32GB DDR4 ECC UDIMM for servers

This 32GB DDR4 2666MHz ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It runs at 1.20V with CL19 latency and a 2Rx8 rank configuration. The unbuffered design suits platforms that do not accept registered DIMMs.

288-pin DIMM with major-brand chipset

The module uses a standard 288-pin DDR4 DIMM form factor with a major-brand chipset for reliable operation. Unbuffered ECC circuitry detects and corrects single-bit errors without adding register delay. Installation follows normal DIMM seating procedures in compatible HP platforms referenced by part number L43758-001.

Tested module backed by lifetime warranty

Every unit undergoes quality-assurance testing before shipment to verify dependable performance. A-Tech includes a lifetime warranty and provides US-based technical support for compatibility questions before and after purchase. Buyers who need registered or load-reduced memory, or capacities beyond 32GB per module, should look elsewhere.

Questions about this item

Does DDR4 2666 PC4-21300 cap the memory bus at 2666 MT/s in a server?

Yes, the module runs at DDR4 2666 MHz (PC4-21300), so the memory bus operates at 2666 MT/s when installed in a compatible server or workstation.

Will this 288-pin DDR4 DIMM fit a standard server UDIMM slot?

The stick uses the 288-pin DDR4 DIMM form factor, which matches standard unbuffered server UDIMM slots; verify your system accepts 2Rx8 ECC unbuffered modules before installing.

What is the correct way to seat the module and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, then confirm the system detects 32 GB at 2666 MHz in BIOS — skipping the clip check is the most common oversight.
