Memory design featuring dual channels with two DIMMs per channel. Includes four DDR4 DIMM slots (288 pins each). Backed by PC4-17000 standard (DDR4-2133). Accepts up to 4 GB and 8 GB DDR4 modules. Compatible with 32-bit systems for up to 4 GB, and 64-bit systems for up to 64 GB unbuffered. The main concern here is likely the operating system version. Even though the board supports your RAM, a 32-bit OS may limit it to 4 GB. Running a 64-bit version would be ideal for optimal performance.
