common SDRAM memory you have is 168 pins with two asymmetric notches on the pin. On both sides of the SDRAM memory, you can also find that each has a notch. If it is pc100/133 SDRAM, it will include a 8-pin SPD chip on the memory strip, which is a necessary and important symbol for identifying pc100/133 memory. But we also have to note that there is a SPD chip does not necessarily represent this SDRAM memo
coefficient. There is a ratio between the CPU clock speed and the external frequency, which is the multiplier coefficient. The multiplier value ranges from 1.5 to 23, and is measured at an interval of 0.5. The frequency is multiplied by the multiplier, so any increase can increase the CPU frequency. Because the frequency does not directly represent the computing speed, under certain circumstances, it is likely that the actual computing speed of the CPU with a higher frequency is low. Therefore,
Rambus memory is a high-performance, chip-chip interface technology of the next generation of storage products, it enables the next generation of processors to play the best function. At present, the RAMBUS memory can provide 600, 800 and 1066MHz three kinds of speed, the main currently has 64m,128m,256m,512m four kinds of specifications. RAMBUS Inc. claims that the new technology offers 10 times times more common DRAM and three times times the PC100

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
Q: My CPU is Celeron 366, from 366MHz to 550MHz, boot into Windows 98 o'clock, always prompt "registry damage, restart automatic repair", restart after you can enter, but shut down and then boot, or appear the above error, this is going on, Is it related to my overclocking use of CPU?A: This problem is caused by CPU overclocking. Because CPU overclocking, FSB increased, the corresponding memory working frequency to improve, if the quality of memory does not pass, can not work under 100MHZ, will
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

) clock signals, and the third and fourth generation, due to their fast operating frequency, use a differential clock signal that can reduce interference as a synchronous clock. The clock frequency of the SDR SDRAM is the frequency of data storage, and the first generation of memory is named after the clock frequency, such as pc100,pc133, which indicates that the clock signal is 100 or 133MHz, and the data read and write rate is 100 or 133MHz.

User asked: I have a computer, configured for Celeron Ⅲ1.2ghz, 512MB SDRAM, now I add a FX5200 (128mb/128bit) of the video card. But do not know why, playing the game is always card machine, even play CS is not fluent, not as good as the original integrated graphics card, is not related to the AGP 8x? In addition, I have a apacer 256MB memory, but if the two plug in the system is very unstable, how to solve?
