Today we test the new ASRock Z87 Extreme4 Intel LGA 1150 motherboard at OCinside.de. It is based on the Intel Z87 chipset and offers a high-quality solution for current 1150-pin Haswell processors like the Intel Core i7-4770K, Intel Core i5-4570 or the Intel Core i5-4670K, which we have used to test and overclock this motherboard. Surely only a few motherboards can compete with the recently tested ASRock Z87M OC Formula when overclocking, but the basic equipment of the ASRock Extreme series sets definitely new standards. The ASRock Z87 Extreme4 offers for example a total of five PCI Express slots, up to nine USB3.0 ports, eight SATA3 ports, eSATA3, DisplayPort, 15-pin D-Sub, DVI-D, HDMI out, HDMI in and purity sound with digital sound output over an optical S/PDIF output. We may be curious to see all results of the ASRock Z87 Extreme4 in the following review.
