An RTX 2080 Ti VRAM Upgrade to 22GB Costs $282 in Japan — and 200 Samsung Chips Just Landed

A Japanese repair shop in Saitama Prefecture is charging 45,000 yen ($282) to upgrade an RTX 2080 Ti's VRAM from 11GB to 22GB, using 200 Samsung 2GB GDDR6 modules it received on August 15. The mod, which involves replacing eleven 1GB chips with eleven 2GB chips and rewiring strap resistors, turns the 2018 card into a budget AI powerhouse, with pre-modded units selling for as low as $428.

Eleven 1GB modules come off, eleven 2GB Samsung chips go on, the strap resistors get rewired, and a 2018 flagship turns into a cheap local-AI card. The GeForce RTX 2080 Ti has quietly become the most-modified graphics card of its generation, and a shop in Saitama Prefecture has now put a plain price tag on the work. An RTX 2080 Ti VRAM upgrade from 11GB to 22GB runs 45,000 yen there, about $282, or roughly $25.68 for every extra gigabyte. Send the card in, get it back with double the memory and firmware that knows what to do with it. The shop’s name translates to something close to “AI to GPU Expert”, and it sells finished cards through a Mercari storefront alongside the upgrade service.

That is 400GB of memory, enough to convert 36 cards. The first one was on the bench and under test roughly an hour later. Why it is always the 2080 Ti Turing’s TU102 addresses memory over a 352-bit bus, which works out to eleven 32-bit channels and eleven 1GB GDDR6 packages. That awkward 11GB figure has irritated spec-sheet readers since 2018 and delighted modders ever since, because every channel is fed by exactly one chip. Double the density of all eleven and the pool doubles with it: 22GB on the same bus, at the same bandwidth. The memory is the easy part. Convincing the card that the memory is there is not. Density is signalled by strap resistors on the PCB, so whoever takes the job has to rework those alongside eleven BGA packages, then flash a BIOS built for the new configuration. Tom’s Hardware documented the same procedure in July https://www.tomshardware.com/pc-components/gpus/gpu-repair-service-will-upgrade-the-11gb-of-vram-on-your-rtx-2080-ti-to-22gb-mod-involves-physically-adjusting-the-strap-resistors-on-the-pcb-to-support-a-new-bios at GPU Solutions, a UAE shop that hands over the matching BIOS up front. Botch any stage and you own a very expensive paperweight. The maths only works because memory got expensive A used 2080 Ti sells for under $250 in most markets, so the full do-it-yourself route lands near $530 for a 22GB card. Skipping the queue is cheaper: the least expensive pre-modded unit listed was an MSI Venus 2X at $428, and blower-style 22GB cards turned up on eBay at $500 from a Hong Kong seller. None of this is a gaming argument. Turing is three architectures old, its ray-tracing hardware belongs in a museum, and 22GB will not add a single frame to anything you actually play. For running models locally it reads completely differently. Capacity, not shader throughput, decides whether a model loads at all, and 22GB clears a tier of quantised checkpoints that 11GB cannot hold no matter how patient you are. What makes it land this month is the memory market itself. GDDR and DRAM contract pricing has climbed all year, hard enough to keep older platforms commercially alive and to squeeze the budget end of the graphics card market. Against that backdrop, a small repair shop that can source 200 Samsung packages and still charge $25 a gigabyte looks less like a curiosity and more like access to a supply chain most buyers simply do not have. Whether that access lasts is the more interesting question.
