Lenovo ideapad 300-17ISK Memory upgrade

Hello. 

 

With a problem related to a gaming in DeusEx Mankind Devided on my Lenovo ideapad 300-17ISK with only intel HD 520 graphics I want to ask a question: how many memory dedicated to my graphics from RAM when very hungry application runed on Windows 10 x64?

 

In CPU specs it value fixed on 32Gb max thats maximum of CPU support.

 

I whant ask how many memory can my laptop dedicate to HD 520 when I use 4Gb of RAM or 8Gb of ram.

 

Second question is about can my laptop support DDR4 memory or only DDR3L is avalible because I wanth to upgrade it. And what performance changes I can see if I upgrade a memory to DDR4 or improve a memory size? Have my laptop an option to incrase a dedicated VRAM to a value of 4Gb?

 

Because it is a minimal system requirements to play DeusEx Mankind Devided.

 

Please give me the answers ...

Re: Lenovo ideapad 300-17ISK Memory upgrade

I was found a solution for increase a VRAM size.

By default an integrated graphic card only have a 128Mb of dedicated VRAM.

In some games we have an deficit effect thats makes the sound of wheezing.

I just add a key to registry from this manual and increase a VRAM to 512Mb and the sound almost ceased to wheeze.

I was add a request for new modded drivers HD 520 graphics to get a maximum of dedicated VRAM of 1024 or 2048 Mb and maybe with modded drivers we can play Mankind Devided.

I am very sorry that 300-17ISK is not supported DDR4.

After memory upgrade and using moded drivers I will write how it about performence in DEX.

I want wo ask. Does my laptop support a high frequency DDR3L like a kingston 2133 Mhz or it will works on 1600 Mhz instead?

Have any reason to bye this module?

In spec(https://download.lenovo.com/consumer/mobiles_pub/ideapad_300-14isk_300-15isk_300-17isk_hmm_201610.pd...) this value is : "Memory Type and speed DDR3L-1333 MHz/1600 MHz" but can this motherboard work faster or not?

Re: Lenovo ideapad 300-17ISK Memory upgrade

So. Lenovo 300-17ISK steel manage of 32Mb dedicated DVMT memory for internal graphics that is so small for installing MacOS sierra and in couple with blocked to rewrite BIOS and undefined Intel USB 3 drivers is ugly hardware.

 

Do not buy this laptop if you want to intsall Mac OS. It will stop updating on El Capitan 10.11.6.

 

Amen.
