PC Build to Run GLM-4.7-Flash 30B-A3B Locally (Q8_0)

Written by Jakub Rusinowski · Last updated August 15, 2026

A complete parts list — GPU, motherboard, RAM and PSU — worked backward from GLM-4.7-Flash 30B-A3B's VRAM requirement at Q8_0. Prices are 2026 street estimates and vary.

Requirements

GPU: 2× AMD Radeon RX 7900 XT

2× AMD Radeon RX 7900 XT (40 GB pooled) covers GLM-4.7-Flash 30B-A3B at Q8_0 (~33 GB needed), with headroom.

Motherboard: ASUS ProArt X670E-Creator WIFI

X670E (AM5) — pairs with the AMD Ryzen 9 7900X; DDR5, dual PCIe 5.0 x16 (x8/x8) for multi-GPU, 4 DIMM slots to 192 GB.

RAM: Corsair Vengeance 32GB (2x16GB) DDR5-6000 C30 (AMD EXPO)

32 GB DDR5-6000 (2x16GB) meets GLM-4.7-Flash 30B-A3B's 32 GB recommended system RAM.

PSU: Corsair HX1500i (ATX 3.1)

1500 W 80+ Platinum covers 2× AMD Radeon RX 7900 XT (630 W) + CPU 170 W with 30% headroom (~1040 W required).

Swap Alternatives

• GPU: NVIDIA RTX 6000 Ada Generation — Single-GPU alternative (no tensor split, simpler): NVIDIA RTX 6000 Ada Generation 48 GB at $6,799.
• RAM: Corsair Vengeance 64GB (2x32GB) DDR5-6000 C30 (AMD EXPO) — More headroom: 64 GB DDR5-6000.

• GLM-4.7-Flash 30B-A3B at Q8_0 needs more VRAM than any single consumer GPU, so this uses 2× AMD Radeon RX 7900 XT (40 GB pooled via tensor split) — cheaper than the single NVIDIA RTX 6000 Ada Generation (48 GB, $6,799) that would also fit.
