iGPU Overclocking Ability

[Seabass101]

Hi, I was wondering what is a safe voltage for a UHD 630 iGPU that comes from the i7 8700k? Also, what is the max voltage allowed for a iGPU UHD 630 that comes from the i7 8700k?

I am asking because my iGPU graphics has been a little buggy and many people have said increasing the voltage just a little bit dose help make it stable and fixes many issues, but I don't know what voltage to start with and what voltage is the max acceptable by this iGPU and the people that I have read from don't specify the voltages either.

Thanks

Hi, what is the range of a iGPU for max Voltage, max Wattage, and max overclocking Frequency it can be achieved at?

I have a i7 7700k and I would like to know this for the iGPU HD 630 that I am using....Cooler is H115i

Depending on the CPU (silicon lottery) & motherboard you may be able to get 5.0 ghz under 1.4V but if your using the system for gaming then you really need a dedicated GPU. Even something like the GTX 1050 or RX 560 would be a massive step up from the iGPU.
