asked on Why does my computer say 24 GB ram 16 GB usable?
Windows 7 professional 64 bit
Gigabyte GA EX58-UD5
i7CPU 920@2.67Ghz 2.66 Ghz
Gskill Ripjaw f3-8500CL7S-4gbrl DDR3-1066 PC-8500 4gbx1 spd cl7-7-7-1 8 1.5v
24 gig ram 6x4
Nvidia Quadro FX4800
Recently my computer shows I only have 16 GB ram with 24 GB installed. I was forced to reinstall windows from another problem but I never noticed this prior to that installation. Is there something I need to do to make it "see" the other ram?
Thank you,
Arti

Try going into msconfig -> boot -> advanced options. And increasing the maximum memory and then running a reboot.

@jcimarron,
Nice article! Thanks for posting. Regards, Joe

joewinograd--Well, thank you.
Nevermind that is the first thing dkrollCTN suggested.
ScottCha--Actually the suggestion I made is to "clear" (reduce to 0) the Maximum Memory box, rather than to increase it as suggested by dkrollCTN.

I may have found my problem if my failing memory in my head stirs. When I built the computer I bought and still have on disc windows 7 64 Home. 3 yrs ago I found out it wouldn't let me run 24 RAM installed. I went online and upgraded to Professional. I have no idea where the key is. Something tells me I have to purchase it again.
When you look at the actual System Properties dialog, does it say Home or Pro?
Run msinfo32. The first entry in System Summary is OS Name. Is it Home or Pro?
@BillBach,
Sorry about that...had a previous version of the page before your post sitting there. Regards, Joe

It is home. 64 bit
OK, so that's the problem! 16GB max on Home.
Actually, 16GB max on Home Premium...just 8GB on Home Basic.
If only we had a chart that showed all that... ;-)
:)
Yikes! Stepped on you twice in the same question...I promise it won't happen again. Btw, that's a great chart...excellent reason for getting W7 Pro instead of Home Premium.

Yes, yes,,... My error. Glad I have you experts for the last 4 yrs. Thank you for all your help. May I just award to Billbach who initially made the suggestion?
Works for me! Although I really like the article that jcimarron posted.
