Ram compatibility with i440BX in Toshiba Satellite 4090XCDT
Posted: Wed Aug 03, 2005 11:01 am
My Toshiba Satellite 4090XCDT is severely memory challenged even with the maximum manufacturers specified memory installed, this being 64MB internal + 128MB sodimm = 192MB total.
Since the i440BX chipset in this notebook is capable of handling MUCH more memory ie 4 x 256MB, I've tried installing a number of different types of 256MB sodimms, including a 16 chip low density module with 4K refresh, but the laptop won't boot.
Can anyone advise me here? Is the BIOS possibly limiting the maximum memory to 192MB....if so, do 3rd party patched BIOSes exist to increase this to 64+256=320MB ? I'm currently running Toshiba's latest BIOS V8.2.
I've consulted the "i440BX RAM Compatibility FAQ" but still I'm stuck at 192MB ! Thanks for any light you can throw on this issue.
Cheers...Dale
