Windows 7: Memory has only 2Gb usable

Ravenhalllow · 26 May 2011

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 ?

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.

here are the screenshots for cpu-z

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.
