Extended Product Information

FAQs

Is this module compatible with my standard desktop PC?

No, this is a Registered DIMM (RDIMM) meant for server and workstation hardware. Most consumer motherboards do not support registered memory.

What is the benefit of ECC memory?

ECC (Error Correction Code) memory can detect and fix data corruption, which prevents the system from crashing and protects data integrity.

Can I mix this module with non-ECC memory?

It is not recommended. Mixing memory types can cause system instability or result in the system failing to boot.

What does 2Rx4 signify?

This refers to the chip organization (two ranks, 4-bit wide chips), which is important for motherboard compatibility and memory controller channel optimization.

Does this module support 3200 MHz speed automatically?

The module is rated for 3200 MHz, but the actual operating speed depends on the memory controller of your CPU and the motherboard's maximum supported frequency.

Troubleshooting

System does not boot or emits memory error beeps.

Ensure the module is fully seated in the slot and the locking tabs are secure. Verify that your system supports RDIMM memory.

Memory is not recognized by the operating system.

Enter the BIOS/UEFI settings to ensure the memory is detected. If it is not showing, try reseating the module or testing it in a different compatible memory channel.

Pros and Cons

Pros

  • High data reliability with ECC support
  • Significant capacity for memory-intensive tasks
  • Stable performance under heavy system loads
  • Standardized 288-pin compatibility

Cons

  • Requires server-grade hardware (RDIMM support)
  • Not intended for standard consumer desktop motherboards
  • Limited to specific Dell-compatible platforms

Setup, Compatibility & Care

Before installing the module, ensure your system BIOS is updated to the latest version. This module is a Registered (buffered) DIMM; it is strictly intended for servers or workstations that support this memory type. To install, power down the system, discharge static electricity, and align the notch on the memory module with the slot on the motherboard. Press firmly until the side tabs click into place. Keep the module in an anti-static bag when not in use and avoid touching the gold contact pins to prevent oxidation and contact issues.
