ASUS Z87-Deluxe/Dual LGA1150 Intel Motherboard Review

LGA1150 Motherboard UEFI BIOS 2

Overclockers will gravitate to the AI Tweaker section. It’s here that you’ll be able to adjust every CPU, memory, and power setting you’ve ever heard of, and frankly a lot of settings you haven’t heard of!

The main Tweaker page serves as a stepping-off point for the individual sections on the CPU, DRAM, and power adjustments. There are a few general settings at the bottom.

The CPU section has the usual suspects, but bear in mind that what you see on this screen will vary depending on the CPU installed in the system. You won’t be able to adjust the CPU Core Ratio, CPU Strap, or some other settings with non-“K” series CPUs.

I was going to count how many settings you could change on the AI Tweaker RAM page, but I lost count after 20. OK, actually I counted twice and got 49 different DRAM settings, including interesting ones like Scrambler Setting. I’m told that setting this to “Optimized” will improve stability.

Of course, if you’re overclocking, you’re going to need to work with the power settings too. ASUS was one of the first (if not the first) vendor to adopt fully digital power supplies on board with their Digi+ design, and experienced overclockers will be able to make good use of all the capabilities available.

Another cool BIOS feature ASUS introduced on their Z87 line is the concept of a Favorites section. At almost any point in the BIOS, you can press F4 and add that specific setting to the My Favorites page. This makes accessing your frequently-used settings much easier. Here I’ve added CPU Load-line Calibration, 1-Core Ratio Limit, and DRAM Frequency to my Favorites page.

This last item is one of my favorite features: a list of all the settings you’ve changed, before you have to commit to saving them. Ingenious.

I’ll examine ASUS’ new version of AI Suite in the next section.

    Thanks for your Excellent review
    I had read several reviews before buying, and was curious which Ethernet port was the Intel one.
    I just received my new ASUS Z87-Deluxe/Quad motherboard, and it has an “Intel” sticker that covers the top of the ethernet output port (the one closest to the BIOS feedback button), that states in three lines ” Intel Ethernet, Great Capability, GBit LAN”. Then by default, the Ethernet port next to the Analog port is the Realtek port !

    I have recently purchased the ASUS Z87 and just read this excellent review.” I also purchased the Intel i7 4790 processor and question, how big of a deal is it not to have purchased the i7 4790K vs. the “boxed” version. I plan to use the PC for normal every day use and the occasional video editing. Should I really consider returning the i7 4790 for the “K” series? Finally, I am planning to puchase 16GB of RAM at 2133 Mhz.. Is this a smart move when the CPU supports only up to 1600 Mhz even though the motherboard will support much faster RAM?

      The Intel i7 4790K CPU comes unlocked from the factory at 4.4 GHz, while the i7 4790 is locked (not able to be overclocked) and runs at 4.0 GHz. Typically i7 4790K costs about $30 more than i7 4790. If you’re not overclocking, which is an enthusiast activity and doesn’t usually yield significant performance gains, there’s no reason the i7 4790 wouldn’t operate nearly the same as i7 4790K in day-to-day operations.

      As for the memory, the CPU can use RAM faster than 1600 MHz, but usually only if the clock settings are adjusted. With that much system memory you’re likely not utilizing more than 50% even under load, so data strobe cycles matter. Think of it this way: an instruction has to pass through all of the memory before returning to the processor. More memory equals a longer round-trip, but faster memory helps reduce the penalty.

      Personally, I would buy 8GB of 1600 MHz DDR3 and check the system resource monitor tool to see if more was really necessary. Oh- and use an SSD for the primary drive!
