Black BD512M333ME07 Diamond 512MB DDR-333MHz UDIMM 2Rx8 CL2.5 Memory

Product Description

The Black Diamond BD512M333ME07 is a 512 Megabyte (MB) Unbuffered Dual In-line Memory Module (UDIMM) operating at a speed of 333 Megahertz (MHz). This memory module utilizes DDR (Double Data Rate) technology, which allows it to transfer data twice per clock cycle, effectively doubling its bandwidth compared to older SDR (Single Data Rate) memory. The '333MHz' designation refers to its PC2700 rating, indicating a theoretical peak transfer rate of 2700 MB/s. The '2Rx8' configuration signifies that the module is dual-ranked, meaning it has two independent sets of memory chips (ranks) that the memory controller can access. Each rank uses x8 (8-bit) DRAM chips. Dual-rank modules can sometimes offer a slight performance advantage over single-rank modules in certain applications due to interleaving capabilities, but they can also be more demanding on the memory controller. The 'CL2.5' indicates a CAS (Column Access Strobe) Latency of 2.5 clock cycles, which is a measure of the delay between when the memory controller requests data from a specific column and when the data is available. This UDIMM is designed for standard desktop or server systems that support DDR-333MHz memory. It is an unbuffered module, meaning it does not have a register to buffer command and address signals, making it suitable for most consumer-grade motherboards and some entry-level servers. The 'Black Diamond' branding suggests it is part of a performance-oriented line of memory products, though the specifications provided are standard for DDR-333 CL2.5 modules.
