we had already in detail described, why processors Socket AM3, which relate to the so-called generation K8L,
possible to be used in the existing motherbards with AM2
Socket , point in a question of the mutual compatability of these
platforms was placed early. The combined memory controller will support borth Ddr-2 and Ddr-3 simultaneously, final selection
will be determined by the motherbards possibilities.
Let us recall that although both types of memory use 240-
pin , the signals system used is distinguished, yes even the slots are located in such
way that installing Ddr-3 module into the slot for Ddr-2 will be
impossible.
After installing a Socket AM3 processor into
Socket AM2 motherbard, it will not be only limited by the Ddr-2 support ,
but also to the use of HyperTransport 3.0 V bus usual
HyperTransport 1.0. . Does this mean that
processors Socket AM2 are possible to be installed in am3 motherbaords ???
Associates from site HKE PC introduced clarity into this question. Thus,
processors Socket AM3 budut have 939 legs, whereas
processors Socket AM2 have 940 legs. Already from this
circumstance is not allowed to install processor Socket AM2 (940 pins) into Socket AM3 (939 pins) motherboard-
Furthermore, motherboards with Socket AM3
will be for sure equipped with slots DIMM Ddr-3, and processors Socket AM2 will be able to work only with the memory
type of Ddr-2. thus, preserving old processor with the purchase of
new motherboard Socket AM3 will not be succeed. Perhaps
that someone of the producers is proposed hybrid motherboards with
support of both types of processors,
