1600mhz RAM vs 1866mhz RAM

[welner]

How much better performance can you get out of a

822501 Crucial 16GB Kit (2 x 8GB) DDR3L-1866 UDIMM
CT7372414 DDR3 PC3-14900 • CL-13 • Unbuffered • NON-ECC • DDR3-1866 • 1.35V • 1024Meg x 64

Compared to a

Crucial 16GB Kit (2 x 8GB) DDR3L-1600 UDIMM
CT7347326 DDR3 PC3-12800 • CL-11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 • upgrade for Dell OptiPlex 9010 (Desktop) system.

None whatsoever. Their CAS latency difference makes them pretty much equivalent.
That being said, if they were the same CL, the difference would be frome none to some, depending on what you do wiht your pc.

Don't worry. Go for the cheaper kit. You will not at all notice any performance loss, unless you run a third party artificial benchmark s/w.
On the other hand, in some circumstances a little bit slower memory will be steadier, more robust - in some cases.

As a general recommendation:
The first can only you decide depending of how much and which memory demanding programs you are using.

The second:
When it comes to memory's there are a few things to keep in mind:

1. Always install memory sticks from one memory kit. They are matched together.

2. Always make sure that the chosen memory's is indeed supported by the motherboard and its processor.
Different types of memory's, different frequencies, timings etc. the memory stick with the lowest speed will always set the speed for the rest of them.

3. Very important that the voltage of the memory are supported by the processor; meaning that a memory stick with to much voltage let say 1.7V when the processor spec. clearly says 1.5V - will damage and shorten the processors life span.

4. Make sure that the height of the memory modules can fit under the CPU-cooler (if it is not original).

5. Use a memory configurator such as
Corsair http://www.corsair.com/en-us/memory-finder
Kingston http://www.kingston.com/us/memory/search/options
G-Skill http://www.gskill.com/en/configurator
Etc.

But even then, som memory manufacturers recommend memory's with a little bit to high voltage, so make sure that the CPU manufacturer specs for that particular model of CPU is followed regarding the memory voltage.
Otherwise it will shortened the CPUs lifespan. Over Clocking is always a risk.

For ex. a processor of 2:a generation Intel Core i3, i5, or i7 of Sandy Bridge alt 3: generation "Ivy Bridge" etc. these should have 1,5V +/- 5%- memory's.

For DDR3 memory: 1.5 volts, plus or minus 5%
For DDR3L memory: 1.35 volts, plus or minus 5%
For DDR4 memory: 1.2 volts, plus or minus 5%

When upgrading to a higher GB set of RAM is using a LV-1.35V-type-RAM a better upgrade than upgrading to a RAM kit that uses the original 1.5V type ...
