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..

ok, just so long as it will work. I may upgrade to a 478-pin prescott later on, so i didnt want to have to buy pc-2100 then buy pc-3200 when i update the proc.

It's ok to run RAM faster than your CPU-FSB.

The 865PE chipset is a bit strange with RAM at times. It usually doesn't show DDR400 as an option in the BIOS if the external clock speed is set below 200 MHz (either a low FSB CPU or underclocking). If you OC a 533 MHz FSB CPU to 800 MHz FSB, the DDR400 option will show; at 199 MHz, it won't.<br />
<br />
This may not hold true for all BIOSes that run on 865PE boards, but it's fairly common from my experience. You can use PC3200 RAM regardless of the CPU frequency; you just may have to underclock it until you get a faster CPU. If you're planning on getting a Pressy down the road and really overclocking it, you may want to consider good overclocking PC3200 or average PC4000.

Nicely put Taeric <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />

That board is crying out for a 800mhz CPU (prescott or Northwood) but I too dont see it being a problem. <br />
<br />
Could you borrow some DDR400 and test it before shelling out any money?

I dont know anyone that isnt using their ram at the moment <img src="/images/smilies/tongue.gif" border="0" alt="" title="Stick Out Tongue" class="inlineimg" /> , but i think that im just going to get a gig of 3200 and give it a try. If it doesnt work ill just wait a bit and get myself a nice 3.4 prescott as they are getting quite cheap at this point. The motherboard itself is quite condusive to overclocking, i have heard of people getting 3.0 Ghz out of northwoods no problem. I just cant figure out on that particular motherboard what i have to change. My Presler was easy to overclock, but i just cant figure the northy out. Maybe its the ddr-266 i dont know.
