Server memory upgrade

A-Tech 16GB DDR3L 1066MHz ECC RDIMM module uses major-brand chips on a 240-pin registered DIMM. It runs at PC3L-8500 speed with CL7 latency and 1.35V low voltage. Designed as a direct replacement for Hynix HMT42GR7AMR4A-G7 and related part numbers in server or workstation systems.

Sustained workload behaviour

Registered buffering and ECC protect data integrity during continuous multi-threaded tasks. The 4Rx4 organisation distributes load across four ranks per module. Low-voltage DDR3L operation reduces thermal output compared with standard 1.5V DDR3 during extended duty cycles.

Installation notes

Insert the 240-pin DIMM into a compatible DDR3L RDIMM slot; keying prevents incorrect orientation. Systems requiring unbuffered UDIMM or non-ECC memory cannot use this module. Verify motherboard qualified-vendor lists for 16GB 4Rx4 support before purchasing.

Questions about this item

How much heat does the 1.35 V DDR3L module add when the server runs continuously?

The DDR3L 1066 MHz registered ECC DIMM operates at 1.35 V, which is the standard low voltage for this memory type and keeps thermal output lower than higher-voltage DDR3 modules.

What motherboard slot is required to install this 240-pin registered DIMM?

A DDR3 240-pin DIMM socket that supports registered ECC memory is required; the module will not fit or function in standard unbuffered desktop slots.

Will the 4Rx4 organization work in a system that currently uses 2Rx4 DDR3 registered DIMMs?

Yes, provided the platform supports 4Rx4 registered modules and the total rank count per channel stays within the motherboard's documented limit.
