Target Server Memory Kit

This 768GB kit contains six 128GB DDR5 RDIMM modules built for the Supermicro H13DSG-O-CPU motherboard. Each stick runs at 4800MHz with CL40 latency at 1.1V and uses a 2Rx4 registered ECC design. The 288-pin form factor matches the board's memory slots exactly.

Fitment And Alternatives

It suits administrators upgrading that specific Supermicro platform to its maximum supported capacity with validated modules. Buyers who need a different total capacity, a UDIMM form factor, or non-ECC memory should look at other kits.

Capacity Decides Suitability

The single specification that determines whether this is the right part is the 768GB total capacity across six 128GB modules. If your server's memory population rules or workload demand a different total, this kit will not match the requirement.

Questions about this item

Should I pick the 6x128GB kit or a different capacity for my Supermicro H13DSG-O-CPU?

The 6x128GB kit provides 768GB total and matches the board's required 2Rx4 registered ECC layout. Verify your motherboard's maximum supported capacity and approved DIMM population order in its manual before purchasing.

What does the DDR5 4800 rating mean once installed in the server?

The modules will run at 4800 MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth. Registered buffering lets all six slots operate at this rated speed when fully populated.

Does the 288-pin RDIMM interface limit the memory speed or capacity on this board?

The 288-pin registered DDR5 form factor is exactly what the H13DSG-O-CPU requires. It supports the kit's 4800 MT/s rating and 128GB per module density when installed per the board's population rules.
