8GB DDR4 3200 ECC UDIMM for servers

This 8GB DDR4 3200 ECC unbuffered DIMM is built for server and workstation systems that require error-correcting memory. It operates at 1.20V with a CAS latency of CL22 and uses a single-rank 1Rx8 organisation. The module is a compatible replacement for Hynix HMA81GU7DJR8N-XN and HMAG68EXNEA parts.

DDR4 3200 speed and ECC constraints

The module runs at DDR4 3200 (PC4-25600) and provides ECC protection only on platforms that support unbuffered ECC UDIMMs. Consumer desktop chipsets typically ignore the ECC function or refuse to boot with ECC modules installed. Maximum bandwidth and error correction are limited to the DDR4 3200 standard and the CL22 timing.

Verify 288-pin DDR4 slot and ECC support

Confirm that your motherboard has DDR4 288-pin DIMM slots and explicitly supports unbuffered ECC memory in its specification list. Check the qualified vendor list for 1Rx8 modules at 3200 MT/s and 1.20V. Systems limited to non-ECC or registered DIMMs will not work with this module.

Questions sur cet article

Should I pick this 8 GB module or look for a different capacity?

This listing is a single 8 GB DDR4 3200 ECC UDIMM; add one module per available slot to reach your desired total memory.

What does the 3200 MHz rating deliver in a live server?

The module runs at DDR4 3200 with CL22 latency at 1.2 V, providing the rated speed when the platform supports that frequency.

Is the DDR4 3200 interface limited by the UDIMM form factor?

The 288-pin UDIMM is unbuffered ECC, so the memory controller drives it directly without a register, capping maximum capacity per channel to the module density.
