Intel HD 4600 Overclock... How far can I got with the voltage?

[DavidVioMC]

Recently I have liquid metal my HP Probook 640 G1 and I have 23C tempture drop which opened some room for overclocking. I decided to overclock my HD 4600 to it's limit, I went from 1150Mhz stock speed to 1450Mhz with extra 0.085v.

I tried pushing it to 1500Mhz but it seems to crash in first 15 seconds of benchmarking, I tried applying more and more voltage, 0.005v at a time and it appears the more I apply the longer it will survive the benchmark before crashing but now I have gotten to the point where it crashes at 1500Mhz with 0.100v. How far can I got with the voltage before I run into the risk of frying the chip? Thanks

I wouldn't bother pushing it any further due to limited CPU and VRM cooling, and likely limited VRM output capacity headroom. Getting limited extra performance, possibly for only a limited time before the CPU/IGP/VRM deteriorate and can no longer accommodate the OC, isn't worth shaving years off an otherwise still perfectly usable laptop's life.

If you want to get into more than non-trivial gaming, you'll have to either get a PC or at least a laptop with discrete graphics. No amount of overclocking is going to give you anything resembling modern entry-level discrete graphics performance. The most powerful IGP on the market today is the Ryzen 2400G and that's still only comparable to a GT1030.

I plan to upgrade the CPU from i5 4210M that is in it right now to i7 4200M in very near future with GTX 950/960 E-GPU, this is why the life span is not really on my priority list. I just want to squeez as much performance out of this chip while I can, I have a watercooled i5 2500k with SLI GTX 670's as my main rig, so if I want to run something that this laptop can't, I just go to my desktop. This laptop runs CS:GO on medium settings at 60fps very smoothly and Fortnite on low to medium settings at 60fps too and gaining those extra 5-10fps would be fine by me, it's more of a temporary thing than anything.

If you are going to upgrade the laptop's CPU "in the very near future" then I'd argue that's one more reason not to risk frying the VRM first.

There are some laptop overclockers at Notebook Review. you might get some more specific info. there.
