    my new mobo is " supporting CPU up to 77W" according to the official website 's specification.
    however, my CPU 's TDP is 95W according to intel official specification.

    Now they are working correctly, being able to login windows, browsing the web, downloading things.

    However, later on, would there be any heat issue or damaging other components/hardware/chips....

    Anything I can do to avoid replacing a new board because the board is a new purchase just a few days. And I do not want to replace the CPU because it's i5 and still perfect.

    i don't think u should have any problems during light/general use because the 95W TDP is only when your CPU is under full load.

    Undervolt your processor and the max power draw will decrease :cool:

    Kenny what processor/motherboard you have...

    You can undervolt the processor in XTU.. You basically reduce the core voltage..

    But 1st give us specs :)

    Hi.
    PSU: Antec Neo Eco II 550W
    Mobo: Asus H61M-K
    CPU: Intel i5 2400 3.1Ghz
    RAM: kingston ddr3, this is all I know.
    SSD: Transcend 128GB, any detailed needed i ll check the box later

    I know overclocking the CPU will probably do harm or shorten its life that's why I never and I don't really need to overclock my CPU.

    Would undervolt also shorten the lifespan of anything?

    Nope, undervolting should increase the lifespan by putting less stress on the components and by decreasing heat.

    No harm in undervolt your processor. Only gains. Try Xtu or look into the manual for your motherboard and see how you can manage power settings in bios :)

    Overvolting, on the other hand, can shorten the CPU's life. Sometimes very quickly ;).

    Agreed! UV is good and can actually extend the life of your processor!!
    Overvolting on the other hand is a bad bad idea!

    I would just look at your UEFI and lower the clock speed that is easier then UV especially if your board is custom board. Less headache to worry about lower Ghz lower heat output.
    I just use my UEFI bios to lower the clock speed and that is a safer way to go especially if you plan to tweak this will get you on the learning curve start.

    OK StormJumper and other

    Firstly, I would like to know

    is Undervolt = Underclock?
    is Overvolt = Overclock?

    Are they just identically the same thing in just different English vocabulary items


    Secondly, What is UEFI ?

    After undervolt / underclock, would it cause less heat / power dissipated to the system and VRMs to reduce the likelihood of damaging the motherboard and the CPU?

    Since I have to mention again ,my concern is I am now having a CPU with TDP rated higher than the motherboard can support. This is something I seriously worried. I am not an enthusiast, this is the new board recommended by the salesman and I got cheated. But it works now, I just don't want to spend another hundreds of bucks in the next few months for the new motherboard and going through all the headache about taking out the CPU and power cables which is something I am seriously NOT good at doing

    Under/Overvolting is only one way to under/overclock. For overclocking, there's also modifying the base clock, multiplier, and other methods.

    UEFI is the replacement for the older BIOS standard. Basically, the the thing that loads before your OS.

    As for the TDP, note that the stated TDP is the *maximum* wattage your CPU can use at a given moment if you have it at 100% load for a sustained time. For normal usage, your CPU won't ever reach the stated TDP rating. Undervolting will lower the maximum TDP your CPU can reach by basically throttling its performance so that it'd impossible to reach the advertised TDP.

    @kenny1999 overvolting/undervolting = increasing/decreasing voltage, overclocking/undercloking = increasing/decreasing clock. Higher voltage means higher overclocking potential (to a point) but also means more heat is generated even at the same frequency. Lower voltage means less heat, obviously, but doesn't mean less frequency. It can cause instability, though - if you lower it too much for your exact CPU/GPU/whatever.

    @Jarhead on the contrary, undervolting allows higher CPU frequencies by reducing TDP throttling.

    Nope. Undervolting and overvolting is changing the voltage, underclocking and overclocking is changing the clock speed (bus speed x multiplier). UEFI is a newer type of BIOS/firmware. Yes, undervolting and underclocking would reduce temps to VRM and reduce likelyhood of damaging mobo/CPU.

    And I would of course undervolt instead of decrease the performance aka lower the clockspeed :cool:

    In this forum we always increase speed instead of lowering lol

    post any thread with the word "fry" or "frying" and it attracts Mr. Papusan like a magnet. I always see him at barbecue parties :rolleyes: :eek:

    So now, what's my step of trying to undervolt to protect my CPU or other hardware?

    firstly
    1. Confirming if my BIOS is UEFI?
    and secodly,
    2. Doing the undervolt inside UEFI?

    Undervolting with XTU should lower your CPU temps by about 3-5C.
