3.2 Processor
This product ships with the CPUs and a thermal solution installed. The thermal solution is custom and critical
for passive cooling. Cooling performance can greatly be affected if manipulation is not handled within
Kontron facility. Do not attempt any heat sink removal.
3.3 Memory
The AT8050 has 3 memory channels connected to the main CPU. There are 2 DIMMs per memory channels for a
total of 6. The AT8050 accepts DDR3, VLP(very low-profile) (0.72 inch; 18.29mm), 1.5V typical, registered,
ECC, x4 or x8 memory with up to 4 ranks per DIMM. The DDR3 memory channels run at 1066MHz with the 60W
Nehalem. A minimum memory size of 2 Gbyte is supported using a single DIMM. The maximum DDR3 SDRAM
size is 8GBytes per DIMM for a populated 48GBytes maximum. Memory modules shall have a validated
thermal solution (heatsink) and may necessitate 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.
Always populate DIMM0(J14, J16 & J18) first, then DIMM1(J13, J15 & J17) on each channel.
Only use validated memory with this product. Thermal issues or other problems may arise if you don’t use
recommended modules. At the time of publication of this user guide, the following memories have been
qualified and approved. As the memory market is volatile, this list is subject to change, please consult your
local technical support for an up to date list.
