ASRock Z270 Extreme 4

3rd January 2017
Type Motherboard
Price $149.99 US

Test Setup

For testing, we used the latest Intel Core i7-7700K processor which we I had acquired with the help of a board manufacturer. The sample is retail ready and not an "ES" chip like the ones sent out by Intel to reviewers. Intel did not contact us or provided NDA for testing of their Kaby Lake processors. Our review is based purely on fact and precision. We also updated our test rig for the 200-series platform review which is listed in the table below:

I would personally like to thank G.Skill for arranging a stunning DDR4 memory kit for this review. They shipped us with a TridentZ series memory (Black and White Color Combination). The memory kit comprises of 2 DIMMs that operate in dual channel mode, ideal for our Z270 board tests. The memory is clocked at 3600 MHz which is supported by the new motherboards since they support XMP profiles. Clock timing is set at 16 and the capacity is 16 GB for this specific kit.

We won't be focusing on Intel's Core i7-7700K architecture in this review since it is entirely the same chip as Skylake along with minor improvements. The Skylake / Kaby Lake architecture analysis can be seen in detail here.

Intel Core i7-7700K 4.7 GHz Overclock on ASROCK Z270 Extreme 4

Our Intel Core i7-7700K isn't a decent overclocker as it requires voltage over 1.35V for a decent clock speed bump. Here, we overclocked the chip to 4.7 GHz (bus speed = 100 MHz x 47.0 Multiplier) using a voltage of 1.350V. The results were stable after testing in Prime95 as a stability run.
