Product type
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) is a type of memory integrated circuit used in computers and other electronic devices. It is designed to provide high-speed data transfer rates and improved performance compared to its predecessor, DDR3. DDR4 memory is typically made from silicon and operates on a 1.2V power supply, allowing for greater energy efficiency.
| Data Rate | Up to 3200 MT/s |
| Voltage | 1.2V |
| Capacity | From 4GB to 64GB per module |
| Form Factor | DIMM and SO-DIMM |
| Pin Count | 288 pins for DIMM, 260 pins for SO-DIMM |
| Latency | Typically CL15 to CL19 |
When selecting DDR4 SDRAM, consider the required data rate and capacity based on your system's specifications. It's important to check compatibility with your motherboard, including supported voltage and form factor. Additionally, inquire about the latency and whether you need modules with specific grades or certifications for reliability. Specify the quantity needed to ensure bulk pricing if applicable.

DDR4 offers higher data rates, lower voltage, and improved efficiency compared to DDR3.
No, DDR4 is not backward compatible with DDR3 motherboards.
CL stands for CAS latency, which indicates the delay time between a memory request and the data being available.
Typically, 16GB is recommended for most gaming setups, but 32GB may be beneficial for high-end gaming.
Yes, individual DDR4 modules can range from 4GB to 64GB, but the total capacity depends on the motherboard.
The most common form factors are DIMM for desktops and SO-DIMM for laptops.
