Product Brief ® Intel Desktop Board D915GMH Experience the next-generation Desktop PC form factor for the digital home or digital office. ® Intel Desktop Boards based on the Balanced Technology Extended (BTX) form factor and ® the Intel 915G Express Chipset. When the ATX form factor was introduced in 1995, it was difficult to imagine the incredible growth in PC performance that would lead to the complexity of today’s typical system configurations. Processors have grown from 200 MHz to over 3 GHz. Memory Experience the Balanced and storage are many times faster and higher Technology Extended (BTX) capacity. Graphics cards are much more powerful. Chipsets offer many more integrated capabilities. form factor today with These performance and capability increments all ® the Intel Desktop Board come with additional power and virtually everything in the typical system runs hotter. The evolving digital D915GMH, available in two home and digital office usage models continue to versions with ideal features drive the need for incremental performance. At the same time, market interest in smaller form factors for the digital home or the has grown significantly. The challenge of keeping all digital office. the components within their operating temperature range has unfortunately exposed the limitations of ATX, since the technologies required have become increasingly more expensive and noisy.
