Exact-match DDR5-4800 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5 4800 modules rated CL40 at 1.10V. Each stick is a 288-pin 2Rx4 Registered ECC RDIMM built with major OEM chips. The Registered architecture lets the Supermicro H14DSG-OM motherboard run all slots fully populated at rated speed while ECC corrects single-bit errors on the fly.

Verify board population rules first

Check the Supermicro H14DSG-OM manual for supported capacities per slot, approved DIMM population order, and any BIOS version requirements before ordering. The board requires 288-pin RDIMM modules — not UDIMM or SODIMM — and population rules change with CPU count and memory-channel layout. Confirm the eight-module configuration matches your processor installation and channel-filling sequence.

Replaces partial or mixed-capacity sets

The kit upgrades from smaller Registered ECC kits or mismatched modules that force the controller to downclock or limit capacity. Moving to a validated eight-module 512GB set restores full-channel bandwidth and eliminates rank-mismatch errors. The jump is worth it when your workload needs maximum registered capacity and you want a single part number qualified for this exact motherboard.

Questions about this item

What does the 512GB 8x64GB kit include and is anything else needed to install it in a Supermicro H14DSG-OM?

The kit contains eight 64GB DDR5 4800 CL40 2Rx4 1.1V 288-pin ECC Registered RDIMM modules. No extra parts are required; the modules plug directly into the motherboard's DDR5 RDIMM slots.

Why choose the 512GB 8x64GB DDR5 4800 CL40 2Rx4 ECC RDIMM kit over other capacities for the Supermicro H14DSG-OM?

This kit matches the board's DDR5 RDIMM requirement, registered architecture, 2Rx4 rank, 1.1V voltage and CL40 timing so all eight slots can be populated at the rated 4800 MT/s speed.

What does the DDR5 4800 (PC5-38400) rating mean once the modules are running in the server?

The modules operate at 4800 MT/s with CL40 latency at 1.1V, delivering the bandwidth and error-correcting stability the Supermicro H14DSG-OM memory controller expects when fully populated.
