Greg Sky posted a short claim on X on October 31.
Sky runs GPU Lab, a repair shop in Grand Rapids, Michigan. He already sells modded RTX 4090 cards with 48GB of memory. The stock RTX 5090 from Nvidia ships with 32GB.
Sky's post read simply: '64 and 96gb 5090 confirmed.' He shared the claim alone. He skipped any photo, benchmark, or chip diagram.
The claim landed fast. Sky's post pulled 5,919 likes and 174 replies within days.
Three days earlier, Sky had posted the opposite view. He called a 96GB RTX 5090 fake, based on a chat with a contact in China. He reversed that view in his new post.
A Reddit user named MundanePercentage674 shared the story on r/LocalLLaMA today. The post links to a TweakTown report on Sky's claim. It pulled 103 comments fast.
Commenters in the thread want hard proof before they believe the claim. They asked for a GPU-Z screenshot, a working card, or a verified seller. GPU-Z is a free tool that reads a card's real memory size. That proof has yet to surface.
Wikipedia's page on the GeForce RTX 50 series drew 1,041 views on November 2.
Local AI builders watch VRAM size closely. More memory lets a computer run bigger AI models at home, with fewer workarounds. A jump to 96GB would let one card hold models that once needed two or three cards.
Sky has a real business reason to talk up bigger memory mods. His shop already sells similar upgrades for older Nvidia cards.
The claim still carries real weight for one simple reason. A named repair shop, rather than an anonymous account, put its name on the number. That name pulled thousands of likes before a single photo backed it up.
