Windows not recognizing extra memory

Hello,

I have a Dell Latitude D610 running Windows XP Pro SP2. I installed 2 1 GB DIMMS of DDR2 memory to replace my existing 2 of 512. Machine is running fine, but when I right click my computer and hit properties, it says I only have a gig of RAM.

Dell specs say this machine supports up to 2 gigs of ram (1 per slot). Any idea why Windows doesn't see it?

Thanks!

 

Just a quick overview ..
You had 2 x 512 - you removed both.
You then installed 2x 1GB.
How did you choose memory sticks? Were they verified via Dell site or purchased site for compatibility for make/model computer??? (please answer this question) - If yes, continue.
Since (1) stick is recognized do one of the following ...

One stick is not properly seated.
Shut down computer, remove both, reinstall both. Be sure white tabs clicks/close when seated.
If no luck ...

One stick is bad.
Shut computer off.
Pull (1) stick.
Reboot computer, if reports properly (allow for shared memory if applicable /video card).
REPEAT above step. Exchanging sticks.
For these two test, always use the SAME ram bank.
Let us know how test works out.

If you have a failure with either stick, repeat test in DIFFERENT ram bank. Test each stick individual.

Let us know how test works out.

 

Thanks, turned out to be a hasty post. The sticks were qualified via compatibility website. I switched the DIMMS and it worked fine. I'm guessing it was probably not seated properly. Laptop DIMMS not the best design!

 

Nice if all fixes were that easy.
Good work. Thanks for reporting back.
