Gigabyte GTX 960 4Gb OC XMR (Monero) Hashrate

[Wicard]

Hi all Coiners,

Please help me with this maybe dumb question,

I have seen everyone talking about the 750 ti that can do 250H/s XMR with 680 Cuda Cores and now I have a GTX 960 4Gb OC with 1024 Cuda Cores and I only get 230 to 255 H/s.

Why would that be. ( Is the support for this card limited on ccminer )

PC:
i7 3.4Ghz
6Gb Ram
480Gb SSD
GTX 960 OC
