I'm using 2 sticks of 512MB Samsung RAM.
This page has a table at the bottom that lists qualified RAM. The 128 and 256 Samsung RAM is listed, but the 512 is not.
I'm using the most up to date BIOS, version 1015.
I'm going to install Windows 2000 on this box now and see what happens.
I don't know if the card is sharing an interrupt. Where can I check? I have the G4 in the AGP slot and I have a modem in the bottom PCI slot, and that's it as far as cards go in this box.
My mobo is also the non-RAID version.
