Overclocking
The particular Intel Core i7 4770K chip we used to review the trio of motherboards in the graph below is only capable of 4.8GHz. Any higher and the required voltage causes it to overheat even with a Corsair H100i running in performance mode. The ASRock Z87M Extreme4 was more than capable of hitting that target with 1.29 volts. Of course results will vary depending on your CPU but what these results show is that you won’t be limited by the ASRock Z87M Extreme4, only your chip will hold you back.

“Six SATA III ports are provided all via the Z87 chipset. There is also an eSATA port on the rear I/O which shares bandwidth with SATA port SATA 3_1.” That’s a bit misleading. The user manual does say that the eSATA port has port multiplying capability. But it goes on to say later that if you plug something into the eSATA port, then internal port SATA 3_1 will stop working. That’s exactly what happens. When my kids were little and one took a toy away from the other, we called it the opposite of sharing. Other reviews said that if you use both at the same time, performance would be limited to the speed of one port. I don’t think anybody who is reviewing this is even trying to share that port.
