Marciff Posted June 21, 2005 Share Posted June 21, 2005 I upgraded my cpu from a P4 2.26GHz Northwood (533MHz bus) to a P4 2.8GHz Northwood (533 MHz bus) but it is showing up as 1.8GHz. My motherboard is a Asus P4B533-V with the 1009.002 beta bios. I had the 1008 but flashed it to 1009 to see if the CPU would work at 2.8GHz. What is wrong? I attached a screenshot of CPU-Z Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/ Share on other sites More sharing options...
gdodson Posted June 21, 2005 Share Posted June 21, 2005 Look at the speed in your BIOS, CPUZ could be wrong. Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099462 Share on other sites More sharing options...
Marciff Posted June 21, 2005 Author Share Posted June 21, 2005 If I choose the auto detect, it sets it to 1.4GHz. When the computer starts up it shows what CPUZ reports and not the correct speed.

amrinders87 Posted June 21, 2005 Share Posted June 21, 2005 and how do you know the cpu is P4 2.8GHz? Do you have the box? I would contact Intel to find out if it is a 2.8 Ghz Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099478 Share on other sites More sharing options...
Andrew179 Posted June 21, 2005 Share Posted June 21, 2005 In BIOS settings, the front speed bus (FSB) should be set to 200MHz instead of 133MHz. 200MHz * 14 multiplier = 2800MHz Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099474 Share on other sites More sharing options...
Marciff Posted June 21, 2005 Author Share Posted June 21, 2005 Andrew, isn't that for processors with a 800MHz bus though? Mine is 533Mhz Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099480 Share on other sites More sharing options...

In that case, the multiplier should be changed to 21.

NextGen_Gamer Posted June 21, 2005 Share Posted June 21, 2005 Is your CPU overheating and thermal throttling is kicking in? I'm not sure if this even applies to the older 533MHz FSB "Northwood" cores, so someone correct me on this if I'm wrong. You could check your CPU's temperature in the BIOS, though. If it is anything over 60? C (and especially if it is around 70? C), then overheating could be your problem.

In the manual, it says frequency multiplier is only available on unlocked CPUs Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099555 Share on other sites More sharing options...
Marciff Posted June 21, 2005 Author Share Posted June 21, 2005 The CPU that I received has a 800MHz bus. I found this out using Intel's CPU identifier. So that is the problem! Thanks guys Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586099693 Share on other sites More sharing options...

Is it your fault or the vendors? :ninja: Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586100466 Share on other sites More sharing options...
scaryperson27 Posted June 22, 2005 Share Posted June 22, 2005 im guessing that it isnt the bios that set it to 133x4=533fsb, because the bios would boot it to 100x4=400fsb. So basically Im guessing that the company had either gotten the chip wrong or that you put in the wrong fsb frequency. I hope you have ram that can handle 200x4=800fsb : :whistle: Link to comment https://www.neowin.net/forum/topic/335085-cpu-not-showing-correct-speed/#findComment-586101132 Share on other sites More sharing options...
