Exact-match server upgrade

This 48 GB DDR5-5600 registered ECC module is built to the precise rank, voltage and timing the Supermicro H14SST-G memory controller expects. It installs as a single 288-pin RDIMM so the board recognises the full capacity at rated speed without manual tuning.

Enterprise stability under load

Registered architecture offloads the memory controller, allowing every populated slot to run at 1.1 V and CL46 while ECC corrects single-bit errors on the fly. The design prevents silent data corruption and unplanned reboots during sustained workloads.

Verified fitment constraint

Compatibility is limited to the Supermicro H14SST-G motherboard and its defined population rules; other boards, form factors or unbuffered memory types are not supported. Consult the system manual for approved DIMM order and maximum capacity before purchase.

Questions about this item

How do I install this 48GB DDR5 5600 RDIMM in my Supermicro H14SST-G and what step do people often miss?

Power down, open the chassis, and insert the 288-pin module into the slot specified by the motherboard manual for your population order; the step most often missed is checking that manual first to confirm the correct slot sequence for 2Rx8 registered DIMMs.

What maintenance or replacement will this ECC registered memory need over time?

No routine maintenance is required; the module either passes POST and runs error-free or it develops correctable ECC events that warrant a replacement under the lifetime warranty.

What limit appears first when this 1.1V CL46 kit runs sustained workloads on the H14SST-G?

The memory controller's maximum supported speed of 5600 MT/s is the first ceiling; the module is rated for that speed at 1.1V, so sustained use stays within spec without thermal throttling.
