Windows 7: 16 GBs of RAM not working on ASUS motherboard

What you mean is the OP will not get Quad-channel speed benefits with a dual channel system. Yes. But this motherboard won't take more than 4GB per slot according to Asus; so the OP can't buy two 8GB sticks for a dual-channel install to equal the same 16GB. What the OP has bought will work to give a greater amount of RAM if that's what is needed for say video encoding.

Makes sense. I didn't really read the whole thread since it was already solved, I probably should have done that in hindsight. I just wanted to address the mistake a lot of people make by trying to install 4 sticks into their dual channel system.

Just to clarify things - there seems to be some confusion.

In all of my preceding comments I am talking about RAM kits.
In all instances it was always assumed that we are talking about individual RAM modules of the exact same Brand, model number, and specification.

When buying RAM with the exact same Brand, model number, and specification it will not matter whether you buy 4 individual sticks all at the same time, two 2-module kits, or one 4 module kit. It is all the same RAM.

RAM modules sold in a "Quad Channel Kit" is not special. It is just 4 matched modules that came off the same run to minimize the problems that can occur when you mix the modules from different manufacturing batches (runs). (Keep in mind that these issues usually only come up when you are overclocking.)

4 sticks of RAM sold in a Quad Channel Kit will work perfectly fine in a Dual Channel system. The modules are dumb. It is the motherboard that determines what mode the RAM modules will run in.

Hope that helps clarify things.
Agree with TVeblen.

A four RAM slot, dual channel motherboard has two RAM slots for each channel.
When you have two RAM cards you need to put them in different channels to get the maximum performance.

The new four RAM slot, Quad channel motherboards have four channels.
They all use the same RAM, the number of channels on the motherboard is the only difference.

A lot of people, including me, have run four RAM cards in dual channel systems with no settings adjustments needed and no issues.

If a system won't run with four RAM cards, usually it needs some settings adjustments.
RAM voltage, NB (North Bridge - separate or integrated) voltage, it depends on the luck of the draw of the components and how they work together.
Sometimes the frequencies and timings may need adjusting.


There have been a few motherboards that just refuse to run four RAM cards, but not that many of them.

I just want to clarify that I specifically mean that in a dual-channel system, using 4 sticks of ram increases the load on the bus. This means that it's slower than using 2 sticks in a dual channel. Like you said, it "works" and in the case of the OP, it's necessary.. but if you're looking for performance, 4 sticks in a dual-channel system is not the way to go.

Sorry, but have to disagree.

My OEM dual-channel system RAM performance is just fine with four cards installed.
2x2GB and 2x1GB.

Are you having performance issues with your 6GB?

OEM systems can be harder to get running smoothly, if the RAM isn't matched, due to the limited BIOS.

It's not a huge difference, you may not even really notice it unless you benchmark it (I've only seen one benchmark test this and performance was lower with 4 sticks). But it is a fact that 4 sticks in a dual channel system slow it down a little. The memory controller has to work harder to pull information from each module and it puts more traffic on the bus, creating more latency.

Got my 16 GBs working now and I can't tell a difference on speed... Check my system specs if you want

Congrats, glad to hear you got it running stable.

Now you can enjoy your system.
