Maximum ram for labview

[NTampelloni]

Hello everyone , I was thinking of doing an 8GB RAM upgrade to 16GB of OS WIN7 64Bit to devote more ram to labview .
There is a maximum usage limit of ram labview ?

If you are using the 32-bit LabVIEW, the max RAM is 2GB, just like every other 32-bit application.

It depends on whether you have LabVIEW 32 bit or 64 bit installed.

-To be precise 32 bit can use 4gb and 64 bit Max 16tb.

In order to take advantage of this much RAM, you will need to use the 64 bit version of LabVIEW.

In the past, some add-ons or toolkits did not have a 64-bit version available, so it may depend on your version of LabVIEW as well as Windows.

it depend on your LV version and op bit(64 or 32and also your Windows op bit (64or 32)
but the answer for all of them is yes but if you have version lower that 8.6 yes there 2 gig for 32 and 4 for 64 bit LB
and the most large RAM allocation for LV is belong to win64 LV 64 and version higher than 2009

I should also add that if you actually need this much RAM and you are not doing some MASSIVE image and/or signal processing, then your code needs refactored because you likely have a memory leak.

Thank you all for the replies.

Recapping LV2014 32bit on S.O. WIN7 64bit - can use a maximum of 4GB .
So needless to double the RAM , it would not be used

there's also this 2015 NI knowledge base article:

Depending on what else you have running and what else you use the computer for, Windows might run a little smoother.

Of course it would be used, (just not by LabVIEW!) leaving more RAM for LabVIEW. If your computer only has 4GB of RAM, it needs to be shared with everything else running (OS, etc.) and LabVIEW will not be able to use 4GB.
