Hello, I just bought a new motherboard and CPU and tried install Window XP. Anyway, it seems to have a serious problem. Here is the spec of my system ECS K7S5A Pro Athlon XP2000+ ATI Redeon 7500 DDR 64MB RAM PC133 256 MB Harddisk Western Digital 30GB Power Supply 300W Here is the story. After I put everything together, I install window XP then it everything works great. System runs smoothly and I can install motherboard drivers and other software without any problem. However, I figure out that the system detects CPU as Athlon 1.2GHz. So I come back to BIOS set up and change CPU/RAM speed from 100/100 to 133/133. Now when the computer starts up, it can recognize CPU as Athlon XP2000+. Anyway, when the Window XP starts up, the computer keeps rebooting itself. Some times, window XP can start up successfully, but when I try to install motherboard driver, it always fails. Never success to install motherboard driver when run at 133/133. Here is the conclusion, it works fine if I run it at CPU/RAM speed 100/100. But if I run it at 133/133, everything mess up and never works. Please let me know your comment and advice. Thanks. PS: I check CPU temperature already. No problem with overheat.

I built a comp with one of these motherboards and found it was fussy about the memory sticks used in it.With some sticks I got hangs ,reboots and graphics corruption. With one stick of Corsair DDR it didn't even post.So I ended up getting memory verified for that board from the Crucial website using their system selector Kingston offer a similar service. Joe

the k7s5a is noted for not working well with sdram, and running at 100fsb often fixes it. Eddie's link has details.

looks like there's a typo in eddie's link. http://pub65.ezboard.com/bk7s5amotherboardforum http://www.ocworkbench.com/ocwbcgi/ultimatebb.cgi?ubb=forum;f=35;DaysPrune=60
