This document provides the RAM specifications for PXI embedded controllers. You can change the amount of installed RAM on NI PXI controllers by upgrading the SO-DIMMS.
National Instruments has tested and verified that the SO-DIMMs we sell work with the controllers listed below. We recommend you purchase your SO-DIMM modules from National Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work properly.
Notes for controllers with capacity for multiple memory modules:
- 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.
- 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.
Select the controller model from the list below for more information regarding RAM upgrades offered through National Instruments.
Note: RAM upgrades may be unavailable for controllers that have been given end of life status. Contact National Instruments for more information.
