ASUS P7P55D-E Pro Motherboard
DESCRIPTION: The Intel P55 platform has been with us for a good while now, and it is a real sleeper, having the memory controller integrated with the CPU gives it a nice performance advantage over competing products, even higher priced ones. If it has any serious shortcomings, it’s the number of PCI-e lanes that it supports. With a maximum of 16 lanes of PCI-e 2.0 available for graphics cards, there is no room for expansion, if additional devices require PCI-e 2.0 connectivity. Guess what the most common support chips for SATA 6Gb/s and USB 3.0 require? You got it, PCI-e 2.0. ASUS works their way out of this problem on the P7P55D-E Pro motherboard with a PCI Bridge from PLX Technology that takes some spare PCI Express 1.1 lanes, converts them into the required PCI-e 2.0 version, and serves them up to the latest NEC and Marvell controllers. Benchmark Reviews was intrigued by this latest combination and we’re pleased to present a review.
