I really need help! It's been 4 months almost, and I have not gotten a solution!
I have two 4 GB RAM Sticks, adding up to 8 GB. They both work. The BIOS detects them. Windows 8.1 64 Bit detects them. But... 3.9 usable. The BIOS recognized two 4 GB sticks, but is using only 4080 MB. I have tried everything.
I reseated the RAM, enabled remapping, updated BIOS, did something from a large post, something about changing the RAM speeds, I manually set the frequencies, voltage, etc. I RMAed the motherboard! I tried one stick at a time, they both work. I selected and deselected Maximum memory in Windows. I reseated every component! I've done EVERYTHING! I can't think of all of the things that I have done, but I need help, please!
Please, please help... and thanks for whatever help I can get.

download a program called CPU-z and look at the memory tab, and take a screenshot and upload it

They are 1866 sticks, what's the brand and model # - also what CPU and mobo

RAM: G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBXL
CPU: AMD FX 6300
MOBO: ASUS M5A97 LE R2.0
By the way, I have a brother with the same pc with the same components, and his RAM is recognized. Tested his RAM, no good results.

May have a week MC, try DRAM voltage at 1.56 if no joy there, then leave that and raise CPU/NB voltage to 1.2

well CPU-z is only reading single channel...even with 2 sticks in? that's not a good sign. this will sound dumb and I don't meant to belittle your knowledge but the RAM sticks are in the right slots? color matching, not necessarily one next to the other. either put both in the blue or both in the black slots. *not* one in blue and one in black

What BIOS version are you running? If your running an older BIOS, then there may be a newer one to address memory issues. Here is a link to ASUS's Support for your motherboard. ASUS M5A97 LE R2.0

I tried every slot, and no luck. Right now, they are in the blue slots.

I think I will try testing each RAM stick at a time once more. Otherwise, I will do what you said.

Err, know anyone with two ram sticks you can borrow and test if they work?
It sounds like something is wrong with the ram (or the mobo, but you said you RMA'd it already, its not impossible to get 2 broken boards though)
Check this out maybe: http://www.tomshardware.com/answers/id-1636054/9gb-usea...
"I had the same problem.

I think that the answer to fixing this problem is to reduce the speed of the RAM manually by one speed level in the BIOS I reduced mine from 1600 Mhz to 1333Mhz. (The actual hardware speed of my Crucial chips are both 1600MHz. My RAM chips are both Crucial BLS4G3D1609DS1S00. They are not recommended by ASUS for the board. The nearest recommendation is Crucial BLT4G3D1608DT1TX0.16FM(XMP). Maybe the motherboard's BIOS is not stable yet. I loaded the latest BIOS version ie. Version 2101 dated Oct 2013 but this didn't fix the problem.

I then turned off the whole computer at the power socket in the wall. Afterwards, I switched the power on at the socket but made sure that I did not press the power button on the computer. (You must do it this way to get the MeMOK! button to work). I pressed the MeMOK! button on my Asus M5A97 R2.0 motherboard (It is near the RAM chips on the motherboard - see the manual of the motherboard). The MeMOK! light flashed a few times and made noises. The computer loaded up to the point on the BIOS where it asked me to press the F1 key and then save the changes that it made to the BIOS. I did all this and the system recognised my 8GB of RAM.

If this does not work I found that I got it to work by turning off the computer at the wall socket so that there is no power lights on the motherboard again. I then took out both the RAM chips and put them back into the same slots again (ie. the two blue sockets). I think that this seemed to tell the computer that the chips are new chips on the board. I turned on the power at the socket and then pressed the MeMOK! button again. The computer loaded up the BIOS to where it asked me to press the F1 key and then save the changes that it made to the BIOS (ie. save the changes when you exit the BIOS). I did all this and I found that I got the BIOS and Windows to recognise my 8GB RAM.

I found this out because I took out my RAM chips to find out their speed etc. After I took them out the system recognised my 8GB of RAM but said that only 3.9GB was useable again as before. Once you have got it to work leave your RAM chips in the sockets and there won't be any problems.

You might have to do all this a number of times to get it to work. I can't guarantee that it will work for you but I can say that it has definitely worked for me. I have since shut my computer down and reloaded it a number of times and it still recognises the 8GB without any problems.

(As you know to get into the BIOS on an ASUS you press the delete key or the F2 key when the message appears on the screen when you are loading up the computer (ie booting the computer). I write this to help others that don't understand how to get into the BIOS. Then you click on the "Advanced" button (F7 key or use the mouse if I remember correctly). Find the "Memory Speed" (I think it in the "Tweek" menu and change it. Then save your changes when you "exit" from the BIOS.)

I now have the full 8GB working properly without the 3.9GB useable message. I also notice that the Microsoft RAM speed moved from 5.9 to 7.4 when I did a new Speed check. It seemed to think that I changed my hardware and asked me to do the speed check again after I fixed the RAM to work properly. Everything works beautifully now.

This all looks very complicated but it isn't really. I have tried to includes as much detail as possible so that anyone can do it. Print this out to help you do it."
