Be Ma :
i have a mobo with DDR3 1600, and i have a RAM PC10600,are both compatible with each other ?
and if both compatible, are there any effect to my PC ?
Possibly.
PC3-10600/10666 is DDR3-1333. It is extremely unlikely that a DDR3-1333 value memory stick will run at DDR3-1600 speeds. However, DDR3-1600 modules are almost always rated to run just fine at DDR3-1333 and indeed will often have the appropriate memory profile on the SPD for automatic configuration. However, since you're mixing modules,
even at the same speed, the timings could be different and differences in manufacturing may cause issues. It is likely that they will work just fine together at the lower speed, but it is not guaranteed.
