    Desktop Processor & Motherboard Matching Difficulties


      Dear All,

      I am trying to assemble a new desktop computer. Before start assembly, it is extremely necessary to identify the motherboard which is compatible with the desired Intel processor. Once I go through the Intel's Classic series motherboards, there were so many compatible processors (with many Bus speeds) listed. For an example, Intel DG41MJ desktop board is compatible with 24 Intel Core 2Duo processors with number of bus speeds such as: 1333 MHz, 1066 MHz & 800 MHz. Honestly I was confused by viewing this .  There should be at least one or two 100% compatible processors out of those 24…..?? Am I rite???


      I red some articles regarding FSB (Front Side Bus). According to one of the articles published in Wikipedia, the FSB is the data path that links the processor & the "Northbridge". The Northbridge has all the connectivity with Graphics & memory (RAM). Therefore they state the Memory Bus & the Front Side Bus should share the same speed. As a result unnecessary bottlenecks could be eliminated & over all system's performance would be increased. By considering above factors, what I could decide is the processor that has the exact frequency of the Memory Bus as the option. For ease of understanding I would take the above example (Intel DG41MJ desktop board). From the list of 24 compatible Core2Duo processors, what I could decide is the processors which have 800 MHz Bus speed (Ex: E4700 Processor).  The reason is, the Intel DG41MJ desktop board supports DDR2 SDRAM with 800MHz Memory Bus.


      I do not know whether I am wrong….. Please explain this to me.  I strongly welcome your  valuable corrections & suggestions……

      Thank you
