What Slots Does DDR4 Use?

DDR4, also known as Double Data Rate 4, is a type of computer memory that has become increasingly popular over the past few years. One of the most important factors to consider when purchasing DDR4 is knowing what kind of slots it uses. In this article, we will explore the different types of DDR4 slots and what you need to know about them.

Firstly, it’s important to understand that DDR4 memory sticks are not compatible with DDR3 or any other previous memory types. This means that you cannot use a DDR3 memory stick in a DDR4 slot and vice versa. So, if you’re upgrading your computer’s RAM or building a new system, make sure you choose the right type of RAM.

DDR4 uses a 288-pin connector, which is slightly different from its predecessor DDR3 that used 240 pins. The extra pins on DDR4 help improve its performance by allowing more data to be transferred between the memory stick and the motherboard at once.

There are two main types of DDR4 slots – DIMM and SO-DIMM. DIMM stands for Dual Inline Memory Module and is the most common type of slot used in desktop computers. SO-DIMM stands for Small Outline Dual Inline Memory Module and is used in laptops and other smaller devices.

DIMM slots are larger than SO-DIMM slots and can accommodate larger memory modules. They also come in two variants – unbuffered (UDIMM) and registered (RDIMM).

UDIMMs are less expensive but offer less capacity than RDIMMs. RDIMMs are more expensive but can support more memory per module.

SO-DIMMs, on the other hand, are smaller in size but have similar functionality to DIMMs. They are commonly used in laptops because they take up less space than DIMMs. However, they offer less capacity than DIMMs because they can only accommodate smaller modules.

In addition to the standard DIMM and SO-DIMM slots, there are also specialized DDR4 slots such as ECC and ECC registered slots. These are designed for use in servers and workstations where error correction is crucial. They use special memory modules that can detect and correct errors in data transmission.

In conclusion, DDR4 memory uses a 288-pin connector and comes in two main types of slots – DIMM and SO-DIMM. DIMMs are larger and come in two variants – unbuffered (UDIMM) and registered (RDIMM).

SO-DIMMs, on the other hand, are smaller and commonly used in laptops. There are also specialized DDR4 slots such as ECC and ECC registered slots that are designed for use in servers and workstations. Knowing what kind of slot your computer uses is crucial when purchasing DDR4 memory to ensure compatibility and optimal performance.
