64 bit os or 32bit OS? if you have 32bit you have to upgrade to windows 7 64bit to use over 4gb of ram

MS Windows 7 Ultimate 64-bit SP1

Right click on Computer and go to Properties. Do you see 64 bit operating system below the installed memory like in the picture below?

If it is so what do you see in Memory is it 8GB (4GB usable) or 8GB?

Windos 7 Home Premiuim 64 bit


I am having the same issue. I have an Acer Aspire 5552 which came with 4gb.I upgraded to 8gb and have tried all the solutions on this and a few other forums but no joy. I still get the message "Installed memory 8.00gb (3.74 useable).

I have a 64bit operating system.

Can anyone make any suggestions?

(ps Would have been nice if the OP mentioned how he/she fixed their poblem.)

Tip: Always better to post a new thread. The only people who will see your thread here are the ones that responded to the original post.

What have you done so far?
Did you uncheck the box as ZigZag suggested?
Did you reinstall the RAM module to be sure it is seated correctly as I suggested?

Thanks for that.

I have resolved the issue by rolling back my bios to the earliest and also blowing out the memory ports

Take care

Like the title says, this issue popped up a few days ago. I've done the old "uncheck maximum memory" and that did nothing. I also already opened up my computer and made sure there was no dust on the ram and that the sticks were properly installed. I don't know my way around a BIOS and i'm afraid to...
