Micron MT9HTF6472Y-667D4D3 512MB DDR2-667MHz RDIMM 1Rx8 CL5 Memory

Product Description

The Micron MT9HTF6472Y-667D4D3 is a 512 Megabyte (MB) DDR2 SDRAM module configured as a Registered DIMM (RDIMM). Registered DIMMs are designed to reduce the electrical load on the memory controller by buffering address and command signals, which is crucial for system stability in servers and high-density memory configurations. This module operates at a higher frequency of 667MHz, corresponding to the PC2-5300 standard, offering improved performance over slower DDR2 modules. This memory module is organized as 1Rx8, meaning it is single-ranked with eight memory chips (each 8-bit wide) contributing to the data bus. The CAS Latency (CL) for this module is 5, indicating that it takes five clock cycles for the data to be available after a column address command is issued. While CL5 is higher than CL3 found in some DDR2 modules, the increased clock speed of 667MHz generally results in higher overall bandwidth. The module operates at the standard 1.8V required for DDR2 memory. Consistent with its use in server environments, the MT9HTF6472Y-667D4D3 includes Error-Correcting Code (ECC) capabilities. ECC memory can detect and correct single-bit errors and detect multi-bit errors, significantly enhancing data integrity and system reliability. This makes it an ideal choice for applications where data accuracy is critical. The 240-pin connector ensures compatibility with DDR2 RDIMM slots found on server and workstation motherboards.
