Ram not showing up in bios

I have 4x4 gigs of ram. Only 3 of the 4 sticks show up in the bios. I narrowed it down to a single chip. When I try to run with only the suspected chip in I get an error code 53 on my asus x-99 deluxe which means memory issue and it will not start. However once I start into windows with all 4 chips in, I see 16 gig in system. What is going on?

EDIT: Task manager also shows a full 16.

Have you did any RAM test to actually see if all 4 sticks are getting filled full of RAM/don't crash or anything else of the sort?
That's quite the oddity you got with all 4 sticks not showing up in BIOS but they do show up when in OS, quite the oddity indeed.
Have you also tried taking out all of the RAM sticks and leaving in each one 1 by 1 to see which RAM stick doesn't boot/shows an error code/won't boot into Windows?
Information like this is needed if we are to help you any.

I mentioned that I narrowed it down to a single chip and I tried a couple different slots with it. It will not start with the suspected chip in it. It leaves are error code 53. I will try some software to fill the ram with.

EDIT: I was able to fill over 10 gigs of ram with memory filler and the system was using about 30% before. SO the ram is there, but why does the bios hate my ram chip? It used to be fine.

You said you were only able to fill 10gigs or over 10gigs all the way to 14-15gigs? (it'll only do this because Windows/the Motherboard likes to keep at the very minimal 1-2gigs of RAM free incase of emergency uses)

So how much did you actually fill? If it didn't get to 14-15gigs, then that RAM stick isn't being used at all/possibly defective. Quite strange how your computer will even boot into Windows at all with it in.

well before I filled the ram the system said it was using 30% I went and filled over 10gigs. That seems about right and the task manager claimed I was using like 15.5gigs.
