Vista has alzheimers

Feb 18, 2007 10:17PM PST

I have installed 4gb of PC6400 memory, in order to handle Vista better. Only 3324 show up in System and limits my Windows experience to 5.1.

I have checked the memory chips out with Memtest and all of it shows up in Belarc advisor. Why is my 700+/- gb invisible?

Xp 32 bit has an issue
Feb 19, 2007 4:25AM PST

recognizing memory over 3 gigs of RAM. (or is it 2?)

Provided that your MB will support 4 gigs of RAM Vista may have the same issue as XP.

Just a thought till someone can confirm.

Found this on Kingston Memory website
Mar 5, 2007 2:44AM PST

I just upgraded my Windows Vista 32-bit from 2GB to 4GB and had exactly the same issue. I used Kingston technology RAM and found this on their website: http://www.kingston.com/windowsvista/vista_faq.asp

Footnote ** under the first table reads: "Approximately 3.3GB addressable memory. Vista reserves upper memory space for hardware usage."

I read in another forum that the 64-bit version can recognize 4GB correctly.
