Overclock ! Intel Q5550

Hello,

I would like to overclock my Intel Q5550 processor to around 3.2 to 3.5 GHz. I’ve already tried but it crashes after about 30 minutes.

Motherboard: https://www.asus.com/fr/Motherboards/P5Q_PRO/
Processor: https://ark.intel.com/content/www/us/en/ark/products/33924/intel-core-2-quad-processor-q9550-12m-cache-2-83-ghz-1333-mhz-fsb.html
Power supply: https://www.ldlc.com/fiche/PB00110660.html?gclid=CKCDxaC-mdICFXYo0wodBDoKWg
RAM: 4 Go DDR2

I based myself on this tutorial: https://noobs-veterans.ogameteam.com/t57-tuto-pour-overclocking-P5Q.htm
I lowered it to around 3.2 GHz, maybe I didn’t adjust the right things ^^
My CPU does not exceed 60°C.

Thanks

I also want to note that I’m aware of the risks of overclocking.

OCCT and CPU-Z are already downloaded.

    Hello,

    if your PC crashes, it could be a problem with not enough VCore voltage,
    and also a thermal issue: what fan cooler do you have ?

    attention: too high a VCore is destructive!

    I advise you to read this article I wrote on CPU overclocking in socket 775, feel free to ask me questions:

    See you later

      Hello, Is this an already existing stock cooler (i.e., came with the original setup)? The processor doesn’t get very hot; I think it’s enough for an overclock to 3.2–3.5 GHz. I’ll try tomorrow. Thanks again.

        If it's the original Intel stock cooler, see photo, it is insufficient for overclocking.

        keep me posted

      No, this isn’t the one, I’ll take photos of it tomorrow.

    Hello,

    here is the cooling fan (ventirad)

      Hello, personally I wouldn’t recommend overclocking with this cooler, never seen that before, it looks like a custom build. ^^
      then as Marcmarais said, try increasing the Vcore and monitor your temps.
      If it crashes still no matter the Vcore, that means the CPU can’t be stable above that frequency (in my opinion, after that I don’t know the OC well for this type of socket and CPU).

      I share RobS06's opinion, this cooler is very low quality
      for overclocking you need a better cooler, with a 120mm fan

      and then it's not because a CPU reaches 3.6 GHz that you will be able to get the same:
      each CPU is different on the OC side

    ah ^^ possible, quel est le v core exactement rien d'appeler par ce nom dans mon bios voici les seuls choses que je modifie a part les freq.
    pour le coup la c 'etait pour oc a 3.6 ghz sur le même proc et la même carte mère
    CPU Voltage : Set what you need, this will range from 1.20-1.4v
    CPU Voltage: définir ce que vous avez besoin, ce sera comprise entre 1.20-1.4V
    CPU GTL Reference: Auto
    CPU GTL Reference: Auto
    CPU PLL Voltage : 1.50
    CPU Voltage PLL: 1,50
    FSB Termination Voltage: 1.30
    Tension de fin de FSB: 1,30
    DRAM Voltage : 2.1
    Tension DRAM: 2,1
    NB Voltage : 1.2-1.5v (quads are alot harder than dual cores to clock, the NB voltage helps with the higher FSB on quad)
    NB Voltage: 1.2-1.5V (quads sont beaucoup plus difficiles que les dual core à l'horloge, la tension NB aide avec le FSB plus élevé en quad)

      Vcore is the voltage of your CPU, so in this case "CPU Voltage" if you increase your CPU frequency you’ll eventually need to raise its voltage so it can run faster, otherwise the PC will crash.
      except when you reach your CPU’s limit, then no matter the voltage applied the PC will crash.
      Also, if you see guides with this processor and this motherboard reaching 3.6 GHz, that must be feasible.
      However, any voltage increase implies a higher temperature and I doubt that with this cooler it will hold, so watch your temperatures closely.
      Can you see that with you? What are you using to test your CPU?

    I’m OC at almost 3.2 GHz, I’m testing with OCCT
    Not yet crashed

      Okay, and what's your peak temperature?

      ok, and the CPU voltage, what did you set it to?
      according to this site, it must not exceed 1.36 V:

      55 degrees is fine, it surprises me even with this stock cooler ^^ but well, good for me, note that it must not exceed 75 degrees max 80, beyond that it could damage the CPU irreversibly

    Bad news, PC froze with a blue screen and a message telling me to call the seller ^^ 1.3. I’m thinking of giving up on the case, I’m overclocking to avoid changing the setup, if it’s to burn it out ^^ might as well not bother

      Weird blue screen... lower your Vcore a bit and/or your CPU frequency since if temperatures haven’t exceeded the limits you shouldn’t have fried anything. If the problem persists, reset the BIOS to default settings or do a Clear MSDOS.

      Thank you again for your help! I’ll look into it when I have nothing left to lose,
