project.

I have several questions:
1) How can I speed up rendering images in high resolution and high quality 2048x xxxx, only those inrteresujÄ… me.
2) One Unlock 2 additional processor cores, but have not noticed improvement in the speed rendering of images, such as whether additional 8 GB RAM help?
My Computer:
AMD Phenom X4 960T, 4 GB RAM and GeForce GTX 560 Ti, windows 7 new drivers, the latest java.
If anyone has an idea or experience of how to speed up rendering please let me know

I'll be very grateful
