The MILK-V Titan is a mini-ITX RISC-V motherboard that can be used in high-performance desktop applications as well as edge computing, and lightweight server applications, but can still use standard PC components and enclosures. It is driven by a 2 GHz UltraRISC UR-DP1000 octa-core processor (RG64GCBH) with eight-core design in four clusters of dual-cores. Every cluster will have 4 MB of L3 cache which will give us 16 MB. The CPU is entirely compatible with the RVA22 profile, with omission of the V (vector) extension, and also the RVA23 requirement.
The MILK-V Titan is constructed in a typical mini-ITX size of 170 x 170 mm (6.7 x 6.7 inches) and can fit most PC cases, as well as accommodates most desktop hardware. The board has a maximum DDR4 ECC memory of 64GB in dual channel and supports up to 3200 MT/s. Expansion and connectivity are provided as USB-A and USB-C, Gigabit Ethernet, BMC, M.2 NVMe(PCIe Gen4 x4) with PCIe Gen4 x16, and a discrete graphics card, AI accelerator or high-speed network adapters slot.
Other features are a PWM fan connector, an RTC socket with a CR1220 battery, and flexible power sources, where a DC5525 connector is provided with light load applications, or an ATX standard power connection with high load. Generally, the MILK-V Titan is a complete hardware and software solution to implementing the RISC-V architecture into the mainstream mini-ITX.
Milk-V Titan specifications:
The UltraRISC UR-DP1000 SoC and the MILK-V Titan have eight RISC-V UR-CP100 (RV64GCBHX) cores at 2.0 GHz that provide power to this platform. Each of the cores has its own 64 KB of instruction and 64 KB of data L1 cache, and 512 KB of L2 cache. The processor is dual-cluster-based, whereby it has two four-core clusters, each having 4 MB of L3-cache, amounting to 16 MB. It also supports up to 16 MB of system-level shared cache (SLC) in order to enhance coordination between multi-core. The CPU is both RVA22-compliant and RVA23-excluding-V-compliant and also hardware-virtually-compatible with support of hardware virtualization via the RISC-V RV64 ISA H (v1.0) extension.
For memory and storage, the board supports up to 64 GB of DDR4 memory at 3200 MT/s via dual DIMM slots with ECC support. Storage is handled through an M.2 Key-M socket with PCIe Gen4 ×4 support for NVMe SSDs. Networking includes a Gigabit Ethernet RJ45 port, while USB connectivity consists of four USB 3.0 Type-A ports (5 Gbps), one USB 2.0 port via a front-panel header, and a USB Type-C debug port. Expansion options include a full-length PCIe 4.0 ×16 slot with Gen4 ×16 signaling for graphics cards or compute accelerators.
The MILK-V Titan also integrates a dedicated BMC with a 100 Mbps RJ45 management port, a USB 2.0 Type-A port for BMC storage, and a USB Type-C port. Debugging interfaces include a 3-pin UART header and a USB Type-C debug connector. Additional hardware features include power, reset, BMC reset, and BMC boot buttons, a front-panel header for power and reset buttons and status LEDs, a PWM fan connector, and an RTC socket for a CR1220 battery. Power can be supplied via a 12 V DC 5.5/2.5 mm barrel jack or a standard 24-pin ATX connector. Power consumption is around 14 W at idle and approximately 30 W under full load (with 64 GB DDR4 and a 128 GB SSD). The board follows the mini-ITX form factor at 170 × 170 mm and is compliant with FCC and CE standards.
Although the software documentation is still under development, the company states that the platform supports Fedora, Debian, and Ubuntu, with Ubuntu listed as the preferred operating system. UEFI support with ACPI, CPPC, and SMBIOS is expected to allow compatibility with additional RISC-V operating system images.
The Titan mini-ITX motherboard can now be pre-ordered on Arace Tech for $329 but Arace is offering $50 off when the users pre-order with the coupon ARACE-TITAN, bringing the price down to $279. Additional information can be found on the product page and documentation page as well.
