Test System Setup and Overclocking




We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital, MemoRight, and Corsair.


With the release of the newer i7-4790K, you have seen us move our Z97 motherboard testing over to it from the i7-4770K that managed to serve us extremely well since launch. Because of the changeover, we have some boards using our older i7-4770K and some using our newer i7-4790K. As we test more and more Z97 based motherboards, you'll see the results of the boards using the i7-4770K get phased out.


So, with that all said and done, the setups that you're going to see in our graphs here today using the newer i7-4790K include the ASUS Z97-A, which will be running at both stock and overclocked, with the latter being discussed in just a moment. Along with that, we also have the recently looked at ASRock Z97X Killer and GIGABYTE Z97X GAMING G1 WIFI-BK Black Edition.


As for motherboards that are using our older i7-4770K, we have three here today, including the two Z97 based offerings from MSI and GIGABYTE in the form of the Z97 GAMING 9 AC and Z97X-UD5H. Along with those, we've also got the Z87 based ASRock Z87 Killer.


As always, before we get into the performance side of things, we have to cover what went on in the overclocking department. Our i7-4790K hasn't overclocked quite as well when compared to our previous i7-4770K, which managed to achieve nearly 5GHz. Our i7-4790K, on the other hand, tends to be sitting around the 4.7GHz mark.




After messing around in the BIOS and tweaking all of our settings, we ended up with our multiplier running at 47x and our BCLK slightly elevated to 101.51. Combined, this results in a final clock speed of 4724MHz, or 4.72GHz as shown in our graphs here today. This overclock is fairly standard for what we're seeing out of our particular i7-4790K. We're hoping that in time we find ourselves with a stronger i7-4790K.
