Reddit User Discovers 12 RTX 3070 GPUs from Crypto Mining Rigs in Basement Storage
Key points
- 12 Zotac RTX 3070 GPUs found in old crypto mining rigs.
- Cards stored in a basement since Ethereum mining became unprofitable.
- Minor silicone bleeding observed, but GPUs are likely salvageable.
- User plans to test and sell most of the cards.
Discovery of Mining Rigs
A Reddit user reported finding two cryptocurrency mining rigs containing a total of 12 Zotac-branded Nvidia RTX 3070 graphics cards. These rigs were reportedly used during the COVID-era mining boom and subsequently stored in a basement after Ethereum mining became unprofitable.
Condition of the Hardware
Despite years in basement storage, the components, including an MSI MPG Z390 Gaming Plus motherboard, a 1000W Rosewill power supply, DDR4 RAM, and SSDs, appear largely undamaged. The RTX 3070 GPUs exhibit minor silicone bleeding, a common issue from thermal pad breakdown, but are considered salvageable with cleaning and replacement of thermal pads and paste.
RTX 3070 Specifications and Mining Use
The RTX 3070, launched in 2020, features Nvidia's Ampere architecture with 5,888 CUDA cores and 8GB of GDDR6 memory. It was popular for 1440p gaming and also attractive to cryptocurrency miners due to its performance and power efficiency. GPUs used in mining often operate at reduced voltages and power, potentially reducing stress compared to typical gaming use.
Future Plans for the GPUs
The discoverer intends to individually test all 12 RTX 3070 cards to determine their working condition. If most are functional, the user plans to sell 10 or 11 of them, keeping at least one. The total haul represents 96GB of VRAM, which is considered valuable given current GPU market prices.
