Product Description
The HP DC390X is a 512MB memory module designed in the SODIMM (Small Outline Dual In-line Memory Module) form factor, commonly used in laptops and other compact computing devices. This module utilizes DDR (Double Data Rate) SDRAM technology, which allows for data transfer on both the rising and falling edges of the clock signal, effectively doubling the data throughput compared to older SDR (Single Data Rate) memory. Operating at a speed of 333MHz, this module corresponds to the PC2700 standard, indicating a theoretical bandwidth of 2700MB/s. The CAS Latency (CL) is rated at 2.5, representing the number of clock cycles required to access a specific data column. The 2Rx8 configuration signifies that the module has two independent memory banks (ranks), each organized as 8 bits wide. This dual-rank configuration can sometimes offer performance benefits in systems that can effectively utilize it. This specific HP part number, DC390X, suggests it is intended for use in HP portable computers or systems that require this exact specification. Memory upgrades are a common way to improve the performance of older laptops, enhancing multitasking capabilities and the speed at which applications can load and run. It is crucial to verify system compatibility, as DDR memory is not interchangeable with DDR2, DDR3, or DDR4 memory types.
