Since your memory maximum speed is only 1066 Mhz, the maximum FSB speed for the CPU is 1333 Mhz.
The system will run at the HIGHEST COMMON SPEED, which is 1066 Mhz in your case. If you are using memory with speed 1333/1600 Mhz, then the system will run at 1333Mhz.
Sometimes you need to set it manually in the bios, but in your case, it should run at 1066Mhz.
I guess the memory he is using is a DDR3 1333Mhz frequency: http://www.patriotmemory.com/products/groupdetailp.jsp?prodgroupid=106&prodline=5&group=PC3-10666%20-%201333MHz%20Memory%20Modules&catid=18 (if I am not wrong). Hence if he is not getting the 1333Mhz frequency, then Aranski, I think you will have to try to set it manually and see if it works.This motherboard may sometimes behaves like this, even with the latest BIOS. Hope Intel will fix this with a new bios revision.
Well it just would not work right, the memory is supposed to be DDR31 10666, running at 1333mhz.
So I took everything back to COMPUSA showed them my CPUZ info, and they swapped everything for a new I7,gigabyte GA-ex58-ud3r mb and Partiot DDR3 tripple 1600. , Just now getting ready to update BIOS and see how it runs. I will post my Performace 7 scores here
Now that you have a Core i7, you will still have the memory running at 1066Mhz as the memory controller is on the CPU and this is limited to 1066Mhz.
You may get the memory to run faster by manually changing the settings or using XMP but there is an internal limit on the memory controller in the CPU of 1066Mhz!
