CPU Upgrade???

i was wondering if i could change my cpu on my lg r405-a..
im running a T5450 Socket P

and i was thinking of upgrading it to another more powerful Socket P processor
the thing is i dont know if its possible..
like is the cpu fixed so it cant be removed..??

 

you can indeed upgrade it. I don't know how o remove it on your particular model but it can be removed. It will void any warranty you might have on it though. As a socket p your options are the "santa rosa" processors (7100/7300/7500 are good choices) and you might be able to get the penryn processors (8x00/9x00) but this might require a BIOS update or your computer model can't support it at all. Ask around a little more and see what people say.

EDIT: T7100 (1.8ghz) from newegg - http://www.newegg.com/Product/Product.aspx?Item=N82E16819111319

This will work in your computer due to it being a socket p/santa rosa just like your current processor

T8100 (2.1ghz) from newegg - http://www.newegg.com/Product/Product.aspx?Item=N82E16819111003

This *might* work in your computer. It is also socket p but it is a penryn type processor. This will be faster than what you have now while also reducing battery consumption. Both are the same price (215$) and there are more options available to you. Hope this helps, happy upgrading!

 

thanks alot for replying
yeah i know it will void warranty since ill need to open it up the whole thing..

also i was wondering is there any difference between merom and penryn apart merom are 65nm and penryn 45nm
i mean if for example a 2ghz merom vs a 2ghz penryn
is there any difference?

EDIT
i dont think ill get the t7100.. my [email protected] the [email protected].. .1ghz for 200bucks??! nnahh.. haha

also how can i know the power thing?
i check on newegg they got
a penryn t8300 on the title it says 35W
and a merom t7500 it says 35W too..

 

The 35w rating is what is required for the processor to run, or at least *reocmmended*. You can undervolt your processor to decrease power useage but I wouldn't try it unless you really really really want a few more minutes out of a battery.

The main difference between the merom and penryn is the size decrease which provides a few benefits: 1) cooler operating temperature 2) decreased power consumption while in use 3) with those two combined, these chips could theoretically be overclocked much easier than a merom chip (I don't recommend overclocking unless you are a serious power user)

If you computer has a santa rosa now, it can power a penryn. Again, I don't know too much about if your laptop will support it or not but this is more of a BIOS issue than a true hardware issue. I would most definitely recommend getting a penryn if you can use it. Dollar for dollar they are just plain better. But don't be so quick to count out the 7x00 chips. The 7100 has a higher clock speed as well as a larger cache (4mb vs. 2mb) so expect some better multitasking from it. But if it isn't worth it to you, then that's your decision. Personally I wouldn't upgrade either to just a 7100, I would push more towards a 7500 myself.

 

yeah on lg canada website it says
centrino duo 2 based on santa rosa platform

sorry for the big pic

anyway so 'IF' my bios is able to run penryn
i wont have any other problem right??
i mean the power and blablabla

 

Yup, if the BIOS supports it, it will run just fine.
