    :rolleyes: Hi

    First time installing a CPU to a new motherboard.

    It is socket 775.

    The processor is Intel Core2 Duo.

    I am confused over the black rubber that surrounds the CPU.

    Here's why;

    My motherboard book says "hold the CPU at the black edges and insert"

    Their picture looks like the CPU with rubber bottom is being inserted into the socket.

    BUT the Intel booklet has only drawings - and one of the drawings depict the
    black rubber backing to be separated from the sliver processor.

    Overclock.com who I brought the Core2 from said I didn't need any thermal paste
    as it's built in - is the paste under the black rubber bit.

    The board is ASRock 4Core Dual - SATA2

    Bit confused.

    Many thanks, Stephen

    you need to confirm,

    but it could be whats called "Phase change", you peal it off leaving a termal compound.

    you only get one hit and fitting it, so practice a few times

    I've just blown a CPU by not installing correctly

    pls double check though

    I wouldn't expect that any rubber would be in contact with the processor when it was running. It gets too hot.

    Got it sorted - it was a black protective cover . . . . . how was I supposed to know.


    Thanks.

    Don't worry, we were waiting to jump in (in case of emergency break glass) and set you on the straight if needed.

    I'm a bit confused about whether you are installing the cpu or the thermal sink as I've never seen thermal paste on the cpu prior to installation before but its certainly possible I guess, but as long as its there, extremely thinly applied and between the sink and the top of the processor that's all that matters.

    That's what I thought since it was rubber. But better to ask. They don't give those things away, do they? (If you know of somewhere, let me know :D).

    If you purchased a boxed processor it should have come with a cooler. Attached is a pic of the socket 775 cooler that is normally shipped. The 3 gray/black strips on the bottom of the heatsink is the thermal interface material.

    Some people occassionally have problems installing the socket 775 cooler. It is sometimes easier to install the processor and cooler with the motherboard out of the case. Whether the board is in or out of the case, if you follow these instructions you should have no problem.

    These instructions are for installing a standard Intel socket 775 cooler. These instructions apply to Intel coolers that were shipped with pre-applied Thermal Interface Material or Thermal Interface Compound.

    BEFORE STARTING THIS PROCEDURE MAKE SURE THE POWER SUPPLY IS DISCONNECTED FROM THE POWER SOURCE.

    If the new heatsink has a thermal pad pre-installed, it MAY have a piece of clear cellophane covering the thermal pad. If the heatsink has this clear cellophane covering the thermal pad BE SURE and remove it before installing the cooler.

    Turn the locking pin assemblies until the notch on the locking pins is perpendicular to the heatsink. Make sure your fan connector wire is clear of the cooler and is as close as possible to the motherboard CPU fan header. Re-align the locking pins with the holes in the motherboard. Push down HARD on 2 pins at a time diagonal from each other, until all 4 pins are fully down and locked. After all the pins are down and locked, push down HARD again on all 4 pins one at a time. Connect the CPU fan.

    It is extremely important that the heatsink be in contact with the processor heat spreader under pressure. If the heatsink is not in contact with the heat spreader under pressure, the machine will either fail to boot or will run for a few seconds and shut down.
