256GB DDR5-6400 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5-6400 registered ECC modules built for the GIGABYTE MS34-CP0 motherboard. It targets server administrators who need maximum capacity on that specific platform. Buyers who want unbuffered UDIMMs or SODIMM form factors cannot use this product.

2Rx4 registered architecture at 1.1V

The single specification that decides fitment is the 2Rx4 registered (RDIMM) organisation combined with 1.1V operation and CL52 timing at DDR5-6400. Your motherboard must support this exact rank, voltage and registered signalling; a different rank count, unbuffered DIMMs or a mismatched voltage will prevent the system from posting at rated speed.

Straightforward slot population with manual checks

Installation follows the board's documented population order for four RDIMMs; seat each module until the retention clips engage. The most common issue is ignoring the manual's slot sequence or mixing this kit with existing DIMMs of a different rank or voltage, which causes training failures or reduced capacity.

Questions about this item

Will the DDR5-6400 speed run at full rate on a GIGABYTE MS34-CP0 motherboard?

The kit is spec-matched to the board's DDR5-6400 memory controller so all four modules are recognised at full capacity and rated speed.

What does PC5-51200 mean for this RDIMM?

PC5-51200 is the DDR5-6400 data-rate designation; the registered buffer lets every slot run fully populated at that rate.

Do these 288-pin RDIMMs fit the MS34-CP0 DIMM slots?

Yes, the 288-pin registered form factor matches the board's DDR5 RDIMM slots exactly.
