division. The unit was built on the foundation of a Precision M90 chassis. Later models offered the Core 2 Duo processor, the Nvidia GeForce 7950GTX GPU, and optional Blu-ray and/or an unlocked Core 2 Duo processor, which could be overclocked "officially" to 3.16 GHz, although at least 3.5Ghz has been reported as possible. As the mainboard used the Intel 945 chipset, the XPS M1710 could not address more than 3.25 GiB of RAM though Dell specified "up to 4 GB RAM". This computer was replaced by the XPS M1730. The chipset although capable of AHCI operation was never implemented by Dell, leaving any future SATA hard drive upgrade paths crippled to IDE legacy operation, protocols, and bandwidth. Further evidence of untapped capacity involves the use of replacing the video cards with a Dell Precision Quadro FX 1600M (essentially an 8700M GT with comparable performance to the flagship DX9 7950 Go GTX card), allowing for DirectX 10 functionality in a laptop not designed to do so (with the card being unidentified, but the LCD verified by the BIOS, leaving argument that some design foresight was in place for at least a path to using the Quadro FX 1600 and even FX 3600M in this machine in a BIOS revision). Note that there are severe overheating problems with the graphics card in this model., and just like the Precision M90, GPU failures due to cracking in the type of solder used on the Nvidia chipsets to bind them to the substrate were common, and settled via a class-action lawsuit with Nvidia in later years. XPS M1210 A high performance ultra-portable (12.1-inch screen) notebook featuring a new case design, Intel Core Duo processor technology, an optional dedicated NVIDIA GeForce 7400 Go video card and an optional integrated web camera (1.3 megapixel). The M1210 also has optional WWAN (wireless wide area networking) features supporting 3G broadband services. With the standard battery, the laptop weights 1.9 kilograms. Unlike other 12-inch notebook computers, the M1210 features a built-in optical drive rather than an external. This model was discontinued as of July 31, 2007. Gen 2 Inspiron XPS Gen 2/XPS M170 (2005) – This successor to the Inspiron XPS, had replaced the desktop Pentium 4 with a Pentium M processor, which provided almost the same level of performance as the desktop Pentium 4 and reduced the weight from 9.06 lb to 8.6 lb. It featured a 17-inch
