Motherboard Installation
Memory Installation
Refer to the DDR3 memory section in Chapter 1 of this manual for detailed information on the proper
memory modules to be used on the motherboard.
There are a number of PC3-10600, PC3-8500 and PC3-6400 DDR3 DIMMs available for use on the
motherboard from a number of different sources. Available memory capacity and module construction
varies, but the same basic DDR3 DIMM characteristics must be present on the modules you select. These
characteristics are:
•
ECC-registered (72-bit) DDR3 memory
•
Gold-plated DIMM contacts
•
240-pin DDR3 DIMMs
Trenton has validated the performance of a number of different PC3-10600, DDR3 DIMMs for use on the
motherboard:

The memory market is constantly changing. Check with Trenton to learn the latest in validated memory
availability for the motherboard.
The same basic memory installation procedure listed below should be followed regardless of the memory
type used on the motherboard.
1. Populate the memory channels starting with the DIMM socket farthest from the CPU. Work you
way toward the processor populating the DIMM sockets labeled with an “A” first followed by the
“B” labeled sockets.
2. The chart and diagram below will help guide your memory installation:

3. Ensure the DIMM release tabs of the sockets are open before
inserting a memory module.
4. Insert each DIMM into each socket observing that the modules
registration notch is oriented correctly.
5. Press down on the DIMM until the module release tabs snap
into place.
6. Repeat this process for all remaining DIMMs.
7. Pushing open the socket’s release tabs enables a module
to be easily removed from its DIMM socket.
