If my CPU and motherboards FSB is lower than my rams FSB. Is it pointless to have ram with such a high FSB?

Do I purchase the ddrm3 1333Mhz or ddrm3 (1800MHz) for max performance.


System specs are as follows:





CPU


:Intel Core 2 Duo E8500 CPU, 3.16 GHz, FSB 1333MHz, 6MB L2 Cache, 45nm, Socket LGA775 E8500





Motherboard


GA-X38T-DQ6 Intel® X38 + ICH9R Chipset


1. Supports Intel® Core 2™ multi-core and upcoming 45nm processors


2. Support for 1600 MHz FSB.


3. Dual DDR3 1800 (O.C.) memory with Intel® XMP , featuring faster speeds and performance tuning.





RAM


Corsair TWIN3X2048-1800C7DF 2GB (2x XMS3 1GB) PC-14400 (1800MHz) DDR3 RAM, 2x240-pin DIMMs, Non ECC Unbuffered, 7-7-7-20





or do I buy





Corsair TWIN3X2048-1333C9DHX 2GB (2x XMS3 1GB) PC-10600 (1333MHz) DDR3 RAM, 2x240-pin DIMMs, Non ECC Unbuffered, 9-9-9-27





assuming that the 1800Mhz is to fast for the cpu and motherboard.

MAN the fsb is the front side bus. Which is to do with your processor not your ram. your fsb is 4 times your cpu clock speed and controlls how fast data is transfered to and from your processor NOT your ram. SO 1600 fsb means it fully supports a processor running 3.2 ghz 400 clock speed times a multiplier of 8.





now as for your ram without checking benchmarks idd say get


Corsair TWIN3X2048-1800C7DF 2GB (2x XMS3 1GB) PC-14400 (1800MHz) DDR3 RAM, 2x240-pin DIMMs, Non ECC Unbuffered, 7-7-7-20


as it has not only higher frquency (1800C7DF{1800mhz}) but also has tighter timings (7-7-7-20 )
Reply:It will only go as fast as your mobo can support.
