Problem with Memory Frequency

[makdak]

Hello, i have the following problem with my system. I have a set of 3x1GB OCZ DDR3 PC3-10666 (which supports maximum DRAM Frequency @ 1366 Mhz) installed on my computer, and i've left the DRAM Freq. in the BIOS at Default which is 1066. The problem is that when i check DRAM Freq. with CPU-Z it says 540 MHz, fluctuating +1/-1 MHz and that doesn't go up although i stressed it with Prime95. Any ideas?

Nevermind, i figured it out
It's seems to be like 540 * 2 = 1080Mhz (looks like i ran more than 1066 for some reason )
