Two of five CMP 170HX died in two weeks and a third shipped with defective tensor cores
r/LocalLLaMA·low signal
An r/LocalLLaMA owner reports a 40% two-week failure rate across five CMP 170HX cards, with a third arriving already broken (defective tensor cores), and concludes current prices do not justify the purchase. The post drew 104 upvotes and 74 comments, alongside a separate CMP 170HX build thread the same day, which suggests the used-mining-card route is getting fresh attention exactly as the Ascent GX10 and DGX Spark price hikes push people toward cheaper compute. Single-source anecdote on a small sample, so treat the rate as a warning rather than a statistic.
