Why does 18GB of RAM report as only 2GB in Windows 8 64-bit?
I am using Windows 8 [64-bit] and 6 x 3 GB DDR RAM, however the computer itself lists 2 GB (installed) which is impossible since even if only one stick were to be recognized it would at the least be 3GB of RAM installed.
Again I have Windows 8 64-bit as the operating system, so the cap on 32-bit systems for maximum RAM is not the issue.
- Intel (R) Core (TM) i7 CPU 920 @ 2.67 GHz
- Installed memory (RAM): 2.00 GB
- System type: 64-bit Operating System, x64-based processor.
I am truly baffled as to what steps I should take. Does anyone have any ideas on how I might fix this issue? Do you have any trouble-shooting tips? Thanks.

the bios recognize the 18 Gib of ram ? If yes the OS should recognizes too.Try replace Windows 8(tm) by Linux.Gnu/linux doesn't this problem ;)

That shouldn't be true, I am sure it is your mistake, It is not possible at all 18GB report 2GB.

As Jan said, it is impossible to have a 3 gb RAM module. I think he may well mean that the RAM is DDR3 (as opposed to DDR2 etc). It could be that his system is not compatible with DDR3. I suspect the system came with 2 gb of DDR2 RAM and the user has upgraded to 18 gb of RAM. This would explain why Windows recognises 2gb of RAM but not the 18 gb of RAM. A scan at crucial memory and / or using Speccy may help to identify what RAM is installed and compatibility.

windows 7 is only using 11.9gb of ram with 16gb installed http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/windows-7-is-only-using-119gb-of-ram-with-16gb/27297c93-c9cd-44b5-a82a-4d99c35a01ad

If it is DDR RAM, that is probably part of the problem. The boards I am familiar with that support his processor require either DDR2 or DDR3 and if he is using DDR, it's going to have problems.And 3GB RAM modules don't exist AFAIK. And I know miles.Christopher, go to
CPUID
, download and install CPU-Z. Run it and select 'Save report as .TXT' from the Tools menu. Post the results here. It will give us all kinds of gory technical details about your motherboard, memory and video card installed in the system.

you have to use an ECC supported motherboard to use the ECC feature of the ECC rams, (ECC function within the BIOS), you can use both in a Non-ECC motherboard but some motherboard will not accept an ECC module, depending on the BIOS version. Some server have a bios hardcoded to fault if ecc is not present

Thank you for your input Jan, I do truly appreciate any help here.

Maybe it is important to know where he found a 3GB module, also a motherboard with 6 slots. Most of the DDR (that I know so far) are 2^n GB, so it can possible in sizes like 1GB (2^0), 2GB (2^1), 4GB (2^2)... you got the point, so maybe the problem is the TAG in the modules.

Intel Core i7 900-series CPUs on Intel X58 motherboards support triple-channel memory. I have no idea about the 3GB DIMMs.

My guesses:- the memory needs to be reseated into the slots- the memory needs to be rearranged into a specific order/slot usage (see motherboards manual)- check compatibility of the memory and your motherboard- the processor needs to be reseated (while the chance is very slim, one of the pins connecting the memory controller might not have proper contact and therefor causing one or more memory channels to fail)Last but not least the option no one wants to hear and/or can perform:test the memory in another systemtest other memory in this systemIt may just be some bad memory sticks.

One option I forgot: Memory speeds. The motherboard might use the wrong refresh rates for the memory which can cause all kind of weirdness.
