Note upper temp spec limit of 1.0GHz Athlon is 90 deg C, so 40 to 50 deg C is normal running temperature. Mine runs at 42 to 49 deg C. Just looking here..experts-exchange.com (you need to sign up and log in) here is a little extract of one question. I don't have a paid account, if I did I could maybe search on your particular 1.0 GHz Athlon model. experts-exchange.com =======================================================Question: Hi, I've just put together a pc for the first time and have managed to wade my way through everything so far. Everything seems ok, is stable but perhaps not as quick as I was expecting. So I checked out system information and its showing my chip as only being 1.3Ghz when it should be 2.167Ghz. I installed Norton and it says the same thing so I did a search and found a message on this forum about aidi32. So I've installed and run that and this is showing my chip info as this - CPU Properties: CPU Type AMD Athlon XP-A, 1300 MHz (6.5 x 200) 1700+ CPU Alias Barton L1 Code Cache 64 KB L1 Data Cache 64 KB L2 Cache 512 KB (On-Die, Full-Speed) =========================================================Answers: You're currently running your cpu at 100MHz and needs it to run at 166MHz. this is set in your bios. that setting you show "AMD Athlon XP-A, 1300 MHz (6.5 x 200) 1700+" is what tells us everything. It should show 333MHz, not 200MHz. Once you change that setting to 166 you'll be at full speed. *Note: 13 x 100 = 1300MHz, 13 x 166.66 = 2167MHz. Hope that helps! ======================================================== FYI, this is set from the 'Advanced Chipset Features' in your bios. the entry in "CPU External Freq (MHz)" on that page needs to be changed from 100 to 166. ========================================================== Just read your 'unknown territory' post: Do you know how to enter the bios? Just press [DEL] as you startup your machine. (You'll see the 'Press [Del] to enter setup...' prompt, or something to that effect as you start your machine) Once in your bios, press the right-arrow button to get from 'Main' to 'Advanced' menu. Under advanced you'll see the headings 'Advanced Bios Features', then 'Advanced Chipset Features' (as well as others). Choose the 'Advanced Chipset Features' menu item by pressing the down-arrow key. then change the first setting, 'CPU External Freq (MHz)' on that page. Then press [F10] to save and exit your bios. ==================================================== Perfect, running like a dream now. Thanks!
