New to the undervolting scene, but I recently decided to repaste and undervolt my Spectre x360 15 for better performance, as it often gets hot and turns on the fans even when not under load (browsing the Internet, or even idle). Currently, I'm running at a stable -80mv undervolt on core and cache, and I've repasted with Thermal Grizzly Kryonaut.
Benchmarking with AIDA64 (CPU, FPU, Cache), the laptop will boost to maximum clock for around 3 or 4 seconds (25W pkg power) before dropping to just above its base clock (15W). A few minutes later, it'll start throttling down (pkg power slowly drops to ~13W, clock speeds follow), maintaining temperatures around 65C, despite not showing throttling in AIDA64. ThrottleStop's limit reasons show that it hits red on PL1 and EDP OTHER almost immediately after beginning the stress test.
Putting load on the iGPU along with the CPU makes it throttle even harder, dropping clocks to below 900Mhz after only a few minutes.
Optimally, I'd like the laptop to be able to maintain its boost clock for much longer (especially since it has almost 30 degrees of thermal headroom), and I was wondering if anyone had any suggestions for what I could try. I've attached screenshots of AIDA64 and ThrottleStop (after a long stress test on the CPU) below.
