Intel increased the maximum memory capacity of 8 to 16 GB and sat as a Southbridge the new ICH10 a. The P45 and P43 replaced the P35 and P31 of the previous generation and introduced support for PCI-Express 2.0 in the mainstream sector for the first time.

These were the first motherboard chipsets from Intel, which were manufactured using the 65 nm manufacturing process. On July 4th, 2008 at Computex in Taipei, Intel officially presented the first Eaglelake chips, P45 and P43. Intel was criticized for the naming, because from a technical point of view the name X39 would have been more appropriate. Because the X48 still uses the Bearlake core, it is the only chipset in the Intel 4 series that is still manufactured using the older 90 nm process. The latter is necessary for the operation of the Core 2 Extreme QX9770 processor, which can officially only be used on an X48 chipset. However, the X-48 is a new edition of the X38 chipset, to which official support for DDR3-1600 and a front side bus of 1600 MHz has been added. The X48 chipset was presented as the first chip in the Intel 4 series on Maat CeBIT in Hanover.
