Memory
• Up to two 184-pin Double Data Rate (DDR) SDRAM Dual Inline Memory
Modules (DIMMs) with gold-plated contacts. Supported memory
configuration are:
— DDR333: to run DDR333 memory at full speed requires an Intel
Pentium 4 processor with 533 MHz front side bus frequency (FSB)
— DDR333 memory will run only at DDR266 speeds when using a
processor with 400 MHz FSB
— DDR266: requires an Intel Pentium 4 processor with
533/400 MHz FSB, or Intel Celeron processor with 400 MHz FSB
— DDR200: requires an Intel Pentium 4 or Intel Celeron processor with
400 MHz FSB
• Unbuffered and non-registered single or double-sided DIMMs
• Serial Presence Detect (SPD) memory only
• Non-ECC RAM (ECC memory will run in non-ECC mode)
• 2.5 V memory
NOTE: Desktop Board D845PESV has been designed to support DIMMs based on
512 Mbit technology up to 2 GB, but this technology has not been validated on this Intel
®
desktop board. For more information about the latest list of tested memory, refer to the
