The Intel Z690 Motherboard Overview (DDR5): Over 50+ New Models
by Gavin Bonshor on November 9, 2021 9:00 AM ESTASRock 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 E-ATX motherboard with two DDR5 memory slots and overclockers toolkit
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.
The ASRock Z690 Aqua rear panel (the Z690 Aqua OC drops two USB 3.2 G2 Type-A ports for a PS/2 port)
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.

Certainly, there are tradeoffs, keeping a socket; but, as Mr. Tuvok would say, "Ryzen, you are an unending source of astonishment." There was a time when sockets even took CPUs from different manufacturers. I remember my Socket 7 motherboard, though I never tried it, could take a K5 and some Cyrix CPUs as well. Those 5x something, something. How things have changed.A short-lived socket can be a pain in the behind too. I was one of those unlucky folk who ended up with Socket 754 and missed out on dual-channel DDR and a long upgrade path. In any case, that computer went kaput after four years.

Overclocking is for employees of motherboard companies.ECC RAM support should have been a standard feature from the beginning. Apple offered it on the Lisa in ‘83 and consumer computing has gone backward since.
Doublers, though... aren’t a bad thing as long as they’re implemented well — as I understand it. Better to have a good doubler implementation than a weak individual phase system. The main thing is to have a board meet the minimum spec for reliable (i.e. not overheating and/or failing) long-term support of its supported CPUs. Anything beyond that is unnecessary.

The problem with doublers is, they over-use it as a marketing technique to give the impression that a certain board has a large amount of phases.Oxford Guy - Saturday, November 13, 2021 - link
Weak phases with a mediocre/poor regulator aren’t necessarily better than ‘marketing phases’ via the use of doublers. That’s the case when the doublers are used a correctly.There are a lot of shenanigans, though — like not even utilizing the doubler fully but counting it as the doubling of phases. I also recall that one of the big tricks was putting extra chokes on the board to make it look like there are more phases.

Quite right, and one of the reasons why people have got to read a proper analysis of the VRM, or take a look at the lists on hardwareluxx for example.t.s - Tuesday, November 9, 2021 - link
Wish Intel go with their atv12vo. Or like business lines from HP, Dell, Lenovo, etc. 6 or 8 pin.shabby - Tuesday, November 9, 2021 - link
Mobo prices will go up even more, screw that.meacupla - Tuesday, November 9, 2021 - link
In the long term, I think the cost for ATX12VO will be cheaper.ATX12VO PSU will be cheaper than a comparable quality ATX PSU.
The BoM for 12V to 5V and 12V to 3.3V converters would go down, if mobo makers decide to stick to a single, standardized design.
With the way things are looking, electricity prices are unlikely to go down and continue to go up.

All ATX12VO is doing is shifting the cost from the PSU to the motherboard.Wrs - Wednesday, November 10, 2021 - link
If mobo makers can stick to one design why can't PSU makers? They already conform to ATX.ATX 12 VO increases costs for piecemeal upgraders because of the simple observation that PSUs outlive motherboards. The question would be whether the power savings are worth it. For prebuilts they're comparing power savings to 0 net component cost so 12VO is already the norm.
