Dell :: Can The Studio XPS 1640 Use A Quad Core Processor

I have been pulling out my hair to figure out if it is possible to improve the processor performance of my Studio XPS 16. I did a significant amount of research before buying this Dell model and, all in all, I am happy with my decision. However, I have noticed that the processor is not as capable as the Q9000 that was in my Asus W90 that I sold.

That was the beginning of my research on the chipset (PM45) and socket type (P: 478) of the Studio XPS 16. This matches the Intel Quad Cores and, more specifically, this particular one: INTEL CORE QUAD Q9200 2.4GHZ 12M 1066 CPU.

Dell told me that these Quad Cores are not compatible with the Studio XPS 1640.
