Upgrading Ram - National Instruments PXI Series User Manual

Upgrading RAM

Notes National Instruments has tested and verified that the DDR3 SO-DIMMs we sell
work with the NI PXI-8109. We recommend you purchase your DDR3 SO-DIMM
modules from National Instruments. Other off-the-shelf DDR3 SO-DIMM modules
are not guaranteed to work properly.
When installing memory modules into the memory sockets, the lower socket must be
populated first, followed by the upper socket. If a single memory module is used, it must
be installed in the lower socket.

You can change the amount of installed RAM on the NI PXI-8109 by
upgrading the SO-DIMMs.
To upgrade the RAM, remove the NI PXI-8109 from the PXI chassis. To
optimize both memory capacity and system performance, use the same size
and speed memory module in each of the two module slots. The use of
different size modules in each slot is supported, but system performance
will be slower than using two matched modules. However, two mismatched
modules could result in better performance than using a single module.
National Instruments offers the following SO-DIMM for use with the
NI PXI-8109 controller.
