Out of the box, you'll expect, and might be confused, as to why the RAM is running at 2133MHz. This is pretty standard. So you'll definitely need to go into your UEFI BIOS and select "XMP Profile 1" to ensure it's running at its best. It might vary on how/where you need to enable that. But I've decided to attach some images from my BIOS.
Since I don't have other DDR4 to compare this to, I can't offer benchmarks. All in all, it's low profile, and even if it isn't RGB--it still looks great.

So you'll definitely need to go into your UEFI BIOS and select "XMP Profile 1" to ensure it's running at its best. It might vary on how/where you need to enable that.

These were coupled with an Ryzen 5 2600 and a MSI B450 Tomahawk. It worked greatly and without any problems, was easy to input into the motherboard and came packaged neatly and safely. It also looks good in your system with a black or white setup although it doesn’t come with RGB.
This informational review is aimed for new PC builders. Therefore, if you are already knowledgeable in RAM there is no need to continue.
1. (C15) refers to CAS Latency, which is how quickly your RAM responds to a command, you really won't see a difference at all between CL15 and CL16 although you will notice C15 is considerably more expensive as it is better in synthetic bench marks but you wouldn’t notice this in real world performance. Therefore get whichever one you want.
2. Mhz refers to how fast the RAM performs. The speed of a computer processor, or CPU, is determined by the clock cycle. Computer processors can execute one or more instructions per clock cycle, depending on the type of processor. Therefore the higher Mhz the Ram outputs, the faster the RAM can perform tasks. (3000-3200Mhz is considered the sweet spot for mid-higher end workstation + gaming), any beyond this is overkill for your average needs and unecessary money spent.
3. GB refers to Gigabytes: Some computer programs, especially Windows, uses RAM to swap frequently loaded programs back and forth, it makes the computer seem to run faster. Therefore in simple terms, the higher the GB the more tasks your system can perform at once before it starts slowing down your machine.
Recap: What you want in your system for your needs
1. Higher GB
8GB is standard for workstation purposes and light gaming.
16 GB recommended/a must for medium to higher end gaming.
32 GB is for higher end computers, and unecessary unless you are doing a very heavy work load at once which requires it.
(More GB = More tasks your machine can run at once)
2. Mhz
(3000-3200 is the sweet spot, nothing more is required unless necessary for your use).
3. Brand
Brands make their ram different. However Corsair is known for its tech, are very reputable and trustworthy, therefore they are a company you can depend on that make good quality products.
4. (CAS Latency)
Latency won’t be an issue, get which ever one is labelled cheaper as long as it has any of the above I mentioned.
Happy building!
There are other, different frequency RAMS, but offset by worse timing and higher prices so overall tiny performance increases at higher cost. If you really want the next step up, another two percent performance, then you have to increase your spend by 20% or so and buy 3200Mhz CAS 14.
Do remember that there is no guarantee that this will work at the advertised settings in your PC. This is not a limitation of the RAM, rather of your PC. The default setting for the RAM is 2133, and every system will run at that speed but the moment you go above that frequency the rest of your system may well fail. To try full speed you need to enable XMP in the BIOS. If that doesn't work then it's down to you to tweak the settings until you find some that works. No guarantees. Series 7 is guaranteed to work at 2133 and series 8 at 2666, but most will work at 3200. 3000 and 3200 are popular and performance difference between them is pretty much unmeasurable so just buy which is cheaper.
On XMP I discovered my motherboard was going just a bit high on the voltages so I actually set everything up manually and slightly lowered the voltage. In fact it was 100% happy at 1.3V.
"Best RAM" searches on Google almost always return Corsair LPX as one of the best buys out there. RAM has become more and more pricey over the last few years, and so I recommend you go with a trusted brand like Corsair. (Even if it costs a little extra) DDR4 is much faster than existing DDR3, just make sure your current build is compatible with the upgrades! Well worth the money.
