I both one stick of DDR3 2GB RAM 1333MHz (KVR1333D3n9/2G) i put it on my motherboard (EP35C-DS3R). But the RAM wont work at 1333 mhz its working only at 800mhz... just like my old DDR2. Please tell me how to make it faster...
check to see if the new RAM you really bought is 1333, other than that, I can't help you because the motherboard specs handle both DDR2 and DDR3 at most bus speeds.
