need to install vista 64bit instead of 32bit - any expeience? (on P300 - 4GB ram)

Hi, After checking the NX6 (Cad application) on LGP300 with 4GB and Geforce 8600 - I came to the conclusion that "out of memory" messages comes when NX reaches the maximum allowd for the 32Bit. I Ran the same file with the 64bit version on HP mobile workstation (4GB, 512 dedicated memory on Quadro 770) and although all operations ran even slower then the P300 - the main problem of memory vanished. When examining the memory behaviour it seams that NX on HP with the same file utilize 1.8GB of ram (from the 4GB installed) and goes up to 2.2GB. failure on P300 usually appears on 1.3GB with the 32Bit, but I can't tell what exactly causes the failure. if its the shared memory (any way to lock this sharring) or is it just the application starved for more memory. in any case - I would like to examine the 64Bit on the LG which means giving up all the goodies came with the laptop - and reinstall them after the fresh 64bit. I will need to know how to backup and return to 32. take into account I don't have a recovery CD, only what came with the laptop itself. I would appriciate if someone who actually did this will link a direction. Thanks

 

Before you get going, have you tried increasing your virtual memory and seeing if that resolves the error? I suggest this before the hassle of setting up another OS because you'll only be getting another 1GB of memory AT MOST for the OS (4GB is the max for a 32-bit OS, but usually it only addresses roughly 3-3.5GB). One other thing to note is the maximum that any 32-bit application can address at once is 4GB, so unless you have a 64-bit version NX6, upgrading to a 64-bit OS is totally pointless.

Anyways, increasing pagefile:
You can do so by going to the control panel -> System and then clicking on "Advanced System Settings" on the right. Click on the first "Settings..." button, and then under the advanced tab you'll see a "Change..." button which allows you to modify the size of the page file. Try setting the page file to start at perhaps 256MB and then let it max out at around 4096MB (4GB). Make sure you click the "Set" button otherwise it won't save your changes. Restart and try to make NX6 crash with the out of memory thing.

 

Your P300 should have the LG recovery prompt when you boot (at least my P310 does). This means your recovery for the 32bit OS is currently stored on the HD so you don't need a disk. I would test this out and see if you can recover the 32BIT OS before formatting.

Alternatively, you can always use a ghost program to back up your HDD as it is now, so if things go south you can ghost it back in.

Also, I've tried using the Windows 7 64-BIT with adobe premiere and photoshop 64-bit versions and the improvement is stellar. The extra memory makes a huge difference when it's available. Good luck!

 

I will try that - Maybe its something I've skipped - good idea !!!

 

Do they sell Windows 7 64 already? I thought its only beta...

 

Well - I think this suggestion was a good one - since it resolved some of the issues (not all) - first - I didn't get the error coming so fast, but second it did apear after some work. What I don't understand is if the page file can use more then 8GB and how. I tried applying 256-4080 to both (C, D) partitions. I don't know why this automatic windows is not doing it by itself - but it did do something. I'm not sure if its possible to increase it to 16GB or more, it says not more the 4GB is possible for virtual memory on each disk. any idea?

 

Glad you found some success. I don't know why there's a 4GB limit, but it certainly sounds like you'd benefit from a workstation with a 64-bit OS and a crapton of RAM. Pagefile is painfully slow sometimes (well, okay, all the time).
Are you dealing with giant drawings or something? 8GB seems like a lot for a program to max out. Perhaps there's a memory leak or something somewhere that isn't patched...

 

I'm not sure its a leak - but the vista 64bit on HP with 512 Quadro dedicated ram did pass the test which the 32bit on geforce 256 shared didn't. if theres' a way to block this "shared" issue - I would suggest that might be the leak. no patches I know of - but the P300 is not a recomended laptop for NX, they usually support the large heavy and quite bold machines (something like certified machine from NX software). I was hoping some relations between the on board and Nvidia have been resolved. I suspect the shared memory more then the Virtual memory to be the problem. but again - it might be just the combination of 32bit and shared.

 

with the good help of LG labs - Fresh disk and fresh install of 64Bit vista - everything works good until now. memory problems vanished. Thanks for all people helped on this.

 

Glad to see you got things going correctly
