Okay so i gain about 4mhash/s when i drop the mem to 300, Not worth it.
So how 'bout that voltage control? according to MSIa my core can go as high as 1565mhz, orcourse i dont expect it to get there, but i can reach 1015 stabily without touching the untouchable voltage options, currently im stabily running at 1.01ghz
and with 99% GPU usage and fan at 75% i do not exceed 80°c wich sounds great to me. (ran for 12hrs)
