For Intel's 15th generation Core Ultra 5 processor 245K, you'll need a motherboard with an LGA 1851 socket and a compatible 800-series chipset.

Motherboards for Intel processors are made with chipsets provided by Intel. Each chipset offers a unique set of capabilities. However, motherboards must explicitly support features and capabilities for you to use them. Verify that a motherboard supports the features and capabilities you desire.

The "K" in the model name 245K means it's an unlocked processor that supports overclocking. You will need a motherboard with overclocking support to overclock this CPU. Motherboards with the Z890 chipsets typically support CPU overclocking. If you don't want to use the overclocking functionality at this time, you can use a motherboard with Intel's other 800-series desktop chipsets (e.g., B860 or H810).

The W880 and Q870 chipsets are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

Other Considerations When Choosing a 245K Motherboard

Section Link

When choosing a motherboard for the 245K, we considered several key factors beyond socket type and chipset compatibility. These include form factor, expandability, power delivery, and features like USB ports, audio quality, and Wi-Fi support. By focusing on these elements, you can identify what matters most for your specific needs and ensure an optimal, future-proof setup.

Memory Overclocking

To overclock DDR memory via an XMP profile, your motherboard chipset must support memory overclocking. Find which chipsets support overclocking in our article, Which Chipsets Work With Intel's Core Ultra 5 processor 245K?.

Video Output Port

The absence of an "F" in the 245K model name indicates the CPU has integrated graphics support. Ensure your motherboard includes a video output port (e.g., HDMI) if you want to use integrated graphics.

Even if you primarily connect monitors to a dedicated graphics card, we found that integrated graphics can be beneficial when troubleshooting graphics card issues.

Storage: M.2 Slots and SATA Ports

NVMe M.2 cards are the latest and fastest SSD storage form. We recommend ensuring your motherboard includes enough slots for your needs.

The Z890, H870, and W880 chipsets support PCIe 5.0/4.0 hybrid configurations, with Z890 motherboards providing 24 PCIe 4.0 lanes + 20 PCIe 5.0 lanes for up to six x4 NVMe M.2 slots.

Learn more about storage types in our article Storage Type Comparison: M.2, U.2, NVMe, SATA, SSDs, HDDs.

Connectivity

USB

Ensure the motherboard provides enough USB ports at your desired speeds. The Z890 and W880 chipsets support the most USB ports for the 245K, including 5 USB 3.2 20 Gbps ports, 10 USB 3.2 10 Gbps ports, and 10 USB 2.0 5 Gbps ports, plus native Thunderbolt 4/USB4 connectivity.

High-bandwidth devices typically fall into two categories: storage devices and high-resolution video equipment. These devices depend on high-speed data transfer for optimal performance. In our testing, we've encountered instances where insufficient bandwidth significantly impeded performance, particularly when working with large data transfers and high-resolution video editing.

Audio

When choosing a motherboard, prioritize one with physical audio ports if sound quality matters to you. Look for color-coded 3.5mm jacks (green for front speakers, black for rear, orange for center/subwoofer) to ensure proper connections for surround sound systems.

If you're using a soundbar or AV receiver, we recommend selecting a motherboard with an optical (S/PDIF) port. It provides cleaner audio by avoiding electrical noise, which makes a noticeable difference in sound quality.

While built-in audio quality isn't the most critical factor, choose a motherboard with a high-quality audio codec if you're using high-end headphones. It can reduce background noise, especially at higher volumes. If the motherboard's audio doesn't meet your standards, consider an external audio solution like a USB DAC as a reliable backup. It's an affordable way to bypass onboard limitations and improve sound quality for both desktops and laptops.

Choose a motherboard whose ports are compatible with your current equipment to avoid costly upgrades in the future.

Form Factor

When it comes to motherboards, we've encountered three primary form factors. In our experience, ATX stands out as the most common for desktop PCs. We've also explored Mini-ITX and MicroATX for building mini-PCs, and found they typically offer fewer PCIe slots, RAM slots, and storage support.

We've observed that these smaller form factors are backward compatible with standard ATX cases, using a subset of their mounting holes. In fact, we've frequently used Mini-ITX motherboards in ATX cases.

One crucial consideration is ensuring your case matches your motherboard's form factor. We've learned from experience how important it is to choose a case that aligns with your motherboard's specific needs.

PCIe Expansion Slots

The Z890, W880, and Q870 chipsets provide the most flexibility when paired with the 245K, supporting dual PCIe 5.0 x16 slots (x8/x8 bifurcation) and three PCIe 4.0 x4 slots for multi-GPU and expansion card configurations.
