Intel® Workstation Board WX58BP Product Guide Main Memory NOTE To be fully compliant with all applicable Intel ® SDRAM memory specifications, you must populate the board with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation. The Intel® Workstation Board WX58BP supports the following memory features:  Four 240-pin Double Data Rate 3 (DDR3) SDRAM Dual Inline Memory Module (DIMM) connectors with gold-plated contacts arranged in three channels  1333/1066/800 MHz DDR3 SDRAM interface  Support for single-, dual-, and triple-channel memory interleaving  Unbuffered, non-registered single or double-sided DIMMs with a voltage rating of less than 1.6 V. NOTE Using a DIMM with a voltage rating higher than 1.6 V may damage the processor.  Non-ECC or ECC DDR3 memory  Serial Presence Detect (SPD) memory only  Up to 16 GB maximum total system memory NOTE 32-bit operating systems are limited to a maximum of 4 GB of memory. The operating system reports less than 4 GB because of the memory used by add-in graphics cards.
