CAUTION
Before installing or removing memory, make sure that AC power is disconnected by unplugging
the power cord from the computer. Failure to do so could damage the memory and the board.
NOTE
Remove the AGP video card before installing or upgrading memory to avoid interference with the
memory retention mechanism.
NOTE
To be fully compliant with all applicable Intel
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
The D815EFV and D815EPFV boards both have three DIMM sockets and support the following
memory features:

At boot, the BIOS displays a message indicating that any installed memory above 512 MB has not
been initialized.
NOTE
3.3 V (only) 168-pin SDRAM DIMMs with gold-plated contacts
Unbuffered single-sided or double-sided DIMMs
Maximum total system memory: 512 MB; minimum total system memory: 64 MB
133 MHz SDRAM or 100 MHz SDRAM
Serial Presence Detect (SPD) and non-SPD memory
Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
Suspend to RAM
Non-SPD DIMMs will always revert to a 100 MHz with 3-3-3 timing SDRAM bus.
Mixing Non-SPD DIMMs with SPD DIMMs will always revert to a 100 MHz with 3-3-3
timing SDRAM bus.
The BIOS will not initialize installed memory above 512 MB.
Mixed memory speed configurations (133 and 100 MHz) will default to 100 MHz.
133 MHz SDRAM operation requires a 133 MHz system bus frequency processor.
The board should be populated with no more than four rows of 133 MHz SDRAM (two
double-sided or one double-sided plus two single-sided DIMMs).
100 MHz SDRAM may be populated with six rows of SDRAM (three double-sided DIMMs).
