tailieunhanh - A complete illustrated Guide to the PC Hardware phần 7

Không có câu hỏi mà chương trình là tuyệt vời để viết các trang chủ. Tuy nhiên, chức năng của nó là khá nguyên thủy. Là hầu như không có bất kỳ phím tắt bàn phím, và không có macro. Nhiều chương trình của Windows được thiết kế như thế này, và nó thực sự có thể được khá cố gắng | An illustrated Guide to Over-clocking. 153 MHz One quarter MHz Side effects When we increase the PCI bus speed a number of units are affected. They may not always agree with the faster pace. This includes The EIDE hard disk The video card The network controller and other I O cards. My own experiment with Pentium II In 1997 I experimented with a very early Pentium II which was bought as a 233 MHz model. First I made it run at 31 2 X 75 MHz. It worked fine with CPU RAM 10 ns SD and hard disk IBM DHEA . But the net card a cheap 10 100 Ethernet card refused. When I copied large volumes of files on the net it froze up - stopped. It was quite obvious that the problem was in the net card. I had to accept the traditional 66 MHz. But to soothe the pain it turned out to run excellently with a clock factor of 4 - thus at 266 MHz. Within a couple of weeks I was in the mood to experiment again. I now found an adjustment in the setup program. It is called PCI latency. It is not explained anywhere but it has a default value of 32. I increased it to 36 and increased the bus frequency to 75 MHz - it works. Now the net card runs without problems. Then I hoped to speed the system bus up to 83 MHz which should give a significant performance improvement for all RAM transport. My 10 ns SD RAM can certainly handle 83 MHz. But no it did not work. Regardless of the PCI latency the PC would not start. This indicates that the PCI latency setting does not work like I expected. Maybe it has nothing to with this - I do not know. My explanation is that the video card could not tolerate the MHz PCI frequency. Nothing appeared on the screen. Now the PC runs fine at 4 X 75 300 MHz. There can be an occasional unexplained break-down in Windows 95 that happens under other circumstances also which I blame on the drastic over clocking. However the advantages of the significant performance improvement far exceed the annoyance of these small interruptions which happen far from daily. Problems .
