A r/LocalLLaMA user with 104 upvotes and 60 comments is documenting their investigation into Chinese-modified RTX 4090 cards with 48GB VRAM, noting a near-total absence of English-language information. The cards reportedly exist and are being sold, but performance characteristics, reliability data, and modification techniques remain largely undocumented outside Chinese forums. The thread is becoming a crowdsourced knowledge base for the local inference community.
