I recently purchased one of Intel's newest server boards; the S5500BC. This board has 8 DDR3 slots and a max of 32GB of RAM. I have maxed out one of these boards using (8) 4GB Kingston DDR3 1066 chips. The chips I used are on Kingstons list as certified with this board. The problem is the board only sees 16GB of RAM. The board has 4 slots on the end near the keyboard and 4 slots near the PCI slots. No matter what, the BIOS always shows the 4 slots near the PCI slots as empty. I have swapped the RAM from the PCI slots to the slots near the keyboard and I get the same result. Any ideas?
