Here's my laptop:
Dell Precision M6500 (Quad Core) Laptop/Notebook
I'm running windows 7, enterprise, 64 bit
According to this I can support up to 192GB of ram: http://www.zdnet.com/blog/hardware/max-memory-limits-for-64-bit-windows-7/4254
Can I put 4x48gb sticks in? What about 2x16gb and 2x2gb? How do I know which combinations are OK?
