DDR3 SDRAM (Double Data Rate Type 3 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 efficient power consumption compared to its predecessors. DDR3 memory operates at a voltage of 1.5V, which helps to reduce energy costs while maintaining performance levels suitable for modern applications.
| Data rate | 800 to 2133 MT/s |
| Voltage | 1.5V (standard), 1.35V (low voltage) |
| Package types | DIMM, SO-DIMM |
| Capacity | 1GB to 16GB per module |
| Width | 64 bits (standard for DIMM) |
When selecting DDR3 SDRAM, buyers should consider the required data rate and capacity based on their specific application needs. It's important to specify the module type (DIMM or SO-DIMM) and whether low voltage options are necessary. Additionally, checking compatibility with the motherboard and existing memory is crucial. Buyers should also inquire about any specific grades or performance specifications required for their systems.
