Posted May 7May 7 Hello!! I've been doing some CO tuning to my 5800X3D (system specs below) and also I did some RAM OC with my CPU at stock. In both cases, the stress test I always fail is N63 from YCruncher. I don't know exactly what component this test stresses, since the sensors of my board show that energy, RAM and CPU usage are at "normal" levels, but I fail N63 everytime. What made me think about this test was that when I was testing my RAM OC (CPU stock) I had several reboots and Event Viewer always pointed to a random core crashing... which I couldn't wrap my head around it since my CPU was at stock and my system is perfectly stable at stock settings (tested for 48hrs straight). It's also important to say that my RAM OC has passed 50 Cycles of TM5 (1usmus_v3), 20 cycles of Anta777's absolut and 15 cycles of Anta777's extreme, so it isn't at borderline stability. So I'd like to understand what does exactly N63 test stresses so I could make the proper tweakings. Thanks!! @Mysticial (5800X3d + Aorus Elite WiFi X570 Rev. 1.x + 32GB DDR4 Crucial Ballistix Sport + 1000W Seasonic Focus Gold)
