So i bought a GTX 980 SC a few months ago. (Just rebuilding my rig as i had to sell my last one due to job loss)
 
I've been trying to overclock this thing.
 
So far i have GPU clock offset at 120Mhz.
Memclock off set is at 180Mhz 
with also 31Mv.
 
Now i can't seem to hit past 10k bench score, and im at the point where firestrike won't complete, it says i cancelled it, when i didnt.
 
Anyone got any pointers or decent overclock settings i could use?
 
:)

Hey , thanks! I dropped the overclock by 10Mhz and it ran completely through it. thank you.

Hope this helps.... some of the stuff i don't know.
 
*EDIT*
Ok, so i dropped it down to 110Mhz, card runs at 1515 Mhz when doing firestrike i also put the mV back to 0. Just hit over 10k in score 
 
How can i improve this? Should i up the mem clock offset?
