Samsung-branded 24 Gbit (3 GB) GDDR7 memory chips have surfaced in the Chinese retail market, sold individually despite originating in OEM packaging intended for automatic PCB assembly. At a listed price of RMB ¥72.50 per chip, this unprecedented accessibility is drawing attention from graphics card enthusiasts and memory modders. The availability allows for the theoretical expansion of video memory—enabling modders to boost the GeForce RTX 5090’s memory from stock capacity to as much as 48 GB through manual upgrades. Such an upgrade could substantially enhance the performance of Artificial Intelligence models requiring higher memory bandwidth and larger parameter counts than standard configurations permit.
Parallel to these developments, China´s growing market for off-brand and gray-market RTX 5090 graphics cards adds fuel to the trend. These cards often feature board designs targeting commercial Artificial Intelligence acceleration farms, sometimes shipping with significantly increased memory. The unrestricted sale and modification of these components come amid U.S. export controls that prohibit NVIDIA from officially selling the RTX 5090 in China. As a workaround, NVIDIA offers the RTX 5090D domestically—a variant with similar gaming prowess but deliberately hampered Artificial Intelligence acceleration and blockchain capabilities to comply with regulatory restrictions.
Despite these controls, demand for high-performance hardware in sectors like Artificial Intelligence and advanced computing persists. The loose distribution of advanced memory chips like Samsung’s 3 GB GDDR7 units enables both end users and commercial entities to sidestep official supply limits and create powerful, customized solutions. This gray-market activity not only raises questions about enforcement effectiveness but also demonstrates the technological ambition and resourcefulness within Chinese modding and Artificial Intelligence communities. The direct availability of such high-capacity memory further blurs the lines between official product capabilities and bespoke, community-driven enhancements, challenging hardware manufacturers’ control over their technology in global markets.
