Intel BLKD975XBX2KR ATX Motherboard 975X Express LGA 775 DDR2 800 8GB

Intel 975X Express ATX Board

The Intel BLKD975XBX2KR is an ATX motherboard built around the Intel 975X Express northbridge and ICH7R southbridge. It fits LGA 775 processors including Core 2 Quad, Core 2 Extreme and Core 2 Duo with front-side bus speeds of 1066 or 800 MHz. The board provides four 240-pin DDR2 800 slots supporting up to 8 GB in dual-channel mode.

Three PCI Express x16 Slots

Three physical PCI Express x16 slots are available; one runs at electrical x16 or x8, a second at electrical x8 and the third at electrical x4. This layout replaces earlier single-slot designs and the jump is worth it when a build needs multiple graphics cards or additional expansion cards that require x16 mechanical slots. Two conventional PCI slots remain for legacy add-in cards.

Suited for Multi-GPU LGA 775 Builds

The board suits enthusiasts assembling a Core 2 Quad or Core 2 Extreme system that can use several graphics cards or a mix of x16 and x8 add-in cards. Builders who need integrated Wi-Fi, modern high-speed storage interfaces or a newer CPU socket should look at something else.
