Hi all my name is maggie and im tearing my hear out trying to put this right
about 3/4 yrs ago i purchased a new desktop from ebay with no os
so i ran xp for around a year then put windows 7 ultimate 64-bit on it anyway:-
i have just fitted after emailing crucil memory and using their scan and posting my report of my system info on motherboard bios chipset etc
CT2KIT25664AA800 4GB kit (2GBx2), 240-pin DIMM Upgrade for a ASUS P5VD2-VM SE System
xp on one sata hard drive is showing 3gig and 7 is showing 2.50gig(2.37usable)
i have updated my chipset and bios with no evail ( they could be the wrong updates who knows)
have gone into msconfig bios advanced and both ticked and unticked max memory rebooting between the adjustments with no evail
ASUS P5VD2-VM SE motherboard CHIPSET P4M900 BUS TYPE INTEL GTL+
BIOS AMI VERSION 0506 12/17/0
PROCESSOR INTEL(R) D CPU 3.00GHZ 3.00GHZ
i have a full everest report if you would like to see it as that shows in one place that i have 4gig installed yet in the dimmo and dimm1 its only show as 1 x 2 gig plus 1 x 512 only prob is that the report is rather large and im not sure if it will all fit in
i think you have the 32bit (x86)versions installed
both versions wil not find your 4 gb fully its a 32 bit os limmitation
is there an on board video on your board ? cause it will take some memory for the card (usualy reserved in bios)
can you try a pci-e videocard?
Maggie, there's part "Intel® 64 : no". so the processor doesn't support 64-bit instructions only 32-bit. So yes, maybe he's right. The 4gb memory and above is 32-bit limitation. The amount of detected memory is going to be always ~3gb. So it could be you're using 32-bit version.
To check it out, click on the Start button (Windows logo), right-click on My Computer, Properties.
What he's speaking is that your memory at Win 7 is chipped by 512 Mb, and that's probably is shared memory with your VGA.
