Upgrade

[Perooo]

I have hp elitebook 840 g3 with i7 6600u need to know the upper processor i can change to it to take more performance with my laptop need to know the higher processor i can put it on my laptop

[Huffer]

The processor is soldered to the motherboard and not removeable or upgradeable. In your case you cannot even move up by replacing the motherboard as the i7-6600U was the top offering on that model so there is no better motherboard that has been made.

So i have to change the motherboard

I did not say that in fact I said even by changing the motherboard you cannot have any faster processor. The i7-6600U is the top of the line for that model series and the motherboard is a unique piece of hardware made for that laptop and no other so there is no other hardware you can buy. You already have the best there is. To have a faster processor means a different laptop.

Its a pretty capable processor. What problem are you trying to solve by upgrading it? Perhaps a memory upgrade or a solid state drive would get you where you need to be.

I need to upgrade the graphics on it and I think that if I change the processor it will give me high graphics than hd 520 or i need any other solution to get little better graphics

[Huffer]

Thats what I thought you might be doing. The 840 G3 only supports the Intel HD 520 video and that chip is also soldered onto the motherboard. So even if you could upgrade the processor it would not affect the video enough to be even noticeable. The laptop is not a gaming machine or even an engineering workstation for CAD and such and there is no way to make it into one.

I know i don't need gaming laptop i just need little better grapichs even it was with some changes by the software

[Huffer]

I don't know what you need to do but there is just really no way to make the video better or faster with software. You can update the driver but that just makes little technical changes and will not make the framerate any faster on games.

It's just if I'll play I'll play pes18 and for some rendering and official works and photo editing

Buy a different computer and perhaps sell the one you have then. There is no dedicated GPU available in this series and it is rarely economic to change the system board. Driver changes might tweak things very slightly, but will not increase the underlying power of the GPU.

The Core i7-6600U was a good processor for its day; it powered what was my main system for most of the past two years. It is only two generations behind what is current today and is still an excellent workhorse. The problem is that you simply cannot make a modest integrated GPU perform like a powerful dedicated GPU.
