Memory has only 2Gb usable

[Ravenhalllow]

Hi everyone I just transported my rig back from collage and when i set it back up i noticed that i only had 2 Gb of ram being used. I have flashed bios and that didn't fix the problem. I have also tried to run a system repair for windows 7 and that came up with a Error code = 0x490 but couldn't find a repair on it for windows 7. I don't know if this is the problem or if there are other issues going on. I did find that my 4 Gbs are saved for Hardware reserved resource Monitor. Any help will be greatly appreciated.

Not sure what you're getting at here but

have your tried uninstalling and reinstalling the Ram..it may have been jarred during the shift and not be seated properly.

Hi Ravenhallow,

Please run SFC, just follow the directions and report back. How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7

hi there
there are a few settings to look at that may establish your problem

OPEN SYSTEM CONFIGURATION

1> press windows key + R
2> type msconfig
3> click OK
4> on the top tabs in system configuration click BOOT
5> in boot advanced options check the MAXIMUM MEMORY BOX IS UN-TICKED (as in the snapshot below)
6> click ok. if windows asks for you to restart, restart pc.

Welcome RavenHalllow

Can you give us a screen snip of your memory with CPU-Z of the Memory tab & SPD tab for each memory slot ?

 

[brianzion]

also you can have a look at what windows has allocated to your ram using RESOURCE MONITOR (as in pic below) if you could post back the results this will help

1> windows key + r
2> copy and paste (or type) %windir%\system32\perfmon.exe -res
3> click MEMORY in the top tabs
4> when you mouse over the figure's you get a explanation if you are unsure

great advice docbrown as always is the op worth checking memory mapping? (The usable memory may be less than the installed memory on Windows 7-based computers >> http://support.microsoft.com/kb/978610)

x58 chipset, start here,

Asus X58 + 6/12GB memory overclocking - detecting less memory than installed - i4memory.com - different look at memory

Seeing as you just finished transporting it, #8 may apply if the heatsink shifted at all while moving it.

 

[Ravenhalllow]

here are the screenshots for cpu-z

 

[DocBrown]

Thanks for the snips of CPU-Z. I am wondering why the first snip shows it is recognizing the memory as single channel ? Did your MB manual tell which slots to place triple channel memory in ? One of my Gigabyte MBs uses 1,2,3 for 6GB triple channel.

 

[Ravenhalllow]

Then manual says the the first banks for using three dimms are the usual 2, 4 and 6 which on this board they are 1, 3, and 5. doens't start up if the dimms are not placed in this manner.

 

[Ravenhalllow]

that is true tho i don't know why it says it there in the bios it says 6 channel.

 

[Ravenhalllow]

Yeah i don't know why it says that. In the bios just to write down what i have it set to.

6-way channel
I don't remember if i posed it already, but I have flashed the bios for this mother board a couple weeks ago. I am backing up the system on a separate Hard drive that just came in.

System scan just finished and it says that windows resource protection didn't find any integrity Violations.

?It says to use 2,4, and 6?

 

[Ravenhalllow]

No, we are using slots 1, 3, and 5 on this mobo. We have just put in another 3 banks of ram for a grand total of 12Gbs, but now its using only 4Gbs and 8Gbs are now reserved for Hardware. So now we have to dimm banks that are running and having windows use it.

 

[Britton30]

Go to start and type msconfig, click the Boot tab and Advanced Options. Make sure the Maximum Memory is UNchecked. Click OK, OK, if you had to change anything, a restart will be needed.

Did it show all available memory before you transported the system? If so, then we're wasting your time with software suggestions. One of two things happened. Either some of the memory came loose and needs to be reseated, or your system was damaged somehow, possibly through a static shock or something of that nature.

 

[Ravenhalllow]

That is the weirdest part and most extreme opt. we are just trying all options before i order another mobo. I have transported rigs all over for lan parties i can't believe that this happened from transporting it home from collage. I will check out the MSconfig shortly on the rig and get back to u afterwards. thanks far all your inputs on this matter.

Then your computer is recognizing all the RAM, but is diverting it elsewhere. Make sure that the proper boxes are unchecked and checked, and it should solve your problem.
