4GB DDR3 ECC Registered module

This 4GB DDR3 1066MHz ECC Registered DIMM is built for servers and workstations that require error-correcting memory. The quad-rank 4Rx8 organisation and 1.50V operation match the PC3-8500 standard for registered platforms.

240-pin RDIMM installation notes

The 240-pin RDIMM form factor seats in standard DDR3 registered slots, but the quad-rank density means some boards limit the number of modules per channel. Verify the system's qualified vendor list before fitting to avoid POST failures caused by rank-count limits.

Sustained load behaviour

ECC circuitry corrects single-bit errors on the fly during continuous operation, preventing silent data corruption in long-running workloads. Registered buffering reduces electrical load on the memory controller, helping stability when all slots are populated at the rated 1066MHz speed.

Questions about this item

How can I verify the module is running at 1066MHz after installation?

Enter the system BIOS or use a hardware monitoring utility to confirm the memory speed reads DDR3 1066 (PC3-8500) and that ECC Registered operation is active.

What ships with the module and is anything else required?

The box contains one 4GB Hynix HMT151R7BFR8C-G7 RDIMM; no cables, brackets or additional components are included or needed for installation.

Should I choose the 4GB quad-rank 1.5V version or a different capacity?

Select this 4GB 4Rx8 1.50V module when your server requires a single quad-rank DDR3 1066 registered DIMM; match the exact rank and voltage specified by your system documentation.
