目前,内存已成为决定计算机整体性能的重要因素之一。选购内存时,常常要面对PC100和PC133内存。究竟什么是PC100与PC133内存,它们之间又有什么区别呢?PC100与PC133内存是指分别符合PC100、PC133标准的内存。PC100标准PC100标准中有两项重要的SDRAV技术指标,即TCK与TAC。TCK(Clock Cycle Time)为内存时钟周期,由外频决定。TAC(Access Time From CLK) Currently, memory has become an important factor in determining the overall performance of a computer. When purchasing memory, often have to face PC100 and PC133 memory. What exactly is PC100 and PC133 memory, what is the difference between them? PC100 and PC133 memory are respectively in line with PC100, PC133 standard memory. There are two important SDRAV specifications in the PC100 standard PC100 standard, TCK and TAC. TCK (Clock Cycle Time) is the memory clock cycle, determined by the FSB. TAC (Access Time From CLK)
