Capacity and Compatibility

This 512 GB kit contains eight 64 GB DDR4 3200 modules built to the PC4 25600 standard. Registered ECC RDIMMs with 2Rx4 organisation and CL22 timing at 1.2 V are designed for Supermicro X12SPT-G and X12SPT-GC motherboards that require registered memory.

Pre-Installation Checks

Confirm your motherboard manual lists the exact 512 GB capacity, approved DIMM population order and 288-pin RDIMM support before ordering. The system must accept registered ECC modules at 1.2 V with 2Rx4 rank configuration to recognise the full kit at rated speed.

Build and Daily Use

Modules use major OEM chips without heat spreaders and rely on the server chassis airflow for cooling. The 288-pin registered form factor locks into the board's RDIMM slots, while on-die ECC corrects single-bit errors during continuous operation.

Questions about this item

Does the kit include all eight 64 GB modules or must I buy any DIMMs separately?

The package contains the complete 512 GB kit with eight 64 GB DDR4 3200 CL22 2Rx4 registered ECC RDIMMs; no additional modules are required.

Should I choose this 512 GB 8 x 64 GB kit or a different capacity for my Supermicro X12SPT-G or X12SPT-GC motherboard?

Select this 512 GB kit when your board's memory population rules allow eight 64 GB 2Rx4 registered DIMMs; otherwise consult the manual for the approved capacity and slot order.

What does the DDR4 3200 PC4-25600 rating mean once the modules are installed in the server?

The memory will run at 3200 MT/s with CL22 latency at 1.20 V, delivering the rated PC4-25600 bandwidth when the motherboard populates all slots with these registered ECC DIMMs.
