Frequently Asked Questions

Is this HP 862974-B21 memory module compatible with my non-HP computer?

While it's an HP module, DDR4 DIMM memory is standardized; however, it's crucial to check your specific motherboard's documentation for compatibility with unbuffered 2400 MHz DDR4 RAM.

What does "unbuffered" mean for this memory module?

"Unbuffered" means the memory module sends commands directly from the memory controller to the memory chips, which is common in consumer-grade desktops and typically performs faster than registered memory in those systems.

Can I combine this 8GB module with other memory modules I already have?

You can often combine it, but for optimal performance, it is generally recommended to match memory modules in terms of capacity, speed, and timing, especially for dual-channel configurations.

What speed is this DDR4 SDRAM module?

This HP 862974-B21 memory module operates at a speed of 2400 MHz.

How much RAM does this single module provide?

This HP 862974-B21 memory module provides 8GB of DDR4 SDRAM.

What Buyers Say

4.5 ★★★★★2 Amazon ratings

👍 Pros

This HP 862974-B21 module provides 8GB of DDR4 SDRAM, offering a significant boost to system memory.
Operates at a fast 2400 MHz speed, contributing to quicker data access and improved system responsiveness.
Features an unbuffered design, which is generally suitable for standard desktop and non-server PC systems.
Utilizes a 288-pin DIMM form factor, ensuring compatibility with a wide range of modern motherboards that support DDR4.
As an HP memory module, it is designed for compatibility and reliable performance within HP systems, although specific model compatibility is not detailed.

👎 Cons

Specific compatibility with particular HP computer models is not listed, requiring users to verify their system's exact memory requirements.
Being unbuffered, this module is typically not suitable for server environments that often require registered (ECC Registered) memory.
The capacity is a single 8GB module, which might require purchasing multiple modules for dual-channel setups or higher total memory needs.
The operating voltage for this DDR4 module is not specified, which could be a consideration for precise system builders.
While 2400 MHz is a good speed, higher speeds are available in the DDR4 market for users seeking maximum performance.
