"Out of Memory"

[teookie]

Someone in my group runs into this error at least once a day. If any of us is working on a large assembly it will happen repeatedly. Making drawings is particularly painful. We have been hounding on management to give us better hardware and a 64bit OS for YEARS now but they keep finding "reasons" to ignore us. I'm turning to you guys for some help.

Our existing hardware/software is:
Dell Precision M4500 mobile workstation
Intel Core i7 740QM
8GB RAM
Nvidia Quadro FX 1800M
WinXP 32 bit :-(
NX 6.0.5.3

And I don't know if it matters or not but since we are working at our customers facitily, we have to use VPN to access our network resources.

Question: Will moving to Win7 64bit solve our "our of memory" error problem? Or are our computers lacking in some other area as well? (Management wants to KNOW that better hardware will fix the problem before they will allocate funds.)

ANY help or advice would be appreciated.

Thanks.

Win7-64 should solve your problems. You have 4GB of wasted memory running Win7-32.
VPN conections are a known bottleneck. I ran tests with another CAD system a few years ago and performance jumped when I was connected directly to the network instead of through the VPN connection.
Hopefully the NX software is loaded locally on the laptop and you are only using the VPN connection for a license and to obtain files from a server.
You may find a speed increase if you borrow a license for your laptop and copy the files needed from the server, then disconnect from the VPN to do your work.

We are running Win7 64bit and still get out of memory errors on assemblies of about 400 components (file sizes of 50Mb-125Mb). Doubling the RAM and paging file size didn't help. The hard drive has 50GB of free space. When the task manager shows the peak working memory is approaching 3gig, we know we'll be lucky to get one more save before crashing.

Do you have the 64bit version of NX installed? It sounds like you have only installed 64bit OS but are running NX 32bit. Look in task manager and see if the image name has a *32 after it.

I agree with Ben, sounds like a 32 bit version of NX on a 64 bit OS.

Since we switched from XP 32 ( we were running with the 3Gb switch on) to Win 7 64 , the "out of memory"and "memory access violation" has more or less disappeared. It can still show up, but then not due to memory limits.

You can also see the 32/64 information in the NX syslog, go Help - NX log file... It will be listed above the line "Processors" in the start of the file.

Thanks everyone for chiming in. I will have to check to make sure that when we move to Win7 64 later this year that we move to a 64bit version of NX as well.

I will pass this info along to our IT folks.

For now, make sure that you're using 'Lightweight' Reference Sets and have set Partial Loading when you open your assemblies, whether you're running the 32- or 64-bit version of NX.
