Installed 2GB RAM, Vista only sees 1GB, but BIOS sees 2GB

Inspiron E1505 with 1GB RAM (2 x 512GB).  Vista Control Panel/System shows 1GB.  Upgraded to 2GB (2 x 1GB). After upgrade BIOS shows 2GB "available", 1GB "installed", with no options to change in BIOS.  POST passes memory test at 2GB, but Vista Home 32 bit Control Panel /System still shows 1GB?

Any ideas howto get BIOS to see 2GB and then I supposed Vista will?

Depending on the exact configuration of yoru E1505 some of your physical memory may be used as video memory. However I have never seen an onboard video card use over 512MB of physical memory so this may not be the issue. Also make sure you have SP1 for Vista installed as the non-sp version may not report your memory correctly.
I hope this helps. Good luck.

Interesting.   The issue is NOT video memory (max for a 945GM is 224MB, so it can't be using 1GB);  and it's not relevant whether you have SP1 or not ... that only changes how memory is reported if you have more memory than can be assigned addresses within the 4GB address space [clearly not the case here].

Does the BIOS have an "install mode" ??   If so, be sure it's not enabled -- this generally limits the amount of memory that's enumerated to the OS.   If not, look very carefully at the memory options in the BIOS => the fact that the BIOS shows only 1GB "installed" clearly indicates this is a BIOS issue -- resolve that and Vista will use the memory just fine :-)

I agree, also check the video aperture settings if any.


I hope this helps !

GaryCase,
Yes I agree it is a BIOS issue, fix that and likely Vista will follow.  I did not see an "install mode" in the BIOS, but I will look again when I get my hands on the LT next week.  The memory portiion of the BIOS had "unmodifilable" parameters (read only).  Other than "install mode", what else should I look for?
Thx

Why not just leave the question as unresolved and not fixed... until it is fixed? Part of the usefulness of a site like this is "what fixed it for others might fix it for me" and if you leave it as a partial answer it won't help the future people and we will not totally know if your problem was fixed.

It's possible one of the sticks has a problem and the bios is disabling it, try the sticks 1 at a time(when you get the system back) and see how it behaves.

you can also run memtest86+ on the ram sticks, and see what they report

When you start the PC and get into the BIOS, is there no "Save Changes" option?

Any updates on if the solution worked? If not what have you tried since you last wrote?

Problem was solved when the person who had the problem was no longer interested in a solution.  Thanks for your help.
