frequency, that is, the CPU speed of the front-end bus is 533 MHz (133mhz external frequency × 4 times speed), up to 4.2 Gb/s (533mhz × 8. Therefore, we can calculate the CPU bandwidth of other front-end Bus: the transmission bandwidth of 266 MHz FSB is 2.1 Gb/s, and that of 333 MHz FSB is 2.7 Gb/s; the transmission bandwidth of 400 MHz FSB is 3.2 Gb/s, the transmission bandwidth of 533 MHz FSB is 4.2 Gb/s, and the transmission bandwidth of 800 MHz FSB is 6.4 Gb/s.

Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs. For details, FSB is P

Professional Edition requires at least MB of memory. In actual use, MB can ensure the normal operation of the system. Therefore, with the development of PC, the memory capacity will continue to expand, and the speed will continue to increase.Now let's talk about the memory speed problem. The memory speed is determined

Axx aspect is the NVIDIANforce2 series. The Dual-channel memory technology is a low-cost, High-performance solution that solves the problem of CPU bus bandwidth and memory bandwidth. Now that the CPU's FSB (front bus frequency) is getting higher, Intel PENTIUM4 has a much higher demand for memory bandwidth than AXXATHLONXP. The Intel PENTIUM4 processor and No

). In other words, DDR2 memory each clock can read/write data at 4 times times the speed of the external bus, and can run at 4 times times the speed of the internal control bus. In addition, because the DDR2 standard stipulates that all DDR2 memory is in FBGA package form, and different from the current widely used TSOP/TSOP-II package form, the FBGA package can provide better electrical performance and hea

Memory overflow and Memory leakage, memory overflow and Memory leakage Basic Concepts Memory overflow out of memory means that the program does not have enough memory space for use when

When we use C + + as the underlying driver, we often encounter a warning of insufficient memory, the reason is often because of memory overflow, leakage or cross-border and other reasons. So what's the connection between them? memory overflow (out of memory) Refers to a program that does not have enough

when we use C + + to do the underlying driver, often encounter memory shortage warning, the reason is often because of memory overflow, leakage or cross-border reasons. So what's the connection between them? memory overflow (out of Memories)means that the program does not have enough memory space for it to use when it

Friends who often pay attention to three piece market changes will find that the current large capacity of memory is getting cheaper, which makes many users have the idea of upgrading memory. Looking at the current memory market, new to dig up the brand is really a lot, in the frequency of memory, now DDR266, DDR33

Http://bbs.gameres.com/showthread.asp? Threadid = 57428 The excerpt is as follows: Three types of memory, such as the local memory and system memory of the video card, all of us know that the local memory of the video card is the memory of the video card, and the system

Android obtains the total memory and available memory of the mobile phone. In Android development, sometimes we want to obtain some hardware information about the mobile phone, such as the total memory and available memory size of the Android phone. How can this be implemented?By reading the "/proc/meminfo" file, you c

Memory-Working set: the sum of the amount of memory in a private working set and the amount of memory that the process is using and can be shared by other processes. Memory-Peak Working set: The maximum number of working set memory used by the process.

How to set the optimal 4G memory virtual memory ?, 4G memory virtual memory Memory is one of the important components in the computer and serves as a bridge to communicate with the CPU. So, do you know how much virtual memory sho

From the compiler perspective, memory is divided into three situations: 1. The memory area that has been determined during system initialization and will not change. It generally refers to global variables and static variable arrays. 2. memory on the stack: generally refers to the local variables in the function. The memory
