I'd be curious to know what video cards are being used by folks experiencing out of memory (OOM) errors (yep, I can see your video card in your sig, Turnip).At any rate some folks have gained success dealing with OOM's using this from Phil Taylor.Good luck,

Open a command prompt with Administration rights. You find the command prompt box under "Programs->Accessories->Command prompt" or somewhere around there 2. Right Click the command prompt and select "run as administrator". 3. Enter in the box at the prompt: (copy/paste if you wish) bcdedit /set IncreaseUserVA 2560 and press enter 4. Reboot TO set that back to default in VISTA just start the command line prompt with Admin right again and type: bcdedit /set IncreaseUserVA 2048 Hit enter and reboot The first value will tell VISTA to address more memory. It should be used if you have more than 2GB installed, or in some cases 2GB or less. the second line was to restore the default Vista value if it does not work. Make sure you have the updates from Windows Update installed because one addresses PCIe memory mapping as i recall and there are performance updates for Vista posted
