operating speed is synchronized with the system bus speed. SDRAM memory is divided into PC66, PC100, PC133 and other different specifications, and the number behind the specification represents the maximum function of the memory of the system bus speed, such as PC100, which means that the memory can be in the system bus 100MHz computer synchronization work. Synchronization with the system bus speed, which is synchronized with the system clock, avoids

reach 1GB, this is because s3c2440 will be 1GB of addressing space into 8 banks (BANK0~BANK7), Each bank corresponds to a chip selection signal line NGCS0~NGCS7, when accessing bankx, NGCSX pin level pull low, used to select the foreign connection device, s3c2440 through 8 signal lines and 27 address lines, you can access 1GB. As shown in 2-48.Figure 2-48 s3c244

Ethernet or 10/100 Fast Ethernet interfaces, and a vac. PIX535 Unlimited software version The PIX 535, which contains unlimited software licenses, is equipped with 1GB of RAM, supports up to 8 Gigabit Ethernet or 10/100 Fast Ethernet interfaces, and a vac. In addition, the PIX 535-ur also adds the ability to share state information with the hot standby pix to achieve full firewall redundancy. 　　 Performance Summary of PIX535 P

The larger the memory, the faster the machine? I think most of the answers are yes, the hints from 256M to 512M are obvious, so take it for granted that the promotion from 512M to 1G will be obvious. But I use my experience to tell you that 1G of memory is slower than 512M, of course, if you do not set anything. A few days ago I extended my Compaq n410c to 1G of memory, 2x512m pc133 SD, the results of the expansion found that the machine is not only

, Windows often automatically enter Safe mode This type of failure is generally due to the motherboard and memory stripe incompatible or bad quality, common in PC133 memory for some do not support the PC133 memory of the motherboard, you can try to reduce the memory reading speed in the CMOS settings to see if the problem can be solved, if not, then only replace the memory bar. V. Random crash Such failu

down the frequency of the registry error significantly reduced, more suspicious of the fault caused by the CPU, deliberately replaced the CPU, but the fault has not disappeared, still appear. To completely troubleshoot the problem, use the substitution method to test, finally found that the culprit is the 64MB of memory. Fault Analysis: The machine is in the overclocking state for a long time, CPU and memory clock frequency are 133MHz. That 64MB of memory is hy-7k chip, work is also poor, the

registry error frequency is significantly reduced. After the CPU is changed, the fault does not disappear, it still appears from time to time. In order to completely eliminate the fault, the replacement method is used for testing, and the culprit is the 64 MB memory. The computer has been running at a high frequency for a long time. The clock frequencies of CPU and memory are both 133 MHz. The 64 MB memory is used by the HY-7K chip, the work is also poor, long-term 13 3 MHz external frequency r

, referred to as SR). Regardless of the Refresh method, you do not need to provide the row address information externally, because this is an internal automatic operation.For AR, there is a line address generator (also called a refresh counter) inside the SDRAM that is used to automatically generate the line address sequentially. Because the refresh is for all the storage in a row, no column addressing is required, or CAS is valid before RAS. Therefore, AR is also known as CBR (CAS before RAS, c

This may be the case for several reasons: 1. This may be due to incorrect BIOS settings. 2. It may also be a question of the sequence of memory detections. The following are the problem-solving methods: 1. Into the BIOS, the PC133 memory parameters set to the same speed as the PC100 memory, that is SDRAM. 2. Unplug the original PC100 memory after the boot, the smooth detection of PC133 memory, into the
