Memory
The KTC5520/EATX has 6 memory channels, 3 for each CPU. There are 2 DIMMs per memory channels for a
total of 12 DDR3 memory sockets. The KTC5520/EATX accepts DDR3, 1.5V typical, registered, ECC, x4 or x8
memory with up to 4 ranks per DIMM. The DDR3 memory channels run at 800MHz, 1066MHz and 1333MHz
depending on your CPUs. The maximum DDR3 SDRAM size is 8GBytes per DIMM for a populated 96 gigabytes
maximum on the KTC5520/EATX. Memory modules shall have a validated thermal solution (heatsink) and
may require a certain class of chassis. It is recommended that modules have thermal sensors for accurate
temperature monitoring and to throttle the memory interface in case of overheating. Memory can perform
double refresh rate to get higher maximum operating temperature.
The content of the SDRAM is not affected by a warm reset.
A minimum memory size of 1 Gbyte is supported using a single DIMM. A maximum memory size of 96 Gbyte is
supported using 8 Gbyte technology DIMM in each slot.
Always populate Slot 0 first on each channel.
WARNING
Heat sinks might have sharp hedges.
Note:
Power supply must be compliant to the SSI specification and it is recommended to use a 1000W
power supply.
