Modded Nvidia RTX 5090 with 96 GB VRAM and custom BIOS surfaces in China - Notebookcheck
A modified Nvidia GeForce RTX 5090 with 96GB of VRAM has appeared on a Chinese secondhand marketplace, offering custom PCB schematics and modified BIOS firmware exclusively to businesses.
The modification triples the RTX 5090's standard VRAM capacity, bringing it to the same level as Nvidia's much more expensive RTX Pro 6000 Blackwell. This development comes as Nvidia faces what has been described as a crisis in the market.
Hardware repair specialist VIK-on discovered the listing on Xianyu, Alibaba's secondhand marketplace. The seller, based in Changsha, China, is offering complete modification packages that include custom PCB schematics and modified BIOS firmware.
Business-Only Offering
The listing shows a placeholder price of 6,488,888 yuan, with actual pricing to be negotiated privately. The seller explicitly states that the offering is intended exclusively for business customers, who must identify their companies and agree to confidentiality requirements.
Individual customers are explicitly discouraged from making inquiries.
Technical Details
Images accompanying the listing show a heavily modified graphics card populated with Samsung memory modules. The alleged design uses a clamshell memory configuration, placing memory chips on both sides of the PCB to achieve the advertised 96GB capacity.
This isn't the first appearance of a 96GB RTX 5090 online, as a similar listing surfaced on Alibaba in September, though its contradictory memory specifications raised questions about authenticity. Chinese workshops have previously been known to dismantle retail RTX 5090 cards and transplant their GPUs onto custom boards for AI servers.
