Chinese modders unlocked infinite storage glitches through repurposed AMD motherboard chips on expansion cards. Overseas vendors started selling custom hardware featuring X870, X670, and B650 silicon that plugs straight into PCIe slots. These gadgets allow basic computers to handle massive input capabilities normally restricted to expensive mainboards. A creator on Bilibili highlighted the Oshwhub project, which utilizes Promontory 21 tech to function as a standard device regardless of the platform.

Many units likely escaped from AMD testing labs into the wild. The B650 version hides beneath a small heatsink and uses a PCIe 4.0 x4 interface to drive four M.2 sockets alongside four SATA III ports. That specific card sells for roughly 300 RMB or forty bucks. Older X570 variants cost about thirty dollars while offering similar storage options alongside extra USB Type-A and Type-C ports.

One weird feature allows linking these boards in a series since some feature a spare PCIe slot. Connecting them sequentially creates endless expansion theoretically, though it sounds impractical for daily use. Speed benchmarks indicate these add-ons perform exactly like native onboard controllers regarding transfer rates. Users must flash fresh firmware to get them running, but sellers apparently share the files through social chats.
