Modders are selling RTX 2080 Ti GPUs with 22GB VRAM on eBay for AI use

A Hong Kong-based eBay seller is now selling GeForce RTX 2080 Ti cards modded with 22GB of VRAM, double the 11GB the card shipped with back in 2018. The listing costs $499 and promises a working "Turbo" blower-style card, though buyers won't get to pick the brand. The seller's description says the card could be a GIGABYTE, MSI, ASUS, Leadtek, or whatever happens to be in stock that day.

Listing photos show a GIGABYTE blower card alongside a box stacked with modded units ready to ship, plus a GPU-Z screenshot confirming 22,528MB of memory on a running card. The seller's feedback score sits at 99.6 percent, and buyers on the listing itself, at least 38 of them, report the cards work as advertised.

VRAM mods like this trace back to modders in China, where cards like the RTX 4090 have been effectively banned from export under US sanctions. Rather than let older or restricted hardware go to waste, some workshops there have been stripping cards down, swapping in higher capacity memory chips, and reselling them with server-friendly blower coolers built for AI racks rather than gaming rigs.

The appeal for local AI users is straightforward. Running large language models or diffusion models locally is mostly a memory capacity problem before it's a raw compute problem. The 22GB gives the RTX 2080 Ti's Tensor Cores and memory bandwidth enough headroom for LLM inference, even if the card's older precision support makes heavier diffusion workloads slower.

For consumers hunting for budget AI hardware, that $499 price still looks decent next to the alternatives. A 24GB Titan RTX runs about $800 on eBay right now, a 24GB Quadro RTX 6000 is close to $900, and a 24GB RTX 3090 is selling for around $1200. Modern RTX Pro cards with more VRAM cost considerably more.

It's also a reminder that NVIDIA's Tensor Core architecture, present in every GeForce and workstation GPU since Turing launched in 2018, keeps finding new uses well past its original shelf life. That's good news for AI hobbyists on a budget, though it could mean less stock 2080 Ti supply left over for gamers just looking for a cheap secondhand upgrade.

Question #1

How did modders increase the RTX 2080 Ti from 11GB to 22GB — swapping memory chips or another method?

They increased the RTX 2080 Ti to 22GB by swapping in higher-capacity memory chips. The article notes listing photos and a GPU-Z screenshot confirming 22,528MB, and it traces these VRAM mods back to workshops that strip cards and swap in larger memory modules.

Answered

Question #2

Will a 22GB modded RTX 2080 Ti be capable of running common LLMs and diffusion models for local inference?

Yes. The article states that the 22GB gives the modded RTX 2080 Ti enough headroom for LLM inference, though the card's older precision support will make heavier diffusion workloads slower. It presents the modded 22GB 2080 Ti as a solid budget option for running local AI models.

Answered

Question #3

How does the $499 price for a 22GB modded 2080 Ti compare to other high-VRAM options available on eBay?

The $499 price is considerably cheaper than other high-VRAM options on eBay cited in the article. A 24GB Titan RTX runs about $800, a 24GB Quadro RTX 6000 is close to $900, and a 24GB RTX 3090 is selling for around $1200, with modern RTX Pro cards costing considerably more.

Answered

Question #4

What risks or compatibility issues should buyers be aware of when purchasing a VRAM-modified GPU from this seller?

These cards have had higher-capacity memory chips swapped in, so they carry the limitations of the older RTX 2080 Ti architecture, specifically the article notes the card’s older precision support can make heavier diffusion workloads slower. The cards are sold as blower-style, server-friendly coolers rather than typical gaming coolers and buyers cannot choose the brand of card (it may be GIGABYTE, MSI, ASUS, Leadtek, or whatever is in stock). Also be aware of broader market risks around fake or scam GPUs as noted in the related article "Watch out for fake GPUs more than ever, as scammers try to take advantage of higher prices."

Given the stock on hand, this Hong Kong outlet seems to be a serious operation rather than just one modder swapping memory modules just for fun. So, if you're in need of lots of VRAM on a budget, and want to run local AI models, then these modded RTX 2080 Tis seem to be a solid option.
