Supported System Bus Frequency And Memory Speed Combinations; Supported Memory Configurations - Intel BOXD915GVWBL - Desktop Board D915GVWBL Manual

Intel Desktop Board D915GVWB Technical Product Specification
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR 400 MHz and DDR 333 MHz SDRAM DIMMs
Table 4 lists the supported system bus frequency and memory speed combinations.
Table 4.

Supported System Bus Frequency and Memory Speed Combinations

To use this type of DIMM...
DDR 400
DDR 333 (Note)
Note: When using an 800 MHz system bus frequency processor, DDR 333 memory is clocked at 320 MHz. This minimizes
system latencies to optimize system throughput.
NOTES
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 5 lists the supported DIMM configurations.

Note: 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).
INTEGRATOR'S NOTE
It is possible to install four 2048 MB (2 GB) modules for a total of 8 GB of system memory,
however, only 4 GB of address space is available. Refer to Section 2.2.1, on page 39 for additional
information on available memory.
