Fuzzy Logic 4/Core Center - Changing FSB & Multiplier Settings

Just wondering if its at all possible to change the Multiplier settings or the FSB on the fly (in windows) - without having to restart and go into the bios to change them. I know that gigabyte has that feature for some of their boards.
The board in question is the K7N2-Delta ILSR
Is there a setting in the bios that needs to be enabled?
Thanks for the help if anyone knows.

niether is meant to be used with an nforce board

  • Sempron 2.4 cant change fsb multiplier

    hey i just built myself another computer with 2.4 sempron with MSI KM4M-V mobo... i think lol and i just updated the bios because when i go to frequency control etc in bios i cant update the fsb multiplier so the processor runs at the correct speed windows is only recognising the processor as a 1.33 anyone have any ideas? i updated bios with live update the bios is Award bios

    KM4M manual
    According to page 10 of that manual, the jumpers should look something like this:
    SW1
    |
    |
    SW2
    That *should* give 166FSB, if the manual is correct, there is a statement that V1.2 of the manual has corrected the jumper settings.

  • Fluctuating FSB/Multiplier

    Hi, i've recently purchased a K8N Neo4-F motherboard along with a x2 3800 toledo, and i'm having problems with the FSB and mulitplier fluctuating. I've been checking it in core center, and the core speed often drops or rises by about 200MHz as a result of the changing FSB/multiplier.
    I found a post on this forum with someone having the same problem as mine and with the same motherboard(and similar rig), and the suggestions were:
    Quote
    Set your power savings in windows to "always on" .
    Disable CnQ in Cell menu in bios .
    Click on the Cool'n'Quiet text in Corecenter and change from auto to user mode
    I've tried them all but it didn't work for me. I've noticed the problem seems to get worse when i've had the PC running for longer periods though, its fairly stable at first for awhile. The temps are fine all the time, never seen it above 40c, the vcore fluctuates by up to 0.07v, I assume thats ok but i'm not sure. I have a Hiper Type-R 580W power supply, so that shouldn't be the problem.
    Any suggestions?
     

    Well i'm kinda glad its normal, not something i'm used to. Like starting up a game to be told my system has changed all the time is a bit annoying. I did have it overclocked to 2.8GHz for awhile, which runs perfectly stable. But when the fluctuating started I got a bit concerned and put it back to stock speed... but it still does it 

  • Cool-n-quit/core-center

    in CnQ my cpu fan gives me an alarm above 3000 rpm's. Whatever I change in the setup, this won't stop. The fan speed alarm in set to 10.000
    Temperature is just 36 degr for CPU and 37 for system  
    Any thoughts?

    Hi everyone. As you can see I'm kind of a newb and I have some related questions. First off some background. I've done hardware installs, harddrive clean formats and swaps, etc. I was planning on building my own computer, but order one from cyberpowerinc.com. I haven't done a profile yet but will after this post so by the time you read this my system should be listed below. Anyway, in the BIOS I had cool and quiet disabled because in the manual it says to check serial numbers of chips before running it, and I didn't want to mess with pulling the heat sink , etc. to check my serial number. This morning while investigating a noise issue (high, varying frequency, buzz) I noticed in Core Center that it was related to CPU fan RPM (low RPM). I then found the program called speedfan, which allowed me to varify this, as Core Center wasn't real accurate. Using speed fan I was able to run the fan at 100% and got no buzzing. Below 70-80% I did though. I then found this thread and realized Core Center could do this (by clicking on Core Center) in another thread. So is the Cool and Quiet mode in Core Center the same as in the BIOS, because I thought if I disabled in the BIOS it would be disable, come to find out Core Center was running it (and causing the bad noise when the fan cycled to low RPM), it wasn't however slowing the CPU speed.
    So basically, I hate the buzz at low fan speed, can I just run my fan at max through Core Center? Is there another program that will allow me to run a min fan speed, but cycle say from 100% to 80%? Is it even worth that cycling if only down to 80%? Should I just set it to max or 7/8 manually? Are the BIOS and Core Center Cool and Quiet settings related?
    Any info you think will be useful to me, please let me have it. Thanks.

  • DKA790GX Platinum, have problem with changing FSB in Dual Core Center

    Hello guys, freshblood is here,
    I change fsb in Dual core center, but unfort.  core temp and CPUZ don't reflect any changes.

    I agree.  The BIOS gives you better control with better options.

    Dumb MSI Dual Core Center.  It is not the best tool ever developed.  Use the BIOS for overclocking your system.

  • 875P Core Center FSB 200?

    I apologize if this is a stupid question, but Core Center doesn't exactly come with a help file. I have the 875P mobo, 1 gig Kingston PC3200 CL3 in slots 1 & 3, Intel 2.8 cpu with 800 mhz fsb. My question is that when I open Core Center and pull out the left tab, it says the FSB is running at 200 mhz. Can this be right, or am I just missing something. I do remember that the bios recognized the memory as DDR400, so everything should be ok? Could I have something set up incorrectly?

    You're running 800 (200 times 4 :D

  • FSB differs in core center and BIOS...

    I know my FSB is set to 200 (the default value) but on CoreCEnter (lattest version) it shows 203... I'm not in a mood to make OC before getting rid of this stock cooler (but that will not be for now) so I wanted to put FSB at 200, I know the differecen isn't much and the system is runnin fine but I simply don't want it...
    I have 865PE Neo2-LS and I've disabled DOT in the BIOS (1.5). Do you know what's the problem?
    By the way, I just clicked "default" on core center, on the fsb and voltages menu and the CPU just locked-up and a loud sound like PPIIIIIIIIIIIIII wouldn't stop... I rebooted and worked fine but what's the problem?

    What you are seeing is the dynamic overclocking feature. If your Frequency setting is set to anything other than "disabled" Core Center will attempt to find an appropriate clock setting for you, based on processor demand and processor temp.
    I prefer this to traditional overcocking because it only "kicks in" when I need it.

  • Neo2 defaut FSB frequency , live update and core center issues

    Hi,
    This is the point : i bought a brand new 915P Neo2 last week,
    out of the box results : Windows XP SP2 install is OK right
    now, Graphics Card is working properly but the system is
    still unstable !
     --> I decided to install MSI core center but while running
      pc freezes !
    ---> tested MSI live update, packets download is working
     but the tool is still unstable and pc freezes .... while testing system...
    ---> tested a small utility (third party) from intel website
    to compute P4 target and actual frequency
    this tool reports that my p4 is running at 3.24 Ghz,
    I double checked and found that defaut FSB was set to 810 Mhz
    even after hardreset and bios safe mode, CPU is running at 203 Mhz * 16 = 3248 Mhz
    I really dont understand why reset value has been set to 203 Mhz ?? why not 200 Mhz
    so MSI 915 P  defaut setting is 1 % overclocking strategy ?
    the bios setup is not really taken into account ??
    have you ever pointed out this problem with defaut frequency ? is this a problem ?
    what is your opinion regarding MSI utilities ?
    I have a lot of random pc freezes, too many for this board !
    all advices are welcome !!

    I don't usually recommend bios updates, but you should seriously consider it if you can get the board to run stable.
    Test your ram with  Memtest86. This should give you an indication if you can do a flash from DOS, plus it will test the ram for you.
    Try setting your FSB to 201. On the 865/875 boards that will hold the setting. 203 is typical of MSI and other manufacturers, but it really isn't high enough to be considered overclocking, and certainly isn't high enough to cause problems. But it keeps them in the race with the others when the reviewer's determine which board is best by looking at the decimal places.
    You don't list your power supply data. Power and ram are the usual culprits, with heat being another.

  • Dual Core Center listing varied FSB in vista

    I've had it list the FSB as 467 and 1000, and I don't know if it should be doing that or why it's doing that. When I ran it in XP the FSB was always 200

    Quote
    or why it's doing that
    The first explanation that comes to mind is the usual one:  Dual Core Center is far from being the most perfect, flawless, accurate and compatible application.  The second explanation that can be added to the last one is:  Vista is not exactly the cream of the pie either.
    If you have more questions, it would probably not be a bad idea to give us some info about your system (read the >>Posting Guide<< first) and tell us which version of DCC your are actually using.  Another important thing you should not keep to yourself, is your Vista Version (32bit or 64bit).

  • I searched and searched (fuzzy logic 4)

    Hello!
    Right now i was reading for over an hour and i cannot find the right answer about fuzzy logic 4
    I used live update to get the most recent drivers for my mobo msi 845 pe max2.
    (just to be complete I have the HT option in the bios while having a P4 2.4Ghz, for those who want to know, bios 1.20).....
    My problem:
    I used the "auto" function in fuzzy-logic and waited 3 minutes, the FSB is boosted to 164. Than the system hangs and restarts. (thats normal right?) the cpu-temp is 64C when it hangs..
    then after the reboot, nothing has changed and the fsb is back to 133???
    What is wrong? how can i overclock my system with fuzzy logic??
    Sander

    I would NOT use Core-Center Either with your Board, as since it is a 845 Series, I dont Believe that you even have the "Core-Cell" Chip on your Motherboard ..I suggest that you use "Speed-Fan" as this seems to be the Utility that Most of the Members have Success with, and if you want a Utility to Overclock your FSB with, Download Clock-Generator, at http://www.cpuid.com  .....Sean REILLY875

  • How to run Fuzzy Logic 3 on win xp?

    hello!
    so, why can't i set fsb from fuzzy logic 3 ?? (on win xp) ?
    is there any hack to do?
    or should i install win98 ?
    p.s. thanks for any answer.

    As PoRsChe said you could use core center but I always liked going to the BOIS to make my adjustments. For me it seems to work better.

  • KT3 Ultra2-R ... Can't change FSB beyond 100

    Dear all,
    Just got my KT3 Ultra2-R with an Athlon XP2100, upgraded to 5.7 AMI BIOS, worked great, then made some changes to CMOS (forgot which ones), then couldn't boot.
    When I finally booted and went to CMOS setup, it would not let me change the FSB to anything other than 100...that is, no options on the FSB when I hit enter (shrug).
    Now, my system recognizes the CPU as an AMD XP 1500...blah. Tried everything...resetting CMOS with jumper, took out computer battery, replace 350 SmartBlue PSU with 400 Watt PSU, replaced Heatsink/cooler with better one, wiped contacts, nothing...it's not the temps, because my case idles at 29C chassis and 36C CPU temps.  Even reflashed back to BIOS version 5.6, and still no go.
    When I do "performance" settings in CMOS, it will give me 133 FSB, but my system will now be unstable. Weird thing was, before this "event", performance setting put it at 166 FSB :(
    Anyway, my comp isn't dead....it just won't let me change the FSB.  I called up ABS Computers where I bought this, and they said they are not responsible for damage caused from flashing BIOS...blah, whatever.
    I just put out an order for an Asus A7N8X Deluxe motherboard and joined the NForce2 bandwagon, but if someone could give me some insight into what I could do about my motherboard, besides hang it on my wall, I'd certainly appreciate it.
    Here are specs of my system:
    MSI Kt3 Ultra2-R
    Athlon XP2100
    Geforce2 video card
    soundblaster 5.1 Live
    WD 120 Gig and WD 60 Gig
    Liteon CRWD
    Sony DRU-500AX
    Q-Tech Quiet PSU 400 Watts
    Nexus Heatsink/Fan
    Windows XP Home

    Thanks for the reply, but while checking out the other problem with the KT4V / Athlon 2400 Clock Speed Problem (above) who couldn't set his FSB beyond 100, but when he set it the multiplier to 12.5/13, he gets a 20X multiplier when he goes into Fuzzy Logic.
    Well, guess what, I did the same thing (set my CPU multiplier in BIOS to 12.5/13, and lo and behold, I go into fuzzy logic, and my AMD XP 2100 is recognized as an AMD XP2600 running at 2000 megahertz...now someone explain that to me! I even check with SiSandra, and yup, it's seeing a 2000 megahertz processor. I even ran the benchmark tests on SiSandra, and it's on par with that processor.
    However, my FSB is only 100, and thus, my memory benchmarks are about 25% below the norm for my DDR333 RAM chips (i guess because they are synchronized with the FSB, and probably running at 200 then).
    Anyhoo, i'm tired of trouble shooting and figuring out what the hell is going on.  The comp is extremely stable at 2000 megahertz at 100 FSB...don't know what else to do...so installing new motherboard tomorrow and report back later.

  • Fuzzy Logic 4 help!

    How do I use Fuzzy Logic 4??
    I can install it, I can run it but I am buggered if I can actually change anything, all I can do is look at temp, voltage, multiplier, fsb speed and CPU speed.
    I thought this tool was to enable you to manipulate the CPU speed??
    I have a K7N2-L mobo 2100XP (TB 'b') CPU and using win XP home.

    How do I use Fuzzy Logic 4??, you ask...
    The short answer is: you can't. It doesn't work with the nForce2, as MSI makes clear.

  • Can't change FSB or anything

    I have been trying to oc my 2200 to get the most out of it that I can.  I tried the wire trick a while back but I ended up bending a pin which I fixed.  After that I never oc'ed my cpu.  I tried the other day just to raise my FSB but had no luck.
    For some reason when I raise the FSB nothing happens to the cpu.  I had the FSB at 290 but the cpu was still 1800mhz in bios, core center, and windows.  Im pretty sure you can raise the FSB without unlocking the cpu.  I thought I had before.  Now I cant for some reason, and I dont know why.  
    What am I doing wrong?  How come the FSB wont go up and change my cpu clock?  Any suggestions?
    Thanks.

    Hi, thanks for the tip. I changed the fsb/ddr ration to 1:1 as you suggested and upped the fsb to 140 last night (multiplier set at 7 in the bios) with Vcore left at standard.  WCPUID showed a clock speed of 2100 with a multiplier of 15. The cpu temp is now around 48c, and system seems to be stable.
    I will try upping it a bit more tonight, but a jump of 300 Mhz over the standard clock speed seems pretty good to me.
    The only thing that is bugging me is that I can't up the multiplier from 7 in the bios, even if I go at 7.5 with a fsb of 133 the system won't boot, even when I up the Vcore to 1.8v. Also 7 is the lowest I can go (I get options from 7 to 13.5).  If you know why this might be (do I need to unlock the cpu?) or have any other tips for oc'ing this system I'd be grateful.

  • Core Center Problems & General Questions added

    On boot up after installing core center on my PC, I get warning messages telling me that core center doesnt have the correct drivers installed, and that core center is not compatable with my motherboard.
    I just bought a MSI K8N Neo4-F ... any suggestions?  This doesn't seem to be a common problem and I can't get any answers anywhere :(

    After the proper bios adjustments and correct settings i can use corecenter to reach the maximium overclocking setting for this tool.
    In bios i do have to set vcore at 1.45 and HT at 4x , disable agressive timings.
    This way will lead to a fsb of 222, for my memory also without changing the timings leading to a 6600 score in sandra for memory.
    My cpu will clock 2666 then.
    Also i have to overvolt through corecenter for cpu and memory,both maxed out giving 2.85 for mem and 1.58 for vcore total.
    Now i'm not running this since i don't need the extra heat and my games don't require it either,yet.
    And i can run my cpu higher also,but that's not the issue.
    It's a way to see with which settings you get more performance without messing up the bios.
    Finding your way through it you can then set it in bios and forget about corecenter.
    See it as a first step,because after that you can adjust memory timings to get more fsb over the 200mhz. thus finding a balanced setting that will give the most speed,because setting timings too loose will not always result in faster performance even if you can clock the mem higher.
    Finally,you can also use clockgen to find your limits.This tool let me set the multiplier also to max out the cpu without compromising the memory.Also keep in mind that different cpu cores will give different results,you can't compare settings with different hardware after all.The venice core is a nice cpu for adjusting fsb settings which is for me a simple multiplier,also the memory divider on my board let me set a very high fsb if needed.Again,this is now a simple multiplier,it means nothing if i have it set at 230 or 340,i only have to bring down the cpu multiplier then to stay in spec and use the proper mem divider.
