Fluid simulation still crashes after RAM upgrade

Hello everybody,

I’m running Blender 2.65a 64 bit on my Win. 7 Pro 64 bit PC.

I decided to upgrade the RAM from 12 GB to 24 GB (the max. my i7 970 CPU can handle) in order to bake at higher resolutions.

The problem I’m having is:
It’s as if Blender (or maybe Windows) is still only using 12 GB of RAM.

If I increase the resolution to a higher value than before the upgrade (about 8 GB) Blender crashes. :frowning:

Both the BIOS and Windows are listing 24 GB of installed RAM.

PC specs:
Motherboard: Asus Rampage III Black Edition
CPU: i7 970 3.2GHz 6 core
RAM: 24 GB Corsair Vengeance CMZ12GX3M3A1600C9 (two kits of 3x4 GB)

Well at least you know it’s not a RAM issue. Tell a little bit more about the fluid sim / domain, or better yet just post the blend.

I had the same problem with Kingston RAM’.s Upgraded to 2 8GB Corsair RAM’s and everyhin was fine as clockwork.

What led you to believe that the problem was available physical system memory, in the first place? If you run out of physical memory, windows should provide the required amount in the form of (harddisk-based) swap memory, causing your system to run very slowly. Only if you also run out of swap space should Blender crash, but Windows itself would then also alert you of that fact.
