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

Ill order another set of the Kingston so that way theyre the same

The Kingston RAM is very small... its kind of weird. First I thought I ordered laptop RAM on accident but I checked the part number and it matches... Its about half the height of normal desktop RAM.

Interesting. I never would have noticed if you hadn't pointed it out, but when you look at the picture of the Kingston RAM it looks perfectly normal. But upon closer inspection you can see that the Kingston RAM has 2 circular notches on the side, and the Crucial has 3! Good info to know, thanks!

The Ripsaw RAM also has only 2 notches. Was it short too?

no.... wow, now that I look at the Kingston picture on newegg, it looks normal size but it is definitely not the same as the real stick! I can take a picture in a sec comparing them to my old RAM...

Sometimes the manufacturer changes the card design, uses larger capacity memory chips, which take up less space.
If they get it right they will work with the older larger cards, but it is possible to cause compatibility issues.

It is down to luck most of the time, the same part number RAM cards from a different batches sometimes aren't compatible.
That is why it's recommended to get all your RAM in one kit.
Mixed brands and kits can and do work together but, not all the time.

Sorry for the horrible quality picture, I don't have a decent camera for taking pictures but you get the idea of size comparison...

You won't benefit from using Quad channeling on a Dual channel motherboard.

Good guess. If you have a board a couple of years old with the original or old BIOS, the BIOS would be high on the list of suspects. Manufacturers like to advertise a mobo will take XX amount of RAM, or the next generation CPU. What they leave out is that it will require a BIOS update to enable the upgrade.

Not too much trouble with RAM. But sometimes a user will install a new CPU only to find they need to flash the BIOS which will mean re-installing the old CPU to do it.

Glad everything worked out for you, enjoy.

It looks efficient. The memory chips look to be about the same size. Less redundant plastic. I like it.

It might stay out of the way of the really big CPU coolers.

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.

I understand that it will work, although some mobos are known to not run with 4 sticks installed. What I mean is that you will not get the benefit from using 4 sticks of ram in a dual channel system. You will get the ram but its not going to be any faster, and in some cases it can be slower than using 2 sticks that equal the amount of ram you want.
