"The AMD Phenom II X3 processors are effectively the
equivalent X4 model but with one of the four cores being disabled,
due to chip harvesting. However, as we will share later on in this
review, in some circumstances it is actually possible to re-enable
the fourth core. Beyond having 6MB of L3 cache, there is 512kB of
L2 cache per core and 128kB of L1 cache per core. The memory
controller that is integrated into the Deneb (the quad-core Phenom
II codename) and Heka (the triple-core Phenom II codename) each
support DDR2-1066MHz and DDR3-1333MHz. The DDR2 support is
available when installing the Phenom II within an AM2+ motherboard
while the products using the new AM3 socket are going with DDR3.
The TDP for the AMD Phenom II X3 processors is currently at 95
