Note
: Sufficient cooling must be applied to the CPU in order to
remove the effect as listed in above table (Thermal Guideline). The
sufficient cooling is also depending on the maximum (worst-case)
ambient operating temperature and the actual load of processor.
The Kontron PN 1044-9447 is “Active Cooler for KTQM67/KTQM77”
capable of being used for processors (fully loaded) having Thermal
Guideline up to 45W @ 60ºC ambient temperature.
All the processors in the list above, inclusive the Celeron processor, are supporting the Enhanced Intel®
SpeedStep® which is improved SpeedStep technology for faster transition between voltage (power
saving states) and frequency states with the result of improved power/performance balance.
Intel® Turbo Boost Technology 2.0 is supported by i5 and i7, as indicated in above list of processors,
and is enabling overclocking of all cores, when operated within the limits of thermal design power,
temperature and current.
Intel® vPro Technology is supported by some of the i5 and i7 (not by Core i3).
2.4 System Memory support
The KTQM77/mITX has two DDR3 SODIMM sockets. The sockets support the following memory
features:
•
1.5V (only) 204-pin DDR3 SODIMM with gold-plated contacts
•
Single/dual rank unbuffered DDR3 1333/1600MT/s (PC3-10600/PC3-12800)
•
From 256MB and up to 2x 8GB. (up to 2x4GB tested)
Notes: Less than 4GB displayed in System Properties using 32bit OS
(Shared Video Memory/PCI resources is subtracted)
•
SPD timings supported
•
ECC not supported (PGA processors do not support ECC)
The installed DDR3 SODIMM should support the Serial Presence Detect (SPD) data structure. This
allows the BIOS to read and configure the memory controller for optimal performance. If non-SPD
memory is used, the BIOS will attempt to configure the memory settings, but performance and reliability
may be impacted.
Memory Operating Frequencies
Regardless of the SODIMM type used, the memory frequency will either be equal to or less than the
processor system bus frequency. For example, if DDR3 1600 memory is used with a 1333 MHz system
bus frequency processor, the memory clock will operate at 666 MHz. The table below lists the resulting
operating memory frequencies based on the combination of SODIMMs and processors.
