Technical Specifications
Technical Summary
The Lenovo M920z/M828z motherboard, board number A3199 revision 1.0, is built on the CFL-S 6+2 Processor 65W Intel platform with an LGA1151 socket. The PCH is a Q370 for M920z and B360 for M828z. Graphics are handled by an AMD GPU GB2b-64 R17M-M1-70 with GDDR5 memory configured as 8Gb (256MX32) at 1500MHz per channel. The system uses DDR4 2400/2666 memory in SO-DIMM slots for channels A and B. The embedded controller and SIO are combined in an IT8738E. Audio is provided by an ALC233-VB2-CG codec. BIOS storage uses SPI Flash ROM with capacities of 16M+8M for M920z and 16+4M for M828z. Networking includes a JACKSONVILLE LAN IC and an M.2 Slot E Key for WLAN. A RTS5170-GR card reader, TS3DV642 USB hub, and PS8330B HDMI level shifter are present. The scalar is an RTD2526-CG, and an eSPI TPM module is supported.
