    Question Z77 Extreme4 Questions

    Hi
    When PC is off the Green LAN light is on and the Orange LAN light is blinking should it be this way? Can I turn it off?

    Also I miss 114MB memory that are reserved for hardware, could this be the XRam feature?
    But I didn't set anything for it in the AXTU.
    Or is the onboard graphic of the Ivy?
    Or something that is set in the BIOS?
    I'm running W7 64 so there shouldn't be missing any memory like you see it under 32bit.

    Can someone tell me where the MB temp sensor is placed?

    Concerning your light question, my lights turn off when I power down. Did you install Intel Smart Connect? When your computer is in sleep, it's supposed to reconnect to update your social networking stuff and e-mail or some such.

    The reserved RAM I believe is normal. I have the exact amount you have reserved. The usable memory may be less than the installed memory on Windows 7-based computers

    No Smart Connect installed, at least not the drivers, I check if the BIOS Option is really disabled but I think it is.

    Yes Smart Connect is off, I thought it could something like Wake on LAN but all those options are off too.

    Can anyone tell me where the PCH temp sensor is placed? Isn't it the sensor for the MOSFETs?

    It's not unusual for a mother board's network chip or a separate network card to remain active when the PC is shutdown. My Z77 EX 4's network chip activity LEDs are on when the PC is shutdown. That is not a problem or indicates something is wrong. Check the Device Manager entry for the Broadcom network chip, and check for a Power Management tab, you might find a setting to power it down with the PC. I'm using a separate network card (whose LEDs stay on when the PC is shutdown) so I can't check the Broadcom device entry now. They were on when the PC was shutdown, when I was using it. The Windows Power Plan you are using may also affect the network chip.

    The PCH on this board is the Z77 chipset, the Platform Controller Hub. It has a built in thermal sensor, it's part of the chip.

    Thanks I will check that.

    Looking at the motherboard layout(p.13 in the manual) I guess it would be #10.
    No wonder it gets warm, seems to get hot air from the graphic card, I wonder if temperatures would improve without the strange metal cover, did anyone try to remove it?

    Very Bad Idea. The metal cover is most likely there for electromagnetic shielding. Remove it, and you open the can of worms known as "interference."

    The cover on the heatsink of the Z77 is all for show IMO, very common now, a bare heatsink would not be pretty. It might cool a little better with it off, but you can't just pry that cover off with the heatsink attached to the Z77, since the heatsink is not attached to the board very solidly. I would just leave it, and try to get some more airflow through the case to cool it. What temperature are you seeing for your PCH?

    Actually, most Intel chipsets run rather warm, and their maximum temperature is at least 100C. Some of the old 4 series Intel chipsets did not even report a temp below 50C.

    Well while gaming it gets into the upper 50's.

    The upper 50's is not bad, and should not compromise the chip. My case has a side fan mount that blows air directly on the chipset area of the board, and at idle and a cool room (ie, not summer), my PCH temp is 43C - 47C.
