ASRock Z690 Aqua and Aqua OC (DDR5)

In 2019, ASRock debuted its highly premium yet expensive Aqua series through the ASRock X570 Aqua, which we reviewed. We also reviewed the ASRock Z490 Aqua, and our overall thoughts were that the Aqua was extremely 'cool' in both performance and aesthetics. ASRock at CES 2022 pulled the trigger and launched not one, but two new Aqua series motherboards for Intel's Alder Lake. One features a conventional desktop design, while one is designed for extreme overclockers looking to maximize both compute and memory performance under sub-zero cooling.

The ASRock Z690 Aqua E-ATX motherboard

The ASRock Z690 Aqua has a 'wave' of features, including a large custom monoblock designed to cool both the processor and large advertised 19+1 phase power delivery using the latest premium 105 A power stages. It also includes stainless steel plating across the 12-layer E-ATX sized PCB, with plenty of integrated RGB lighting for users to host their own epic water-cooled discotheque. The ASRock Z690 Aqua also includes an OLED display, which can display many different forms of information from voltages, frequency and can be configured within the BIOS.

Dominating the lower portion of the board are two full-length PCIe 5.0 slots that can operate at x16 or x8/x8, one full-length PCIe 4.0 x4, and one PCIe 3.0 x1 slot, with three PCIe 4.0 x4 M.2 slots that all include M.2 heatsink coverage. For SATA, there are eight ports in total, with four coming from the chipset with support for RAID 0, 1, 5, and 10 arrays, while an ASMedia ASM1061 SATA controller powers the other four. As does most premium Z690 motherboards, the Z690 Aqua can support up to DDR5-6400 memory, with a combined capacity of 128 GB across four slots.

The ASRock Z690 Aqua OC shares the same core feature set but has two memory slots with support for DDR5 memory. As many 'OC' branded boards do, this is to enhance memory performance when overclocking. ASRock also states that it includes an external clock generator to boost OC potential, as well as the exact premium 19+1 phase power delivery as the 'regular' Z690 Aqua. It also includes an overclocker's toolkit next to the memory slots for on-the-fly overclocking. However, both models have a power and reset button, with a two-digit LED debugger.

On the rear panel, the ASRock Z690 Aqua includes two Thunderbolt 4 Type-C with two DisplayPort 1.4 video inputs, two USB 3.2 G2 Type-A, and four USB 3.2 G1 Type-A ports. The ASRock Z690 Aqua OC has the same layout, except it drops two USB 3.2 G1 Type-A ports for a PS/2 keyboard and mouse combo port. Both models feature a Marvel Aquantial AQC113CS 10 GbE and Killer E3100 2.5 GbE controller pairing, as well as a Killer AX1675 Wi-Fi 6E CNVi. For users planning to use integrated graphics, there's a single HDMI 2.1 video output, as well as five 3.5 mm audio jacks and S/PDIF optical output powered by a Realtek ALC1220 HD audio codec and ESS Sabre 9128 DAC. Finishing off the rear panel is a clear CMOS and BIOS Flashback button pairing.

    Will there be a list of DDR4 only board as well?
  • Ryan Smith - Wednesday, November 10, 2021 - link

    Yes, we're also putting together a guide for DDR4 boards.
  • jh20001 - Wednesday, December 1, 2021 - link

    Any news on the DDR4 story? Would be nice to know what model is the best for performance/features in the eyes of others.
  • Flunk - Tuesday, November 9, 2021 - link

    Intel's actually released a compelling new chipset? I'm surprised to see DDR5 and PCIe 5 support, but USB 4 seems to be notably absent, despite there being no reason at all to omit it. Intel is finally one-upping AMD after a few years of playing #2.

    Thunderbolt4 is usb4 capable…
  • CharonPDX - Tuesday, November 9, 2021 - link

    Yep, the only thing USB4 adds over "USB 3.2 2x2" is Thunderbolt support. Therefore any Thunderbolt 4 device is automatically USB4. In fact, essentially any board with "Thunderbolt 3" along with USB 3.2 2x2 basically get "USB4" status for free.
  • DigitalFreak - Tuesday, November 9, 2021 - link

    USB 3.2 2x2 is 20 Gbps. USB 4 is 40 Gbps.
  • 12345 - Wednesday, November 10, 2021 - link

    That's why they mentioned TB3. 40Gbps support is also optional for USB4.
  • 12345 - Wednesday, November 10, 2021 - link

    DP 2.0 is mandatory for USB4 so TB3 support isn't good enough.
  • KarlKastor - Wednesday, November 10, 2021 - link

    That is only the name. The question is, with what speed you can run USB devices.
