Hi, I have the option to run either of the mentioned speeds above, but I don't know if I would really see a difference in speed. I am stress testing currently, so I can't really go into the BIOS and change it, but I mainly game and surf the web. Does anyone know which one would better benefit me with these tasks, or should I just keep it @ 1600 9-9-9-24 like it is now?

CAS Latency is the number of wait cycles, the faster speed of the RAM, the faster these cycles occur. A CAS latency of 7 on 1333 is roughly equivalent to a CAS of 9 on 1600. CAS latency is relative to speed of the RAM, so higher speed RAM will naturally have a higher CAS latency. Go with 1600 9-9-9 as the actual latency will be roughly the same but you will benefit from increased speed.

You see a pretty big jump from 1333 to 1600 so I would go with the 1600. I'm guessing this is for the system in your sig? If so Sandy Bridge does best with DDR3 1600 cas 9. Just make sure you keep it at 1.5v so you do not void the CPU warranty.
 

Believe or not anort3, u void the the CPU warranty with anything above DDR3 1333MHz.

Intel processors are designed to operate the memory at 1066MHZ or 1333MHZ ONLY. The minute you run that memory at anything higher, you void the warranty.

I posted in that thread. There was some question if it was frequency and voltage or just voltage. One poster stated he was only asked about voltage and not frequency. Either way that protection plan is worth looking at for $20-$25.
