Regain the Memory!!!!

Regain the Memory!!!!

Regain the Memory!!!!

(OP)
Morning all,

I've done some searches but can't track down exactly what I'm looking for. I'm running Windows 7 64Bit, 8GB RAM, quad core graphics/processor (AMD) & NX 7.5 and when I'm opening large models I appreciate it uses a lot of memory. My problem is, I am opening small bits of the assembly at a time to find stuff! (Long story) But when I close those bits of the assembly my memory usage still shows high, and obviously gets higher and higher the more I open.

The usage only drops when I close the whole assembly, is there a way that after closing parts of the assembly I can regain that memory? Therefore avoiding potential memory failures.

Hope this makes sense!

Cheers in advance!

RE: Regain the Memory!!!!

I suspect not. However, there are a couple of Assembly Load Option settings, such as toggling ON 'Partial Loading' and using 'Lightweight Representations', which will mitigate this issue somewhat.

Now if you'd like to stop at some point during this process of opening and closing Components and work on your Assembly and you'd like to 'recover' as much memory as possible, you could try this procedure; when you get to where you'd like to start working after your step-by-step process of opening Components is complete, just save a 'Bookmark' of your Assembly, then close the Assembly but instead of reopening the Assembly Part file itself, simply open the 'Bookmark' instead. I'm not sure how much help this will be, but it should help some.

Brilliant, thanks John that works fine!

RE: Regain the Memory!!!!

I have a set-up similar to what is mention above, with 8GB RAM, and have similar concerns with speed.
Does increasing the amount of RAM usually help this situation out ?

RE: Regain the Memory!!!!

We generally recommend that you get as much RAM as is practical and while 8Gb is pretty normal, we just replaced many of our older 4/8Gb laptops with 16Gb systems. Also, I would recommend replacing your hard-drive with an SSD, Solid-State Drive, as that will really speed things up (I will never go back to using a system without an SSD).

Yeah I've maxed my laptop at 8GB. We have some boxes in the office with 16GB, but even they struggle with the big stuff we have to open just recently.

Next system build, which could be soon going to go for as much RAM as I can!

RE: Regain the Memory!!!!

Don't overlook the option of upgrading to an SSD, you'll be amazed as to how much faster NX starts. Even from a cold system, NX 8.5 starts on my HP EliteBook 8570W, with 16Gb memory and 500Gb SSD, in about 24 seconds. Warm starts are under 9 seconds.

I-Deas used to have a command (I think it was a hidden or maybe not) but is was a memory cleanup up command. I do not know exactly how it worked but you could hit this command during a long I-Deas session and in task manager you could see the memory usage drop by 5 to 10%.
