Intel Desktop Boards D815EEA2, D815EPEA2, D815EFV, and D815EPFV Product Guide
16
• Unbuffered single or double-sided DIMMs
• Serial Presence Detect (SPD) memory
• Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
• 3.3 V memory (only)
• Suspend to RAM support
• Mixed speed DIMM configuration will default to the slowest speed DIMM installed.
The board supports the processor and memory module combinations shown in Table 5.
Table 5. Processor and Memory Module Combinations
Processor Type (System Bus Frequency) PC100 Memory Modules… PC133 Memory Modules…
Intel Celeron processor (66 MHz) …will operate at 100 MHz …will operate at 100 MHz
Intel Celeron processor (100 MHz) …will operate at 100 MHz
…will operate at 100 MHz
Intel Pentium III processor (100 MHz) …will operate at 100 MHz …will operate at 100 MHz
Intel Pentium III processor (133 MHz) …will operate at 100 MHz …will operate at 133 MHz
(see note below)

NOTES
100 MHz system bus frequency processors will support 133 MHz memory; however, the memory
will operate at 100 MHz.
For 133 MHz operation, only four sides of memory can be used; two double sided DIMMs, or one
double sided DIMM and two single sided DIMMs. If more than four sides are used, the memory
will only run at 100 MHz.
