Overclocking an E8600 CPU

Hello, I've got a EVGA NF68 680i chipset motherboard with all the latest updates.

I recently installed a E8600 chip, and tried to overclock it, (there are those who say that you can easily set the core clock to 4.0 GHZ). When I did I got instantaneous blue screen of death.

I tried also tweaking the voltage up a bit and then doing it, same thing.

I also noticed that the chip runs about 42-48 degrees which is a bit higher than some I'm hearing about (Stock intel Heat sink..).

Any thoughts on this situation?

  1. Woah Bud!


    Easy Does It, A little At a Time...

    Also I wouldn't use Stock Cooling (They're made to a budget and are usually pretty Bad)

    Look Here For a new 1

    Choose 1 in the Top 8 And start saving...

    Good Luck And welcome To Toms Hardware:D

    (Just A heads Up Use the acronym BSOD just to save Time... Blue screen of death isn't really necisary)
  2. After the basic, generic guide, look for a 680i OC guide. The way the BIOS, particularly the memory, works is different from the other boards.

    Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the Memory Clock (or whatever your BIOS calls it) to either Linked or Unlinked with manual memory settings to twice the FSB. . At an FSB frequency of 333 MHz FSB clock of 1333 MHz), your memory clock should be at 667 MHz. Set memory voltage to the manufacturer's recommended value.

    Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.

    Now you can start working with the FSB frequency.

    I could push my old eVGA 680i a little past 440 MHz. But the MCP temp was over 80 C.

    The heatsinks for the 45 nm CPU's are just adequate for the stock speed. You need better cooling. For a serious overclock, you will need better than stock cooling. Here are three under $50 heatsinks that are pretty popular:
    COOLER MASTER Hyper 212 Plus
    Xigmatec Dark Knight

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

    I have two Xig DK's (bought before the other two reached the market) that work pretty well on two of my OC'd Core2 systems.
    And they are pretty large, so they might not fit inside your case.
  3. Thanks Fisshy! appreciate that a lot....I know the acronym, but I thought I'd be "fresh" by not using it..! Good day to you!
  4. Thanks also to JSC, really appreciate your information. I think that Fisshy summed it up nicely..."WHOA"! I'll gradually add a better cooler to the chip, and then go into the MOBO/bIOS and explore some of the things suggested here.

    Appreciate your help and time! Obviously, overclocking is new to me....
  5. Dot mention it. its all good, just take your time, attention to detail goes a long way
