The Z68 chipset has now been on the market for some time and just about every well known motherboard manufacturer has adapted its product range accordingly now. ASRock has taken the opportunity and with the Z68 Extreme7 a new high end board to the program taken which has increased compared to previous boards with P67 chipset also in function and features and in which not just the chipset has been replaced. The Z68 Extreme7 Gen3 is designed thanks to the NF200 chip multi GPU mode and can come up with a reasonably good standard. It has also implemented features of the ASRock Z68 how to access the iGPU of the Sandy Bridge central processing units. The Z68 Extreme7 belongs in the base 1155 secure area of the most interesting high end motherboards and we have therefore subjected to a further test.
The ASRock Z68 Extreme7 Gen3 is clearly focused on the use in high end systems. It offers impressive five PCIe x16 interfaces, one of which with built NF200 switch three can be run in parallel at high speed. More than three graphics cards are not on the Z68 Extreme7 because of space to good use so this limitation makes sense on three cards. One PCIe x16 ports provides support for PCI Express 3.0, but what a Ivy Bridge CPU is required.
With the Z68 Extreme7 Gen3 ASRock supplemented its already pretty impressive model range in the base 1155-region to a high end model which with a street price of around compared to direct competitors is also attractively priced.
The Z68 Extreme7 offers powerful voltage converter a very well to use UEFI BIOS and with six USB 3.0 and SATA 6G ports well placed in this discipline. By design it works with its black or charcoal gray color scheme is also very high. ASRock Z68 is when one Extreme7 digital voltage converter which may have a more flexible control of a number of advantages thanks in good design layout. The CPU is powered by eight stages the GPU part in the CPU has its own four-phase supply. ASRock calls this advanced V8 +4 Power Phase Design. Compared to the competition with up to 24 phase CPU power supply is like eight phases listen to something little, but the number of phases now says little about the actual performance. ASRock Z68 Extreme7 implemented in a very powerful CPU supply which should most sophisticated overclocking setups.
On the Z68 Extreme7 total are five PCIe x16 slots to find which of a PCIe x1 slot to be supplemented. In addition even a PCI interface available. The 16 PCIe lanes which the CPU to connect graphics cards allow you expediently only operating two graphics cards which are then connected to each 8 lanes. Using appropriate additional chips, such as the set of ASRock NVIDIA NF200, can this problem but deal. The NF200 is a PCI Express switch that is connected with 16 PCIe lanes to the CPU and then the downstream can represent 32 PCIe lanes available. When using two graphics cards can both run up to full x16 speed, but that in comparison with the native x8/x8-Anbindung in systems without an NF200 chip brings no relevant performance benefits when appropriate analysis on the web are to be believed. Real advantages the concept with the NF200 offers but at three graphics cards as the NF200 switch the available limited bandwidth to the CPU can be optimally utilized. A triple-SLI setup would be operated as 16x/8x/8x.
