FAQ
What type of systems is this memory module compatible with?
This AddOn A6994477-AM memory module is designed for server systems that support DDR3-1333 registered ECC memory with a 240-pin RDIMM form factor. It's specifically engineered as a compatible replacement for Dell servers and other platforms requiring this memory specification. Always verify your server's memory requirements before installation.
What does Registered ECC mean for server memory?
Registered ECC combines two server-grade memory technologies. The registered (or buffered) design includes a register between the memory controller and DRAM chips to improve signal integrity in systems with multiple memory modules. ECC (Error Correcting Code) detects and corrects single-bit memory errors automatically, preventing data corruption and system crashes in mission-critical applications.
How does the 1.35V voltage compare to standard DDR3 memory?
This module operates at 1.35V, which is lower than the standard 1.5V for most DDR3 memory. The reduced voltage decreases power consumption and heat generation while maintaining full performance at 1333MHz. This makes it suitable for energy-efficient server deployments and systems designed specifically for low-voltage DDR3 memory modules.
What is the difference between RDIMM and other memory form factors?
RDIMM stands for Registered Dual In-line Memory Module, which includes a register chip that buffers address and command signals. This differs from UDIMM (Unbuffered) modules commonly used in desktop systems and LRDIMM (Load Reduced) modules used in high-density server configurations. RDIMMs provide better signal integrity in systems with multiple memory modules, making them ideal for server applications.
Can this memory module be used in desktop computers?
No, this Registered ECC RDIMM is specifically designed for server platforms. Desktop computers typically use unbuffered non-ECC memory with different electrical characteristics. Attempting to use this server memory in a desktop system would likely result in incompatibility issues or failure to boot, as most consumer motherboards don't support registered memory technology.
What warranty coverage does this memory module include?
This AddOn memory module comes with a lifetime limited warranty, providing long-term protection for your investment. The warranty covers defects in materials and workmanship for the life of the product. This extensive coverage reflects the manufacturer's confidence in the reliability and durability of this server-grade memory solution.
