16 GBs of RAM not working on ASUS motherboard

Hey guys, I'm new here and I've been having a lot of trouble with my ASUS M4A785TD-V EVO motherboard. It's rated to be compatible with 16 Gbs of RAM but the last two sets I've purchased from newegg haven't worked at all!

I tried mixing old RAM with new and it still won't work. It only works if I use my old RAM

RAM that works: Crucial 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600)
First attempt at 16 GBs: G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500)
Second attempt: Kingston 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600)

Only the original Crucial memory works. When i tried the other two, nothing would show on the screen.

Any help here would be awesome and much appreciated!

EDIT: I tried googling for help and found a forum post on here already on the same subject when my first attempt didn't work. That's what pointed me to buy the Kingston RAM. It was recommended by a user here and it still didn't work.

EDIT 2: Problem has been solved. I had to update the BIOS of the motherboard to fix the problem

Hello Randomrocket. Welcome to the forum.

I assume you have already checked to be sure all RAM you are trying to use is the same specs as the current RAM, most importantly the voltage spec, but also unbuffered, and the timings should be the same or very close.

That said, the first thing you need to determine is whether it is a bad stick of RAM or a bad RAM socket or a power problem.

The first thing to do is remove the old working RAM and add one stick of new RAM into the first blue slot (A1) and test. Test each new stick in A1.

If that works then install the 2 new sticks in the same locations as the old sticks (the 2 blue slots - A1&B1) and test.

Then, with the two new sticks still in A1 & B1, add one stick of the old RAM into the third slot (black - A2) and test. Then the second old stick in the last slot (black - B2).

Report back what you find.

That is bizarre! That indicates that the RAM sticks are no good. One stick - sure. Two, maybe. But 6?

I guess the best thing to do is RMA the two 4GB sticks and get another set of four 4GB. One of the sets has to be good.

It should not be. The board was designed for 16GB on the first version of the BIOS.
You could look to see if they have any BIOS updates that specifically address RAM issues. If so, then it would be worth the risk to flash.

And, while it should not make any difference at all, you could try resetting BIOS defaults (note your current settings first) and then try the new RAM.
