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 and Cougar Point PCH platform. The system firmware is stored on a 4MB SPI ROM. Embedded controller functions are handled by an ENE KB930 EC, which has a dedicated 128KB EC ROM. Audio is managed by a Realtek ALC269 HDA codec. Networking is provided by a Realtek RTL8111E 1G Ethernet controller. The discrete graphics solution uses an NVIDIA N11E-GS GPU with a 192-bit memory interface and GDDR5 memory. Memory configuration consists of two 200-pin DDRIII SO-DIMM slots supporting dual-channel architecture. Additional I/O controllers include a JMicron JMB389 card reader and a TI TUSB7320 USB 3.0 hub controller.
Technician FAQ
Q: What is the BIOS flash configuration on this motherboard?
A: The motherboard uses a single 4MB SPI ROM for BIOS storage.
Q: What EC/KBC is used and is it programmable?
A: The embedded controller is an ENE KB930. The schematic indicates a dedicated 128KB EC ROM, suggesting the EC firmware is stored externally.
Q: What is the discrete GPU configuration?
A: The motherboard uses an NVIDIA N11E-GS GPU with a 192-bit memory interface, supporting 1.5GB or 3GB of GDDR5 memory.
Q: What memory type and configuration does this board support?
A: It supports DDRIII memory in a dual-channel architecture, using two 200-pin SO-DIMM slots running at 1066/1333 MT/s.
Q: What are the key I/O controllers on this board?
A: The board features a Realtek RTL8111E 1G LAN, a JMicron JMB389 card reader, and a TI TUSB7320 USB 3.0 hub controller.
