2.4 System Memory support

The KTQ77/FLEX has four DDR3 UDIMM sockets. The sockets support the following memory features:
• 4x DDR3 1.5V UDIMM 240-pin
• Dual-channel with 2 UDIMM per channel
• Single/dual rank unbuffered 1333/1600MT/s (PC3-10600/PC3-12800)
nd
The supported 2
From 1GB and up to 4x 8GB.
Note: Less than 4GB displayed in System Properties using 32bit OS
(Shared Video Memory/PCI resources is subtracted)
• SPD timings supported
• ECC not supported
The installed DDR3 DIMM 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 DIMM 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 DIMMs and processors.

1052-5601 8GB DDR3 1600
In order to support Intel ® AMT (Management Engine) SLOT A0 must always be populated. In case of
using more than a single DIMM it is recommended to populate A0 + B0 first.
