My memory is 1333Mhz and it's showing 667Mhz

Hi.

I had a previous PC that i built with Athlon II x64 (2.6Mhz) and memory of 4GB DDR2 800Mhz (2x2GB).
This system was fast enough to work with Windows and other software like Office and Adobe Photoshop, Dreamweaver, etc...

Last week i had a chance to upgrade it all except the HDDs and the PSU.
Now i have the Phenom II x4 955 BE and the motherboard from ASUS M5A88-M with memory from Corsair 8GB DDR3 PC3-10600 1333Mhz (2x4GB).

I installed Windows and everything i needed like before.
But, i don't see any improvement in my speed.

I checked the speed of the memory and it was showing 667Mhz...
In the BIOS i changed manually from AUTO to 1333Mhz and i saved it.
After checking again i see no change.

What can i do or check to get my system to be very fast as it should be?

It's running at 1333mhz. It's just ddr(double data rate) ram 667mhz x2= 1333mhz

Thank you for the answer, this explains the memory speed display.
But how can i see my system running fast with the new specs?
