Platform Match

The Intel Core Ultra 5 245K requires the LGA1851 socket, paired with Z890 or B860 chipsets. This platform transitions exclusively to DDR5 memory and PCIe 5.0 connectivity.

VRM Guidance

A 125W TDP CPU like the 245K needs at least a 10-phase VRM. Mini-ITX boards require robust heatsinks and active cooling to prevent thermal throttling in compact cases.

Upgrade Path

LGA1851 offers PCIe 5.0 for GPUs and M.2 SSDs. Mini-ITX limits expansion to one PCIe slot and typically two M.2 slots, making high-capacity drives crucial.

Frequently Asked Questions

Can I use my old DDR4 RAM with the Core Ultra 5 245K?

No, the LGA1851 platform and Z890/B860 chipsets exclusively support DDR5 memory. You will need to upgrade your RAM.

Do LGA1700 CPU coolers fit the new LGA1851 socket?

Yes, LGA1851 shares the same mounting hole spacing and Z-height as LGA1700, so most LGA1700 coolers are compatible.

Is a Z890 board required for the Core Ultra 5 245K?

No, but Z890 is recommended for CPU overclocking. A B860 board works perfectly if you run the 245K at stock settings.
