4GB ram installed but only 1 gb usable ???

Win & "Ultimate" I had 2 gb of ram installed.Comp was very slow to respond.So,I installed 4GB.PC seems faster now but,when I look at system properties,it says there is only 1 gb "usable" !!! I noticed that my system is running on 32 bits when my understanding is that this is supposed to be a 64 it system !!!.This is dell latitude D 630 that I bought refurbished.Oh...and before I installed the new ram,I was using in the low 90% of all my ram.Now,I'm using in the upper 80's !!

Have you consider the RAM is not slotted in properly, hence may not able to read the other 4GB RAM.

Do open the back cover to check the RAM 4GB is slotted and fitted nicely, not loose or easily removed.

Hello mate how did you find out it was 32bit? and what makes you think it is supposed to be 64bit? because if the seller told you it was 64bit and in fact it is 32bit then I would be getting my money back.

Personally I have doubts about refurbished gear because I often think it is so often easy for people to be ripped off. Go into the Control Panel > System and the first window should tell you what it is. Plus because of the problems the RAM usage is a worry and I am wondering what processes are running to chew it up like that. To see that see pic

Icit2lol-I found out it was 32 bit through the control panel.And,I think at one time I tried to DL something & I couldn't because I had to have a 64 bit OS.I somehow got it into my head that Win7 was a 64 bit OS.

You do not have to have 64 bit installed to use 4 GB. But windows will only use from about 3.25 to 3.75 GB`s on a 32 bit system.

My belief, If your cpu is 64 bit capable, then always install 64 bit. No matter what amount of memory you have in it at the time. You can always install more memory later.

Please post a shot of Resource Monitor showing the memory tab. Use the snipping tool then in your reply choose Go Advanced and click the small paperclip icon to attach the snip.

That will explain everything.

To open Resource Monitor.... Right click the taskbar>click Task manager>Performance>Resource Monitor>Memory

Addram-I cannot seem to post a snip of this.I am basically being told that the file is to big.And,I cannot find the "Go Advanced" icon Let's see if this works....

Eriic-the ram should be seated properly & snugly.My system is reading both 2gb sticks.

and according to the HP data sheet thats a 64bit 8GB max machine?
run this see whats there, hwinfo
