16GB DDR3 1066 ECC RDIMM

This is a single 16GB DDR3 1066 (PC3-8500) ECC registered DIMM built with major-brand chips. It runs at 1.50V with CL7 latency and a 4Rx4 organisation on a 240-pin form factor. The module is a direct replacement for Hynix HMT42GR7AMR4C-G7, HMT42GR7BMR4C-G7 and HMT42GR7CMR4C-G7 server memory.

Servers and workstations needing registered ECC DDR3

IT teams maintaining systems that require DDR3 1066 registered ECC modules with a 4Rx4 rank layout will find this part a compatible match. Builders whose platforms need unbuffered UDIMMs, a different rank structure, or a higher or lower DDR3 speed should look elsewhere.

4Rx4 rank organisation

The 4Rx4 rank configuration is the critical spec that decides whether this module works in a given server board; the memory controller must support this exact organisation for the DIMM to be recognised and operate correctly.

Questions about this item

What motherboard slot and voltage does this 240-pin DDR3 RDIMM require to operate?

The module fits a standard 240-pin DDR3 DIMM slot and runs at the JEDEC 1.5 V specification.

Can I mix this 4Rx4 registered ECC module with existing 2Rx4 or 1Rx4 sticks in the same server?

Mixing ranks is possible if the motherboard supports 4Rx4 modules and the total rank count per channel stays within the platform limit.

How do I confirm the module is running at 1066 MHz with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode to verify 1066 MT/s speed, CL7 latency and ECC enabled status.
