DDR2 1066 Question

The 1066 speed is not officially supported by your standard AM2 processors (i.e. Pre-Phenom). AM2+ is a modification to the standard AM2 socket. It is denoted as AM2+, this does not mean AM3.

Your Phenom, Phenom II, and newer Athlon processors (the ones based on the Phenom core) will support the 1066 speed natively (i.e. without manual overclock).

You can use DDR2 1066 memory with any DDR2 motherboard and processor, just note that you might not get 1066 speeds if you have an older AM2 processor.

Yes, an AM3 processor will support the 1066 speed.

Sorry, I misunderstood your initial confusion. An AM3 in a AM2+ board acts like an AM2+ processor. I was confused, thinking that you read AM2+ as AM3, my mistake.

Uh oh, now you've confused me. The board does use DDR2 memory, right? AMD made their AM3 processors so they will work in AM2+ motherboards. Unfortunately, motherboard manufactuers like to use this fact to label their AM2+ motherboards as AM2/AM2+/AM3, but in reality, its just an AM2+ board. The memory is the key. If a board uses DDR2, its AM2+, if it uses DDR3, its an AM3 board. I just want to make sure I'm not leading you astray.


My answer is still the same though, your AM3 processor will run DDR2-1066 speeds, as long as your motherboard supports both.

AM2+ uses DDR2 533/667/800/*1066

AM3 uses both DDR2 and DDR3 depending on mobo.....

AM2 uses 400/533/667/800

Yes, depending on the mobo, If the mobo is AM3 only then you can only use DDR3

If the mobo is AM2/AM2+/AM3 then it is a DDR2 board only......
