    The processor should be smart enough to run the memory in mixed mode / hybrid dual channel / whatever you want to call it. 

    The portion of memory that's available on both channels will run in dual channel mode, the remaining portion will run as if it's single channel mode. 
     
    Dual Channel is like having the memory run at DOUBLE the frequency but not quite.
    Basically, single channel means that on every tick (hz) , the processor can read or write 64 bits of data into a ram stick (8 Bytes) . In dual channel mode, the processor reads or writes on both channels at the same time, so on every tick / Hz, it now reads or writes 128 bits or 16 bytes. 
     
    If the processor needs to read or write 1 MB of data, in dual channel mode the data will be read almost twice as fast. 
     
    When the processor requests some data, there's an initial delay from the moment data is requested until the data is available and can be read from the memory chips. That's the latency and other timings written on the memory stick. Once the stick is ready, the data can come in a burst. 
     
     
    So set everything at the frequency and timings supported by all sticks, probably 1066 Mhz. let it be in dual channel / mixed dual/single mode... use 3 sticks if only 3 sticks work. It will be better than 2 sticks with higher frequency.

    I would just seek a replacement board personally,..over buying more Ram for it,..just be strict with whatever budget you have and be patient with seeking a replacement, don't impulse buy and check on what you are buying.
    Or live with it for a year.

    DualRank (4x4 SR turns into DR) 1066Mhz will perform better than Single rank 1066Mhz (just an example), and perform probably like 1333+ Single rank and make up for some speed losses, but if it's enough I'm not sure, if it's noticeable when GPU bound, not sure,.
    But if I was going to lay down cash, I'd get the board, squeeze the 4x4 again and try for Dualrank 1333/1600Mhz Auto OCs/Manual OCs.

    Dual channel 1066Mhz has better total bandwidth. Just be sure to tighten the timings. Single channel would need to be 2133Mhz (double) or better to be the better option.

    Since you already have the RAM and 4x4 at 1600mhz is fine, I just suggest you to get a new (in this case used) motherboard. Z77 boards are pretty cheap nowadays. You could even upgrade to a Z87 or better for your 1155 socket. Just make sure you find a board that fits all your needs, especially for overclocking and the amount of connections on it.
