Windows not utilizing all 12 gigs of ram

post #1 of 9
Thread Starter 
I recently purchased another 6 gigs of RAM for my system to come out to 12 gigs.
DDR3 PC3-12800 1600MHz 1.65v
My older ram is identical besides the look...

My motherboard is EVGA X58 SLI-LE and the cpu is i7 920

My OS is windows 7 ultimate 64 bit

After i installed the ram and booted up i noticed it wasnt using all of it, and surely after going to system in control panel it showed 12 gigs installed (8 gigs usable)

After running ram test it all checks out 100% and i am currently running on the new sticks with the old ones out.

What can i do to have my system recognize all 12?

we are a little short on info

fill out your RIG here

Edit: Your system does recognize all 12 gigs, but I don't know yet as to why it says you can only use 8 gigs

ok man try this;
open an elevated command prompt (type cmd in the search box, right click the restult and choose 'Run As Administrator')

type: msconfig . This brings up the configuration utility.

Click the Boot tab, and then click the Advanced Options button.

In that window, there is a setting for Maximum Memory - Make sure the checkbox for it is clear (not checked), then reboot your computer. hope this works, I just remembered this lol

alrighty....

i started at step one took out all ram put the new sticks in the place of the old ones and the old ones in the empty slots...

went into bios reset ALL settings.
made sure all the voltages are configured properly as well as the frequency.

booted up, checked ram....12 installed...12 utilized.

I dont get it. 3rd times the charm? i did this 2 times already and both gave me the problem listed above, now it seemingly solved itself.

The ram could not have been seated 100% correctly in their slots. Glad it's fixed now though! thumb.gif
