A-Tech 4GB DDR4 2133 ECC RDIMM

This 4GB DDR4 2133 ECC registered DIMM is built for server and workstation systems that require error-correcting memory. It operates at 1.2V with CL15 latency and uses a 1Rx8 rank configuration. The module fits 288-pin DDR4 slots and is validated as a replacement for specific HP part numbers.

DDR4 2133 registered DIMM limits

Registered DIMMs add a clock cycle of buffering, which stabilises heavy loads but prevents use in most consumer desktop boards that expect unbuffered modules. The DDR4 2133 speed caps bandwidth at PC4-17000, so faster CPUs or chipsets will downclock to this rate. ECC function only activates when the platform firmware enables it.

Installing a single 288-pin RDIMM

Align the notch on the 288-pin module with the slot key, press firmly until both latches click, and verify the system POSTs with the new capacity shown. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong order for the memory controller, or leaving ECC disabled in BIOS so the extra parity bits are ignored.

Questions sur cet article

Should I pick a single 4 GB module or combine multiple sticks?

Each module is 4 GB, so start with one stick and add identical 4 GB DDR4 2133 ECC RDIMM 1Rx8 units to reach your server’s target capacity.

What does the 2133 MHz rating deliver inside a server?

The module runs at DDR4 2133 MHz (PC4-17000) with CL15 latency, giving standard DDR4 bandwidth and registered ECC stability for supported platforms.

How does the 288-pin DDR4 RDIMM interface limit speed and capacity?

The 288-pin registered DIMM slot caps operation at DDR4 2133 MHz and 1.2 V; total capacity depends on how many slots your motherboard provides.
