Solved 12GB RAM installed, MSI Motherboard only recognizes 4GB

October 23, 2013 at 13:32:07
Specs: Windows 7 64 bit, 12GB
I have had a 4GB RAM stick in my MSI Motherboard for about 3 years (Windows 7 64 bit), and decided I wanted to put in the other 2 sticks that came with the 12GB kit. Everything ran fine, checked DXDIAG, and it still only reads 4GB. Does that mean that the other 8GB aren't functioning, or is it just showing 4GB in the report even with 12GB working? After I installed, it was obvious the system detected the new hardware and installed necessary drivers, all of which were successful.

How do you have the RAM slots populated? You need to consult your MBoard manual to see how the three modules should be installed in order to run in triple channel mode. Speccy indicates you are running in single channel mode.

This may be due to installing the modules in the wrong slots, a BIOS setting, or you may need to reset the CMOS.

There are lots of advanced settings for memory in the BIOS.

There are several BIOS updates that refer to memory compatibility. This indicates the board is fussy about what RAM it can successfully run.

There is a reset button on the board that I am not sure of the function.

Are you sure that you ran the 64-bit version of dxdiag, not the 32-bit one? Anyway, why use that to determine system memory? Have a look at the system details in Control Panel or just fire up Task Manager and see how much memory it reports.

Task manager shows only 4GB, and yes, it was 64-bit DxDiag

How much ram does the motherboard support? 4gig is usually the limit on 32bit machines. Also you may want to remove the original 4g stick and see if it boots with the other 8 at all.

It's a 64bit machine. If the other 8GB didn't read, why would it detect them and install drivers, but not register them in the total memory?

Strange answer. Memory modules don't need drivers. Does the BIOS show the full memory? If so, you should check in msconfig to make sure that there is no "maximum memory" setting.

It might help if you told us the model of the motherboard and the make and part number of the memory modules.

Here's where my knowledge starts to dwindle a bit. I "built" this computer with a friend of mine, but he was definitely the brains behind it. When I referenced the drivers being installed, all I noticed was when I put in the new RAM sticks, I had to Clear CMOS in order to get my computer to "post", BIOS needed the date and time changed, which I did. When I got to my desktop, window at the bottom right said Windows detected new devices, and was installing drivers accordingly.

That being said, what's the most efficient way of looking up my motherboard part number? It's an MSI "Big Bang", if that helps. Also, the RAM are G Skill Rip Jaws, 4GBx3 kit. Would part numbers be on the sticker on the front of those?

"It's an MSI "Big Bang", if that helps"

There are several "Big Bang" boards, you're going to have to narrow it down. After you reset the BIOS (Clear CMOS), did you run thru ALL the BIOS settings & correct as needed, or did you just change the date/time? Loading defaults (which is what you did) is just a starting point, it's never 100% optimal.

Big Bang Boards

Other than that, you didn't state which RAM (DDR3-133, 1600, 1866, etc) or which CPU you have. It's difficult to provide quality answers when we have no idea what hardware you're working with.

Are you sure you have the 64 bit version of Windows? Just having a 64 bit processor is not enough. To check, go to Control Panel> System. The information should be shown there.

I'm sure I have Windows 7 64bit.

I'll give you all the info I can, if you can tell me how to get it. Also, I DID just Load Defaults, because that's what I was instructed to do by the guy who built this machine with me. I'll gladly change something else if y'all think it's worth it. How do I get the information on the CPU, Motherboard and Memory for you guys?

Can anyone else vouch for this Speccy? I'm always a bit leery about downloading unfamiliar software.

This is the result of the Speccy scan. It registers all 12GB for some reason, but DxDiag and Task Master don't...

So I did it! I cleared CMOS, installed the other two sticks, and went into the BIOS to change the power arrangement to 10-10-10-24 on the RAM, picked it up right away. Thanks for all the suggestions guys!
