Unlike SDRAM memory that supports one operation per the computer's clock Audio: AC'97 compliant Audio CODEC (Line-in, Line-out, Mic-in by pin header) cycle, DDR SDRAM memory can do two WDT: software programmable support 1~255 second system reset operations per clock cycle, thereby doubling the ™ memory bandwidth over the corresponding sinle-ISAPlus : Design to enhance the ISA bus drive capability (64mA) data-rate SDRAM. Hardware Monitoring (CPU Vcore; Vcc; CPU/System Fan speed and Thermal) Technically, the DDR memory bus runs at memory- bus clock rate of 100MHz for PC1600, 133MHz for ATX power control function: meet ACPI 1.1 PC2100, and 166MHz for PC2700. However, each Power consumption: +5V@5A, +12V@6.6A, 12V power request min. 8A. DDR memory module and memory chip run at an effective (data) rate of 200MHz, 266MHz, and (P4 2.2GHz CPU with 2GB DDR SDRAM, Windows 2000) 333MHz. The computer industry has adopted a Operating Temp: 0-60°C (CPU cooler needed) practical convention of just referring to the data rate as the DDR DIMM speed. So, PC1600 DIMMs Relative Humidity: 5-95%, non-condensing are said to run at 200Mhz, PC2100 at 266MHz etc. GW: 900g DDR vs SDRAM Modules DDR DIMMs and SO-DIMMs have the same physical dimensions as their SDRAM counterparts, but have a different footprints. DDR DIMMs have ORDERING INFORMATION 184 pins compared to 168-pins for SDRAM DIMMs. DDR SO-DIMMs have 200 pins compared ROCKY-4784EVG PICMG Socket 478 Base SBC with VGA(32MB), Audio, LAN to 144 pins for SDRAM SO-DIMMs. DDR DIMMs and SO-DIMMs also have a different and Gigabit LAN notch (called 'key') that will only fit motherboards ROCKY-4784EV PICMG Socket 478 Base SBC with VGA(32MB), Audio, LAN and systems especially designed for DDR. CB-USB02 Dual ports USB cable with bracket DDR modules will not fit into PC100 or PC133 sockers and are not backward compatible.ACE-840A/AP 400W ATX power supply for P4 system ACE-940AP 400W AT power supply for P4 system 2-1
