I purchased a Bosgame M5 BeyondMax…
I purchased a Bosgame M5 BeyondMax system specifically for running local AI models and long-running Ollama workloads. Unfortunately, the computer repeatedly performs sudden hard shutdowns during sustained local LLM inference. The system does not crash gracefully, show a useful error message, or leave a normal software log. It simply becomes unavailable and has to restart or be powered on manually. To determine whether this was an isolated hardware defect, I asked the support to get a new product in excchange. They refused - I should send the old one back on my coists, they will examine and without getting to know how long this will take, theymight ship another one. As I use this server as a testing and development machine, I do not want to wait so long for another one. So I purchased a second M5 unit - as support told me I will get my money back, when I'm sending the server back again. The second unit exhibited the same behaviour under the same controlled workload. This strongly suggests a platform-level stability problem rather than a defect in one individual computer. I tested different software versions, including different Linux kernels, updated graphics firmware, ROCm versions and Ollama versions. The issue remained. I also tested the BIOS “Balanced” profile at approximately 85 W. This only delayed the failure; it did not solve it. In my tests, the system still shut down after sustained AI load. I provided Bosgame support with detailed logs, hardware telemetry and a reproducible test package. The package included the exact workload, configuration and instructions needed to reproduce the problem. Despite this, I did not receive a meaningful technical resolution, a firmware solution, an acceptable replacement arrangement or an appropriate price reduction for the unit I kept. I returned the second computer under the 14-day withdrawal period. Although I eventually received the purchase price back, the refund took several weeks, and I did not receive reimbursement for the outbound and return shipping costs, which together amounted to more than €100. I understand that intermittent hardware problems can be difficult to diagnose. However, the combination of repeated failures on two units, extensive evidence provided to support, and the lack of a satisfactory response has been extremely disappointing. Based on my experience, I cannot recommend this product for reliable 24/7 local AI workloads, and I cannot recommend Bosgame as a business partner when technical problems arise.
