I have Windows Xp PRO Service pack 2, motherboard Gigabyte GA-8S661FXM-775 and I had 512Mb di Ram Kingston PC3200 DDr 400, then I added 512Mb of Transcend PC3200 ddr 400.
If i go in Control Panel -> System I can only see 480 insted of 1024
But in CPU-Z and Everest I can see the two slots: one with the Kingston memory and one with the Trandscend one, with a total of 1024Mb.
I tried to reset the BIOS, but it didn't work. They aren't damaged because i tried them individuallu and they worked.
In my BIOS there aren't any refer to the RAM, so i can't modifythis setting with the BIOS.
