Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM... The processor's system bus frequency must be ...
DDR400
DDR333
*When using an 800MHz system bus frequency processor, DDR333 memory is clocked at 320MHz.
This minimizes system latencies to optimize system throughput.
NOTE:
While using ECC type memory, it will take longer time to post. Due to the manner in which it
counts the memory and has to write zero's to every bit of the stick before progressing through
the POST.
2.8 – Memory Installation Procedure
When installing memory modules, make sure the modules align properly with the memory
socket. There should be keys (small indents) on your memory modules that fit according to the
keys in the memory socket. DDR modules and sockets have only one key, which is slightly
near the center of the module/socket. The method of installing memory modules is detailed in
the following diagrams.
Once the memory modules are firmly seated in the socket, two clamps on either side will close
and secure the module into the socket.
manually.
To remove the memory module, simply push the clamps outwards until the memory module
pops up. Then simply remove the module.
TIP: When installing memory, a module may require a considerable amount of force to seat
properly, although this is very rare. To avoid bending and damaging your motherboard, place
it on its anti-static bag and onto a flat surface, and then proceed with memory installation.
Note: You MUST unplug the power connector to the motherboard before performing system
hardware changes, to avoid damaging the board or expansion device
