Server Memory for System X

The IBM 47J0170 is a 16GB DDR3 module built for System X servers that require registered ECC memory. It suits administrators maintaining existing DDR3 platforms where data integrity and registered signalling are mandatory.

Sustained Load Behaviour

Registered buffering and ECC correction keep data stable during continuous workloads such as virtualisation or database services. The module runs at 1333 MT/s with CL9 latency and 1.35V, delivering consistent throughput without the errors that unbuffered memory can introduce over long periods.

Installation Notes

The 240-pin DIMM fits standard DDR3 server slots; the registered design means the memory controller must support registered modules or the system will not post. Buyers who need unbuffered memory or a different DDR generation cannot use this part.

Questions about this item

How much power does the 1.35 V DDR3 1333 module draw when the server runs all day?

At 1.35 V the 47J0170 operates at a lower voltage than standard DDR3, reducing heat output during continuous operation.

What must the system board provide for this 240-pin registered DIMM to function?

The motherboard needs a 240-pin DDR3 slot that supports registered ECC memory and a memory controller able to address 16 GB per module.

Can the 47J0170 be mixed with other DDR3 registered ECC sticks already installed in the server?

Yes, provided the existing modules are also DDR3 registered ECC; the system will run at the lowest common speed and timing across all populated slots.
