My motherboard and ram don't quite go well together, my motherboard support ram with speeds up to 1600mhz, but my ram is 1866mhz. What will happen when I try to install the ram in? Will the ram explode? Or will it just be bottlenecked and forced down to 1600?

Why wouldn't Bios support ram sticks

Any speed over 1600 is technically outside the DDR3 specification, unless it's changed drastically since I built my last system. Typically, the RAM will get clocked to 1333 or 1600 depending on the motherboard and BIOS unless you specify an XMP setting or manually clock it yourself.

With regards to BIOSes not supporting DIMMs, if the DIMM only supports speeds the BIOS/Motherboard don't, then you'll have issues, basically. That said, the majority of RAM clocked to 1866+ has base clocks of 1333/1600 for compatibility purposes.

Do you even know what the BIOS is and how it works? Here is a short explanation.

The BIOS includes instructions on how to load basic computer hardware and includes a test referred to as a POST (Power On Self Test) that helps verify the computer meets requirements to boot up properly. If the computer does not pass the POST, you will receive a combination of beeps indicating what is malfunctioning within the computer.

The four main functions of a PC BIOS

POST - Test the computer hardware and make sure no errors exist before loading the operating system.

Bootstrap Loader - Locate the operating system. If a capable operating system is located, the BIOS will pass control to it.

Drivers and Firmware - Low level drivers that give the computer basic operational control over your computer's hardware. A list of Supported CPU's, RAM specifications as well as peripheral device specifications.

BIOS or CMOS Setup - Configuration program that allows you to configure hardware settings including system settings such as computer passwords, time, and date and overclocking.

If the BIOS does not have the support drivers in it's firmware for a specific brand of RAM it will not work. Most PC board BIOS now support up to 2400mhz RAM but the CPU's themselves may only natively support 1333mhz,1600mhz or 1866mhz. FX chips for instance natively support 1866mhz so generally you have to overclock your RAM to get them to the listed Value over 1866mhz, while Intel natively supports 1600mhz. Most AMD FM2+ Chips while natively support DDR3-2133.

Yes that will work fine, I'm guessing you have the Motherboard because I haven't seen those sold in awhile.
