First, make sure you are installing them in the correct slots, which are the A2 and B2 slots. Those are the second and fourth slots to the right of the CPU socket.

And you've tried that stick in both slots, by itself? Have you tried installing that stick and then doing a hard reset of the BIOS, to see if it works then? It may be that there are too many differences to the timings between those two sticks. It doesn't matter if you THINK they are similar, if they did not come together in a kit there may be major differences in the secondary or tertiary timings and the motherboard may simply not be reconfiguring itself well enough to run the memory.

Try the single stick, and do this. If it doesn't help, then the memory is probably just not going to work in your board. Not all memory will work in all boards, which is why there are QVL lists. QVL is mostly useless, but it does go to show that even the manufacturers acknowledge the fact that some memory might not work in their motherboard.

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.
 
That shouldn't matter Calvin. It should still recognize and default to a lower speed that IS supported unless of course it simply does not like the memory at all, period. Besides which, the board states support for memory up to 2666mhz and we know that historically the board is what really matters. Intel has often only stated support for speeds up to the default and not listed any overclocked or profile speeds. It should work.

Plus, he clearly states that they both work individually, just not together. That would not indicate a problem with the speed.

I would try bumping up the DRAM (memory) voltage in the BIOS by .005v, if they work singly but not together. Install one stick, increase the DRAM voltage by .005v, save settings, shut down, install the other stick, power on. If no love, do the same thing again and increase by another .005v. Repeat until you have increased voltage by no more than a total of .020-.040v. If they don't work together by then, I'd return the memory.
