Q57 Express Chipset
The Intel Q57 Express Chipset consisting of the Intel Q57 Platform Controller Hub
(PCH) provides interfaces to the processor and the USB, SATA, LPC, audio, network,
display, Conventional PCI, and PCI Express x1 interfaces. The PCH is a centralized
controller for the board’s I/O paths.

1.6 System Memory
The board has four DIMM sockets and supports the following memory features:
• Two independent memory channels with interleaved mode support
• Support for non-ECC, unbuffered, single-sided or double-sided DIMMs with x8
organization
• Support for unbuffered ECC memory when used with an Intel Xeon processor
3400 series
• 16 GB maximum total system memory (with 2 Gb memory technology). Refer to
Section 2.1.1 on page 41 for information on the total amount of addressable
memory.
• Minimum total system memory: 1 GB using 1 Gb x8 module
• Serial Presence Detect
• DDR3 1333 MHz and DDR3 1066 MHz SDRAM DIMMs
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the DIMMs may not function under the
determined frequency.
Table 3 lists the supported DIMM configurations.
