Upgrading a mobile CPU

[farmdve]

Several months ago I purchased a Lenovo Legion Y530, I chose this one based on performance and size and finally budget, so an i7 8300H and GTX 1050. The one thing I definitely wished I could get was at least the 8750H. Anyway, I was thinking of a future project, because I am content with performance for now, where I upgrade this CPU to the six core 8750H. Now, I did some research and the Y530 comes in many flavors, 8750H, GTX 1050 TI, 1060 and so forth. I am going on a limb here and assuming that the motherboard in all flavors is largely the same. When it comes to the CPU power delivery, the topology should be the same as the 8750H and 8350H have the same TDP spec, though the 8750H should naturally draw more power. These CPUs are all FCBGA1440, and while I cannot verify, they must be pin-compatible just by going by the pin count.

 

And if we cross our fingers and hope that Lenovo compiled their BIOSes for all flavors and just distribute the same(or nearly the same) BIOS binary to all flavors, then is it not reasonable to assume that it should detect the newer CPU? Again, assuming that the old one was removed without damaging nearby components and the new CPU soldered correctly.

 

I know I am talking about a laptop, but it is specific to CPUs and Motherboards, so I posted this here. Anyway, what do you guys think?

Most mobile CPUs are soldered directly to the motherboard. I can’t sleak to your laptop specifically, but I’m pretty sure all BGA pin arrays are

One: laptop cpus are soldered, good luck with that

Two: you really have to cross your fingers for the bios

Three: I wouldn't trust a different model with perhaps a different mobo to handle a heavy i7. Ever seen a 2700x on a a320 mobo? Then you won't think about this ever again

usually the only way to upgrade a laptop is to change the whole board and the cooling basically gut it and install the other set it comes with its set was packages for a reason usually .

Yes, I am aware they are soldered, but they can be unsoldered as well. I am no Louis Rossman though, so can't say I've ever unsoldered a big chip like that before. As for the BIOS I am planning on doing some disassembly to see if it has any references to the 8750H.

Not worth your time, money, or risk lol just sell it and buy a better laptop. Your net cost will be similar and the time put in will be siginificantly lower
