I am also having trouble with my 280x. It runs in the 360 h/s range like the poster said before me.
Here are my specs
16gb ram
i7 4770k
msi 280x
For whatever reason I cannot get this to hash at 450 yet. If anyone solves this please let me know. I am still working on it myself and if i come up with anything I will share my findings.
mines run around 350 h/s with 280x
catalyst 13.2
athlon x2 250 cpu

Hey just to give an update:
Tried 13.10 that MSI recommends on their website. No luck
Also tried 14.4 recommended from amd and no luck.
I wonder if its on our end or the programs end?
If anyone who has a 280x working well know of any tricks to try?
