Need help mining effectively with R9 290x

[typesblur]

Hey everyone,

I'm having some issues getting my Asus R9 290x to run at optimal settings.  With no arguments after --scrypt I was only able to reach 20 Kh/s.  But after many hours of head scratching and face smashing, I created a code that allowed me to up my hash rate to about 535 Kh/s after OC. Clock 1025, Mem Clock 1500 Powertune +20. (see below)

CGminer 3.7.2 with latest catalyst drivers and SDK installs

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer.exe  --gpu-platform 0  --scrypt  -o stratum+tcp://XXXXXXXX -u XXXXXX -p XXXXXXX -I 13 -w 512 --gpu-powertune 20 -g 1 --thread-concurrency 8192

Anything over I 13 I get HW errors left and right.

I see everyone else with this card running at 700+ and I cant figure out how to bump my TC or I higher without crashing.  If I bump my TC up to anything that I find on the litecoin hardware comparison chart (or anything higher then 8192), I get error -61 stating I need to lower TC or increase LG.


Hardware List:
16GB corsair DDR3 1600 (PC3 12800)
Asus R9 290x
ASUS P8Z77-V PREMIUM MB
Corsair 850W PSU
SSD (16gb data free if that means anything)
Win 7 64 bit

Thank you for all your help in advance!

Hi

That seems very low for 290's my 280's get 710Kh/s here is a copy of my cgminer config for my R9 280's I think you have some setting missing that might help 

./cgminer --scrypt -o stratum+tcp://xxx.xxx.xxx3334 -u user -p pass  --lookup-gap 2 --thread-concurrency 8192 -g 2 -I 13 -w 256 --gpu-fan 95 --temp-cutoff 90 --temp-overheat 85 --temp-target 78 --gpu-memclock 1500 --gpu-engine 1000 --gpu-powertune 0 --shaders 2048 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

Tried your code with no improvement. I also changed the #'s to match the 290 but still no change in hash rate.

Hopefully I can get it fixed soon but in the meantime something is better then nothing!

Thanks for the help Hinrg

I´d give a try lowering core/memory clocks and trying to increase TC and intensity.
