1600mhz upgrade from 1333hz supported mobo

[asando10]

My build came preinstalled with kingston 1600mhz 4x1 ram but the mobo (gigabyte GA-78LMT-S2) supports up to 1333mhz of ram how is this possible it also shows on cpu-z that its running at 800mhz is it possible that the mobo downgraded the ram speed?

800 is true freq - you are using DDR (DOUBLE data rate) so true (800) x 2 = effective (1600). Depending on how strong your MC (memory controller) is, 1600 shouldn't be a problem
