Let’s break down what makes Socket 1151 motherboards a solid pick—and whether it fits your computing needs.
What Is a Socket 1151 Motherboard?
A Socket 1151 motherboard, also known as LGA 1151, is an Intel CPU socket first introduced in 2015. The “1151” number refers to the number of pins (1151 contacts) on the socket that connect the processor to the motherboard.
Key Characteristics:
- Designed for Intel 6th to 9th Gen CPUs
- Compatible with Core i3, i5, i7, i9, Pentium, and Celeron processors
- Supports DDR4 RAM and PCIe 3.0/4.0 (depending on chipset)
- Offers various form factors: ATX, microATX, and mini-ITX
CPU Compatibility: Which Processors Work with Socket 1151?
This is where things get slightly tricky Socket 1151 has two generations with different pin layouts, meaning not all 1151 CPUs and motherboards are cross-compatible.
1151 (1st Gen) — for Intel 6th & 7th Gen
- Supported CPUs:
- Intel Core i7-7700K, i5-7600, i3-6100, Pentium G4560
- Compatible Chipsets:
- H110, B150, H170, Z170, B250, H270, Z270
1151 (2nd Gen) — for Intel 8th & 9th Gen
- Supported CPUs:
- Intel Core i9-9900K, i7-9700K, i5-9400F, i3-8100
- Compatible Chipsets:
- H310, B360, H370, Z370, Z390
Important Note: You can’t use an 8th/9th Gen CPU in a 6th/7th Gen motherboard even though the socket is the same, the electrical compatibility and BIOS support differ.
Why Choose a Socket 1151 Motherboard in 2025?
Even though newer socket types are available, Socket 1151 remains relevant for several reasons:
Budget-Friendly Builds
- Great for affordable gaming PCs or workstations
