  • 50 V standard voltage ensures broad platform compatibility

Server Memory Upgrade

This A-Tech module provides 8GB of DDR3 ECC UDIMM memory for server and workstation systems. It replaces Samsung M391B1G73BH0-CK0 and M391B1G73QH0-CK0 part numbers. The unbuffered design fits standard 240-pin DIMM slots. Builders needing registered DIMMs or larger capacities should look elsewhere.

Thermals and Power Draw

Standard 1.50V DDR3 voltage keeps power consumption in line with JEDEC specifications for this speed grade. ECC error correction adds minimal overhead during normal operation. Passive cooling on the module relies on chassis airflow; no active fan or heatsink is included.

Deciding Specification

The 2Rx8 dual-rank organisation with CL11 latency at DDR3 1600 (PC3-12800) determines whether your platform can populate all slots at rated speed. Verify the motherboard qualified-vendor list for this exact rank and latency combination before ordering.

Questions sur cet article

How do I install this 240-pin DDR3 ECC UDIMM and what step is often missed?

Align the notch on the module with the key in the slot, press down firmly until both side clips click, then verify in BIOS that ECC is enabled and the speed reads 1600 MHz.

What maintenance or replacement will this 8 GB DDR3 1600 MHz module need later?

No routine maintenance is required; keep the server’s air filters clean so the 1.5 V DIMM stays cool, and replace only if memory diagnostics report correctable errors rising over time.

What limit appears first on this CL11 2Rx8 ECC UDIMM under sustained load?

The CAS latency of 11 cycles at 1600 MHz sets the access-time floor, so sustained bandwidth tops out at the PC3-12800 rating before thermal throttling becomes a factor.
