FAQ

What type of memory module is this?

This is a 4GB DDR3-1333MHz Registered ECC RDIMM (Registered Dual In-Line Memory Module). It features error checking and correction (ECC) for data reliability and uses registered (buffered) signal processing for improved stability in server environments. The 240-pin DIMM form factor is standard for server memory installations.

What does Registered ECC mean for server memory?

Registered ECC combines two important server memory features. ECC (Error Checking and Correction) detects and corrects single-bit memory errors to prevent data corruption. Registered (or buffered) design includes a register between the memory controller and DRAM chips to improve signal integrity, especially when multiple modules are installed. This combination enhances reliability for critical server applications.

What is the operating voltage of this memory module?

This DDR3 module operates at 1.35V, which is a low-voltage version compared to standard 1.5V DDR3 memory. The reduced voltage decreases power consumption and heat generation, making it suitable for energy-efficient server configurations while maintaining full compatibility with systems designed for low-voltage DDR3 memory.

What does CL9 latency indicate?

CL9 refers to CAS Latency 9, which measures the number of clock cycles between a memory controller requesting data and receiving it from the memory module. A CL9 rating indicates efficient memory access timing for DDR3-1333MHz memory, balancing responsiveness with the module's 1333 MHz speed for server workloads that benefit from predictable memory performance.

Is this memory compatible with my server?

This module is designed for servers that support registered ECC DDR3-1333 memory with 240-pin DIMM slots. It's specifically compatible with Cisco UCS platforms and other server systems requiring this memory type. Always verify compatibility with your server manufacturer's documentation, as memory requirements vary by specific motherboard and chipset configurations.

What warranty comes with this memory module?

This AddOn memory module includes a lifetime warranty, providing long-term protection for your investment. The warranty covers defects in materials and workmanship for the product's usable life, offering peace of mind for server deployments where reliability and long-term operation are essential considerations.
