In September this year, there had already been one listed by Shenzhen Shuoqiao Intelligent Technology. RTX 5090 96GB memory modded versionpriced at $3,888, but the product photos did not show the interior, and the memory was even listed as GDDR6X, which completely fails to match the GDDR7 used by the RTX 5090, making it hard to believe it is real. Two months later, a new RTX 5090 96GB has recently appeared on a Chinese auction platform. Unlike last time, the seller also included photos of what appears to be the actual PCB, with the GPU model and memory chip numbers clearly visible. Even more unusual, it only accepts orders from enterprise customers, and they must first sign a nondisclosure agreement.

The RTX 5090 96GB modded card has appeared again! This time there are even PCB photos, but it’s only sold to enterprises and requires signing an NDA.
According to a VideoCardz reportRussian hardware repair expert VIK-on shared a product listing from Xianyu with them. As can be seen from the screenshot, the seller claims to offer an RTX 5090 96GB modification solution, and it is listed as a complete computer system, not just a single graphics card:

And in the center of the PCB in the photo is the NVIDIA GB202-300-A1, which is the GPU used by the RTX 5090. Around it is Samsung K4VCF325ZC-SC28 GDDR7 memory, with a capacity of 3GB per module and a marked speed of 28Gbps:

A standard RTX 5090 places 16 2GB GDDR7 chips around the GPU, for a total of 32GB, on a 512-bit memory bus. The PCB in this photo also has 16 chips on the front, but they have been swapped for 3GB modules, bringing the front side to 48GB. To reach the 96GB claimed by the seller, another 16 identical chips would have to be added to the back of the PCB.
However, the seller did not show the back of the PCB, so VideoCardz stated that this photo can only prove that there is indeed an RTX 5090 PCB modified with 3GB GDDR7, meaning at least 48GB is confirmed, but whether 96GB was actually achieved cannot be verified from the photo.
VIK-on believes this PCB was likely adapted from the RTX PRO 6000 Blackwell Max-Q design:

The RTX PRO 6000 Blackwell is a graphics card NVIDIA makes for professional workstations. It uses the same GB202 chip as the RTX 5090, but this card comes with 96GB GDDR7 from the factory. Since the same chip supports 96GB in the original design, it is not technically impossible. Therefore, the real difficulty is not the PCB but modifying the VBIOS.
In addition, the GPU in the photo also bears the date code “2532,” indicating it was produced in the 32nd week of 2025, which is already half a year after the RTX 5090 officially launched. Foreign media speculate that this chip was likely removed from an existing retail graphics card and then re-mounted onto a board.
The seller also stated in the description that they only accept inquiries from corporate clients, and buyers must sign a non-disclosure agreement (NDA). The price of RMB 6.48 million listed on the product page is just a placeholder figure, not the actual selling price; interested companies need to contact the seller privately to obtain a quote.
Do you really have to sign an NDA just to trade a modified graphics card? That seems a bit hard to believe, but this deal is a complete business-to-business package; in addition to the modified hardware, it very likely includes PCB schematics and a modified VBIOS.
