Asus R9 290 problems with Intensity

[PDcologne]

Hi guys - so im having issues...

i decided to build another rig this time using Asus 290's not X.

i have built many many rigs based on 280x with not many issues but this time im stumped.

so 3 x Asus 290 all being detected as i would expect running via windows 7 64bit in cgminer 3.7.2

i came to write the BAT file and the issues start, as soon as i enter an intensity number over stock( i get HW errors galore.

Everyone seems to be running these cards at 20 with no problems....

if i run without an intensity number specified everything runs fine... everything else is tweaked.

problem is it is only hashing at 30kh/s or something like that...

ideas?

full spec

3 x Asus r9 290
asrock MB - fatal1ty z77
80+ platinum PSU 1200w
6GB ram
intel something processor
windows 7
cgminer 3.7.2
drivers 13.2 suite - i thought this could be my problem, but have used this fine on every build i have done

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

add these flags to the first line of your .bat file and report back

hi thanks for the reply - maybe i should have added a config...

the info you have provided is standard in my configs, as i said i have built many rigs - but this is the first time i have had any real problems.

Have you tried lower TC like 24550?
