How to allocate Hypermemory on HP635

Ok so I have an HP 635 and I it can allocate up to 512MB of system memory to the GPU (HD4250).

How do I do this? This is a great laptop for basic gaming but it just needs abit of dedicated graphics memory.

Would appreciate any help.
You don't.

Windows 7 does this automatically. If the graphic card requires more memory for whatever task it's working on, it's available from the system (assuming it's not being used by anything else).
