A-Tech 8GB DDR4 3200 ECC RDIMM

This 8GB registered ECC module runs at DDR4 3200 with CL22 latency and 1.2V operation. It replaces Micron MTA9ASF1G72PZ series parts in server and workstation platforms. The single-rank 1Rx8 organisation uses Micron chipset components on a 288-pin DIMM.

Suits ECC registered DDR4 3200 slots only

This module fits systems that require registered ECC DDR4 3200 memory with 1Rx8 layout. It will not work in platforms needing unbuffered non-ECC memory, different speeds, other voltages, or higher capacities per slot. Laptop SODIMM slots and consumer desktop boards without ECC support cannot use it.

Registered ECC DDR4 3200 1Rx8 at CL22

The registered ECC DDR4 3200 1Rx8 CL22 specification decides compatibility. Verify the motherboard or system manual calls for this exact registered ECC DDR4 3200 1Rx8 CL22 1.2V module before purchase.

Questions about this item

Does my motherboard need a DDR4 288-pin DIMM slot for this 8GB ECC RDIMM?

Yes, this module uses the standard DDR4 288-pin DIMM form factor and requires a compatible DDR4 RDIMM slot on the motherboard.

Can I mix this CL22 registered ECC module with older unbuffered ECC DIMMs in the same server?

No, registered and unbuffered ECC memory types cannot be mixed on the same motherboard; all slots must use registered DIMMs.

How do I confirm the module is running at 3200MHz with ECC active after installation?

Check the system BIOS or use a tool like CPU-Z to verify the memory speed shows 3200MHz and the ECC status is reported as active.
