My Systemboard is HP-DX2400MT - IPIBL-LB (MoBo) and it supports Pentium Dual Core/Core 2 Duo/Core 2 Quad CPUs. I want to buy any same spec Xeon CPU and I want to know if if it is possible or there is a change that it will work without microcode update?

  • If I am not mistaken then an LGA771 literally has seven hundred seventy one connection points and LGA775 has seven hundred seventy five connection points. Please point to the documentation which you read that says these sockets and CPUs are interchangeable with nothing more than a "microcode" update. – MonkeyZeus Nov 30 '16 at 20:49
