4GB DDR3 1600MHz ECC Registered RDIMM

This 4GB DDR3 module runs at 1600MHz with CL11 latency and 1.50V operation. It uses a single-rank 1Rx4 layout and registered ECC design for server stability. The 240-pin RDIMM form factor fits compatible Supermicro platforms. It is built for systems that require registered error-correcting memory.

Check motherboard manual for DDR3 RDIMM support

Verify that your board accepts registered ECC DDR3 DIMMs before ordering. Consumer desktop chipsets often reject registered modules or limit ECC functionality. Confirm the maximum supported speed and voltage per slot. Mixing registered and unbuffered DIMMs will prevent boot.

Supermicro certified with major-brand chips

The module carries Supermicro MEM-DR340L-HL01-ER16 certification and uses Hynix HMT351R7BFR4C-PB components. Registered signalling reduces electrical load on the memory controller in multi-DIMM configurations. Standard 1.5V DDR3 voltage matches server platform requirements. 240-pin keying prevents insertion into incompatible slots.

Questions about this item

Does the single 4 GB module ship alone, or are extra brackets or cables included?

The box contains one 4 GB DDR3 RDIMM module and nothing else; no brackets, cables or additional hardware are supplied.

Should I choose the 1Rx4 CL11 version or a different rank and latency for my Supermicro server?

This module is a single-rank 1Rx4 design with CL11 timing at 1600 MHz; select it when your system requires that exact rank configuration and latency.

What does the PC3-12800 rating mean for actual throughput in a registered ECC server?

PC3-12800 indicates a peak transfer rate of 12 800 MB/s at 1600 MHz, delivered through registered ECC circuitry for error-corrected stability.
