Hello,

Im planing to upgrade my laptop cpu.
my laptop is hp elitebook 8770w , and i have list of cpu form hp that is usable for my laptop .
this link.
https://support.hp.com/lv-en/document/c03436782
it showed that it is possible to use this one Intel Core i7-3920XM
and it is 55 w but on other hp document it say that max cpu is 45 w
this link here
http://h10032.www1.hp.com/ctg/Manual/c03579708
and also i found other site where are all cpu that fit for this socket
link here
http://www.cpu-world.com/Sockets/Socket G2 (rPGA988B).html
so can you please help me and tell me if these cpu-s are all suitable for my laptop from this lastt link because i need to know is it possible 45 and 55 w .
i intend to upgrade on intel core i7-3940xm 55w

right now i have cpu with 45 w .
thank you

Did you look at the following site in this link?

yes i did , thats why im asking on this site also its is writen that i7-3920xm is possible and it is 55 w
so it should be aslo able for this one i7 -3940xm it is also 55w and same socket , so i want to see if some one has more expirience on this to tell me will it be a problem for laptop and heating or something else, i checked almost every site but i need some one who actualy did something like this , so he could tell me what is the result
 
HP Specs say its fitted with those CPU's so the Bios would recognize the upgrade
Just use a good Tim and give the entire cooling system a deep clean
you might in the end need to undervolt the cpu to maintain a decent Temperature
but you won't know for sure till you perform the upgrade
while you have it apart max out the mem (don't know how much you have atm but more mem is allways worth it)
 
What CPU do you have in there now? Just because a CPU consumes more power that does not mean you will see any performance gains. But it sure means you will have greater cooling needs (an inherent problem with laptops) and it means you will have shorter battery run times.

I see this notebook has been on the market for at least 7 years. How old is yours? Note the average life expectancy of a notebook is 2 - 4 years. A new CPU is an expensive upgrade to put into an aging notebook - especially if the upgrade provides little, if any "noticeable" performance gains. And note adding a more power hungry device will put greater demand on the already aging voltage regulator and divider circuits. Adding additional stress to aging electronics may be inviting trouble.

How much RAM do you have? Typically, depending on your starting point, increasing the RAM provides the most bang for your money. This is especially true if the current graphics solution is stealing... err... "sharing" some of your precious system RAM. More RAM means more resources for the CPU, graphics, Windows and your programs to operate in - a very good thing. And more RAM typically means the CPU and your OS will not need to cache as much high priority data in to the Page File located on the slow (compared to RAM) disk drive.

And speaking of drives, another possible upgrade I would consider before the CPU is replacing the hard drive with an SSD. Not only will the SSD increase over all performance, to include significant gains in disk related tasks (like Page File reads and writes), but SSDs consume "less" power than hard drives and they generate "less" heat - both significant advantages when it comes to laptops.

Last, should (when!) that laptop does dies, you can remove the SSD and keep using it in another computer or external enclosure. The odds are extremely slim (and I am being generous there) you would be able to carry the CPU over. It most likely will not be compatible with a newer motherboard.

In other words, I don't think upgrading the CPU is a good idea.

Right now i have dual core i5 -3360 and some says that might also be a problem for motherboard chipset ,is it possible to use on this motherboard form dualcore i5 to quadcore i7 but it should be possible because it is writen in official hp document wich cpu is possible for this laptop.
i have 8 gb ram but i will increase that as much as i need also, and i already have ssd disc,
this all wont be to much expencive for me but still i dont want to buy it all and than wont work out,
 
If me, I might look into increasing the RAM. Beyond that, I would not worry about the CPU on such an old platform.
