I just bought an asus p6t deluxe for my new build and in the manual it says it supports the following ram frequencies: 1600(O.C.)/1333/1066. what does the O.C. mean? that I can only achieve that frequency if I overclock or that I can achieve higher frequencies if I overclock or something totally different?
The "oc" does indeed stand for overclock. If you set your cpu fsb higher than the default setting, the ram is capable of running up to 1600 at the proper voltage. In my bios, 1600 would read as 800 (also true for cpuid). Sometimes the board will choose a lower speed using built in memory ratios to keep the system from crashing. You'll just have to try various settings and see what is the most stable.
It's not dangerous to overclock if you don't get greedy. The question is how much you're willing to raise the cpu voltage to get your system stable. There's no guarantee that your system will be stable, especially with 4-6 ram slots filled. 1066 is what the Intel chipset is guaranteed to run at with stability. The asus board may choose 1066 to run as the default setting regardless of the ram brand. Then you may have to set the ram voltage and speed manually. I read the newegg reviews for ram and motherboards even if I purchase the items somewhere else. If newegg carries your amazon ram, then you may get some feedback from users.
sorry to revive a old post but i have the same question and i have one other question: if i get ram that runs a 1600 and my mobo supports up to 1333 or 1600(oc) the ram will work but it will be under clocked until i "over clock" it back up to 1600?
