toshiba qosmio x755 la-7191p pgraa rev 1.0
Technical Specifications
Technical Summary
This Compal PGRAA (LA-7191P) motherboard schematic, revision 1.0 dated 2011-04-26, details an Intel Sandy Bridge processor platform paired with an Intel PCH Cougar Point - M southbridge. The discrete graphics solution is an NVIDIA N11E-GS with a 192-bit memory interface supporting 1.5GB or 3GB of GDDR5 VRAM. 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 main BIOS is stored on a 4MB SPI ROM. Audio is handled by a Realtek ALC269 HDA codec, and networking is provided by a Realtek RTL8111E 1G Ethernet controller. Additional I/O includes a JMicron JMB389C card reader and a TI TUSB7320 USB 3.0 hub controller.
