I have an MSI 865PE Neo2F in an old system that im resurrecting from the dust and I have a question about ram. In the motherboard manual it says that i cant run pc3200 unless i have a 800 Mhz FSB chip. In the bios i can choose the memory speed that i have no matter what chip is installed. I would like to get pc3200 so that i can take advantage of the 1 to 1 multiplier for the ram. I would think that the performance boost would be nice if i could. Also i do need to upgrade from the 512 mb that i have on there now so im looking to kill two birds with one stone i guess. If i can use the pc-3200 i can upgrade to a prescott later on. I dont want to have to buy the ram twice if i dont have to..
