So I just recently transferred all the parts from my old setup, no case... to my new case which i just purchased. Before transferring I has a RAM speed of 1300mhz, which was fine. However, I just happen to see that the speed of my RAM now is only 667mhz. When transferring parts to the case, I didn't touch the RAM. I simply left it in the motherboard. I'm not sure why it got decreased at all... Any thoughts or possible solutions would be awesome! Thanks!

The DRAM appears to be running at 1333, (DOUBLE data rate (DDR) is true freq (667) times 2 = effective 1333. What you are seeing where it shows some at 1333 and some at 1600 - it's taking the default boot freq from the SPD of the sticks which is simply info on the DRAM, might want to grab CPU-Z (free utility program and look in the MEMORY tab - it will tell you true freq (remember take that times 2) and the timings you are currently running at

It could actually be the same speed, for instance DDR2 is 'double-pumped' so 667 can be reported in one place while 1300mhz is reported elsewhere. Let's clear that up: Where are you seeing this speed reported? BIOS? Speccy? etc.

I'm seeing this all on task manager. RAM is 6GB of DDR3, 4GB of 1600mhz RAM and another 2GB of Kingston HyperX blue 1300mhz RAM.
