64GB DDR3L ECC Registered Kit

This 64GB kit contains four 16GB DDR3L 1600 modules built for Intel S2600CO, S2600CP, S2600CP2 and S2600CP4 server boards. Each stick runs at 1.35V with CL11 11-11-11 timings and 2Rx4 registered ECC. It targets administrators who need maximum capacity per channel on these platforms.

Sustained load behaviour

Registered ECC buffering reduces electrical load on the memory controller during continuous operation. The supplier notes that DDR3-1333 modules clock down to 1066MHz or 800MHz depending on the Xeon model and bank population. Quad-rank DIMMs in the first triple-channel bank run at 1066MHz; adding them to a second bank drops speed to 800MHz.

Upgrade context

The platform supports up to 512GB across 16 sockets per CPU or 8 sockets with two CPUs. This kit fills four slots at 16GB each, leaving room for further expansion within the chipset limits. It is not for systems that require unbuffered ECC only or that cannot accept registered modules. Mixing registered and unbuffered ECC is not supported.

Questions about this item

How much power does each 16GB DDR3L 1600 module draw at 1.35V when the server runs continuously?

Each module operates at 1.35V, lower than standard DDR3, reducing power draw and heat in 24/7 server workloads.

Which motherboards must I already have for this 4×16GB registered ECC kit to work?

This kit is validated for Intel S2600CO, S2600CP, S2600CP2 and S2600CP4 server boards with 240-pin DDR3 slots.

Will these 2Rx4 CL11 modules run at 1600MHz alongside older 1066MHz or 1333MHz DDR3 DIMMs I keep installed?

The board will clock all modules to the lowest common speed; mixing 1600MHz sticks with 1066MHz or 1333MHz DIMMs forces the faster kit down to the slower rate.
