I've got two identical intel CPUs in an Asus board with one stick of ram each. On power up, board immediately throws code 19 ("SB initialize before installed memory"). I've tested each CPU individually, as well as each stick of ram. When using a single cpu, the system boots fine with either one or two sticks of ram installed. The only time I have issues is when I install the second CPU. Am I missing something critical to dual-CPU builds that isn't done in single-CPU builds?

The 1620V4 only supports single CPU configurations: https://www.intel.com/content/www/us/en/products/sku/92991/intel-xeon-processor-e51620-v4-10m-cache-3-50-ghz/specifications.html
