SK hynix HMA81GU6DJR8N-XN_UA 8GB DDR4 3200MHz CL22 server RAM

8 GB DDR4 3200 MHz module

This SK hynix DIMM adds 8 GB of DDR4 memory at 3200 MHz to compatible desktop or workstation boards. The unbuffered, non-ECC design suits standard consumer platforms that accept 288-pin modules. It runs at the JEDEC-standard 1.2 V and carries a CL22 latency rating. Builders upgrading a single channel or populating a vacant slot will find the 1Rx8 organisation straightforward.

Sustained throughput with standard timing

At the rated 3200 MHz the module delivers PC4-25600 bandwidth continuously, limited by the CL22 CAS latency rather than aggressive binning. The 1.2 V operation keeps thermals modest during extended workloads such as compilation, rendering or virtualisation. Because the part is unbuffered and non-ECC, the memory controller handles all refresh and error duties without additional register overhead.

Verify slot type and ECC requirements

Confirm the motherboard accepts 288-pin DDR4 DIMMs and does not require registered or ECC memory, as this stick provides neither. Check that the board supports 3200 MHz JEDEC speeds or will down-clock automatically. Ensure an empty DIMM slot is available and that the platform’s maximum per-slot capacity covers 8 GB. Match the part number HMA81GU6DJR8N-XN_UA against your system’s qualified-vendor list before ordering.
