Overclocking e7200 frustration

i really cant overclock my e7200 core 2 duo..
my motherboard is gigabyte ep31-ds3l..
i tried every setting that i see in this forum but i always getting core temps exceeding 75 degrees celsius..
this is my first time overclocking and i have a very few knowledge about overclocking..
please help, i really really want to learn how to overclock..
i want to like you guys..
thanks..

  1. Well first off do you have an aftermarket cooler? Also what FSB and vcore have you tried?
  2. This should be your first stop.

    It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

    Go through the guides. Then go into the BIOS and change the System Memory Multiplier from AUTO to 2.00, 2.00A, or 2.00B - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in step with it. At a stock FSB of 266 MHz, your memory clock should be at 533 MHz.
    For a serious overclock, you will need better than stock cooling. Here are three under $50 heatsinks that are pretty popular:

    They all require a somewhat different approach to applying thermal compound.

    And they are pretty large, so they might not fit inside your case.
    Download CPU-Z to check your FSB:RAM ratio.
  3. thank you very much jsc
    i will take all you said as soon as i get a new heatsink for my cpu..
    but how about the voltages settings?
    and what is memory frequency do? and why do i have to set it twice the FSB?
    i really want to know everything about overclocking..
    sorry for being a nuisance but i cant understand everything in CPU-Z..

    i'm an asian and i live in a tropical country where we always have hotter climate which is i know affect my computer temperature..

    my english is not that good but i hope you could still help me..
  4. OK. Definition time (attention purists, I'm talking about DDR2 and I'm simplifying a little :)):
    Core2 CPU's use a frontside bus (FSB). The FSB is a thing with two main characteristics: speed which is usually defined in MHz and width which in the Core2's is 64 bits wide. We are concerned with the speed.

    Using the Q6600 as an example, the FSB frequency is 266 MHz. The matching DDR2 memory clock for that frequency is 533 MHz (266 X 2). DDR2 memory transfers two chunks of data for each bus cycle, hence double the frequency. So, to run 1:1 at an FSB of 266 MHz, we need DDR2-533 RAM. What CPUZ does is a little confusing. It will tell you that the memory frequency is 266 MHz for a 1:1 ratio.

    The FSB clock is 1066 MHz (266 X 4). The bus is "quad pumped". It transfers 4 chunks of data into and out of the CPU each cycle. So each FSB cycle generates 4 FSB clocks.

    Now, if you increase the FSB frequency to 333 MHz, the corresponding memory clock is 667 MHz and the FSB clock is 1333 MHz.

    I always run my memory at 1:1. That is the FSB freq to mem freq ratio of one to one. That means that the memclock is twice the FSB freq. It's a little confusing. Running memory slower costs performance. Running memory faster does not give you much if any real world performance increase and it can lead to higher instability.

    Voltages - Intel's recommended maximum CPU voltage for the 45 nm CPU's such as the E7200 is 1.3625 volts. At that voltage, if the core temperatures are kept below 74 C, no damage affecting the life of the CPU will occur. Intel's absolute max voltage is 1.45 volts. At that point, long term damage will start to occur.

    My Gigabyte motherboards have thermal alarms. I set them to 70 C. So I recommend a "do not exceed" area of 1.3625 volts and 70 C.

    Higher ambient (that is a fancy word for the air around the computer) temperatures make overclocking difficult.

    So what you what to do is push the core speeds upward by increasing the FSB frequency while staying under 70 C and 1.3625 volts. We generally use a program call Prime95 to put a 100% load on the CPU to check the temperature under load.
  5. wow i barely understand all of that, but luckily i did :)

    but one last thing,
    what is the FSB clock? is that the cpu core speed?
    and another thing, when you multiply 266 to 4 where did you get the 4? is that the multiplier?

    thank you so much for everything you've help me a lot..
