Firmware And Testing Configuration
ASRock’s X370 UEFI options are consistent from product to product, and the main difference between the Taichi and the X370 Gaming K4 is the synchronization of the box art with the UEFI. However, this time around we'll provide a little more depth to the options. For starters, CPU frequencies are listed in the table or are accessible via the “+/-” keys in 50MHz increments.
If overclocking memory is your thing, DDR4-2933 and DDR4-3200 are the only other stock options for easy tweaking. Of course, BCLK overclocking might open doors to other frequencies, but that comes with the risk of harmful system side effects. Voltage biasing for the core is accessible by holding down the plus key or keying in the desirable voltage. Note that voltages are adjustable in increments of 6.25mV. For the DIMMs, voltage set points are adjustable by 5mV increments.
We'll stand by our “too many options” statement from the previous ASRock review. Sure, professional overclockers might find using the "disabling platform first error handling" or "freezing DF module queues on error" helpful, but do they really need "location of private memory regions," "disabling individual I2C interfaces," and "clear MCA at warm RST?" Give me a break. When the description lists specific address definitions or “no help string,” it doesn't need to be available to the normal user.
More recent versions of the UEFI let you disable SMT. In our overclocking quest, we used this to help debug stability issues, but we encountered a scenario in which the option would not reset itself without intentionally causing the UEFI to reset. This would only occur when booting with an incompatible memory configuration, which was frustrating.
Another addition in newer firmware versions is the ability to flash through the OS, which we found helpful while making a mess of things when overclocking.
We haven't changed much. We did get our hands on some better memory—HyperX Predator DDR4-3200MHz—but we won't spoil the fun of our overclocking section. The Nocuta NH-D15 SE-AM4 returns as well. Special thanks to Noctua for supplying this and two more coolers to be investigated soon.
The biggest addition to the test suite are three 1080p monitors in portrait mode. Turning on Nvidia’s Surround mode while implementing bezel correction gets us a system resolution of 3460x1920. Not exactly 4K but darn close, and at least satisfies some of the concerns expressed about representing higher end gaming. Even if y’all don’t like it, it’s still pretty damn sweet.

We did collect some SLI data using a second GTX 970 GPU we have on hand, but unfortunately three of the four games we tested do not use SLI while in this multi-monitor configuration. If there are more games you want us to run, let us know in the comment section. How about some RAID tests or network performance?
