Hello,

I am new to pc building and one of the things that I don't understand is memory. How do I know which memory is faster or better? I already read the rules but still don't understand. I just want to know what is the best for gaming and overall.

For example:
(G.SKILL) RipjawsX DDR3 1600 8G(4G×2)(F3-12800CL9D-8GBXL)
CL9-9-9-24 <--- Is this important? Higher number better or lower numbers better?
1.50 Volt <---What about this?

(G.SKILL) RipjawsX DDR3 2133 8G(4G×2)(F3-17000CL11D-8GBXL)
CL11-11-11-30
1.50v~1.60 Volt

(G.SKILL) SNIPER DDR3 2400 8G(4G×2)(F3-2400C11D-8GSR)
CL11-13-13-31
1.65 Volts

What I understand is that from those 3 the Sniper is faster because it says 2400Mhz? The higher the Mhz of a ram the faster it will work?

Thanks in advance,
Ric

Hi,

In a sense you are right but since ddr2 -ddr3 has come to the market, you need to consider the cl (timing)
Ex a 1600 mhz cl 11 would be very similar to 1333 ghz cl 8.

The thing you need to look for is high GHZ with lowest CL .

Also you need to consider your system (cpu and mobo) because an older cpu might not support higher speeds. (1st or 2ndgeneration of core i5 doesn't really benefit from 1600 or higher unless you overclock)

In the list above, the first kit (1600) should have similar performance or better than the two other kits. But probably not much noticeable difference

The voltage is important because your motherboard might not support it.

Hi.there is not huge diiference between 1600 and 2400.
Always go for lower latency and 1.5v
and ofc your motherboard should support 2400 if u want to attach 1.some motherbords dont support more than 1600
