According to this report on Digitimes, Intel is delaying the P45 chipset until mid-June due to some compatibility issues with its primary x16 PCIe slot and modern graphics cards.

Intel is delaying the launch schedule of its P45 chipset from originally in May to mid-June, according to sources at motherboard makers.

The delay of the chipset is due to problems over compatibility between the chipset’s PCI Express x16 port and graphics cards, noted the sources, adding that Intel has notified them that the problem should be solved and ready to launch 2-4 weeks behind the original launch schedule.

Some motherboard makers pointed out that the delay will give them more time to clear up their P35 inventory, however, the comparability problem will surely damage Intel’s image over technological development.

Intel will now announce the P45 chipset during Computex 2008, however, actual motherboard shipments will not begin until mid-June, noted the sources.
