Hey Hi der guys.. New guy here.... i have a small Doubt... Can i use 533 DDR2 and 800 DDR2 Together? i have 2 -533 DDR2 ram in my mobo now.. and i have 2 more slots available. I'm planning to buy 1 GB more. but my vendor says that 533 speed ones are not available anymore. So i'm going to buy 1GB DDR2 Ram 800 from him(make-transcend). Will any problem pop up or smthin? Coz i heard that The higher speed one will lower its speed to the lower-speed DIMM,so. will it be ok? My Specs Are: C2D 6000Series 1.8Ghz, intel P965LT Mobo 2x512 Mb DDR2 Ram (533), Asus GeForce 6200TC 256Mb 2x250Gb Samsung Hdd DVD Writer.
