FSB 800MHZ or 1066MHZ

Since it looks like the current computer is down and I do not feel like spending more time and money trying to figure out what is going on I have decided to look at buying the basic components and building a somewhat new computer.

 

I am currently looing at the ASRock 4CoreDual-VSTA motherboard along with a Intel Core 2 Duo processor. Not wanting to spend a huge amount of money but want something that will hold me over for sometime ( at least a year plus, two would be great) with my current Powercolor X1950 PRO AGP video card. With the curent prices on the processors I am willing to go up to an E6420 but will consider lower performance processors also.

 

My question revolves around the compatibility of the memory determined with the Corsair Compatability table and the different processors. The two lower end processors, E4300 and E4400, have 800 MHZ FSB and the higher ones have 1066MHZ FSB. The table calls for DDR400 which I thought was good for 800MHZ? If I went with a processor that is 1066MHZ I would need..? Am I missing something? Is there a big difference in performance between DDR and DDR2? Also, according to the MB specs it will accept both DDR or DDR2 memory.

 

I am looking to install 2GB of Corsair Ram so which would be the best choice depending on the processor? ALso I do not OC but I would like it to perform well while gaming.

 

Thanks

Robert

With that MB if you are planning to use a 533 or 800 FSB CPU I would suggest VS2GBKit533D2, Or if you will be using an 1066 FSB CPU then use VS2GBKit667D2.

 

DDR2 Memory runs at:

DDR2-533 = 266 Clock Frequency 2 X 266 = DDR2 533

DDR2-667 = 333 Clock Frequency 2 X 333 = DDR2 667

DDR2-800 = 400 Clock Frequency 2 X 400 = DDR2 800

DDR2-1066 = 533Clock Frequency 2 X 533 = DDR2 1066

 

Intel CPU:

533 MHz = 133 MHz Clock Freq. 133 X 4

800 MHz = 200 MHz Clock Freq. 200 X 4

1066 MHz = 266 MHz Clock Freq. 266 x 4
