    Hello everyone,

    The default (stock) laptop comes with an Intel Core 2 Duo P8400 running 25 watts.

    I'm planning to replace it with Intel Core 2 Duo T9600 running 35 watts.

    I leave my game running 24/7 and not killing the laptop at all, will the additional 10 watts toast my motherboard or its basically harmless? I'm not really good with hardwares, specially when this voltages and wattages question pops out. Should I just stick with the Intel's P series that's using 25 watts?

    Can I also put AMD Dual Core processor on it?

    thanks!!

    * For people who'd say laptop is not upgradeable, please don't post. you're wasting my time.

    some more info that might be useful to you:
    *I read somewhere that Gateway is using a customized Motherboard
    *P-7805u got PGA478 Socket
    *P-7805u got PM45 chipset

    You cannot put an AMD processor in, but the T7600 should be fine.

    Why the T7600 though? It's a slower FSB, 65nm processor that runs hotter and only gives you 100 MHz increase in clock speed and 1 MB of extra L2 cache...

    The T9xxx series would be a better upgrade. Even if you already have the T7600, you should leave your P8400 in there.

    Edit: Oops, dtwn's right, I was thinking of the T7700 which is socket P.

    Won't work.
    1) T7600 = Socket M
    2) P8400 = Socket P

    Reasons not to do it
    1) T7600 slower than P8400.

    The additional 10 watts shouldn't toast the system at all - the P-7805u is a beefy system with a strong cooling system.
    Go check out the Gateway subforum here on NBR to see what other people have done.

    I suggest that you don't. If you want a worthwhile upgrade, I would suggest eitherb the P9700 or the T9600. The T9600 seems to be the best "bang for your buck" at the moment.

    You might want to check if your chipset and BIOS support the Q9000. That is an extremely good upgrade.

    oh sorry i meant T9600 its a typo. anyway that would really be awesome if i can update it. whats d downfall anyway with the 35 watts compared to my 25 watts? aside from d battery life.

    also do you guys know a good source where to buy these processor aside from ebay?

    Increased heat to some extent, but probably not very much.


    Newegg, Zipzoomfly, Fry's, Provantage and the like.

    Ebay's usually got the best prices though.

    I got my T9600 from eBay and it works perfectly well. Just remember to get OEM and not ES/QS.

    What jenesuispasbavard said - avoid ES/QS like the plague.
    I got my T8300 off eBay and it's been working fantastically.
    ...which reminds me, it's time to refresh the AS5 on this thing.

    What's the difference between OEM and EQ/ES?

    Not much of a difference. I would rather have $100 + ES than an OEM.

    The ES might not have it's temp sensor enabled. It might need a higher voltage to be stable. It's stolen from intel.
    I don't know what else is different.

    Also QS = ES.
    No difference there. It's just a way for ebay people to try to get you to buy their ES CPU.

    I would try to get OEM, but if ES is so much cheaper then I would get ES (unless it has no temp sensor).

    Yes it is.

    The only thing is you have to make sure that it is the latest ES version of the chip.
    Early ES versions are bad.

    Make sure it has a temp sensor.

    interesting. lemme ask that to the seller, hopefully it knows. would Real Temp app be able to read it if it has the temp sensor?

    are they really that as good as the intel OEM one, like performance of 6MB L2 cache and all that?

    Yes, they should be exactly the same.

    Some are even better. Some have an unlocked multi (havn't seen that for a while though, not recently anyway). Some have more cache. e.g. I have seen a T7100 with 4mb cache, T8300 with 6mb cache.

    They are test versions so you never know what you will get.

    You should just ask the seller for a CPUz screenshot.

    T9600 is a great choice but u'll loose some battery life... but it's allright... with undervolting , the loss will be minimal.. also u should nver buy ES... they might not work and anyways they are stolen in a way... they're intel property and cannot be sold like the T9600... OEM or boxed..
