¥ Due to chipset limitation, Intel¨ Pentium¨ D 820 processors work only in single-core CPU mode.

¥Due to chipset limitation, dual-core processors cannot support the Intel¨ EIST, TM2, and C1E functions.

¥Install a chassis fan with at least a speed of 2400 rpm and 8 CFM

turnrate when using a dual-core CPU to ensure system stability. Overheating can permanently damage the system and/or CPU.

¥Install an additional chassis fan to ensure better air flow when overclocking.

¥Upon purchase of the motherboard, make sure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/ transit-related.

¥Keep the cap after installing the motherboard. ASUS will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA775 socket.

¥The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.
