Is my RAM a bottleneck my CPU??

[masoumi]

Hi,
I was wondering if a better ram would increase my CPU performance as well?

I've overclocked my core i5 from 2.8 stock to 3.960 GHz and it's stable
but my ram is corsair xms3 and wouldn't allow even the 800MHz in the bios cause it getts unstable and gives me blue-page. so I settled on 722MHz insteed. it's made of four identical 2GB sticks.

Here's some pictures of my CPU-Z pages

thank u for your input!!
