Is my RAM running at the correct speed?

It's running at 1564.4MHz; the specs are 1600MHz, so the RAM speed is pretty close to the specs. Your ratio FSB RAM is 2:8; it looks like you may be OCing your system. If so it is not usual to run the RAM a little under or over its specs.

Hi.

Since DDR means double-data-rate, u need multiply by two (2) the speed that u see in CPU-Z.

782.2MHz * 2 = 1564.4MHz, that is the 1600 standard speed.

The timings looks good for ur RAM, just be sure that the voltage isn't above 1.65V or can hurt your processor.
