DX38BT Technical Product Specification
Intel Desktop Board DX38BT Technical Product Specification
16
1.5 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.5 V with option to raise voltage to support higher performance DDR3 SDRAM
DIMMs
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
• 8 GB maximum total system memory. Refer to Section 2.1.1 on page 41 for
i
nformation on the total amount of addressable memory.
• Minimum total system memory: 256 MB
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR3 1333, DDR3 1066, and DDR3 800 MHz SDRAM DIMMs
NOTES
• Remove the video card in the Primary PCI Express x16 before installing or
upgrading memory to avoid interference with the memory retention mechanism.
• 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.

Notes:
1. In the second column, “DS” refers to double-sided memory modules (containing two rows of SDRAM)
and “SS” refers to single-sided memory modules (containing one row of SDRAM).
2. In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.
