    Smile Upgrade of Lenovo Y450 Core 2 duo T6600 processor.


    Hi.I am new to this forum and this is my first post. Please bear with me if there is something wrong.
    I brought lenovo Y450 laptop(Core 2 Duo T6600, 2.2Ghz) 3 years ago and its working well. I'm glad i brought it.
    Now i have decided to upgrade my processor. I do lot of animations and videos so processor performance really matters a lot to me.
    Lenovo Y450 uses Intel® GM45 Express Chipset. I went to intel website and got some information about compatible processors.

    Can i replace my processor with Intel® Core™2 Quad Processor Q9100 or Intel® Core™2 Duo Processor T9600. ? (Priority given from the first one.) The reason i prefer first one is it has quad cores. The issue here is can my latop withstand heat produced by Quad core processor. I use a good cooling pad so i don't think it is a issue. What is your suggestion ?
    Please reply. Thanks in advance.

    The first thing to check is that the software you're using is already capable of using both the cores you have. If it isn't, then having 4 cores will do you no good at all.

    The problem I see with upgrading only one component is that all of a sudden, the rest of the components are sub-optimal. Sure you've got a faster processor, but if the memory can't keep up, you've wasted your investment.

    T6600 vs Q9100
    Max TDP 45 W
    35W to 45W is a pretty big jump for a laptop. Yes you might be able to just keep it cool enough, but are you reducing the life of the rest of the system with the extra heat stress?

    The Q9100
    VID Voltage Range 1.050V-1.175V
    Your current processor
    VID Voltage Range 1.00V-1.250V
    Can the power supply meet this much narrower voltage spec AND supply the extra 10W to power it?
    If your current power supply is only spec'ed to allow 35W to the processor then pulling 45W out of it will almost certainly drive the voltage way out of tolerance.

    I would cost this alternative plan.
    1. The resale cost of your current laptop.
    2. The purchase cost of a new laptop with your desired performance spec.
    As well as getting the processor of your choice (not just the one or two you're looking at), you'll also be getting faster memory, probably more memory, better graphics, possibly a bigger screen, faster hard disk with more capacity, a new battery.
    How much more is that, compared to just buying a processor (and not knowing for sure if it will work).

    Unless you can find some definitive statement from lenovo tech support, or on their website that it will work, I think it's probably best left alone.
    You might get more knowledgeable advice here -> http://www.tomshardware.com/ or here -> https://www.overclockers.com/
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper

    Thanks for your good suggestion sir. What you have told is absolutely true and i'll accept it.
    Sir i too thought of buying a new laptop. But resale value of my old laptop is too less around 150$(By the way i am from India). My laptop is in good condition and i brought it for 750$ 2.5 years ago. So, is it worth selling my laptop for 150$? Please reply.
    It may be little difficult to buy a new laptop cause i am a student. How about upgrading to Intel Core 2 Duo Processor T9900 ? Max TDP is 35W which is same as my processor and VID Voltage Range is 1.050V-1.2125V. Is it feasible?
    After all T9900 doesn't make any sense except that it works at 3Ghz.

    What you look at is
    $750 (the new one)
    -$150 (the old one)
    -$100 (the cost of the new processor by itself - just a guess, you've already looked)

    The minimum upgrade cost is $100 - the price of a new processor.
    The maximum upgrade cost is $600 - the price of a new laptop, after selling your old one.

    Now you have to figure out what that $500 difference is worth to you.

    On one hand, $500 is an excellent new machine and peace of mind.

    On the other hand, $500 is all you have left to spend on a new machine because your old machine and new processor really didn't like each other.

    Or you have $500 in your hand and your existing laptop zipping along with it's new processor.

    I can't tell you which to go for - you need to research the evidence and make your own call.

    Have you checked out tomshardware or overclockers yet?

    The other thing to do is take your laptop to various computer repair / upgrade places and ask them to QUOTE you for doing a processor upgrade. If everyone gives you a low quote, then it would seem to be an easy thing to do. If they all refuse, or give very high quotes, then you can conclude that it is either very difficult, has a high risk, or is just not possible.

    Needless to say, if you do decide to go for it, make very sure you have good (ie readable) backups of all your work.

    > I do lot of animations and videos so processor performance really matters a lot to me.
    What options do you have for working in "preview" mode (wireframe, solid fill, no raytracing or whatever else eats CPU time)?
    Save the final render for when you're at lunch (or asleep)
    Exploring different ways of using the tools you have (or finding better tools) to make best use of the hardware you have.

    Thanks a lot sir. This helped me a lot. I'll probably go for a new laptop. Thank you.
