Description

Description

Upgrade your laptop or mini PC with the Patriot Signature SO-DIMM DDR4 RAM, increasing the execution speeds of all your processes.

DDR4

DDR4 is the fourth generation of RAM memory technology for computers. It replaces DDR3 and offers increased speeds and greater capacity than its predecessor.

Specifically, DDR4 offers operating speeds from 2133MT/s to 4800MT/s, response time (CAS Latency) from CL 9 to CL 22, while its capacity has increased up to 32GB per memory module.

For speed (MT/s) and capacity (GB), the larger size we choose and is supported by the motherboard, the better, while for response time (CL), we want the smallest size in relation to speed (MT/s).

Patriot Signature provides speed at 2666MT/s, with CL19 and 4GB per memory module.

Compatibility

The DDR4 technology is compatible with specific motherboards and processors. Specifically, DDR4 is compatible with Intel Skylake, Kaby Lake, Coffee Lake series processors, as well as the latest Intel processors, and AMD Ryzen and Threadripper series processors.

However, for compatibility with your motherboard, you need to make sure that your motherboard supports DDR4 technology from the manufacturer. Compatibility depends on the processor platform and the type of motherboard you are using.

Easy Installation

To install it, you only need a screwdriver and your laptop's user manual. By watching a video for your laptop model, you will be able to upgrade your RAM memory without any issues or additional charges.

UDIMM

It is the "classic" type of RAM used by most home computers and gaming PCs for decades.
CUDIMM
No

CUDIMM

Clocked Unbuffered DIMM. This is the new DDR5 standard designed to break the barrier of very high speeds. It features an additional chip on the RAM stick called the Client Clock Driver (CKD). Requires support from CPU/Motherboard (e.g. Intel Arrow Lake and later)

Special Features

Modules

The number of memory sticks. The motherboard should have the corresponding number of slots.

Often, the use of multiple sticks is preferred, allowing them to operate in parallel (e.g. dual channel), which offers better performance. To operate memory sticks in parallel, the motherboard must support it.
CAS Latency
19

CAS Latency

The response time of the RAM memory to the commands received by the system.

The smaller the better for memories with the same frequency, otherwise the frequency is more important for the speed of the memory.
RGB Lighting
No

RGB Lighting

It features built-in RGB lighting with multiple colors.

The RGB lighting can take on various shades by combining the colors red, green, and blue, offering a modern aesthetic result.
