On 27 July when Intel announced its Core 2 Duo CPU lineup based on the Intel Core microarchitecture, the chip giant did not yet start shipments of its G965 chipset that may later appear as the chip giant's first chipset with DirectX 10 integrated graphics processor (IGP), according to unspecified motherboard makers in Taiwan.

The makers expected Intel's C-1 stepping of the G965 to be ready for volume shipments at the same day with the launch of Conroe processors. However, a defect in the integrated graphics subsystem was found, and Intel notified its customers that next stepping, called C-2, which fixes the flaw, will likely not be shipped until the middle of August, the makers indicated.
