Socket LGA 775 ATX motherboard

The Intel BLKD975XBX2KR is an ATX form-factor motherboard built around the Intel 975X Express chipset and designed for LGA 775 processors. It accepts Core 2 Quad, Core 2 Extreme and Core 2 Duo CPUs with front-side bus speeds of 1066 or 800 MHz. The board ships without accessories.

Four DDR2 800 slots supporting 8 GB maximum

Memory capacity is defined by four 240-pin slots running DDR2 800 in dual-channel mode, with a total ceiling of 8 GB. This limit is the single specification that determines whether the platform can meet a given workload.

Suits legacy LGA 775 builds needing multi-GPU layout

The board suits enthusiasts maintaining or assembling a period-correct LGA 775 system that requires three PCI Express x16 slots and eight SATA 3 Gb/s ports. Builders who need more than 8 GB of memory or a newer memory standard should look at a different platform.

Questions about this item

What does the 8 GB DDR2 800 limit mean for a running system?

The board accepts up to 8 GB across its four 240-pin slots in dual-channel mode, so a fully populated kit will run at the rated 800 MT/s speed.

How do the three PCI Express x16 slots actually operate?

One slot runs at x16 or x8 electrically, a second at x8, and the third at x4, all sharing the 975X chipset lanes.

What power connectors and clearance does the ATX board need?

A 24-pin ATX power connector is required, and the board fits any standard ATX chassis with matching standoffs.
