Windows 7: windows 7 64bit only recognising 2 of my 6gb RAM

ok so i thought i could improve my speed by messing around with the ram settings after going into advanced performance options and virtual memory i messed around a bit and changed some settings and after reboot it said i only had 2gigs and it also says it in the BIOS please help and its my first time :P

Try a System Restore to a time prior to your fiddling with the settings.

" it also says it in the BIOS ". Doesn't sound like a Windows issue at all.

deanl2k11 doesn't mention what sort of motherboard he(?) has. For Asus boards, using the F5 function key while in the BIOS setup loads "optimized defaults". I hope that other makers have a similar way of getting the same function.

Go back into advanced options tic custom hit apply, then change it back to the default- let windows decide what`s best for my pc. Do the same with your virtual memory to get it back to where it was.

Reset you bios to the defaults (as others have advised.

i have done all above and it is still the same it is a acer aspire 57427 laptop and the mother board only give limited options but i did reset defaults and still the same

Dean,
Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

thanks for your cooperation,
