Question on RAM

Okay, so I see these 2 different sticks of RAM.

#1: Kingston HyperX DDR3 1600

#2 G.Skill Ripjaws DDR3 1333 

 My question: What does the stuff in bold mean? Do different RAM sticks have different speeds? If so, how do you indicate which is faster?




DDR3 is the the generation of memory (like PCI-E 2.0/3.0) except it's not backwards compatible. DDR3 is the most prevalent RAM type right now (though I've heard that the DDR4 stuff is done now). The numbers are the clock speed of the RAM in MHz so the Kingston is clocked and 1600 MHz and the G.Skill is clocked at 1333 Mhz. The higher the Mhz is the faster it is. Just be careful as some high speed RAM (mostly 2133 and higher) can have cast latency issues which is a little complicated to explain.

Wow, you answered it completely. Thanks o.o
