Good day I have an Dell Ispiron 14 7447 laptop with Core i5 4200H cpu, 4GB RAM and a GTX 850M GDDR3 gpu memory. (Cpu and Gpu I think is SOLDERED into.the board)

- I saw that my Memory data rate only speed up to 900 MHz (1800 MHz effective)
If I overclock my memory speed to 1000 MHz (2000 MHz effective) (other laptoos have 1000 MHz memory speed) will it be okay not cause any damage because 1000 MHz is default in nVidia website.

- Since GTX 860M, 850M and 960M, 950M are the same lets say I overclock my GTX 850M gpu clock to same as 860M and 950M (GDDR3) will it cause no harm? Cause if you look at it there all the same chip and 950M, 960M looks like an overclock 850M, 860M and has same chip its just like 850M is low power 860M same as 960M and 950M will oc safe because of same chip tech? The only difference is Gpu clock maybe watts plus type of memory but the chip are all the same.

- If temps, voltage are same after Oc and didnt increase ONLY FREQUENCY increased will it be okay and cause no harm in the motherboard and lifepan of the laptop in the near future?

- I only wanted 1000 MHz instead of 900 MHz in Memory clock I dont know if Dell used slower and cheaper or they just underclock it. Other perople who have HP Envy 15 has same problems with memory clock being lower than normal nVidia config.

Thank you for answers.

They probably used the same memory, but the other problem is the cooling and the PSU. Laptops always have inferior cooling, if we imagine a laptop with a 500W PSU, it still won't be able to reach a lot because of the airflow limit. And now for the power, most of the laptops work on around 90W~200W, meaning that the PSUs follow the other specs. In other words, this means that a laptop with more powerful parts will also have a proportionally more powerful PSU. If you try increasing the clock nothing bad will probably happen, as long as you don't make too high jumps, if the system is unstable then it's the real limit.
