    DP45SG MoBo working without Power Connector # 19

    Hi guys...,
    I have an Intel DP45SG motherboard, I built my system a long time ago; when this mobo was recently released from Intel. It has worked perfectly for since than... I was running it with only half of the maximum RAM capacity (at 4GB). As things go on, I just upgraded my video card to the GTX 1050Ti, since it has 4K playback, and I have my PC directly connected to my new 4K Curved TV... Fantastic image.

    Issue is as follows, I noticed that I haven't got plugged in a 12v (1x4) power connector to the desktop.
    this is located just on top of the 1st PCIex16 slot, behind the audio Line(s).

    Showing to missing power connector and to RAM slots in use...

    However, note that as per the installation guide/map; there are in fact two "Power Connector # 19"
    a. the missing 1x4 12 V
    b. a 2x2 12V, connector that actually on the top-left corner of the MoBo; which I do have in use...
    I can't remember is this a "one-or-the-other" or "one-and-the-other"..?

    Like I said, the system seems to have been working perfectly... no crashes, slowness or anything.
    Except for the fact that
    * as I wanted to add more RAM,
    the BIOS won't take anything else other than what I built the system with.
    * I can't fill the other 2 slots...
    * I can't remove the old RAM and insert new ones
    * It only works with the original RAM I started with.

    Also, I am afraid to plug in anything there. It looks like an old IDE Hard Drive power connector; but I get goose bumps just thinking about it.

    So, do I need that power connector there..?
    Can I use a regular old IDE HDD power connector there..?

    Yes, I would like to fill to capacity the 8GB RAM (4x2GB) from my current setup of only 4GB (2x2GB).

    Welcome to the TenForums.

    According to specs that connector is for "Auxilary PCI Express Graphics Power". Page 19


    Don't understand why it won't let you add memory so I would suggest you have it forget what it has. Shutdown, unplug, remove CMOS battery, press power on for 20 secs. Change memory, replace cmos battery, plug in, enter setup, save defaults, assuming that is what you had, boot.

    Always some risk. Manual likely has other suggestions and warnings.
