The most common laptop memory speeds today are DDR4/2133 and DDR4/2400. You might be tempted to go with an even higher speed, say DDR4/2666, which can yield some performance benefits.

I will shortly be upgrading my CPU and motherboard from an i5-6500 to an i5-9600K, and a B150 board to a Z390 board (Gigabyte Z390 Gaming X). I currently have 4 x 8 GB DDR4-2133 DIMMS in there.

The Crucial DDR4 memory sticks that we will be testing today are a set of 16 sticks with the part number of CT16G4RFD4213. These sticks are 16GB DDR4-2133 1.2v DR x4 RDIMM modules, they are dual ...

In this example, this laptop supports a maximum of 16 GB of RAM across a maximum of 2 RAM slots. How Much Extra RAM Do You Need? There are numerous ways to determine how much extra RAM you need.

There's no single inflection point at which cost skyrockets. $105 for 16GB of DDR4-3200 isn't a bad deal if you can spare the cash -- and if you can't, 16GB of DDR4-2133 isn't going to leave you ...

For example, you might see it listed as DDR4-2133 PC4-17000. Timings are another aspect of memory that can impact RAM performance, although they are no longer as important.

But this explains why in our lead example, DDR4-3600 CAS 20 (11ns) can underperform DDR4-3200 CAS 14 (8.75ns) in certain operations: It takes 2.25ns longer for DDR4-3600 CAS 20 to respond.

Apacer's newly launched DDR4 2133 U-DIMM can be 100% compatible with the x99 chipset platform adopted by Intel Haswell-E, creating a reliable and stable operation environment.

This DDR4 RAM has a 3200 MT/s transfer speed, which is great for a gaming laptop. Its Column address strobe (CAS) latency of CL22 is not that low but should do, as you already have a fast transfer ...

DDR4 is not just more power efficient — it’s a lot faster, too.DDR3 specifications range between 800 to 2,133 MTps (millions of transfers per second). In comparison, DDR4 RAM ranges between ...

The standard for DDR4 chips technically maxed out at 3,200 MHz, which is the new starting point for DDR5. We’ve only seen a few examples of the top end, but DDR5 supports speeds all the way up ...
