Upgrading RAM
You can change the amount of installed RAM on the NI PXIe-8135 by upgrading the
SO-DIMMs.
To upgrade the RAM, remove the NI PXIe-8135 from the PXI Express 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 PXIe-8135 controller.
•
PC3-12800 (DDR3 1600) 4 GB, 256 MB × 64, CL 9, 1.18 in. max
(NI part number 782341-4096)
•
PC3-12800 (DDR3 1600) 8 GB, 512 MB × 64, CL 9, 1.18 in. max
(NI part number 782341-8192)
Note
National Instruments has tested and verified that the DDR3 SO-DIMMs we
sell work with the NI PXIe-8135. 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.
The NI PXIe-8135 removable hard drive variant has a single module slot that supports up to an
8 GB DDR3 SO-DIMM module.
