R9 290 Tri-x OC hanging issues

[romiferns]

Hi everyone,


Mobo       : Gigabyte
Processor : i3
Ram        : 16Gb
psu         : corsair 850w

i am facing issues trying to increase the hashrate of my r9 290 tri-x graphic card.  I have installed the 13.12 drivers and amd app sdk 2.9.  My miner settings are

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer --scrypt -o poolname -u username -p password -I 13 --worksize 256 -g 2 --thread-concurrency 20480

the max i can get is 530khps. it starts to hang if i try to increase the intensity.

hey,

me using the same card but getting 835KH avg. Use the settings below which i have for my miner.

cgminer --scrypt -o poolname -u username -p password --thread concurrency 25500 -I 20

Hope this helps.

the pc crashes if i try -I 20 the max thread concurrency i can use is 20480 and i 13.  i have tried every procedure on the net but it just wont work. dont know if the monitor has to be connected directly to the graphic card coz i can see the fans rotating even if im not mining.

have you tried to disable Audio, USB 3.0 from BIOS, try that.. it will also save Power.

What is the OS which your Using, if Win 7 try and disable AERO and check.. i am using the same card but on a AMD Processor(this should not matter)

your worksize is wrong.it must be 512

[jaideep1000]

try running without the worksize and thread concurrency tags.
Let cgminer autoadjust and then see what hashrate you are getting.

Have you tried these settings ?

Code:

-I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20

Have you tried these settings ?

Code:

-I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20

those are the setting for R9 280x. we are talking here about R9-290
