PXI Memory UPgrade

Recommended Posts

Has anyone upgraded memory in their PXI systems? Do you buy the way way overpriced NI memory or do you order something from a respectable company like Corsair , OCZ or Kingston. After all it is just laptop memory!

For the controller I had, it would have cost $1000 for 1GB of memory from NI. I carefully researched the memory's specs (available with some digging on NI's site) and bought from Crucial. Worked out just fine.

I *believe* that it is indeed standard laptop memory, but I'm not sure how putting in third-party RAM would effect your NI warranty...

I have a customer that has been doing it (buying laptop memory from Fry's) for 5 to 10 PXI chassis so far. As far as I know they never had any issues.

Note: The first time they did it was about 2-3 years ago, and these systems are still working just fine today.

Good point! So I called NI, and the response was NO it would not affect the NI warranty!!!!

You might also consider that the NI memory will definitely support the extended temperature spec (if you have that option) in harsh environments.

You know, i have ordered stuff with the extended temp spec, and yet i am still unsure what it is that is different! Do you know?

Also, alot of memory these days is designed around "gamers" which tend to have HOTTTT! systems. So one would expect the more

recent memory is capable of withstanding the harsh environment. I have seen analysis enclosures (which contain the pxi system and other electronics) of mine reach 120ยบ F internally without difficulty. All my enclosures have air exchangers, which dont work very well, but my newest one has an AC unit (1000BTU) to keep my precious

NI equipment comfortable!
