Difference between SODIMM?

[chanwei21]

Kingston KVR16S11/8 (DDR3-1600 8GB*1) = 2,119 **my country price
G.Skill C9 (DDR3-1600 8GB*1) = 2,999 **my country price
G.Skill C10 (DDR3-1600 8GB*1) = 2,599 **my country price
G.Skill C11 (DDR3-1600 8GB*1) = 2,499 **my country price

Q1: What is the difference between those SODIMM memory? **specially G.skill
Q2: Which is better for my GIGABYTE P25W?

The difference is in the latency, but it won't have much impact. Unless your computer is a high-end build which wants to squeeze every single drop of power, it's definitely not worth worrying about, especially since it seems you'll be paying a lot more just for something which you won't notice at all. If it was just slightly more expensive, it'd be a good idea to get the lowest latency, but this isn't the case.

Get the kingston one, in my opinion.

The differences are in the memory timings. The C-number for the G.Skill sticks tells how many clock cycles it takes to complete a memory command (read/write, etc.). The "S11" on the Kingston stick gives the same information. Usually, you want the lowest number you can get.

oh you guys mean S11 and C11 is the same cycle of time? and the C9 is the fastest right?

 

[Kelthar]

Correct. The lowest the faster, but as I said before, it won't be noticeably faster, so your budget should be what makes you decide.

by the way, is the ddr3-1600 and ddr3-2400 really do big difference in performance?

 

[Kelthar]

No.

There were benchmarks, which unfortunately I don't have the link to right now, that showed the difference between 1600Mhz and 2600 (or 2800) was close to NOTHING. By close to nothing means that the difference in performance was around 0.1%.

It'll only make difference if you have a program that specifically needs super-fast RAM (which I don't think there is).

CL11 is the standard latency. If you want maximum performance, CL9 is quickest. Obviously there is a price difference, so consider which would be best for you.

Extreme frequency such as DDR3-2400, can only be used in systems that can support it. Also, only those that can take advantage of it will notice a difference in performance. CPU overclocking is necessary to take advantage of the greater bandwidth. Take an automotive vehicle for example, if you have a fast sports car that can go 100mph, if you drive it in the city with full of traffic, you will never notice any performance difference than a cheap economy car.
