    System properties.

    If I right click MyComputer then Properties I can see that my CPU is "Pentium(R) 4 CPU 2.53GHz" - no suprise there. The next line says simply "1.89 GHz", no caption, no explanation no nothing, just that. Someone care to enlighten me as to what that second line means.

    I also noticed during a recent reboot, that the b/w intro screen says something like Pentium 4 1.9GHz. The machine is not hot so I don't think it is throttling. <fx> shrugs shoulders </fx>

    what OS are you using? did you make any OC to your computer?

    XP.

    >>> did you make any OC to your computer?

    OC?

    Whatever that is, I doubt I did it! The only changes I have made to the machine since I had it built was to swap out the CD-ROM drive for a DVD-ROM drive.

    *** EDIT ***

    If OC = overclock then - no.

    I'm not sure how throttling works... but is it possible that it does not run at full speed until you need it? And that's what you're seeing?

    ober:

    I believe it is the other way round. It runs at normal speed until it has to slow down because it is too warm. If you watch toms processor cooking film, you can see the processor slowing down in steps before stopping.

    I am running seti@home so have 100% cpu usage at all times.

    The second line, on my PC anyway means the CPU speed. Simple as that.

    I use XP

    On mine it is because I use AMD presumably.

    IE AMD chips run slower than their 'name' .

    So if you had a 1700XP the next line down shows 1.47 GHZ-the actual speed.

    The next line shows your RAM.

    Sorted-except you run a Pentium......ooops !
    Such is life.

    Well, what programs like Sandra tell about your processor, I mean, the real speed? I'm just curious now.

    I found that Sandra thing, quite a tool. It does, indeed appear that my 2.53GHz is running at 1.89GHz.

    Something else it tells me is that my mainboard temperature is too high, (77C), although the processor temperature is relatively low, (30C).

    From another site, I have learnt that my system is operating with a 400MHz fsb, rather than 533MHz.

    What I don't know at the moment is if the high temperature on the mb is causing some throttling, or what. I don't want to adjust the CPU settings, (make them higher), if that will result in more heating, (seems likely that it would).

    Well, if Sandra is telling this, your CPU is really 1.89 (at least until now) maybe you aren't using all the power of your system, try going in the BIOS and check the settings, and if you're sure your CPU is 2.53, try making an OC there, your CPU should support, but remember only if you're sure! else, I don't think it will support he will be toasted.

    I don't know at the moment is if the high temperature on the mb is causing some throttling
    Probally but not sure, and hell this temperature it's really high, just be carefull.

    if that will result in more heating
    It will... and I don't recommend you.

    Have you any idea where/how the mainboard temperature is measured? I would have thought that if the CPU is running at 30C it could not be heating the mb to 77C, but something else could be.

    To help the guys on the other board I had a look inside the box, both the Northbridge and Southbridge chips are buried under some impressive looking heatsinks, but they do not have fans fitted.

    Something else I noticed is that there are some pins on the mb for fitting a second system fan, I was wondering if a case fan may be in order. From the sites I've browsed, I can't see that it should be necessary, but then, they have never mentioned a 77C mb!

    This is my mb. I am sure now it is this model, (that's why I had the box open). The SiS645DX is a 533MHz fsb chip, but I would seem to be running at 400MHz.

    I would say that A) you don't have the right hardware because I don't think memory is going to slow down... I could be wrong...

    and B) I would definately say that at 77C some throttling is occuring.

    I don't understand your A! The memory?

    With your B), as I understand it, the throttling is inbuilt into the CPU, but if the CPU is running at 30C, Sandra tells me it is fine, (and hence I guess it would not throttle), but then it goes on to say the mb Temp is too high... I can't see how a 30C chip can heat a board to 77C?

    I have learnt a lot today, but as always, all that does is shows the depth of my ignorance! Without that Sandra thing, I would not be worried, because everything else, (BIOS and system tools), is telling me the temperatures are okay.

    I have been convinced I should up my fsb, so am going to try. I'll let you know what happens, of course, if I fry this machine, I will be back to the slow dialup, so it may not be for a while...

    *** EDIT ***

    Okay, it all still seems to be working. Interestingly, Itried that performance test that was all the rage a few weeks back. With my CPU/DRAM as it was, (400MHz fsb), I get a score of 173/404.7 MFlops, bumping the fsb to 533MHz I get 217/534.4 MFlops, and pushing the SDRAM up to 333MHz, (I have PC2700 DDR), I get 221/545.8 MFlops.

    The BIOS temperatures seem fine. Sandra is still concerned, BUT, even with the higher frequencies, the figure she is giving me for the mb Temp is the same, i.e. 77C. wWhat has changed is that she says the PSU Temp has risen from 38C to 47C - now I'm suspecting that Sandra has her thermometer in the wrong place!

    I'm going to try running like this for a while - it should be fine, that is what the board/CPU/RAM are supposed to be set too.

    Interesting temperature's you got there but i am sure that the 38-47 for the CPU is actually the CPU as a increase in speed wouold naturally result in a increase in Temp. Further more i seriously doubt a MB could live under a temperature of 77C and i seriously doubt that if it was runnin at 77C your room would be anywhere under 30-40C unless you open some windows.... I'd say that either SiSandra is reading the MB tempo wrong or the sensor is messed up

    I just can't imagine that 77° C reading is right... I mean seriously that's about 170° F! You could cook an egg in your computer

    At current I'm running 42/26 for CPU/mobo. I have my maximum heat threshold for the mobo set to 60°, any hotter and the alarms will start ringing.

    If that temp is right (check temps in BIOS as well) you may have some serious problems
