32bit windows can only recognise about 3.5GB RAM; another 1GB may be given over to onboard graphics.

When booting the PC, do you see a message like "press tab to see post" or the like? IF so, does it tell you how much RAM installed?

Hi MrNewName

Thanks for your post

I am running 64bit windows 7 ultimate

I hit the tab key while booting and it said that i had 2432MB installed

I then swapped the 2 x 2gig sticks around in the slots and did it again and it still said the same

many thanks

Your second stick of ram is just 512Mb.

Post the serial codes on both sticks of ram.

It might be possible that your motherboard can't support 4gb of memory , what make and model is it ?

Sorry , just read specs again , I see it does support 4gb , suggesting that the memory controller may be faulty , or your motherboard is fussy about what make of memory you are putting in . Do you get the same result from dram slot 2 each time it is tested ?

Looks as though they aren't compatible to run side by side.

Hi folks

I have contacted crucial memory scanned my comp with their scanner aslo emailed and told them i wanted the fastest memory for my motherboard so they sent me 2 x 2gig DDR2-800 (400 MHz) Micron 16HTF25664AY-800J1

so well pleased with the fast service they supplies i intalled my new sticks

BUT still not reading correct amount my scan shows i have the sticks but not my system it still says 2.50gig(2.37usable)

i have retried msconfig advanced ticked also unticked max memory

im tearing my hair out here because i like things to run smoothly and i dont think my comp is running as good as it should do

any ideas please
