Server-grade DDR3 ECC RDIMM kit

This 32 GB kit contains four 8 GB DDR3 1600 modules built for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. It targets administrators upgrading workstations, servers, NAS units or routers that require registered ECC memory. Standard desktop systems cannot use these modules.

Registered ECC with 1Rx4 organisation

Each 240-pin DIMM runs at PC3-12800 speed with CL11 latency at 1.5 V and implements 1Rx4 registered ECC. The registered buffer and error-correcting code are mandatory for the listed Supermicro platforms; unbuffered or non-ECC memory will not function in these boards.

Straightforward DIMM installation

Modules insert vertically into the 240-pin slots without tools or heat spreaders to obstruct adjacent components. The only common issue is mixing registered ECC with unbuffered DIMMs or populating slots in an order the motherboard manual does not support, which prevents the system from posting.

Questions about this item

What does the DDR3 1600 speed mean for my Supermicro X9SRG system?

The modules run at 1600 MT/s with CL11 timing on a DDR3 platform, delivering the rated throughput for each populated slot.

What does the PC3-12800 rating cap in practice?

PC3-12800 is the JEDEC DDR3-1600 standard; the kit will operate at that speed on the listed X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards.

What physical slot and clearance do these 240-pin RDIMMs need?

Each module is a 240-pin DDR3 RDIMM without a heat spreader, so it fits standard DDR3 DIMM sockets on the compatible Supermicro boards.
