The is a versatile micro-ATX motherboard commonly found in pre-built desktop systems like the Acer Predator G3620 , Gateway DX4870 , and Acer Aspire M1935. Built on the Intel B75 Express chipset , it provides a stable platform for 2nd and 3rd Generation Intel Core processors. Core Specifications Socket: Intel LGA 1155 (Socket H2). Chipset: Intel B75 Express (BD82B75 PCH). Form Factor: Micro-ATX (mATX).
Connect the positive lead to Pin 1 and the negative/ground lead to Pin 3 . Note: If your case uses a split 3-pin connector with a blank middle slot, you may need to reposition the wires into adjacent pins to fit this 2-pin block.
Note: AMD Ryzen processors or newer Intel LGA 1150/1151 CPUs are physically incompatible and will not fit this socket. Memory Configurations The 4 DDR3 DIMM slots support dual-channel configurations. DDR3 1333 MHz and 1600 MHz unbuffered modules. acer ipimbar rev 102a manual top
