Question

Iron

The dual-processor motherboard intel s2600cp, of course, is no longer relevant, but you can find a new one in stock, I bought into the good price / quality ratio of the lga2011 platform. Intel is positioned for workstations, too. There is a pcie x16 wired to x8 and six x8, all gen.3. Tried three different elderly video cards, two of them with separate power supply, does not start. The BIOS gives three long beeps and does not start, it starts with onboard vga. Maybe someone came across, I will be grateful for advice.
