Two types of SDRAM modules are the 2-clock and the 4-clock module. Structurally, they are the same, but they are accessed differently. A 2-clock SDRAM module is set up so that each clock cycle accesses two chips on the module. A 4-clock SDRAM setup accesses 4 chips per clock cycle. To choose what kind to get, you must look into the motherboard''s documentation. 4-clock modules are the more commonly used. The typical indication of the wrong type being used is a system giving error samsungmemory beeps and not booting as it samsungmemory cannot use the memory installed. The system will not proceed past POST (Power On Self Test). 2-clock was only used in 66 MHz systems. All PC 100 and PC 133 memory is 4-clock only. Do all of your SDRAM modules use SPD? SPD, or Serial samsungmemory Presence Detect, is a program in an EEPROM chip on the modules of SDRAM (Synchronous Dynamic Random Access Memory). It samsungmemory tells the system’s BIOS what the specifications and settings of the memory module are. All of our SDRAM DIMMs have SPD programming. The system BIOS should therefore be set on AutoDetection for memory. What is the difference between 2-clock and 4-clock memory? Two types of SDRAM modules are the 2-clock and the 4-clock module.
