Technical Specifications
Technical Summary
This Compal PGRAA motherboard, documented under board number LA-7191P revision 1.0 dated 2011-04-26, is built around the Intel Sandy Bridge processor platform paired with the Intel PCH Cougar Point - M chipset. Graphics processing is handled by a discrete NVIDIA N11E-GS GPU with a 192-bit memory interface supporting 1.5GB or 3GB of GDDR5 video memory. System memory consists of two 200-pin DDRIII SO-DIMM slots configured for dual-channel operation at 1066/1333 MT/s. The embedded controller is an ENE KB930 with a dedicated 128KB EC ROM. The system BIOS is stored on a 4MB SPI ROM. Audio is provided by a Realtek ALC269 HDA codec, and networking is handled by a Realtek RTL8111E 1G Ethernet controller. Additional I/O includes a JMicron JMB389C card reader and a Texas Instruments TUSB7320 USB 3.0 hub controller.
