LGA 1155 Intel B75 Motherboard

The GIGABYTE GA-B75-D3V is an ATX motherboard built around the Intel B75 chipset for LGA 1155 processors. It accepts Intel Core i7, i5, i3, Pentium and Celeron CPUs, making it suited for budget desktop builds or legacy system repairs. Four DDR3 DIMM slots support up to 32GB of system memory.

PCI Express 3.0 x16 and SATA Layout

A single PCI Express 3.0 x16 slot provides the primary expansion path for a discrete graphics card. Storage connectivity comes from four SATA II ports and one SATA III port, allowing a mix of hard drives and a faster SSD. Two USB 3.0 ports sit on the rear I/O panel, with headers for two additional front-panel USB 3.0 connections.

Realtek ALC887 Audio and Gigabit LAN

Onboard audio uses the Realtek ALC887 codec with support for up to 7.1 channel output through the front-panel header. Networking is handled by an Atheros Gigabit Ethernet controller rated at 10/100/1000 Mbit. The board measures 30.5 by 21.5 cm and ships with a metal battery and one SATA cable.

Questions about this item

How much DDR3 memory can the GA-B75-D3V take before the 32 GB limit is reached?

The board has four DDR3 DIMM slots and supports a maximum of 32 GB total, so filling all four slots with 8 GB modules reaches the limit.

What noise or heat should I expect from the onboard Atheros GbE LAN and Realtek ALC887 audio when the system runs all day?

Both controllers are passive silicon with no fans; they add negligible noise and only modest heat that the case airflow normally handles.

Which CPU cooler mounting holes does the LGA 1155 socket use so I know my existing cooler will fit?

The LGA 1155 socket uses the standard 75 mm square mounting pattern common to Intel desktop sockets of that era.
