What voltage limits are there for the Intel HD 4600 when overclocking?
I recently used liquid metal on my HP Probook 640 G1 and had a 23C tempture drop, which gave me room to overclock. I pushed my HD 4600 to its maximum, increasing from 1150Mhz to 1450Mhz with a small adjustment of 0.085v. When trying 1500Mhz, the system crashes within the first 15 seconds during benchmarking. I increased voltage in steps of 0.005v and noticed it lasts longer before crashing, but now it fails at 1500Mhz with 0.100v. How much voltage can I use without damaging the chip?
I wouldn't push it further because of the restricted CPU and VRM cooling, plus the likely lack of headroom for VRM output. The extra performance would probably be temporary, before the CPU, IGP, or VRM can no longer handle the overclocking requirements, which wouldn't extend the laptop's lifespan much beyond its current reliable state.
For more than basic gaming, you'd need a dedicated PC or at least a laptop with separate graphics. Even with overclocking, modern entry-level discrete GPUs won't match today's standards. The strongest IGP available now is the Ryzen 2400G, still only on par with a GT1030.
The system encountered an error because of insufficient CPU and VRM cooling capacity, along with limited VRM output headroom. This results in only modest performance gains, which may fade as the CPU, IGP, or VRM degrade over time. Extending its lifespan isn't worth sacrificing years of usability for this device. For more demanding tasks beyond casual gaming, a dedicated PC or laptop with discrete graphics would be necessary. Even with overclocking, achieving modern entry-level discrete graphics performance remains unattainable. The strongest IGP available today is the Ryzen 2400G, still only on par with a GT1030. My plan is to upgrade from an i5 4210M to an i7 4200M soon, paired with a GTX 950/960 E-GPU, so performance remains within reach. Currently, I use a watercooled i5 2500K with SLI GTX 670 as my primary setup. Running CS:GO at medium settings at 60fps and Fortnite at low to medium settings at 60fps is smooth enough for me. These extra frame gains are temporary and not critical for my needs.
