A-Tech 24GB DDR5 4800 ECC RDIMM 1Rx8 Server RAM

SKU CH-YE6G-QXBZN

24GB DDR5 4800 ECC registered DIMM for server and workstation upgrades

  • Capacity24GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS Latency40
  • Voltage1.10V
  • ECCYes
  • 24 GB capacity handles heavy server workloads
  • DDR5 4800 speed moves data at PC5-38400 bandwidth
  • ECC RDIMM design detects and corrects memory errors
  • 1Rx8 single-rank layout keeps signal timing clean
  • 10 V standard voltage reduces power draw

Server memory upgrade

This 24GB DDR5 module replaces the Samsung M321R3GA3BB0-CQK in compatible servers and workstations. It adds capacity to systems that accept registered ECC RDIMMs running at 4800 MT/s. Buyers who need non-ECC or unbuffered memory cannot use this part.

Registered ECC RDIMM

The module is a 288-pin DDR5 RDIMM with 1Rx8 organisation, CAS latency 40 and 1.10 V operation. Registered ECC buffering is the single specification that determines whether the motherboard and CPU memory controller will accept it.

Straightforward installation

Align the notch with the slot key and press until the latches click; the registered design adds no extra steps. The most common issue is mixing registered and unbuffered modules, which prevents the system from posting.

Questions about this item

What does the DDR5 4800 rating mean once the module is installed in a server?

The module runs at 4800 MT/s with CAS latency 40, delivering PC5-38400 bandwidth when the platform negotiates DDR5-4800 speed.

How does the 288-pin RDIMM interface limit real-world throughput?

The registered DDR5 DIMM uses a 288-pin connector and on-module register, so maximum throughput is capped at the DDR5-4800 data rate the platform supports.

Will this 1Rx8 stick fit a standard DDR5 RDIMM slot without a heat spreader?

Yes — it is a bare 288-pin RDIMM at standard 1.10 V height, so it seats in any DDR5 RDIMM slot that accepts single-rank modules.
