Im wanting to bring my 290 rig back to utc, can someone let me know the current tc and i settings please. 
Depends upon system RAM..
8GB RAM go for TC 42000, I 18
4GB RAM - I use the same with a lookup gap of 3, others have success with gpu threads 2, tc 21000 and lower I
thanks for that, im getting no hardware errors now and im hashing at 185khs is that about right?
whats your setting for 185kh/s? i can get max 180 kh/s which is not stable
Im using the stilts bios with default settings 1000 engine 1375 memclock way undervolted
