Upgrade Information
How do I upgrade system memory?
You can change the amount of installed RAM on the NI PXI-8104 by
upgrading the DDR2 SO-DIMM.
To upgrade the RAM, remove the NI PXI-8104 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 will result in better performance than using a single module.
National Instruments offers the following types of SO-DIMMs for use with
the NI PXI-8104 controller.

Note
National Instruments has conducted thermal testing as well as mechanical shock and
vibration testing, and has verified that the DDR2 SO-DIMMs we sell work with the
NI PXI-8104. We recommend you purchase your DDR2 SO-DIMM modules from
National Instruments. Other off-the-shelf DDR2 SO-DIMM modules are not guaranteed to
work properly.
