The Asus ROG Strix Z270G Gaming Test Bed 

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency/monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

We found that the Asus ROG Strix Z270G Gaming has the multi-core acceleration enabled and the FCLK frequency is set to 800 MHz by default. The BIOS states that, in theory, the maximum turbo frequency of our CPU would be 4.5 GHz, yet it maxed out at 4.4 GHz during our default multi-core testing. All of the current/temperature limiters are also enabled by default. There is nothing out of the ordinary here.

Test Setup

4 Cores, 8 Threads, 4.2 GHz (4.5 GHz Turbo)
Motherboards Asus ROG Strix Z270G Gaming
Cooling Alphacool Eisbaer 240
Power Supply Corsair AX1200i Platinum PSU
Memory G.Skill DDR4-2400 C15 2x16 GB 1.2V
Memory Settings XMP @ 2400
Video Cards MSI GTX 770 Lightning 2GB (1150/1202 Boost)
Hard Drive Crucial MX200 1TB
Case Open Test Bed
Operating System Windows 7 64-bit SP1

Thank you to Crucial for providing us with MX200 SSDs. Crucial stepped up to the plate as our benchmark list grows larger with newer benchmarks and titles, and the 1TB MX200 units are strong performers. Based on Marvell's 88SS9189 controller and using Micron's 16nm 128Gbit MLC flash, these are 7mm high, 2.5-inch drives rated for 100K random read IOPs and 555/500 MB/s sequential read and write speeds. The 1TB models we are using here support TCG Opal 2.0 and IEEE-1667 (eDrive) encryption and have a 320TB rated endurance with a three-year warranty.

Thank you to Corsair for providing us with an AX1200i PSU. The AX1200i was the first power supply to offer digital control and management via Corsair's Link system, but under the hood it commands a 1200W rating at 50C with 80 PLUS Platinum certification. This allows for a minimum 89-92% efficiency at 115V and 90-94% at 230V. The AX1200i is completely modular, running the larger 200mm design, with a dual ball bearing 140mm fan to assist high-performance use. The AX1200i is designed to be a workhorse, with up to 8 PCIe connectors for suitable four-way GPU setups. The AX1200i also comes with a Zero RPM mode for the fan, which due to the design allows the fan to be switched off when the power supply is under 30% load.

Thank you to G.Skill for providing us with memory. G.Skill has been a long-time supporter of AnandTech over the years, for testing beyond our CPU and motherboard memory reviews. We've reported on their high capacity and high-frequency kits, and every year at Computex G.Skill holds a world overclocking tournament with liquid nitrogen right on the show floor.

    Just to try and head the peanut gallery off at the pass. Based on something that either Ian or Ryan said a few days ago on twitter this should be the last board from the Z270 backlog. Reply

    take a look at the mainboard reviews here an anandtech and tell me anandtech is not biased.
    count the intel reviews then count the AMD reviews.

    full reviews for intel boards and "overviews" for AMD boards.

    and no, the reason is not that there are less AMD boards then intel boards.
    why not at least review the few AMD boards that exist?

    they rather preview Z270 boards then spending time on threadripper or AM4 boards.

    while AMD sells better in europe than intel for the past 3 month.

    We've got two AMD motherboard reviews being edited this week for next week. Our new motherboard review team, all of whom are in different corners of the world, is slowly coming up to speed. In case you didn't notice, E.Fyll has been doing our Z270 reviews this year and only Z270 - the other reviewers are taking on other chipsets - Joe for X299, Gavin for AM4. E.Fyll is likely to take TR4 now, and when Patrick gets back from his vacation, he's likely to take the Z370 content. Reply

    I'm looking forward to seeing more motherboard reviews :) I appreciate the quality content Reply

    Since Anandtech doesn't buy the gear they review, they can only review whatever the manufacturer sends them. If ASUS sends them 4 Intel boards and one AMD board, that's what they review. Reply

    "while AMD sells better in europe than intel for the past 3 month."

    Is that based on the data for one webtailer or the whole of Europe?
    For all CPUs or just a range?
    I doubt that AMD currently have the capacity to supply that much of the retail market but if that's what they have done it's amazing.

    yeah i will buy Z270 now that Z370 is released in 2 days.....

    great job on doing timely reviews. tremendous job.

    As per my tweet a few days ago, just getting the last ones out. The platform is still going to exist for a couple of years, with retail sales of both motherboards and processors. Reviews are still relevant. Reply

    Just wanted to chime in since you're being forced to defend yourself, that I appreciate all your reviews, whenever they're posted. I'm not in the market for new parts now, but I have in the past and will be again in the future. Your site has always been an invaluable resource, so thank you. Reply

    I bought this board based only on the spec sheet when the 7700k came out as there were no reviews at the time. It's nice to know that I got a good board even if the review is late, in particular I had no idea the onboard audio was that good, I figured it was all just marketing. Reply
