in performance degradation. Therefore, the heat dissipation must be done well during overclocking.2. unreasonable overclocking parameters affect performanceAn unreasonable overclocking parameter may also cause performance degradation. For example, the default frequency of an N-card is 576/1242/2000 MHz (core/shader/memo-ry ), if the Shader frequency is over 1800 MHz, the core frequency is about 812/1800 MHz, and the video card performance is the highest. If the core frequency is increased to 85

It almost determines all functions of the motherboard and is the most important chip in the motherboard. There are a lot of old materials on the Internet, such as the "chipset" entry under Baidu encyclopedia.

alignment. So pay attention to byte sequence conversion. When the powercp processor reads int_ack, the host converts the read operation into a PCI bus to interrupt the response transaction. It is the configuration space of 64 bytes that the PCI device must support. The value range is 0x00-0x3f: Many PCI devices only support 64-byte configuration space. The differences between PCI and PCIe configuration spaces are as follows: PCI/PCI-X and

Multi-port server Nic solution in Bypass Mode

PCI Express, with four-port gigabit connections providing higher network bandwidth Using a four-port Gigabit server Nic on any server, especially on Intrusion Prevention servers, can demonstrate significant advantages. The four-port PCI Express (PCIe) server Nic can provide four network connections from a single server slot, so that other server slots can be retained for more applications. Multiple Gigabit ports can increase network bandwidth through

What is overclocking how to achieve CPU overclocking

The overclocking of the computer is to improve the working frequency of the CPU, graphics and other hardware by artificial way, so that they work stably under the rated frequency state. The Intel P4C 2.4GHz CPU For example, its rated operating frequency is 2.4GHz, if the operating frequency to 2.6GHz, the system can still run stably, then the overclocking was successful. The main purpose of CPU overclocking is to improve the CPU's operating frequency, that is, the CPU's central frequency. The C
