Description
The Hynix HMT42GP8MFR8A-G7AT-AA is a high-capacity 16GB memory module engineered for demanding computing environments. As a DDR3 Unbuffered DIMM (UDIMM), it is suitable for systems that do not require registered memory, often found in workstations and some server configurations. The module operates at a clock speed of 1066MHz, corresponding to a PC3-8500 designation, which indicates its bandwidth capabilities. This memory module features a 2Ranks x 8-bit (2Rx8) configuration. The '2Ranks' indicates that the memory chip is divided into two independent sets of memory banks, allowing for more efficient data access by interleaving operations between the ranks. The '8-bit' refers to the data width of each individual memory chip. With a CAS Latency (CL) of 7, it signifies the number of clock cycles required for the memory controller to access a specific column in a row once the row has been opened and the column address has been sent. Lower CAS latency generally translates to faster response times. Designed for reliability and performance, the HMT42GP8MFR8A-G7AT-AA is a crucial component for systems that handle large datasets, complex simulations, or intensive multitasking. Its substantial capacity and efficient operation at 1066MHz make it an excellent choice for upgrading existing systems or building new ones that require robust memory performance.
