Topic: R9 290 problem please help (Read 829 times)

A 290 should have 2560 shaders if it is not unlocked.  Try setting TC to multiples or half multiples of that to avoid HW...IDK how people come up with TC numbers, but I know this works on all my Linux rigs.  My 290 is at TC 40960 I 20.

I will try this before resting everything when I get home.

Thanks

I will try this as soon as I can and I will let you know, I hope it helps also if I set intensity from 13 to 14 it starts getting a lot of HW.

thanks

my clock speeds are 1500mem 980core with no under or over volting

Try this

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o STRATUM -u WORKER -p PASS --thread-concurrency 24500 -I 18 -g 1 -w 512 --gpu-fan 70 --lookup-gap 2 --gpu-engine 947 --gpu-memclock 1250 --gpu-powertune 20

What were your clock speeds?

might be of help, my cards are all 290x version and they are each different brands(asus,xfx, ect ect)
When i first started the rig with each card i could never go over 8192 for TC after 2 days of wtf i finally striped the rig down and formated my ssd and reinstalled fresh windows 8. updated all drivers and made sure my bios was gtg then ONLY installed what i needed: amd drivers, amd sdk, cgminer 3.5, cgwatcher ect ect. i also installed google chrome but thats because internet explorer sucks. after that i was able to increase my TC to 32768 with intensity 20 and got 950k/hs each card with no issues, i ended up turning down intensity to 19 an only lost 75k/hs overall which isnt bad to not fully maximize my cards, makes me feel better if nothing else but anyways. if you can i would backup what you need format you HD or get a fresh HD and do an install of OS of your choice then see if that changes anything. i know it seems like alot but worth a shot if you have 3 hours to kill to do everything. word of advice i learned was before i did all that i downloaded all drivers for the mobo, amd ect ect put them on a pin drive that way once i was finished with windows i just put the pin drive in and when down my list and installed reboot repeat till they were all done. hopefully this helps you out some.

Anyone please?

Hi

I bought 2 r9 290 a few weeks ago and I can only get 510 kh/s if I set my intensity above 13 I start getting a lot of HW also if I get my TC above 8192 I get a error 04 gpu failure.

Please help

thanks
