Geil doesnt overclock at much!
Its really good memory in my experience but you will get what you paid for in that cas DDR400!
This ram will do whats on the label not much but as drunken mentionned, youu can use memory divider without having much performance penality on the AMD.
That will allow you to overclock your CPU without overclocking the ram!
