try using xIntensity in CGMiner 3.7.3 or SGMiner 4.1.0

intensity is a direct multipier. meaning.

Int   Threads
13   8192
14   16384
15   32768
16   65536
17   131072
18   262144
19   524288
20   1048576


the jump at 20 basically overloads the cards.

using xInt allows you to tune it because its a nuliplier of your shader count. The 290 has a shader count of 2560. so an equivilent Xint in comparison to Int 19 is

Int   Threads
19   524288

524288 / 2560 = 204.8.

i currently have mine at an xInt of 256 as it a nice mulitplier of 4.

xInt   Threads
256   655360

good luck!

Also, as a reminder, your thread concurrency is usually best at a multiplier of your shader count  plus 1 so 2560*N+1 mine currently set at a mulitplier of 12. (2560*12+1) = 30721.

Post your config here.

But regardless, since you used to handle 280x I'd venture to guess you're using -g 2 ?  If that's the case than R9 290 are using -g 1 and with that you can also increase the TC (20481, 24500, 32765 works for most pretty well).

Hi, thanks for the reply.

I have actually stripped back the entire config to realise it was the intensity causing the issues...

but i had already changed the -g 1 after spending the last few hours on google trying to fix this before posting here...

my config is purely stock right now - its simply when i change the intensity it goes crazy - stock intensity is 8 - even trying the 280x "normal" of 13 causes issues so you can imagine what happens when i go -I 20  Shocked

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(Cool 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
