We stressed the notebook and enabled the monitoring tools CPU-Z, GPU-Z and HWiNFO64 in order to identify any instability or throttling issues. With only Prime95 active, the CPU was observed to be operating at its advertised 3.2 GHz speed for four active cores. A minute into the stress test, however, the CPU dropped to the 2.9 GHz to 3.1 GHz range. While still significantly above its base 2.4 GHz speed, the notebook was unable to sustain maximum Turbo Boost under any sort of sustained maximum stress.
With only FurMark active to stress the GPU, the GTX 770M was observed to be running at 836.1 MHz, but will similarly drop and stabilize to a lower 810 MHz speed after a minute or so.
Under full stress conditions (Prime95 and FurMark active simultaneously), the CPU and GPU dropped to 2.8 GHz to 2.9 GHz and 796.9 MHz, respectively. Both processors never dipped below these operating clock rates even after a full hour of stress, thus concluding no throttling issues. The CPU and GPU maintained stability at 92 to 95 degrees C and 83 degrees C, respectively, though the system fan kicked in at noticeably higher RPMs whenever CPU temperatures do reach 95 C. A 3DMark 11 run immediately following the stress test returned no significant drops in final scores.
这叫没问题?这还只是75W的770M...M290X只会更严重
