Modded RTX 5090 With 96GB GDDR7 Memory Appears on Chinese Marketplace

According to ExtremeTech, a Chinese marketplace has hosted a listing for an RTX 5090 video card equipped with a reported 96GB of GDDR7 RAM.

The Tech TL;DR:

• A modified RTX 5090 card featuring 96GB of GDDR7 memory appeared on a Chinese marketplace.
• The modification triples the original 32GB capacity, matching the RTX Pro 6000 and creating a potential alternative for AI training.
• The seller’s listing includes a confidentiality agreement requirement, likely to protect a custom VBIOS.

Should the claims prove accurate, the hardware alteration multiplies the standard 32GB supply of the RTX 5090 by three, equaling the 96GB found in the RTX Pro 6000 while transforming it into a more powerful processor for AI inference and training tasks. Recently, online storefronts have seen RTX 5090 video cards nearly vanish entirely, causing costs to surge past $7,000. It’s not been clear why that’s happened, beyond perhaps Nvidia curtailing supply.

Documentation from VideoCardz revealed images of the altered hardware featuring a GB202-300-A1 processor, specifically an RTX 5090 GPU stamped with a 2532 date code denoting the 32nd week of 2025.

That probably means it began life as an RTX 5090 gaming card before its conversion. The board now hosts 3GB Samsung K4VCF325ZC-SC28 GDDR7 chips arranged with 16 units on either side. That’s 50% more capacity per chip and double the number of chips.

While the person behind the alterations did not disclose their modification technique, the advertisement indicates that prospective purchasers must execute a nondisclosure agreement. VideoCardz speculates that that could be about not sharing the custom BIOS the card would have required. Building the VBIOS was highlighted by an informant of VideoCardz as potentially the most difficult phase of this hardware overhaul.

As the initial 96GB RTX 5090 documented publicly, skepticism remains regarding whether the hardware could be fabricated or fraudulent. Nevertheless, rather than a low-resolution capture shared across social media platforms, this constitutes an active commerce entry where the vendor appears to be gathering bids.

The price is a placeholder, since it’s the equivalent of several hundred thousand dollars. Anticipated pricing for the unit would likely exceed a standard RTX 5090 while remaining under the cost of the RTX Pro 6000 it seeks to replicate.

“We won’t know for sure unless a lot more of these cards start showing up, but this first one is intriguing,” Joseph Maldonado told PCMag.
