i just bought these part and put it together yesterday.
MSI 975X Platinum V.2 Socket T (LGA 775) Intel 975X
CORSAIR XMS2 1GB (2 x 512MB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory
Intel Core 2 Duo E6400 Conroe 2.13GHz

i have only changed the mem to what it is. 5.5.5.15 1.9v and the mem frequency to 1 :1.5 so it runs at 800.
I read about putting my cpu at 333x8 but i got a blue screen. it is back at default at 266x8. I am just using stock cooler so i dont want to over heat it or anything but want to atleast run it at what it should goto.
Any help out there would be great..
Oh i also got this for now ASUS EN7950GT/HTDP/512M 256-bit GDDR3 PCI Express x16
maybe anytihng on the vid also if possible

Change the memory freq to 1:1. It will be in synch according to what you set your FSB to. 400 FSB/800Mhz ram. No reason you shouldn't be able to hit 333, much less 400. If you haven't read wusy's guide, do so. If you don't know what you're doing, follow it step by step. If your board isn't listed there, google is your friend. Lots of guides out there.
