I recently purchased a Gigabyte Z87-UD3H motherboard and with it 2x4GB 2400MHz Kingston HyperX Beast memory. I also have a i7 4770K processor.

My question: I enabled the X.M.P in the BIOS to allow the memory to run at the 2400MHz but if I go to the Gigabyte Easytune application, it says my Max. Bandwidth of my memory is PC3-10700 (667 MHz), but the memory is rated at PC3-19200.

Is there a way I can overclock my motherboard to allow more bandwidth or is it not possible?

First of all the memory controller is on the CPU not the motherboard, the 4th generation CPU memory controllers are designed to run at either 1333mhz or 1600mhz your 667mhz x 2 for dual channel = 1333mhz.

You can BIOS manually set the memory controller to run...

id say try to view it directly through the BIOS. i remember on my Z77X-UD3H you can view the rated specifications of your ram modules in like MIT tuning or something along those lines. you could also try using CPU-Z

not gunna lie though, i do have a pair of Kingston HyperX DDR3-1600 4gb @ 1.65v which had PC3-12800 specs and when i checked the specs through CPU-Z it did show 10600 instead.

You can BIOS manually set the memory controller to run 800mhz x 2 for dual channel = 1600mhz, but running it up to 2400mhz, faster than it was designed to run, is going to increase the heat output of the CPU, shorten the life of the memory controller, and probably end up with stability issues.

There's a lot more to learn today than will this memory module fit my motherboard even though you're being told the 2400mhz will work in the motherboard you chose, and it will work as it defaults to the safest run speed and you have to (OC) to reach the higher speeds listed it can handle.

But is that the best thing for the CPU itself.

Just because you can, doesn't necessarily mean you should, if you're concerned with your CPUs longevity at all.

Additionally if you have any raising multiplier overclocking intentions and you're forcing the memory controller to run overclocked out of the gate don't be surprised when you hit the so called overclocking wall sooner than you should, and your CPUs heat load goes through the roof.

Also go check tests on 1600 through 2400 on YouTube. Not much difference from 1600 to 2400. The best performance came from 1866 but not by much. So really, if you have more than 8gb of 1600 DDR3 RAM, you should be ok. Dare i say no need to OC? I would worry more about OC'ing the APU and GPU
