Hello I have a Ga-990fxa-ud3 rev 4 motherboard and a fx 9590 cpu. I have 4 8gb non ecc 240 pin 1600 mhz memory sticks and am running windows 7 64 bit. Problem is when i put over 16 gb of ram in computer wont show me start up screen. all ram are the same brand and works just fine if only using 2 sticks.What do I need to change 2 get it to run 32 gb of ram?
 
Solution
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, particularly AMD can be very sensitive to this.
This is more difficult when more sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.

My only suggestion is to install two working sticks and enter the bios.
There, increase the ram voltage a notch.
Shut down and try adding the two remaining sticks.
Sometimes adding voltage will make things work.
