Installation and Configuration
3.
In the Devices and Interfaces tree, expand PXI System. Your PXI Express chassis is
already identified and appears in the PXI System tree.
4.
For each unidentified PXI Express chassis in the PXI System tree, right-click on the chassis
and select the appropriate chassis model through the Identify As submenu. Further
expanding the PXI System branch shows all devices in the system that NI-VISA can
recognize.
The PXI Express specification allows for many combinations of PXI Express chassis and system
modules. To assist system integrators, PXI Express chassis and system module manufacturers
must document their products' capabilities. PXI Express devices must provide a driver and/or
file for identification. For NI PXI Express chassis and controllers, these files are provided
.ini
as part of the NI PXI Platform Services software included with your controller. System
integrators, configuration utilities, and device drivers can use these
The NI PXI Platform Services software uses the system module driver, chassis driver, and
files to generate the PXI/PXI Express system description files (
chassis.ini
and
). Device drivers and other utility software read the
pxiesys.ini
files to obtain system information. For detailed information about initialization

files, refer to the PXI Express specification at
Upgrading RAM
You can change the amount of installed RAM on the NI PXIe-8880 by upgrading the
SO-DIMMs.
To upgrade the RAM, remove the NI PXIe-8880 from the PXI Express chassis. To optimize
memory capacity and system performance, use the same size and speed memory modules. The
use of different size modules in each slot is supported, but system performance will be slower
than using three matched modules. However, three mismatched modules could result in better
performance than using a single module.
National Instruments offers the following SO-DIMM for use with the NI PXIe-8880 controller.

PC4-1866 (DDR4 2133) 8 GB, 1 GB × 72, CL 15, 1.18 in. max
(NI part number 783813-01)
National Instruments has tested and verified that the DDR4 SO-DIMMs we
Note
sell work with the NI PXIe-8880. We recommend you purchase your DDR4
SO-DIMM modules from National Instruments. Other off-the-shelf DDR4
SO-DIMM modules are not guaranteed to work properly.
