Sources at motherboard makers say Intel will officially release its 4-series chipsets at Computex 2008.
Initial 4-series chipset shipments will consist of the P45 and P43, for which the previously reported PCI Express compatibility bug has been fixed already. However, the G45 and G43 IGP versions will be delayed for another 2-3 weeks while Intel works to correct issues with VC1 hardware decoding and to increase the graphics core frequency to 800MHz.
Enterprise-based Q45 and Q43 chipsets are also to see a 2-3 weeks delay due to system instabilities found in the current B2 versions when VT-d is active. A3 versions of the chipsets are expected to start shipping in the second week of July.
