DDR2 is more energy effiecient. But has higher latencies but makes up for it with a higher clock. Running the pc3200 ram will be fine and cheaper.
Im currently in the process of purchasing some ram for my 3.2ghz p4 system. It has 800mhz fsb, 4 available ram slots- 2 of which are standard ddr and the other 2 slots are ddr2 compliant.(mobo is gigabyte 8I915p duo pro)
I have been looking at 1 gb pairs (2 x 512mb)
pc3200 ddr400 and pc4200 ddr2-533
These are the fastest speeds i think my motherboard can handle, the problem is which speed is most suitable. I dont plan to overclock the system, so will running pc3200 in dual channel mean i get the full fsb?
Also is the ddr2-533 ram not neccessary as it exceeds the 800fsb?
I am a little confused at the matter of fsb, multipliers etc so any help here would be great, thanks.
