R9 R290, Catalyst 13.12, Powertune +20%, [email protected] and [email protected] with Linux-v0.1.4 running -a 0, two threads per GPU and no other load. So far, no one was able to reproduce this in Windows but it should be possible because even a 280X easily hits more than 2700cpm. Still wondering because yesterday a user with 2 R9 290X reported only about 6100 cpm.
Can I ask what you are using a version of the LINUX it?
I am using UBUNTU DESKTOP version
Only recognizes a GPU, only 2300C / M ,with 3800C/M so long way
Will there under LINUX how to modify the GPU CLOCK, MEM CLOCK, GPU fans

I am getting 6830 col/m on 5x Sapphire 7950 with stock settings. That is ~1370 col/m. I have Celeron with 4Gb Ram.

Does anybody knows, how to tweak performance to get closer to 1800 col/m as some users are reporting.

I am using Ubuntu 13.1 with the latest drivers and miner v0.1.3.
Please use v0.1.2 until the next version is released. This should be fastest on your GPU. I'm working on an update with huge performance gains.

v. 0.1.2 with some tweaks I managed to squeeze out 7250 col /m
v. 0.1.4 I am  getting 9300col/m whoa

Slightly decreasing memory clock and increasing engine clock, using  algorithm 1, I managed to increase speed to 10500. Whooha!

well thats interesting, decreasing memory mhz actually was a benefit? what were your stock settings and what did you adjust to? wondering if there is a magical percentage point between the two like when mining some other coins... usually I end up cranking the memory to max and adjusting engine after that...

I tested on Gentoo. The command line tool to modify frequencies is aticonfig, which should work after enabling AMD Overdrive (see --help). How many GPUs do you have? For one GPU I would use -t 0,0 and for two -t 0,0,1,1 etc.

Sorry for the confusion. It seems that I got benefit by increasing engine clock. Reducing memory clock did not increase col/m. But it has slightly reduced temp. As I don't have watt meter, I was a bit conservative with setting.
Main drivers of increased speed are algorithm and engine clock.

I run clpts2.2 on a centos6 box, got the following messages:
Code: [Select]
%./clpts
./clpts: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory

would you please compile the program statically?

Sorry, that is caused by a dirty Makefile. I will upload a new version in a few minutes
EDIT: Done.

My card:
270x 1450   -a 1
280x 2450   -a 1
290 2600?   -a 1(-a others is slower)

all cards not overclocked,seems 290 too low, is there some special setting need for 290?

I released a new version with large performance improvements. The syntax of the command line options of v0.1.x has changed and one has to specify the device IDs like in v0.2.x (see README). Furthermore, the command line option -a was introduced to select an algorithm. I guess that -a 0 or -a 2 should be fastest on R9 290(X) and -a 1 or -a 3 should be best for non-R9 290(X) cards.

Sometime within the next couple days I'm going to give Gentoo (or another distro) a try and see if I get any performance improvements.

Currently - 290X (1150Mhz/1375Mhz) - ~3200 cpm on Win7.64

I have a 6 GPUS, use-T 0,1,2,3,4,5 but only GPU 0 at work, I still do not understand how, under LINUX for GPU overclocking

Maybe your Xorg.conf is screwed. Run aticonfig --initial --adapter=all as root and restart the computer.

i have a question.

how old is "too old" for the drivers. 12.8 too old?

also, my cards are:

rig1:
7950
5970
12.8 drivers
win7 x64

rig2:
7870
12.8 drivers
win7 x64

rig3:
270x
14.1 drivers
win7 x64

will this miner work with all 3 setups?

I fear that you have to try it yourself. catalyst 12.4 is too old. Could you give a feedback whether catalyst 12.8 works?

thank for your good works NAN  ;D

I have better performance with -a 1 on my 290s (+100 cpm for 5*r9-290)


Continue , i love your miner :)

Thank for your miner

win7 x64
ASUS 280X 1125/1500 use two threads and -a 1 , 3280CPM
ASUS R9 290nonX(reference) 1025/1250 use two threads -a 0 only 2900CPM , why?
