Laptop Panel Overclock ability dependent on CPU/GPU?

Hi,

I have been running laptop panel overclocked from 60Hz to 97Hz for a few months now and I've been very happy with it. Recently someone on these forums implied that the bottleneck in how far they could OC their panel was something to due with their integrated graphics on their CPU. I ordered a new CPU and GPU for my laptop, and now I am worried that potentially the new CPU will not allow me to OC my panel to 97Hz again. Can someone shed light on this?

Thanks!

 

Certain systems only have iGPU driving the panel with the GPU supplying demand instead of a dG{U (known as dGPU or PEG modes). IIRC this all started as some kind of lawsuit between Intel and Nvidia a long time ago. The result was Optimus.

Overclocking the panel is much easier if you have a dGPU solution most of the time. As Intel didnt really follow through on their promise of panel OC's in iGPU solutions until much later and only as far back as Haswell. iGPU can simply deny panel OC if the driver doesnt allow for it.

Though there are more experienced members doing this sort of thing than I. This is just my understanding of it.

That all being said, OC isnt guaranteed so its all up to the lottery when the cards hit the table.

 

I have found the GPU to not matter as long as you are not exceeding what it is rated for. It's the quality of the panel which limits the overclock, assuming you can overclock it in the first place.

 

GPU doesn't matter, all about panel. I have an Alienware M18xR2 with iGPU/1060 (Oprimus) and my brother has the same laptop with 680M SLI (direct connection).

His panel overclocks to 80hz using nvidia control panel. Mine overclocks to 85Hz using a flashed EDID.
