2.4 System Memory support

The KTHM65/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 1066/1333/1600MT/s (PC3-8500/PC3-10600/PC3-12800)
(DDR3 1600 only supported by some i7 processors)
•
From 256MB and up to 2x 8GB. (up to 2x4GB tested)
Note: 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.
