C2D E4500 Overclocking?

By Yad

  1. Hello.

    I am new to the forums although i have visited Techspot daily for a year or so.
    I got an Core2Duo E4500 since like 3 years now and i am looking it is failing in latest games and keeping my Radeon 5770 behind.
    So i wanted to overclock it a little bit since i am deciding to get a new pc by the end of the year probably.

    I tried overclocking it once to 2.8ghz but pc restarted once in a while so i reseted it to defaults.
    I got Stock Cooling although the Fan speed most of the time is 4400 rpm and Cpu temp is low usually,atm is 11 Degrees.

    Can you help me out with what speed,voltage etc to set?
    If a screen of cpu settings in BIOS is needed i can show it.

    My pc specs are these.

    you wont reach 2.8Ghz without changing the Vcore which i don't recommend doing with Stock Cooling. the highest i see you going is 2.5-2.6Ghz. try these settings

    Frequency/Voltage Control
    -CPU Host Clock Control "Enabled"
    -CPU Host Frequency "228"

    after this go in to windows and try to play a game or just run Prime95 for about an hour or two. if you want to make sure its 100% stable run Prime95 over night

    We can't say what to do with your processor, just bump up the FSB incrementally and test stability until you hit the limit of that e4500.
    Your on a stock cooler right?

    I would the the majority of e4500 would, 2.8 isn't very high...? A lot of those core 2 duos can go pretty high.

    I personally think you could make 2.8 ghz just fine with stock, as long as your not using it for more than 4+ hours at a time on 100%.

    Thanks for the replies guys.
    I will test it out and see how it goes.

    I actually don't stress the pc much to 100% for hours,rarely when i convert movies or animes with megui,well during games as well i think it goes 100% as it can barely handle them.
    I will check it out at 2.5 ghz for now and see it's stability.

    Megui will stress it 100% with multicore enabled...but games I find usually don't for me...thats with a stock e4600, IDK I havn't been playing any recent games.

    Good luck, theres not much else to say, with the stock you can bump a tiny bit of voltage if you need.

    Are those settings ok? No need to change those other settings like voltage?
    I played Bioshock 2 for now like 30 mins or so and no restart so far.
    Will test now on Megui.

    i think if u bump the volts up just a little then try for 2.8 u will get it just make sure u have good airflow in the case.

    I have tried 2.8 Ghz and changed DIMM,FSB,CPU Voltage to +0.1 and Pc was not stable at all,restarted once in 5-10 mins.
    I didn't change the CPU Vcore though.

    Now with 2.5Ghz the pc is running fine,converted some episode with Megui for like 30-40 mins and no restart.

    Although i dunno whats wrong with my cpu fan,sometimes when i turn on my pc it runs at 4400 rpm ,sometimes or when i restart pc it goes to 350 rpm :s

    the fan usually wont run at full speed when your pc is just starting up. 2.5ghz is close to the end of your oc potential on stock fan. Going +.1 in voltage isnt going to help you much at all. You'd have to use a little more than that but watch your temps closely. If I were you I'd spend 25 dollars on a decent cooler. Especially since it seems like your knowledge is limited on the subject.

    The fan speed is based on the temp...at higher temps, will turn to 100%

    @supersmashbrada I don't plan on wasting more money on this pc,and beside in my country is difficult to find a decent cooler with reasonable price.
    I know i am a newbie in overclocking field so atm i am leaving it to 2.5 Ghz for a while.

    As for the fan speed i don't think it's related to temp,i have messed with the settings in bios,automatic fan control and manual but still seems the same.

    Anyway thank you so much for the help guys :)
