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)

The supported 2

Generation Core i5 support 1066/1333 MT/s

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 Serial Presence Detect (SPD) data structure. This allows the

BIOS to 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.

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.
