Unable to allocate memory for subdivide cache

[Henry Blewer]

I updated everything I could think of. I get this error when I render over 1280 pixels wide.

Hi,

When I tried rendering your file at 2000 pixels wide I found it did sneak up over 2 GB of memory used. If you are using a 32 bit version of Windows, couldn't easily tell from your log, and you haven't done whatever you need to with the /3GB switch ( hazy on that myself, one of the others will hopefully know more about it ) then you could run out of memory as the error is suggesting. That's what has happened, TG2 is unable to allocate any more memory.

Regards,

Jo

I am using the 32 bit version. I don't know about the 3 GB switch either.
I'll try a render without having ray traced objects. I'll run it over night while I am working. I guess a new computer is becoming more critical.

Is it the same in Vista? I'll try to find information on the Microsoft website. I have been thinking about doing a re-install of Vista anyway.

I found an article on how to change the address memory space in Windows Vista.

I will try this out Tuesday morning after work. I'll let you guys know what happens, sometime... It depends on whether I need to do a re-install of Vista. (I have been thinking about doing this anyway. Too much junk...)

Njeneb , did you think about going 64 bit ?. There are some little problems. But in the long run it is the way to go in my opinion.

I upgraded from XP to Vista with the upgrade, not the full Vista. I may re-install Vista as 64 bit, but this may not work over 32 bit XP. I need to visit and search some forums on this. When I get done here spouting my words of techno babble, I am going to try to change the seeting of the BCD to access 3 GB. I'll let everyone know how this turns out, eventually.

[Henry Blewer]

Ok, the computer is still running. The command from the command prompt (run as administrator) is 'bcdedit /set IncreaseUserVa 3072'
To change the value back, command prompt (run as administrator) 'bcdedit /deletevalue IncreaseUserVa'

Now to try a render and see what happens. Stay tuned folks, njeneb's in for a bumpy ride! (should know something tomorrow)

Look forward to seeing this.

8 hrs 21 mins later. The dot calculation has just finished. So at least I now know the system is still stable. It may not be finished until after I go to work at midnight. At least so far so good.

I hope this isn't considered crashing (the party) but I got a similar error this morning on my overnight render.
Running on 32 bit XP with the /3GB switch, 8GB RAM and 3,2GHZ quad core (AMD Phenom2).
The "starfield" rendered in 30 minutes and that sent me off to bed, smiling and very content about the new machine.
Rude awakening this morning when I saw the errors.

You can still run out of memory with the /3GB switch. 8GB of memory is being sadly wasted with a 32 bit OS. Are you dual booting, or do you not yet have a 64 bit OS? Upgrade recommended ASAP!

I know that the /3GB switch will make XP handle a max of 4GB but the 8GB RAM is there for future use with a 64 bit OS. I'm thinking of Win7 but how to convince the misses? The recent system upgrade used up all goodwill and money
