Hello I just got my brand new gigabyte ga-x48-dq6 (support for ddr2) mb with penryn intel core 2 quad qx9450. My question is - what is the best RAM choice for that setup? Which is better: 800 MHz or 1066MHz (the fsb aspect ratio?) What do you guys think about 2 kinds below: 2 x OCZ 4GB (2x2GB) DDR2 1066MHz Reaper EPP CL5 Heatpipe (OCZ2RPR10664GK) or MUSHKIN DDR2 8GB PC800 DUAL CL4 XP additional info: I want to install and use Vista Ultimate x64 with 8gb ram. thank you for any help and sorry for my english
