X7DCT/X7DCT-10G User's Manual Processor and Heatsink Fan Installation Warning: When handling the processor package, avoid placing direct pressure on the label area of the fan. Notes: Always connect the power cord last and always remove it before adding, removing or changing any components. Make sure that you install the pro- cessor into the CPU socket before you install the CPU heatsink.
Loading the Processor into the Socket Align CPU Pin1 (the CPU corner marked with a triangle) against the socket corner that is marked with a triangle cutout. Align the CPU key that is the semi-circle cutout below a gold dot against the socket key, the notch on the same side of the triangle cutout on the socket.
X7DCT/X7DCT-10G User's Manual Installing the Heatsink CEK Heatsink Installation Do not apply any thermal grease to the heatsink or the CPU die; the required amount has already been applied. Place the heatsink on top of the CPU so that the four mounting holes are aligned with those on the retention mechanism.
Mounting the Motherboard in the Chassis All motherboards have standard mounting holes to fi t different types of chassis. Make sure that the locations of all the mounting holes for both motherboard and chassis match. Make sure that the metal standoffs click in or are screwed in tightly.
DIMM 1A and DIMM 1B, DIMM 2A and DIMM 2B, then DIMM 3A, DIMM 3B. Memory Support The X7DCT/X7DCT-10G supports up to 48 GB ECC Registered DDR2 667/533 in 6 DIMMs. Populating memory slots of the same bank with a pair of memory modules of the same size and same type will result in two-way Interleaved Memory which will improve memory performance.
