Really need help....RAM frequency, timing, voltage

I just bought a new system. Here are the specs:

Phenom II 955
MSI GD 70
OCZ 1333 MHz 7-7-7-20 @ 1.8V
Caviar Black 1TB

I have a problem with RAM... How can I get the RAM to work at 1333MHz, with timing of 7-7-7-20, at the voltage of 1.8V?

Then how can I check if the RAM is running at the rated frequency, voltage and timing?

Thanks a lot.

to check speed and timing of memory, like above, cpu-z go to the memory tab

as to change it (if not correct), you have to go into the bios and manually set the timings voltage and speed

each motherboard is different, just read your motherboard manual as to how to do all of this
