8GB DDR3L 1066 ECC RDIMM for Server Use

This 8GB DDR3L 1066 ECC Registered DIMM is built for server and workstation systems that require error-correcting memory. It operates at 1.35V low voltage and uses a 4Rx8 organisation with CL7 latency. The module replaces Samsung M393B1K73CH0-YF8, M393B1K73CHD-YF8, M393B1K73DH0-YF8 and M393B1K73QB0-YF8 part numbers.

Installing 240-Pin DDR3L Registered Modules

Installation follows the standard 240-pin DIMM procedure: power down, open the chassis, align the notch, and press firmly until the retention clips lock. Registered modules add a clock cycle, so the memory controller must support registered DIMMs; mixing registered and unbuffered DIMMs will prevent boot. Handle modules by the edges to avoid static damage to the major brand chips.

Verify DDR3L 1066 Registered Support Before Order

Confirm your system accepts DDR3L 1066 (PC3L-8500) ECC Registered memory and provides 240-pin DIMM slots. Check the maximum supported capacity per slot and the total number of ranks the memory controller can address. Ensure the platform supports 1.35V low-voltage operation; some older chipsets require 1.5V DDR3 and will not post with DDR3L modules.

Questions about this item

How can I confirm the 8GB DDR3L 1066 ECC RDIMM is running at the correct 1.35V and 1066MHz after installation?

Enter the server BIOS or UEFI and open the memory information screen; it should report 8GB per module, DDR3L 1066 (PC3L-8500), CL7 latency, registered ECC operation and 1.35V voltage.

What is included in the package and do I need any extra parts to install this 240-pin module?

The box contains one 8GB 240-pin DDR3L ECC RDIMM; no additional cables, brackets or cooling parts are required — just an available registered DIMM slot on a compatible server board.

My system lists Samsung M393B1K73CH0-YF8 and M393B1K73QB0-YF8 — which A-Tech version matches those part numbers?

This single 8GB DDR3L 1066 CL7 1.35V 4Rx8 registered module is the direct replacement for all four Samsung part numbers shown.
