Capacity and purpose

This kit provides 512GB of DDR5 ECC registered memory in four 128GB modules. It is built for ASRock TRX50 WS workstation motherboards that require registered DIMMs for large-capacity stability.

Registered DIMM constraints

Registered modules add a clock cycle of buffering so the memory controller can drive many ranks without signal degradation. The trade-off is slightly higher latency than unbuffered DIMMs and a requirement that the motherboard chipset explicitly supports registered memory.

Build and daily handling

The modules use major OEM Samsung, Micron or Hynix chips on a 288-pin PCB with no heat spreader. Four-rank 4Rx4 organisation fits dense server sockets, while 1.1V operation keeps power draw low for continuous workloads.

Questions about this item

Should I pick the 4×128 GB kit or a different capacity for my ASRock TRX50 WS?

The 512 GB kit delivers four 128 GB modules, filling four slots at DDR5 5600 with CL46 latency and 1.10 V.

What does DDR5 5600 (PC5-44800) actually give me in this workstation?

It runs at 5600 MT/s with CL46 timing, ECC error correction and registered buffering for stable throughput under heavy server workloads.

How does the 288-pin RDIMM interface limit speed or capacity here?

The 288-pin RDIMM form factor carries the 5600 MT/s signal and 4Rx4 organisation, so the platform's memory controller sets the practical ceiling.
