The shop has a very uninspired name that roughly translates to "AI to GPU Expert," since they take regular gaming cards and transform them into AI workhorses with a lot of VRAM. They operate out of Saitama Prefecture and have a store on Mercari where you can find a bunch of different modded GPUs listed for rather reasonable prices.
The cheapest pre-modded RTX 2080 Ti we could find was an MSI Venus 2X model for $428 . Just a few days ago, we saw blower-style 22GB RTX 2080 Ti SKUs listed for $500 on eBay from a Hong Kong seller. It's hard to get your hands on memory for a fair price these days, but it seems like this vendor has a very generous plug based on their prices.
They even posted about recently receiving a large shipment of 2GB GDDR6 modules made by Samsung, all intended for upgrading RTX 2080 Ti cards. The batch included 200 modules, so 400GB of extra VRAM that should be enough to upgrade 36 different RTX 2080 Ti cards to 22GB. Just an hour later, they had already upgraded the first card:

Replying to a comment , the shop clarified it charges 45,000 Yen for this service, which works out to $282.48 — that's $25.68 per GB of extra VRAM, or $12.84 per GB for the entire 22GB pool. All things considered, not a bad price at all. You can very easily find stock RTX 2080 Ti cards for less than $250 on the secondhand market, so the total cost of a 22GB card would work out to a little over $500.
GPU repair service will upgrade the 11GB VRAM on an RTX 2080 Ti to 22GB with a new, stable BIOS
