64GB ECC UDIMM kit for servers

This A-Tech kit delivers 64 GB of DDR4 3200 ECC unbuffered memory across four 16 GB modules. It is built for servers and workstations that require error-correcting UDIMMs and is not compatible with desktop or laptop computers.

1.2V standard voltage operation

Each module runs at the DDR4 standard 1.2 V with a CL22 latency and single-rank 1Rx8 organisation. The kit conforms to PC4-25600 specifications for typical server workloads.

Lifetime warranty and US-based support

A-Tech backs every order with a lifetime warranty and provides complimentary United States based technical support before, during and after purchase. All modules undergo quality assurance testing for dependable performance.

Questions about this item

How do I install the four 288-pin UDIMM modules and what step is often missed?

Power off the server, open the chassis, align each module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 64 GB are detected at 3200 MHz; the step most often missed is seating every module fully so both clips engage.

What maintenance or replacement will this 1.2 V DDR4 ECC kit need over time?

No scheduled maintenance is required; keep air intakes clean so the modules stay cool, and replace a stick only if the system logs an uncorrectable ECC error or fails to recognise the 16 GB capacity during POST.

What limit appears first when the 1Rx8 CL22 memory runs under sustained heavy load?

The CAS latency of CL22 at 3200 MHz sets the timing ceiling; under continuous bandwidth-heavy workloads the fixed 22-cycle access delay becomes the bottleneck before thermal throttling on these 1.2 V single-rank modules.
