This item is used to enable/disable provision of DRAM timing by SPD device. The Serial CMOS Setup Utility - Copyright (C) 1985-2005, American Megatrends, Inc. DRAM Timing Configuration DRAM Timing Configuration Help Item Memory Speed Mode [ Auto] Options DRAM Timing Mode [Auto] Auto Limit Manual 3 Move Enter:Select +/-/:Value F10:Save ESC:Exit F1:General Help F9:Optimized Defaults Presence Detect (SPD) device is a small EEPROM chip, mounted on a DDR2 memory module. It contains important information about the module's speed, size, addressing mode and various other parameters, so that the motherboard memory controller (chipset) can better access the memory device. Select [Auto] for SPD enable mode. Select [Limit], the DRAM speed will not exceed the specified value listed in the "Memory Speed Adjust " item. If SPD value is faster than "Memory Speed Adjust " value, it will run at the specified "Memory Speed Adjust " speed. Otherwise, SPD value is selected. Select [Manual], then DRAM speed is manually selected according to the set value of "Memory Speed Adjust ". ► Memory Speed Adjust This item will appear only when the "Memory Speed Mode" is set to [Limit] or [Manual]. The available settings are: [400MHz], [533MHz], [667MHz], [800MHz], [1066MHz]. [1066MHz] will appear only in AM2+ CPU. ► DRAM Timing Mode When both DCTs (DRAM controller) are enabled in unganged mode, BIOS must initialize the frequency of each DCT in order, you also can configure the timings manually. Settings are : [Auto], [DCT 0], [DCT 1], [Both]. [DCT 1] and [Both] will appear only in AM2+ CPU. ► Current 2T Mode This item will appear only when the "Memory Speed Mode" is set to [Limit] or [Manual]. It is used to set normal clock timing, which will provide steady system performance. The default value is [Auto]. PCIE 16X Port 1 ► Gen2 High Speed Mode 35
