Lowering the FSB

Hi,
I was just playing with DOT. I tried to get the clockspeed in idle state as low as possible. I knew that in BIOS you couldn't get lower that 190FSB, so I chose 190 and a DOT of 7%.
To my surprise I was able lowering the clockspeed to 166 with CoreCenter. So now the CPU runs in idle state at 1667Mhz and 2150Mhz at full load. Any lower settings possible? I have a 3200+ Clawhammer.

As far as I know I've all the required drivers installed, Cool&Quiet and the minimal powerscheme enabled. But still it idles not lower then 1666Mhz.
Is your system in standby mode when it runs at 800mhz? Cause that is the only reason I can think of as my system wouldn't turn of its harddisks for example. Power management is enabled in BIOS btw.
Not really a problem here -I even doubt I'll keep DOT enabled- but when I hear 'rumors' that systems idle at 800Mhz I want at least tried that once on my system too.

  • I've been giving HD videos in MTS format and convert the for editing in FCE.  Looks good in the program, but when I export the finished film, quality had been noticeable diminished.  Is there any way to prevent FCE from lowering the output quality?

    Hello -
    I've been sent HD footage in MTS format and converted it to Mp4 for editing in FCE.  It looks good in FCE but when I export the movie, the quality is noticably diminished.   Is there any way I can prevent FCE from lowering the quality on export?
    Thanks.

    >I use Foxreal video converter for Mac to convert the MTS using the Apple intermediate codec setting and the problem is that I don't get image, just audio
    My thought would be to NOT use Foxreal video converter.
    Use MPEG Streamclip or Clipwrap.

  • Importing custom slideshows that are created in iPhoto without lowering the quality to play on AppleTV

    Hi,
    My wife is a wedding photographer, so for part of her presentation process I create custom slideshows in iPhoto with music and the pictures presented in a certain order and at a certain pace. The slideshows look awesome on the computer. To get them to play on my 1st generation AppleTV, they want me to export the custom slideshow to iTunes at a much lower resolution to where it will play on the AppleTV. There has to be a better way to do this. Right now, by the time they're playable on the AppleTV, the picture quality is noticeably worse than the original presentation.
    I called apple and they first suggested selecting the slideshows in the events tab under photos on the AppleTV in iTunes. The pictures look great, but the custom slide show element is gone as it plays them in the order and pace it wants to play them with all background music stripped away. The gentleman transferred me to a 'Senior Advisor', who said the are not allow to assist on content matters. I told him it's not a matter of the content, but the process of creating it in iPhoto (Apple program), lowering the quality and exporting it to iTunes (Apple program), to watch it through AppleTV (Apple product). I got the feeling that was his way of saying he didn't really want to deal with this.
    He directed me to this board to see if someone else has experienced this as well or has a solution.
    I'm using AppleTV - 1st generation, and iLife '09.
    Any suggestions would be GREATLY appreciated.
    Dave

    Use the export option from the bottom of the slideshow
    and choose the custom export settings.

  • Overclocking the fsb on a kt4ultra

    I was wondering what (with standard cooling) people are getting overclocking the fsb on kt4 ultra.
    I am rock stable at 142mhz with a xp1800 with a coolermaster heatsink - the cpu is running at about 35-36 degrees. If I increase this the machine will reboot itself soon after getting into windows.
    I suspect the problem is not with the cpu but with the pci been overclocked as I have two 80gig ibm drives RAID'ed on the serial ATA and I don't think the controller can handle it.
    I suppose I could try booting at 151mhz to drop the multipler on the pci but are these cpu's able to operate at these sorts of speeds? Anybody got any thoughts?
    By the way the RAM is pc2700 from crucial so no problem there

    Try with your FSB higher to drop the PCI multi.  Watch your temps closely with Speed Fan, or PC Alert if it actually boots and seems stable.  If it gets around 50-60C it is too hot, but is ok so you can shut it down.  Then shut down your computer and get a better heatsink/fan.  If you do get too much clock speed, you can lower the clock multi, so you can have your FSB still higher, but your processor speed lower.

  • When I export an iMovie Project with a sped up clip, the sound is squeaky even though I lowered the pitch in iMovie. Help?

    I've lowered the pitch of th video in iMovie, but when exported, the sound is very high pitched and squeaky.

    While we all have MacBooks in this forum not all of us use iMovie. There's an iMovie Support Community where everybody uses iMovie. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/ilife/imovie

  • Can you operate the mac book pro 15 inch with out the battery?  I read somewhere in a post that it lowers the power to about 1 gig.  I asked apple and they said it is not true because you can use it with or without both together without affecting op pw

    can you operate the mac book pro 15 inch with out the battery?  I read somewhere in a post that it lowers the power to about 1 gig with out the battery.  I asked apple and they said it is not true because you can use the comp with the power adapter and battery together or either by itself and it will not effect the 2.16 gig.  Thank you.

    If you remove the battery the CPU power will be cut by 50% (whatever they told you) so that there's no lack of power or overheating issues. It's best to always keep the battery in.

  • Lowering the CPU voltage?

    What kind os problems can I have if I lower the CPU voltage to, for example, 1.4V???
    Will it cause stability problems?
    Can I damage anything?
    Please help.

    You can only lower it so far before it will begin to act quirky and that can cause all sorts of problems.  I am not sure if you will actually damage your hardware, but you may pooch your OS and be forced to reinstall everything.  It is generally better to lower your multiplier if you are trying to lower power consumption.  What exactly are you trying to accomplish?
    RB
    Ok I see...
    I'm just trying to lower my CPU temps, but actually I do not know if temp is my problem. I got 2 BSOD while running prime95 with everything at stock. But I remember that when it crashed my CPU temp was around 52C. Isn't that too hot? I do not know...
    And one of the times, after the BSOD, I tried to reset the machine and it did not post, giving me beeps and leds saying "memory problem"...
    ( I was having this exact beeps and leds problem EVERYTIME I tried to turn on the machine, but I had a low amps PSU. After I changed to this one in my sig, everything started to work fine, until this...  )
    Any ideas please?

  • Increasing the FSB question...n00b!

    OK, I'm using an KTV4L with a +1700 CPU. If I drop the multiplier, and increase the FSB to 166, will it be stable? If so, how much more heat will it generate? Or is this just a bad idea all together?
    lol
    thanx

    not a great deal more,depends on overall speed it ends up at
    provided your ram can take it it will be faster

  • Setting the FSB

    I got my cpu running at optimum but the problem is i want to raise the FSB from 134 to 166. The problem is its running at 134x15, but in the bios i have the channel selected at x7.0 is there anyway i can change this so i can run 166x12?? Please anyone help.

    What CPU and motherboard are you running,  It sounds as your CPU is still locked and therefor you cant change multipliers

    Im having the exact same problems...bios wont post past 150fsb..i have the xp1600+ as well locked.
    BUT.......after i get into windows, i can set the FSB up to 160....figure that one out :]

    This is very frustrating, why is it others can but i for some reason cant and yet i can get it to 150x10.5 Although its a bit unstable
    Also can someone please let me know the optimal seeings for the bios and doi need to enable IDE bus master as its disabled.

  • OC: can change multiplier but NOT the FSB on K7N2 Delta ILSR XP1800+ TB 'A'

    I have had a good look at the various threads in the forum which to be honest confused me a bit more.  I explain.
    The good news (for me): so far I have successfully changed the clock speed of a Thoroughbred 'A' XP1800+ on a K7N2 Delta board.  Default is 11.5 but 12.5 or 8 are working fine.  On 12.5 the mobo recognises the cpu as a XP2000+.
    The bad news: I cannot change the FSB from 133 to anything else even in Advanced Chipset Features, manual, high performance settings.  Not even a lower one works for this setup.  As said above, the multiplier however IS reasonably overclockable - the system simply won't let me change the default FSB of 133.  
    As far as I understand it, the 1800+ is unlocked even in its TB 'A' version.  So the 'wire trick' won't help me I guess.
    The fairly low spec AGP card?  If so then a lower FSB should be possible.
    The memory should be fine, it's CL2.5 Crucial PC2700 333 DDR.
    BTW: I don't think the PSU is the problem here.  I had a 380W PSU in there (noisy although named silent!) which didn't change a thing.
    Any help or thoughts greatly appreciated!  
    Cheers
    Chris

    I unplugged psu, cleared cmos, applied default bios values.  Then as suggested set multiplier to auto (H/W), reboot, and set the cpu/fsb interface back to Manual.
    And it worked!  Crazy.  The system must have been stuck in some kind of loop...  anyway, thanks very much Wonkanoby for your help!
    After sorting this prob, I gradually raised the FSB to 166 while decreasing the multiplier to 9.5 = 1577MHz.  Temps didn't chage a bit which makes sense for the cpu but I expected the northbridge chip to get a bit warmer.  Don't know about memory.
    Does any of you have experience with OC a Thoroughbred 'A'?  I assume it is less OC'able than a type 'B'.
    Or in other words: where's the limit?
    Cheers

  • AMD 3000+ cannot set the fsb in order to boot

    Hi,
    My system below worked fine with an AMD 2100 chip. I recently bought a 3000+ chip and slotted in to my PC - all booted up fine.  I then changed the FSB within bios to 166 - and then rebooted - the machine didn't boot and I had to clear the CMOS.
    I worked out that I cannot set the fsb to anything above 139 fsb else the machine won't boot and I have to reclear the CMOS...I have no idea what to do
    Anyone got any ideas pleaaaaseee?????
    btw I took the cpu down to the dealer and it worked fine there.

    but before I give you my system spec - I stuck in a 550W power supply and all is fine.
    However when I clock it up to 166 system crashes - better ram needed I guess.

  • In firefox my flash player is lowering the volume for some reason.Every time when im browing youtube or other pages my volume is lowered to 10%.

    OK so when im using firefox and browsing internet,watching youtube etc. My Adobe flash player sound is

  • Lowering the export time without getting a pixellated fade in Compressor

    Hi. I'm exporting a 20 minute-long video made in Final Cut Pro, 1080i shot at 25 frames, in Compressor. The finished file needs to be 640x360 res, with a Video Bit Rate of 672 and an Audio of 128.
    My settings in Compressor are MPEG-4 for the file type, specifically an H.264 Baseline Profile one, I've got Multi-pass selected and the audio is in Stereo. Under Frame Controls, my resize filter is set to Better, with output fields to Progressive and Deinterlace set to Better. I've ticked Adaptive Details and the Rate Conversion is set to Better.
    My original settings were a lot more standard than this, with Fast selected where Better is now selected for example, and the video ended up looking presentable, but with pixellation for every cross dissolve, fade or even movement of the camera. I have looked through a few help topics on this forum and others, and the solutions I came across were to change the settings to the ones I have listed above, what I currently use.
    The problem now is that the video never gets exported! I click Submit, and the loading bar appears, moves a little, and the finishing time just goes up and up and up. Last time I tried to export the finishing time said 15 hours!
    How do I fix this without ending up with a low quality video?
    Thanks in advance.

    To begin, what is the purpose of this job? How are you going to use it?
    Open the preview window and mark a short range of representative footage with in and out points. Make your adjustments in the Inspector>Encoder  until the output file is acceptable image quality.
    That is a very low data rate for a frame size that big. Why does it have to be 672 (and BTW, there is no way to get it to come out exactly at that rate)?
    What is the source material? Are you changing the frame rate? If not don't use Frame Controls for Retiming.
    The higher you crank up Frame Controls settings the longer the encode process. Was your source file interlaced? If not, leave that alone.
    Try Main Profile and see whether the results are better.

  • Help lowering the voltage

    Hello all. I've came to this forum before, asking help to overclock my i5 3570K on my P67-GD65 motherboard. As I was running in to trouble with a game I rolled back my OC. Had it happily at stock for a while.
    A few days I've turbo overclocked it to 4.1, not to shabby. The problem is, when at full load voltages are at 1.360. In my point of view, it to damn high!
    I know that if I set the Vcore any other than AUTO I'll lose all power savings, and I don't want that... Could this value being so high because I have Vdroop set to High? On my BIOS I can only set it to High or Auto so I guess I don't have much to do 
    Can someone help me to reduce voltages so I can reduce temps also? While gaming (Skyrim, World of Tanks) tops out at 60º although I think it's a bit high with such conservative OC.

    Attached is E7681IMS.441 (Beta) you may try this bios if you wish, but there are no release notes pertaining to your issue. That does not however mean it will or won't help. If you want to test with this bios, >>Use the MSI HQ Forum USB flasher<<
    Select option 1 and point the tool at the entire compressed archive (do not extract the attachment)
    Point the tool at your fat32 formatted usb stick and then boot to that usb when the tool has completed its work.
    Can I roll back to the stable one I have now if I have problems? Any chance of bricking the board with this beta?
