SYMPTOMS

You cannot use Connectix RAM Doubler to improve Virtual PC for Mac performance.

CAUSE

This issue occurs because RAM Doubler does not provide more usable memory for a Virtual PC virtual machine. To allocate memory in Virtual PC, you must use real physical memory, not virtual memory that RAM Doubler creates.

Microsoft does not recommend that you use RAM Doubler with Virtual PC for Mac, even if you have a large physical memory.
