Bios update difficulties

[Racing96mustang]

Hello Paul,

I happen to have an old, and nice, HP DV8408US with Intel CPU.  I had upgraded the machine to an SSD boot drive, Windows 7 x64, and a T7600 2.33 Ghz Core2 Duo CPU.  I always kept the BIOS up to date but never found one supporting the full 4GB RAM I had installed.  It shows 3GB instead, even with a 64-bit OS.

Did you know of another BIOS that maybe fixed that issue?  Could you point me to it by FTP link?  I know HP doesn't offer a friendly site link anymore due to the age of the machine.

Thanks!

Hi:

I believe the last BIOS update for your notebook's model series was F.24.

It was meant to be run in Windows Vista, so I don't know what the risk would be if you ran it in W7.

There is no longer any information on the file or what it fixes or enhances.

Windows 32 or 64 bit on any Intel 945 chipset based platform will never show the full 4 GB memory utilization.

The max I have ever encountered was 3.25 GB.

Most of the memory goes to the graphics' shared system memory.

The only time you will find close to the 4 GB utilization on a 64 bit system, is if the PC supports 8 GB of memory, which yours does not.
