sus Rog G750JZ - Undervolted and overclocked - Questions

[navis995]

So I've managed to undervolt both CPU and GPU.
The CPU is now 10C lower with same performance while GPU is the same in temperature but I OC it and getting around 5fps increase in heaven benchmark.

The question is. As long the temperatures are the same as before OC and as long I don't see any artifacts or BSOD or crashes I am good to go with OC. And undervolting cannot damage electronic parts as far I found it either correct?

Thank you for the replies

navis995, the voltage range that the part operates correctly is just that, a range - at the top end it gets hot and crashes, and at the other end you risk a crash if you undervolt too far - but if you pick a voltage just above that crash point and it operates stably you have tuned the voltage to a custom value that is optimal - low enough to keep things cool and high enough to support stable operation.

The voltage isn't adjustable for the GPU. It may appear to be adjustable if a slider is there and shows a number change when you move it, but if you watch the GPU voltage with a monitoring program you will see the voltage varies around the default value. It doesn't hurt to "set it", but a change isn't being applied.

Have fun 🙂

Thank you for reply.

Well the CPU which is i7 4700hq is now at 3,3GHz on full load 100& around or under 90°C with all cores on 33 multiplier in comparison to the previous one where it was 3,2 with up to 98°C.

While the GPU, you said it doesn't affect it. You mean the low end is set but the higher end still prevails? Then yes, at least that's what I saw. Anyway the GPU which is 880M is now OC with memoryclock at almost 3000mhz and core clock at 1050mhz while the temperature is the same as before on default clocks if not the same.

So far everything is great and fantastic and I spent only around 2h doing it.

navis995, sounds great, and yes it is quick and easy process once you are familiar with it.

The voltage will go up/down as part of the normal operation of the GPU, the adjustable voltage setting has no effect.
