Target platform

The ASRock Rack Z690D4U-2L2T/G5 is a Micro-ATX server motherboard built for single-socket LGA 1700 processors. It supports Intel Core, Pentium and Celeron series CPUs from the 12th, 13th and 14th generations. The board is aimed at builders who need dual 10GbE networking and flexible storage expansion in a compact form factor.

Memory specification

Four DDR5 288-pin DIMM slots accept non-ECC UDIMM modules up to 32GB each. Speeds scale with population: 5600MT/s with one DIMM per channel, 4000MT/s with two single-rank DIMMs per channel and 3600MT/s with two dual-rank DIMMs per channel. ECC memory is not supported.

Expansion and connectivity

One PCIe 5.0 x16 slot, one PCIe 4.0 x4 slot and one PCIe 3.0 x1 slot provide add-in card options. Three OCuLink connectors deliver PCIe 4.0 x4 links and a fourth OCuLink can alternatively provide four SATA 6Gb/s ports. A single M.2 M-key slot supports 2230, 2242, 2260 and 2280 drives on a PCIe 3.0 x4 interface. Dual 10GbE and dual 1GbE RJ45 ports are driven by Intel X710 and i210 controllers respectively, while an Aspeed AST2600 chip handles onboard video.

Highlights

  • Supports 12th, 13th and 14th Gen Intel Core, Pentium and Celeron processors
  • Dual 10 GbE Intel X710 LAN ports for high-speed networking
  • Four DDR5 UDIMM slots up to 32 GB per DIMM
  • PCIe 5.0 x16 slot plus PCIe 4.0 x4 and PCIe 3.0 x1 expansion

Questions about this item

Will the 5600 MT/s DDR5 speed hold with all four slots populated?

With two DIMMs per channel the board runs DDR5 at 3600 MT/s for dual-rank modules and 4000 MT/s for single-rank modules.

What happens to the second OCuLink port when a card is installed in the PCIe 4.0 x4 slot?

The OCuLink4 connector shares lanes with that slot and is automatically disabled when the slot is populated.

Does the Micro-ATX 9.6-inch square layout fit a standard rack-mount chassis?

The board measures 9.6 by 9.6 inches and uses the Micro-ATX mounting pattern, which matches common 1U and 2U server cases.
