8GB DDR3L ECC UDIMM for Servers

This 8GB DDR3L 1600 module is built for server and workstation systems that require error-correcting unbuffered memory. It serves as a direct replacement for Hynix HMT41GE7AFR8A-PB and HMT41GE7BFR8A-PB modules. The single stick adds 8GB of capacity to compatible platforms.

240-Pin Low-Voltage Unbuffered Design

The module uses a standard 240-pin DIMM form factor and operates at 1.35V, reducing power draw compared to standard DDR3. Its unbuffered design means it connects directly to the memory controller without a register, suitable for platforms that support unbuffered ECC. The 2Rx8 organisation uses major-brand chips.

Check DDR3L 1.35V and UDIMM ECC Support

Before ordering, verify that your system accepts DDR3L memory at 1.35V and supports unbuffered ECC UDIMMs. Confirm the motherboard or server documentation lists compatibility with 2Rx8 modules at 1600MHz. Systems requiring registered or fully buffered DIMMs cannot use this module.

Questions about this item

Does DDR3L 1600 PC3L-12800 limit the maximum memory speed to 1600 MHz?

Yes, the module is rated for 1600 MHz and will not run faster than that on any system.

Will this 240-pin DDR3 UDIMM fit in a standard server DIMM slot?

The stick uses the 240-pin DDR3 UDIMM form factor, which matches regular server DIMM slots.

How is the ECC UDIMM installed and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify in BIOS that ECC is enabled.
