Compact AM5 motherboards are becoming more important as Ryzen 9000 systems continue getting higher power targets into smaller gaming builds. Colorful’s new iGame B850M ULTRA-OC V14 and ULTRA-S V14 boards focus on that segment, combining PCIe 5.0 storage, WiFi 7, and upgraded VRM designs inside a Micro-ATX layout for Ryzen 7000, 8000, and 9000 processors.
Both models use the same dark ULTRA-series styling along with large Frost Armor heatsinks covering most of the PCB surface. Colorful says the cooling layout uses a full-coverage design intended to improve heat dissipation around the VRM and storage sections.
The ULTRA-S V14 sits at the higher end of the pair with a 14+2+1 phase layout using 80A DrMOS stages, while the ULTRA-OC V14 uses a 10+2+1 design rated at 60A. Despite the smaller footprint, both boards still include a full PCIe 5.0 x16 slot for newer graphics cards.
Colorful also takes a different approach to memory support on each board. The ULTRA-S V14 carries four DDR5 slots with support for up to 256GB memory, while the ULTRA-OC V14 uses a two-DIMM configuration supporting up to 128GB. Both boards support DDR5-8400 overclocking together with AMD EXPO and Intel XMP memory profiles.
The two boards also separate themselves through storage layout. The ULTRA-OC V14 includes four M.2 slots, including two PCIe 5.0 x4 connections and two PCIe 4.0 x4 slots. The ULTRA-S V14 instead uses a three-slot setup with two PCIe 5.0 x4 connections, one PCIe 4.0 slot, and four SATA ports. RAID support also differs slightly, with the ULTRA-S model supporting RAID 0, 1, and 10, while the ULTRA-OC version supports RAID 0 and RAID 1.
The networking setup also changes between models. The ULTRA-OC V14 uses Realtek 5GbE LAN together with WiFi 7 and Bluetooth 5.4, while the ULTRA-S V14 switches to 2.5GbE networking while keeping the same wireless support.
Audio hardware differs between the two boards as well. HDMI 2.0, DisplayPort 1.2, BIOS flashback controls, CMOS clear buttons, and USB-C connectivity are included across the lineup. The ULTRA-S V14 adds a faster 20Gbps USB 3.2 Gen 2×2 Type-C connection, while the ULTRA-OC V14 uses a 10Gbps Type-C port instead. The ULTRA-S model also adds a secondary PCIe 4.0 x1 expansion slot together with SPDIF audio output.
The higher-end ULTRA-S V14 gets a stronger onboard audio setup. The ULTRA-S V14 uses the higher-end Realtek ALC1220 codec, while the ULTRA-OC V14 ships with the more entry-level ALC897 solution. Both support 7.1-channel audio.
Colorful says both boards went through more than 200 validation tests and include multiple protection features aimed at long-term stability. RGB lighting synchronization is handled through the company’s iGame Center software.
Many newer AM5 motherboards have moved toward larger ATX and E-ATX designs, especially in the higher-end segment. These two boards take a different approach by keeping PCIe 5.0 storage, DDR5-8400 support, and newer networking features inside a smaller Micro-ATX layout. For builders trying to fit Ryzen 9000 hardware into more compact gaming systems, that combination may end up being the bigger selling point than raw specifications alone.
