^5r -> ./clpts <address> -t 0,0

For YPool -> ./clpts -u <username>.<worker> -p <workerpassword>

I apologize if this was all the information you needed. Starting up the miner is the easy part. I was assuming that you
just installed Ubuntu and you haven't installed the AMD catalyst drivers and assured that xorg.conf was setup correctly
(which is kind of the pain in the neck part). If you have 'aticonfig --list-adapters' working and reporting all your GPU's
then you're pretty much good to go!

I read it from a different perspective lol, I assumed he had his drivers set up...If he does then he should be able to just use those commands.

I found this guide on editing your bios to undervolt AMD GPU's on linux. Someone should give it a try and share your results, of course know that this is at your own risk. I am extremely busy with my work and school schedule so I most likely won't get to it this week.

No problem! Actually I managed to snag another MSI R9 290 from NewEgg earlier this
week and it came in yesterday. Yeah, the price gouging is getting rough as I paid $25
more for this single one than I did the other 4 from the same seller! I also got rid of
the 20" box fan and purchased 4 200mm 110 cfm fans to lower the noise level.

So now the rig is as follows:

5 x MSI R9 290 running Ubuntu 13.04 & clpts v0.2.2.
Currently mining on Ypool at the moment and getting :

collisions/min : 18908
shares/hr : 2192

The total rig is pulling 1300w.

Nice!! Thanks for the info. I'm thinking of buying a couple R9 290 if I can't find any cheap 290X. The problem is that even R9 290 are in the $600 range......

Yea I got lucky and I managed to get these 4x R9 290X for $599 ea off Amazon.

Aside from my 4x R9 290X I have 3 GTX 780 which are pulling a measly 6500 cpm together....I bought those last year before I planned on mining. *shrug*

Now I'm just creeping around Amazon, Newegg, Tigerdirect, and Ebay until i find some rightly priced R9 290(x).

Edit: What temp are your cards running at? I just bought some 1x to 16x powered PCIE adapters and I think I'm going to pull out all but one of my GPU(s) from the case. The second card is making my top card run at 80C - 85C at all times with Fans @ 100%.....while second card stays at 60C-65C.

My rig has 4 x R9 290's (soon to be 5 x R9 290's when I get home) and since
switching to Linux yesterday the multiple threads work great for that little *oomph*
in computing power. Another way to look at my unique idea is to run certain GPUs
(multiple thread) on Ypool and then run the remaining GPUs (multiple thread) on
Beeeer, essentially devoting a GPU card to a pool. This is great for those with even
amount of GPU cards which I will NOT have when my fifth arrives today....

Just thinking out loud.... :-)

@mbender71: I've never tried that because I always tested with a multiple GPU setup. But I think it should work.

What is your cpm with 4 R9 290?

Has anyone successfully set the GPU voltage using cgminer under linux for a R9 290(X)?
I have my gpu clock, memory, and fan settings where I want them to be but I wouldn't
mind under-volting the GPU to save a little energy and heat. I *believe* cgminer wants
an exact voltage and not a delta but I could be wrong. I don't know what the normal
voltage is for a R9 290 and every attempt to enter an absolute value like 1.25 fails (out
of boundary). Many thanks in advance!

I have been in that same situation for the last two days. I found some good clocks that provide a rather good performance boost in-terms of c/m. I have my 290X's running at 1150/1150. The core increase raised my c/m by ~400, the problem is that I am having some heating issues (80C - 85C - 90C spikes)...I'll try to figure out a way to undervolt on linux, I'll post my solution here if I find anything. If you find something please share.

At the moment I have multiple .sh files that I execute after a system reboot. One sets the fan speed to 100%, and then overclocks my GPUs, one to initialize the miner, and the last one to monitor temps.

Edit: I found this http://sourceforge.net/projects/amdovdrvctrl/?source=navbar, I'll give it a try once I get home. It was last update Dec 13 2013.
