Upgrading Laptop CPU (Experts concerned)

[ViVelDOP]

Hi guys.

I'm just willing to upgrade my laptop CPU (I5-4200M, 2 cores and 2.5Ghz) to another one (I7-4700QM, 4 cores and 2.4 Ghz). I have a 10W TDP difference (37W to 47W) but have a good colling system, but I'm wondering if 1st: my laptop won't overheat too much, 2nd: my motherboard would (at software level, nt physical) run it.

My laptop is a V3-772G, motherboard is VA70HW.

PS: the CPU I'll use is a I7-4700QM, not a 4702MQ or a 4712MQ

You cannot upgrade to that CPU.

Why so, if that is not demanding too much ? What are your arguments ? Why exactly I cannot ?

M to QM is not possible.

But the same MB accepts I5-4200M, I7-4702MQ or I7-4712MQ, since the different models designed by ACER are equipped with one of them. Some users also replaced their CPU by one of these.
The reason I'm asking is to know if there will be a problem with the BIOS, and I don't think M or QM are the problem, for the reasons I explained

Try it then...

That would be a complete waste of $$$; changing those CPUs will do nothing.

If you want a better Laptop, buy a better laptop. You'll still have a crap-tastic laptop even after changing the CPU in the manner of which you are looking to do. It still will run like crap, play games like crap... you get the idea.

Actually, I've got a GTX 780M on this laptop, the CPU is just struggling sometimes. So I think your post is pointless since it's not my case.
Plus, I'm paying 70€ for this CPU, so between that and getting a new laptop with the same or higher specs, my choice is done.
And of course, changing CPUs will change a lot of things, and I think that if you did some researches, you would not have posted that.

the 780m is as fast as the gtx 950 it is not as fast as you think it is

honestly just get a new laptop if you want to game on it

Hi,i have seen your discussion and i know you wanted an I7-4700MQ but i see you have an I7-4702MQ.May i ask why? Was 47W a problem? Were there other reasons? Many thanks.

it's a used mobile cpu you plan on buying , i wonder...... could it be fried ?
i wonder how good your battery is (it's long in the tooth)
780m , thats an old laptop ,
i wonder if it's worth putting money into .
personally i dont think so , it's fairly old hardware that's well past it's prime,

[SenMithrarin85]

Even a 980m will struggle now. There is no point in buying a gaming laptop unless you *must* have portability. In this case, it only makes sense to get the most powerful available at that time otherwise its gaming performance will last all of a year at the most. This is costly.

A 4700qm is around the cpu my laptop had which was a 4710mq and it couldn't touch cpu demanding games. I often had to lock my fps to 30 because I wanted it stable.

dont think it really matters now , i just noticed the tread is like over a year old

[ViVelDOP]

Maybe the thread is a year old but I'm ain't dead yet ! And yeah, I finally upgraded to an I7-4702MQ, rather than than the 4700MQ, not because of the TDP, but because I tried the last one, had problems on it (not booting) and I finally took the 4702MQ !
Unfortunately, almost no one tried it, or at least published it online, so I had to try it all by myself !

Good to know u r alive . Is it possible that your 4700mq was defective? Have u seen it working in other circumstances?

There's really no point. This is a huge amount of work in order to upgrade a system with zero performance relevance in 2018.

Even if you could graft an 8700K onto that board, your laptop would still underperform. Badly. The problem is the GPU, which is completely obsolete. And there's nothing you can do about that.
