Intel Desktop Boards D815EEA2, D815EPEA2, D815EFV, and D815EPFV Product Guide 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 PC100 Memory Modules...will operate at 100 MHz ...will operate at 100 MHz ...will operate at 100 MHz ...will operate at 100 MHz PC133 Memory Modules...will operate at 100 MHz ...will operate at 100 MHz ...will operate at 100 MHz ...will operate at 133 MHz (see note below) Processor Type (System Bus Frequency) Intel Celeron processor (66 MHz) Intel Celeron processor (100 MHz) Intel Pentium III processor (100 MHz) Intel Pentium III processor (133 MHz) ✏ 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.
