該連結裡面的重點只有這樣：
According to the info we have, the upcoming X48, actually is selected X38 chip.

Of course, Intel push up the performance of the chipset. We all know X48 supports 1600MHz FSB YorkField and Supports DDR3 1600 XMP. Of course Intel finally decide to abandon DDR2.

Because X48 are only an"OC version of X38”,the bug inside X38 still exists in X48. for example, if the computer have a warm reset or S3(post to ram), the PCIe width may reduces. you may experience Such bugs in X48.

挑重點部份翻譯的話是說，X48只是特挑的X38，保證能上FSB1600/DDRIII-1600（特定模組），以及完全醃掉DDRII的支援能力。X38則是晶片組廠商沒保證（至於主機板廠會怎麼玩嘛...嘿嘿），其他該有的不該有的特性都全部繼承。
