That's a good question. Yes, all AMD or I should say most support the max. DDR400 for super stability. However, due to the High Performance Memory
design, motherboards or system configurations may or may not operate smoothly under standard, stock settings (the BIOS default on the motherboard) such as DDR voltage, memory speeds and memory timing. For this, you will need to check out the manual or online info regarding your RAM and adjust your memory setting in the BIOS accordingly for better system stability.
Here's an example I grabbed from Kingston's website on their high performance RAM:
"Kingston HyperX DDR500 PC4000 operates at 2.65V, 3-4-4-8, CL=3. "
This is only an option to OC. If it fails to work, go back to stock settings and run on DDR400.
