Same goes for Intel. You'll see I asked earlier if the memory controller was part of the MB or CPU as I could not remember how far back they switched to an IMC...

Memory controller - Wikipedia

Prior to K8 (circa 2003), AMD microprocessors had a memory controller implemented on their motherboard's northbridge. In K8 and later, AMD employed an integrated memory controller. Likewise, until Nehalem (circa 2008), Intel microprocessors used memory controllers implemented on the motherboard's northbridge. Nehalem and later switched to an integrated memory controller.

I should have remembered this as I had an athlon64
