SK hynix HMA81GR7CJR8N-WM 8GB DDR4 2933 ECC Registered server RAM

SKU CH-AE5R-DJ6JS

8GB DDR4 2933 ECC registered server memory with 1RX8 rank and 1.35V operation

  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity on dense server platforms
  • 8 GB capacity fits standard DIMM slots for straightforward upgrades
  • DDR4 2933 speed delivers responsive throughput for virtualised environments
  • Low 1.35 V operation reduces power draw and heat output

8 GB DDR4 2933 ECC Registered DIMM

This 8 GB DDR4 module runs at 2933 MT/s with ECC and registered buffering for data integrity. It is built for servers and workstations that require error correction and signal stability under continuous load. The single-rank 1Rx8 organisation keeps electrical loading low on populated channels. Voltage is set at 1.35 V for standard DDR4 power envelopes.

288-pin installation with registered module

The stick uses the standard 288-pin DDR4 form factor and seats in any compatible DIMM slot. Registered modules add a clock cycle of latency and must be paired with a platform that explicitly supports registered memory; they will not function in consumer desktop boards. Mixing registered and unbuffered DIMMs on the same channel is not supported and will prevent boot. Handle by the edges and align the key notch before applying even pressure.

Verify platform support for registered ECC DDR4

Confirm that the motherboard and CPU memory controller list registered ECC DDR4 at 2933 MT/s in their qualified vendor list. The system must accept 1.35 V operation and 1Rx8 density for this capacity. Check the maximum supported capacity per slot and total channel population limits before ordering. BIOS revision may affect recognition of registered modules at rated speed.

商品問答

How do I confirm the module is running at 2933 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode or CPU-Z; both will report the operating speed as 2933 MT/s and show ECC enabled for this registered DIMM.

What comes with the HMA81GR7CJR8N-WM and what must I source separately?

The package contains the single 8 GB 288-pin DDR4 registered DIMM; no cables, brackets or additional memory modules are included, so purchase any extra sticks required to fill your server’s channels.

Should I choose the 1RX8 8 GB version or a different capacity for my server?

Select this 1RX8 8 GB module when your platform needs a registered ECC DIMM at 2933 MT/s with a single-rank layout; match the total capacity to your motherboard’s maximum supported memory and channel population rules.
