processors that support EM64T technology: The traditional IA-32 mode (legacy, IA-32 mode) and the ia-32e extension mode (ia-32e mode). In a processor that supports EM64T technology, there is a widget called the extended function Activation register (extended feature enable Register,ia32_efer), where the Bit10 controls whether or not EM64T is active. Bit10 is known as the ia-32e mode active (ia-32e mode) or long pattern is valid (long model Active,lma). When Lma=0, the processor runs as a standa
Computer hardware and Computer Configuration knowledge Encyclopedia. This article from the CPU, graphics, memory, motherboard, hard disk and other computer hardware introduction, including a variety of brands, parameters and performance and other aspects of the comparison.

is 100÷3=33.3MHZ,AGP is Pcix2=66.6mhz, The frequency of AGP at 133MHz FSB is 133÷3x2=88.7mhz, because the frequency of the AGP is increased to 88.7MHz because of the 133MHz FSB used by ATHLONXP. Therefore, the display black screen is clearly for the video card, the video card to reduce the operating frequency, the system back to normal.

Nforce2 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 Pentium 4 has a much higher demand for memory bandwidth than AMD Athlon XP. The Intel Pentium 4 processor and North Bridge chip data transfer using QDR (Quad data Rate, four data transmission) technology, the FSB is 4 time

The service can dynamically adjust the frequency of the CPU at runtime to conserve energy (power saving). Many laptops have CPU support for this feature, and more and more desktops are now supporting this feature. If your CPU is: Petium-m,centrino,amd powernow, Transmetta,intel speedstep,athlon-64,

These days when you do MDT, you will always encounter x86\x64\ia64 these several folders. The first two are common, and are often encountered since the Win7 system appears. So I guess IA64 should also be some kind of architecture or version of the CPU. Now to the three made a summary.
x86 or 80x86 is the general term of a microprocessor architecture that Intel first developed and manufactured. The older processor names in this series are represented numerically and end with "86", including Intel
