Technical Summary

This Quanta Helios (ZGRC/ZGRE) motherboard is built on the Raptor Lake-HX platform with a BGA1744 CPU socket. Memory architecture consists of two DDR5 SODIMM slots supporting up to 32GB each at 4800MHz across Channel A and Channel B. The discrete GPU options include NVIDIA GN20-E3, GN20-E5/E6/E7, GN20-P1, and GN21/WN21-MB1 GB5B-256VRAM with gDDR6 memory, managed by a PI3DPX8121ZLDEX eDP mux and a 16M VBIOS. The embedded controller is an IT5570, and the audio codec is an ALC3324. Connectivity is handled by an Intel Maple-Ridge JHL8540-QUBZ Thunderbolt controller, a CCG6 CYPD6227-48LQXI PD controller, PS8811QFN36GTR2-A3 USB re-drivers, and an E3100G LAN IC. The system includes a 16M SPI BIOS flash and an ene6K5130 LED driver.
