Chapter 2 Installation and ConfigurationNI PXIe-8130 User Manual 2-22 ni.comof the NI PXI Platform Services software included with your controller.System integrators, configuration utilities, and device drivers can use these.ini files.The NI PXI Platform Services software uses the system module driver,chassis driver, and chassis.ini files to generate the PXI systemdescription files (pxisys.ini and pxiesys.ini). Device drivers andother utility software read the pxiesys.ini and pxisys.ini files toobtain system information. For detailed information about initializationfiles, refer to the PXI specification at www.pxisa.org.Upgrading RAMYou can change the amount of installed RAM on the NI PXIe-8130 byupgrading the SO-DIMMs.To upgrade the RAM, remove the NI PXIe-8130 from the PXI Expresschassis. To optimize both memory capacity and system performance, usethe 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 systemperformance will be slower than using two matched modules. However,two mismatched modules could result in better performance than using asingle module.National Instruments offers the following SO-DIMM for use with theNI PXIe-8130 controller.• PC2-5300 (DDR2 667) 1 GB, 128 MB × 64, CL 5, 1.18 in. max(NI part number 780031-1024)Note National Instruments has tested and verified that the DDR2 SO-DIMMs we sellwork with the NI PXIe-8130. We recommend you purchase your DDR2 SO-DIMMmodules from National Instruments. Other off-the-shelf DDR2 SO-DIMM modulesare not guaranteed to work properly.
