Warning W2506 - If the system does not support memory error correction (e.g. using ECC) if an error is detected the system will stop. A system that supports correction will attempt to correct the error and continue. A server should use error-correcting memory always.
Fix: Use ECC (1-bit error correction) memory. Make sure the chipset supports ECC memory. Some chipsets support ECC up to a certain memory bus speed or FSB.
