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

SKU CH-XHZR-2SFC7 MPN HMA81GU6DJR8N-XN_UA

8GB DDR4 DIMM running at 3200MHz with CL22 latency for desktop systems

  • 8 GB capacity supports everyday multitasking
  • 3200 MHz DDR4 speed enables responsive data transfer
  • CL22 latency provides stable timing performance
  • 2 V operation reduces system power draw
  • 288-pin DIMM fits standard desktop memory slots

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.

商品問答

Does the 1.2 V DDR4 module run hot or draw extra power during all-day server workloads?

The module operates at the standard 1.2 V DDR4 voltage, so power draw and heat stay within normal JEDEC limits for continuous operation.

What motherboard slot and chipset support are required to run this 288-pin DIMM at 3200 MHz CL22?

It needs a DDR4 288-pin DIMM slot and a platform that can run PC4-25600 speeds; the memory controller must accept non-ECC unbuffered modules.

Can this non-ECC 1Rx8 stick be mixed with registered ECC DIMMs already in my server?

No — registered ECC and unbuffered non-ECC DIMMs use different signalling and cannot be used together in the same system.
