Lenovo ThinkCentre M90z IQ370SV Schematic
Technical Specifications
Technical Summary
The Lenovo M920z/M828z motherboard, project code IQ370SVP, board number A3199 revision 1.0, is built on the Intel CFL-S 6+2 Processor 65W platform with an LGA1151 socket. The PCH is Q370 for M920z and B360 for M828z. Graphics are handled by an AMD R17M-M1-70 GPU with GB2b-64 architecture, supported by GDDR5 memory. The system uses DDR4 2400/2666 SO-DIMMs across two channels. The EC/KBC is an IT8738E, and the audio codec is an ALC233-VB2-CG. BIOS storage uses SPI Flash ROM with configurations of 16M+8M for M920z and 16+4M for M828z. Networking includes an Intel JACKSONVILLE LAN IC and an M.2 Socket E KEY CNVi WLAN slot. The scalar is an RTD2526-CG, and the HDMI level shifter is a PS8330B. The charging IC is an RTS5170-GR, and the USB hub IC is a TS3DV642.
