深圳华强北商家声称可改装96GB显存RTX 5090，售价约8200美元，但VBIOS兼容性未确认
英文摘要
A visitor to Shenzhen's Huaqiangbei electronics market inquired about rumors of 96 GB GeForce RTX 5090 cards. One seller said they could modify a standard RTX 5090 (36,000 yuan) by swapping in 96 GB of VRAM for an additional 20,000 yuan, bringing the total to approximately 56,000 yuan ($8,200). The vendor claimed a one-week lead time but did not demonstrate a working card. The post highlights that the VBIOS may not recognize the extra memory, making the modification infeasible, and no confirmation of a functional unit was obtained.
