Modded Nvidia RTX 5090 with 96 GB VRAM and custom BIOS surfaces in China
The Nvidia GeForce RTX 5090 has been shoehorned with a staggering 96 GB of VRAM—the same capacity as Nvidia's much more expensive RTX Pro 6000 Blackwell. Not great news for Nvidia, which is already going through something akin to a crisis.
As reported by VideoCardz, hardware repair specialist VIK-on spotted the listing on Xianyu, Alibaba's secondhand marketplace. The seller, based in Changsha, China, is advertising a complete 96 GB RTX 5090 modification package that reportedly includes custom PCB schematics and modified BIOS firmware.
The asking price is listed at a ridiculous 6,488,888 yuan, which is merely a placeholder. The seller explicitly states that actual pricing will be negotiated privately and that the offering is intended exclusively for business customers.
Prospective buyers must reportedly identify their companies and agree to confidentiality requirements. The seller also claims that hardware testing can be arranged through intermediaries. Individual customers are explicitly discouraged from making inquiries.
Images accompanying the listing show what appears to be 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 capacity.
This isn't the first time a 96 GB RTX 5090 has appeared online. A similar Alibaba listing surfaced in September, although its contradictory memory specifications raised questions about its authenticity.
We recently covered how Chinese workshops have been dismantling retail RTX 5090 graphics cards and transplanting their GPUs onto custom boards intended for AI servers.
With 96 GB of memory, a modified RTX 5090 could accommodate far larger AI models than the standard 32 GB card, sans the professional features of an RTX Pro 6000. Still a meaningful upgrade for a supposedly discontinued GPU.
Unfortunately, there is still no independently verified demonstration of this particular 96 GB modification functioning as advertised. And even if someone does get it up and running, they're unlikely to run Cyberpunk 2077 on it to show it off its raytracing chops.
