32GB DDR4 ECC RDIMM kit for Supermicro X12SPT-G

This 32GB kit contains four 8GB DDR4 3200 registered ECC modules built to the exact rank, voltage and timing the Supermicro X12SPT-G and X12SPT-GC motherboards expect. The 288-pin RDIMM form factor matches the board's memory slots so the system recognises the full capacity at rated speed.

Suited for admins upgrading these specific

Ideal for administrators expanding memory on a Supermicro X12SPT-G or X12SPT-GC platform where registered ECC RDIMMs are required. Not suitable for systems that accept only unbuffered UDIMMs, laptops needing SODIMMs, or builds targeting a different DDR generation or form factor.

Registered ECC RDIMM architecture decides

The modules are registered (buffered) with on-die ECC and a 1Rx8 organisation, a combination the memory controller on these Supermicro boards requires for stable operation at DDR4 3200. If your platform demands unbuffered memory or a different rank configuration, this kit will not function.

Questions about this item

What DDR4 speed and PC4 rating do these MR25600-818K4 modules run at?

The kit runs at DDR4 3200 with a PC4-25600 rating, so the memory controller operates at the board's supported 3200 MT/s data rate.

What physical slot and form factor do the 288-pin RDIMMs need on the Supermicro X12SPT-G?

They require standard 288-pin DDR4 RDIMM slots; the registered design means they will not fit or function in UDIMM or SODIMM sockets.

What population order should I follow when installing all four 1Rx8 sticks?

Consult the Supermicro X12SPT-G manual for the approved DIMM population sequence; installing in the wrong slot order is the most common reason the full 32 GB is not recognised.
