Where is the difference between type P and type X Chipsets?

Type X such as X48 and X38 have aggressive settings for memory timings. For example, when computer memory using a premium, then the computer can use a premium with low latency memory.So the waiting time can be reduced to the board with the chipset X.This theory of Intel's X48 has a technique that is more aggressive memory timings and supports XMP features with a specially designed with DDR3.

Another thing in different types of X is to have more VGA slots (two pieces).Another difference for the chipset type X for example supports DDR3 speeds higher than that of type P.But the latter is not exactly of the existing theory, since this type of P can be accepted as the type of chipset memory speed X.

Choosing a board with the X48, when the board of this type can be said to be different.Board with the X48 is already prepared to get a processor with 1600Mhz FSB.Like most pricey processors from Intel Core two Extreme QX9770 type.Looking at the ability of X48 chipset, so far no different from the X38 board.For speed is slightly above X48 X38 processors with higher speeds.Of work there is the query, do I require to make use of the QX9770 processor or processors with FSB speed of 1600Mhz which is still pricey.The answer depends on the needs of utilizing, as there is no harm using the X48 board unless the cost offered is higher
