A heavily modified NVIDIA GeForce RTX 5090 graphics card with a claimed 96GB of GDDR7 memory has appeared on a Chinese online marketplace, potentially offering three times the memory capacity of the standard gaming GPU.
The unusual graphics card was reportedly listed on Goofish as part of a complete PC system, with sales restricted to business customers.
However, the seller has not provided independent evidence confirming that the modified card works as advertised.
Photographs accompanying the listing show what appears to be an NVIDIA GB202 GPU surrounded by high capacity Samsung GDDR7 memory modules.
Although the hardware configuration appears technically possible, questions remain about the graphics card's firmware, stability and actual memory capacity.
Modified RTX 5090 Uses Samsung 3GB GDDR7 Memory Modules
The standard GeForce RTX 5090 comes with 32GB of GDDR7 memory, making the alleged 96GB configuration a substantial upgrade.
According to the listing photographs, the modified board contains an NVIDIA GB202-300-A1 processor, the same GPU used in the retail RTX 5090.
The visible memory chips are identified as Samsung K4VCF325ZC-SC28 modules.
Each module provides 3GB of GDDR7 memory and is rated for speeds of up to 28Gbps.
The photograph shows 16 memory packages positioned around the GPU, providing a total of 48GB on the visible side.
To reach the advertised 96GB capacity, another 16 memory modules would need to be installed on the reverse side of the circuit board.
However, the available photographs do not show the back of the card, leaving the complete memory configuration unconfirmed.
RTX PRO 6000 Blackwell Board Could Make the Modification Possible
Hardware modder VIK-on, who shared the listing, believes the graphics card may use a circuit board derived from NVIDIA's RTX PRO 6000 Blackwell Max-Q.
That professional GPU already supports 96GB of GDDR7 memory, making its board design a possible foundation for the modification.
The main challenge would reportedly involve adapting the graphics card's VBIOS to recognize and operate the larger memory configuration.
Simply installing additional memory chips would not guarantee that the GPU could access the full capacity.
Firmware compatibility, memory configuration and hardware stability would all need to be addressed.
VIK-on considers the modification technically feasible but also warned that the marketplace listing could be fraudulent.
Alleged 96GB RTX 5090 Targets Business Customers
The seller has reportedly restricted purchases to commercial customers and requires interested buyers to sign a confidentiality agreement.
The advertised price is also described as a placeholder rather than the actual selling price.
Companies interested in purchasing the system must contact the seller directly for further information.
| Specification | Standard RTX 5090 | Alleged modified RTX 5090 |
|---|---|---|
| GPU | NVIDIA GB202 | NVIDIA GB202-300-A1 |
| Memory capacity | 32GB | 96GB claimed |
| Memory type | GDDR7 | GDDR7 |
| Memory module capacity | 2GB | 3GB |
| Memory packages | 16 | 32 required |
| Availability | Retail graphics card | Unverified business listing |
The GPU shown in the photograph also carries a manufacturing date code corresponding to the 32nd week of 2025.
This suggests the processor was packaged in 2025, although it does not establish whether the chip originated from a retail graphics card.
Chinese GPU Modifications Continue to Target AI Workloads
Chinese hardware manufacturers have previously modified consumer NVIDIA graphics cards for specialized computing applications.
Some operations reportedly remove GPUs and memory components from retail RTX 5090 cards and install them on redesigned circuit boards intended for AI systems.
Such modifications can offer alternative hardware configurations for workloads requiring substantial graphics memory.
A functioning RTX 5090 with 96GB could be particularly useful for running large AI models, where memory capacity can be a significant limitation.
However, the latest listing does not include verified benchmarks, operating system screenshots or demonstrations confirming that the GPU recognizes all 96GB.
For now, the photographs provide evidence of an unusual graphics card assembly, but they do not establish that a working 96GB RTX 5090 is commercially available.
