    Default ASRock Z68 Extreme4 Gen3 pin problem

    I have built a new system based on an Z68 Extreme4 Gen3 board and an i7 2600K CPU.

    When I turn on the system, the following happens:
    CPU fan spins up, but Dr Debug LED doesn't light up, no beeps. According to ASRock documentation this is a sign for missing or bad CPU.
    My PSU is ok for sure, since it works fine with another board under heavy load (GTS 8800). I removed all disks and USB connections, still got the same problem. 20+4 and 4+4 connectors are firmly plugged in. Reset button on main board doesn't seem to work (no beep ever). I also played around with various RAM combinations.

    Then I have examined the pads of the cpu and the pins of the 1155 socket.
    Here are the results, very weird:

    http://www.blackmoongames.ch/asrock/cpu2.jpg
    http://www.blackmoongames.ch/asrock/cpu3.jpg
    http://www.blackmoongames.ch/asrock/cpu4.jpg

    http://www.blackmoongames.ch/asrock/sockel_low.jpg
    http://www.blackmoongames.ch/asrock/sockel_high.jpg

    There are about 35 cpu pads which have absolutely no signs of contact with a pin. Then there are quite a lot pads where the contact is not in the center, but close to the edge. You'll notice that some of those have 2 marks from their pins. That's because I removed the CPU once and put it in again. Please note that most of the marks are perfectly centered.
    However when looking at the pictures of the socket, all pins seem to be ok and perfectly aligned (remember board and cpu are brand new).

    Looks like there are some pins which don't behave correctly when under pressure.

    Can anyone confirm that those bad contacts account for the system not starting up (seems obvious to me)?

    Has anyone else experienced the same problem?

    Thanks for your help,
    Thomas

    It helps us when you include a detailed hardware list in your forum signature.

    I don't see any socket pin alignment problems, but you should carefully inspect the height of the socket pins that don't seem to be making contact with the cpu pads. Make sure that the pins and the bottom of the cpu are completely clean.
    Looking at my four LGA775 processor photos, all of the cpu pads show one or more contact points where most of the contact marks are centered. This applies to all of my cpus.

    thanks for your hints, I'll have a look whether they all have the same height
    (if it's possible to see that at all)
    the pads are clean. the pins seem to be clean, too. (trying to clean would kill them anyway, I guess?)

    I didn't find any way to edit my signature in the settings or my profile...
    (the faq talks about a "user control panel" which doesn't seem to exist any longer)

    The best and safest way to clean the socket pins is to use compressed air from an aerosol can.
    Checking the pin height won't be easy.
    You might be able to take several closeup macro pictures of the socket's pins, but you would only be able to view a few pins in each photo.
    Can you borrow another power supply to test with before you RMA your motherboard?

    Great socket pics! Looks fine to me too, what cooler are you using and are you 100% sure it's fully and properly seated? If it's the standard Intel stock one, you may need to redo it and be sure that all four corners click down and lock in place, this is best done with the motherboard removed from the case and motherboard tray. Sounds to me like the cooler is not fully seated, thus making the CPU not fully contact with the socket, leading to the board never starting.

    Been there before, but I only see menus like My Settings->My Profile->Edit Profile (where I can edit information like location, biography, interests, ... Maybe I'll abuse one of these?)

    I used the standard i7-2600K cooler. I think it was seated correctly, but could be worth a try. However I have the impression that the locking mechanism for the CPU puts enough pressure on the CPU to make good contact (that's what it is designed for, isn't it?). Thanks for the hints. Next time I mount the cooler, I'll remove the board from the case, I'm always afraid to break the thing with the standard cooler. (I'll use my old Noctua NH-12 once everything is running. I'm just waiting for the 1155 CPU adapter, that Noctua sends out for free, if you have an old adapter. Great service!)

    As you said, checking the pin height won't be easy, if possible at all. Taking photos from the side is near to impossible, I guess (too many other components in the way - and also the depth of field problem that you mention).
    I don't have access to another PSU. The PSU (beQuiet 600W) runs fine with my old system (Q6600, Asus P5KC, NVidia 8800 GTS 512, 3 hard disks) at full load (3D gaming etc.).

    I always build and test my systems outside of the computer case.
    When installing the Intel cpu cooler, I find it much easier to do it with the motherboard out of the case, where I can support the underside of the motherboard with my other hand. I connect each push-pin connector using a cross pattern, for example top left -> bottom right -> bottom left -> top right. When I'm done, I firmly pull on each push-pin one at a time to ensure that each one is firmly connected. It is possible that one or more push-pins are not fully seated. Make sure that there isn't any debris that might prevent the cpu from seating fully in the socket.

    It's possible that there is an incompatibility with your psu and motherboard.

    Does your camera have a macro tele-zoom option that would let you shoot from farther away but still get a close-up photo of the pins?
    It sounds like your psu has 2 4-pin ATX_12V connectors. Verify that each connector is fully seated and that they are installed correctly.

    I was just thinking maybe you didn't get all four corners fully inserted and then locked, it happens often because they aren't always set properly before being pushed down into the holes. Be sure you pull them all up when you remove it, or anytime you are putting on a new one, then twist each one clockwise until it stops while it's pulled all the way out, then it'll lock and snap when you press them down into the mounting holes, and you'll have to turn counter-clockwise to unlock and remove them.

    So, you don't see this in your options page I linked above? If not, maybe you need xx number of posts before you can add a signature, I'll check for a setting on that right now and see if that's why
