3.3 System Memory support

The 886LCD/ATX(GV) and 886LCD/ATXU(GV) boards have two onboard DIMM sockets and support the
following memory features:
•
2.5V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
•
Supports up to two single-sided and/or double-sided DIMMs (four rows populated) with unbuffered
PC1600/PC2100 DDR-SDRAM
•
Supports 64 Mbit, 128 Mbit, 256 Mbit and 512 Mbit technologies for x8 and x16 width devices.
•
Maximum of 2 Gbytes system memory by using 512 Mbit technology devices (double sided)
•
Supports 200 MHz and 266 MHz DDR devices
•
64-bit data interface
•
ECC not supported with the Intel 845GV chipset
The installed DDR SDRAM 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.
In general DDR SDRAM with higher speeds than 266MHz may be used (e.g. 333MHz or 400MHz), but it is
recommended to run a qualification test before use or to use Kontron Technology validated DDR SDRAM.
