Socket 1155 Micro ATX Board
The MSI B75MA-E33 is an Intel B75 motherboard for LGA 1155 processors. It fits third-generation Core i7, i5, i3, Pentium and Celeron CPUs. The Micro ATX form factor measures 23.6 by 20.0 cm and supports up to 16 GB of dual-channel DDR3 memory.
Expansion And Connectivity
One PCIe 3.0 x16 slot, one PCIe 2.0 x1 slot and one PCI slot provide add-in card options. Storage uses three SATA II ports and one SATA III port. Networking is handled by a Realtek 8111E Gigabit LAN controller. Rear I/O supplies four USB 2.0 ports and 8-channel audio via the Realtek ALC887 codec.
Memory Speed Ceiling
The highest validated DDR3 speed is 2400 MHz when overclocked, with standard support down to 1066 MHz. This ceiling decides whether the board can meet a given memory-performance target. Buyers needing faster memory standards must choose a different platform.

Questions sur cet article
Will the CMOS battery or the Realtek ALC887 audio codec need replacing during the board's life?
The package includes a metal CMOS battery for the real-time clock; the Realtek ALC887 audio codec is soldered on and not user-replaceable.
Which limit appears first when the single PCIe 3.0 x16 slot runs at full load for hours?
The lone PCIe 3.0 x16 slot carries all expansion bandwidth, so graphics or compute cards hit that ceiling before memory or SATA.
How hot or loud does the board get when the 16 GB DDR3 limit and Realtek 8111E LAN are active all day?
Passive chipset cooling and no onboard fan keep noise near zero; sustained loads warm the B75 chipset and VRM area but stay within normal operating temperatures.
