Increase in FSB vs Increase in Multiplier

is there any difference in performance ? by this two ?
FSB : 100
Multiplier : 30
Core Speed : 3000Mhz
or
FSB : 200
Multiplier : 15
Core Speed : 3000Mhz

As you have an AMD system it makes a huge difference and what has been said before is incorrect. What you call FSB is the reference clock (BCLK) which all other clockrates are based on (front-side bus is an ancient technology on AMD systems and doesn't exist for years). Overclocking the reference clock can help to really optimize any oc and get more performance gain than sheer cpu clockrate increase would allow. Of course it takes way more tweaking to elaborate stable/optimal results.
Check this FM2 oc guide that will also help to understand the basics of overclocking your very similar FM1 system: http://www.ocinside.de/go_e.html?http://www.ocinside.de/html/workshop/amd_fm2_overclock.html
Still be aware that neither your cpu nor your mainboard are really meant for oc so there might be just little oc possible.

  • Cannot Increase CPU Multiplier - Help?

    Here's my problem:
    I've unlocked the CPU Multipliers on my AMD XP-1600+ by
    connecting the L1 bridges.  System boots & runs OK with
    stock (10.5 x 133) multiplier value (I'm running that right
    now).  I can also reduce the multiplier (10 x 133).
    When I try to increase it (11 x 133) the system won't
    POST; I have to power-off/on (then I get to re-enter ALL
    BIOS data). javascript:smilie('X(')
    Mad
    Can anyone give me a clue what's wrong?  Have I blown
    the unlocking; will my mobo just not support increased
    multipliers...??  I've had the system running stable @ 148
    Mhz FSB before unlocking it (and at least 140 Mhz after).
    Here is my H/W setup:
    KT7266-Pro (6380) Ver 1.0 mobo with Ver 1.9 BIOS
    Ver 4.43 4-in-1 Drivers, Ver 30.82 Detonator.

    Thanks for the reply wonkanoby - yes, I did;  first cleaned
    out the 'ash' then filled them with JB-Weld.
    This is the 2nd time I've tried unlocking.  The first time, the
    BIOS reported clock speed as 1200 Mhz no matter what I
    did.  Well, I hope the 3rd time does it - that's a bloody
    tedious job, even with a 5x 'hands-free' magnifier.
    BTW, what do you recommend for removing rear-window
    de-fogger paint?  I've been using acetone.

  • Increasing FSB multiplier on a c2q q9550 with a p45 neo2 mobo

    Is it possible to increase the FSB multiplier on my BIOS? I can only increase it until x8.5, coz im planning to OC it by increasing the multiplier and decreasing the FSB. My FSB right now is 450 MHz x 8.5 = 3.83GHz
    Specs are on my sig
    any help are appreciated. Thanks!

    can the i7 920 raise the multiplier to it's stock multiplier?
    Quote
    Well [...], yes.
    Let me be somewhat clearer on this:
    This statement is still true, even for Core i7 processors:
    Quote
    You would need an 'Extreme' edition of CPU to raise the multi.
    The CPU Ratio of the i7 920 can raise above x20, but only to a certain extend (within the limits defined by the Intel Turbo Boost Feature for this processor).  That means x21 is possible, and maybe x22 (I am not sure).
    To be able to raise the multiplier to (let's say) x33, you still need an Intel Extreme Edition processor.  ---> Like this one:

  • OC on P43-51T (able to hit 400 fsb using x8 but can't hit 400 fsb using x9)

    Hello,
    I was wondering if anyone can explain why my board is rock stable at 400 fsb using a x8 multiplier (q6600 go) but I can't seem to hit 400 fsb using a x9 multiplier. Really hoping to OC my chip to 3.6 Ghz (400x9) versus 3.2 Ghz (400x8). I was only able to hit 370x9 (3.3Ghz) when using the x9 multiplier. All settings have been tested stable @ prime 95, small ftt, large ftt and blended.
    FYI: My ram is set to 1:1 for both scenarios when I tried tweaking with the board. Currently the volts for both settings (400x8 and 370x9) sit at 1.352v.
    Also, I have been able to hit 3.6Ghz on a x9 multi on my old 650sli v2 (using 1.42v) and I'm assuming this board should be better than this. I tried increasing volts (even set it to 1.42v but not stable) to no avail. The chip is fine since these 65nm chips have a max 1.55v rating before burning them.

    I got a little excited and went straight to my results!
    First I tried the x9 multiplier and set it to 101, and it was a no go, I was still stuck @ the 370 fsb wall (for x9, 400 for x8 multi in my case). I then tried 102 then tested (still couldn't get past 370) and then jumped to 104 and did the same thing. At 104 Mhz with a x9 multi I was able to boot up to windows but it would BSOD, with 101 and 102 it wouldn't even post. DIdn't try anything after this with my x9 multi.
    I finally decided to try the x8 multi and at 101 and 102 to no avail, I was still stuck at (my fsb wall of) 400fsb with a x8 multi. I jumped to 104 (got impatient) with a x8 multi and just OCd the fsb incrememntally to 425 Mhz. I tried going past 425 but it was not sable at all, I would post and boot into windows then get a BSOD.
    I even tried Ocing straight to 108 and directly to 120 (just said what the heck let's try it) but the resuls were the same for me it wouldn't go past 425 fsb with a x8 multi.
    Apologies for not going through the PCI-E frequency and just decided on some random numbers to use, I was just too excited and tired at the same time that I wanted to shortcut some things.
    I think what's holding me back though are mems, It's a Kingston Value ram and at its current settings (450) it's overclocked to it's limit I believe. I will try to find some good mems or borrow some from a friend to try and see if I can get over the hump and continue to push my fsb.

  • K7T Turbo2 BIOS CLOCK MULTIPLIER

    I've got a K7T Turbo2, ATHLON XP 1700+ with the latest BIOS Update.  MY Power Supply is 350W, ATI RADEON 9000, and 512MB SDRAM.
    I removed the jumper on the board so the FSB is 133 x2.  However, I've tried increasing the multiplier in the BIOS and it seems to have no effect.  I even took it up to 15, the max.  When the machine boosts and I open either FUzzy Logic or SiSoft Sandra, both still say my clock mulitiplier is 11, and the speed is still the same.
    Any thoughts?  I'm currently getting 1460 mhz from the processor.

    Sounds like a Palamino with locked multi. Only real way to verify - remove heatsink, and give us all data printed on core.
    OR, you could d/l WCPUID (see Google for d/l site- tiny d/l)and give a screenshot which should show the model of the CPU.

  • KT6 FSB and Vcore

    I've just updated the corecenter software to 1.5.8 version. and I apply the auto overclocking option.. my XP 2600+ is running at 2.33 Ghz = 183Mhz (FSB) x 12.5 (multiplier) and the vcore is 1.65.
    I want to know if I want to overclock my cpu, I must change the vcore voltage. Also I don't know if is good to keep my cpu at 1.65 v or change it.. please suggest something about that.
    Thanks

    hi,
    To be honest you only need to increase the voltages if it wont boot with the overclocked settings. So if it works leave it.
    My XP 2500+ runs at 2.2GHz fine at default 1.65 voltage.

  • Overclocking 3200xp by multiplier problems

    Hi There,
      I've just installed a 3200xp 400fsb into my K7N2 Delta-ILSR board, after reading several reviews online they say that the 3200 is not locked and by increasing the multiplier from 11x to 12x obviously gives you nice overclock. I can go into the Bios and change the multiplier to 12x, then save and exit but when windows restarts and I check the multiplier within windows it still says the multiplier is at 11x although the bios still has it at 12x, just wondering if anyone has any ideas what's goin on and can I change the multipler.
       I've also just tried altering the fsb but when it gets past 205 it all becomes unstable, even when running VCore of the CPU at 1.80v, the voltage of the DDR at 2.7v, and the AGP voltage at 1.7v., any other ideas of how to overclock this chip would be very welcome.
    Thanks,
    Paul.

    the multi is locked on new amd xp chips, u can only resort to raising fsb, try upping vcore and vdimm, and loosening timings on the ram
    edit: i noticed your ram, its not the better of the overclocking ram, best ocing ram out right now is some of these:

  • P7N Platinum Can't get FSB speed over 350 mHz

    Trying to overclock a bit but when I use BIOS, won't let me change multiplier unless some speedstep is turned off.  I cant find where in the BIOS I have an option to turn it off.  I am using BIOS ver. 1.3.  Also, when I use Dual-corecenter with windows running, I can get FSB up to 350 MHz and all is stable but will not go above 350 MHz...I select 400 in the dropdown and it just resets to 350.  So, if anyone can let me know how to turn off the safestep and/or how to increase the multiplier in BIOS 1.3 that would be great.  I have heard that I can go to 3.7 GHz with Wolfdale 3.0 GHz E8400 and stock fan & heatsink.  I have an Antec air-cooled full case with plenty of airflow.  At 3.150 GHz, CPU temperature is only 71F when surfing or playing music and doesn't go above 83F when playing my most intensive games.  Answers to these three questions would be greatly appreciated!! Thanks!
    Bob   ???

    The automatic shutdown point of your CPU is somewhere around 90-100°C (Core Temperature).  The processor will automatically underclock and undervolt itself if the core (!) temperatures are approaching this point. That is how you know when the processor definately running too hot.  50°C is a very safe but also rather conservative threshold.  If your CPU approaches the 60°-70°C area and even exceeds 70°C under full load (core temperatures), that is when you should really start to work on better cooling.  However, 60°-65°C is still a rather safe range.

  • Can't get fsb to 200??

    Ok, after some tooling around, I finally unlocked my cpu...It posted at 933Mhz the first time so I know it worked....After changing the fsb to 200 and multiplier to 10, it wouldn't even post, no beep, no nothing...If I back it off to 12x166, it runs like a champ(my highest stock 2.0G cpu score yet!!)...Anyway, I have the RAM set to 1:1 and am using timings 7,2,2,2.5....When I set the fsb to 200 the memory timings change to 8,3,3,2.5...I believe these are more relaxed and should allow smooth operation at a 200fsb?? Has anyone else had this problem?? How can I fix this? I vaguely recall seeing something about a problem with the 10 and 10.5 multipliers on this board...I can't for the life of me remember where or when, but is this my problem?? If it is, will something like 9x222 work instead?? I'm afraid to go messing with it any further, it runs great now, but I just know it could be better...Thanks for the help, and any advice is appreciated...
    BTW, I still can't get the %$#*& front side USB to work...Cut which wire? 9 is already empty? Which one goes in my ear?? Man, I'm lost again...Silly

    See, Thanks, I didn't know about having to raise the Vcore for an increased fsb...I haven't touched that yet...I will try setting it to 1.7...Right now it is at 1.65, should I increase only slightly at first and try, 1.68 maybe? Also, sorry about the gaming lag!! I play a LOT of BFV and know how frustrating lag can be...I will let you know what happens when and IF I get there...Gonna try it with different memory timings(suggested by Wonka) and raising the Vcore slightly...Is there anything else I should be aware of?? I'm gonna give this a try tomorrow after work sometime...I'll check this post before I get started and after to let you guys know what happened once I have tried it...
    BTW, Are you getting lag in Single player games and Multiplayer, or just one or the other?? A little lag is to be expected from time to time when playing on-line..And is it all games, or a specific one or two??  Silly

  • 200MHz FSB when I want 800MHz

    This is probably a rather simple/stupid question but I have an 800MHz FSB P4 and 2 banks of DDR400 and therefore thought I would get a FSB of 800MHz.  However, when I check CoreCentre it records an FSB speed of 203MHz, multiplier of 13 giving the CPU speed of 2637MHz.  What am I doing wrong, if anything?

  • Changing the Multiplier in 420D PRO mobo

    basicaly my CPU is an unlocked Athlon Thunderbird running at 1.4 Mhz/266 FSB with a default multiplier of 10.5
    Am trying to change the multiplier from the default to 11.5 through the BIOS and it doesnt make any changes when i reboot.
    am sure that my CPU is unlocked cause i tried to overclocked it on my older mobo (EPOX EP8k7A+) and worked fine!
    i have the latest BIOS version 2.60
    got any ideas?
    pls help me out!

    im going from memmory as we dont have many
    overclockers here but i seem to remember people moaning when 2.6 came out about this
    im sure 2.4 works try that

  • Bios cpu Fsb Speed

    by default this is set to 200, why is 200 the FSB, or is that multiplied by something?
    also, it says it can go to 280, is this overclocking?
    is it best to leave it at 200?
    also, last night my computer was turning itself on???i dont have a set time to power on and there is no wake on lan option, how do i stop this from happening?

    Raising the FSB = overclocking. If you take it to 280 (the standard multiplier is 10), you get 280 x 10 = 2800 = 2.8GHz. Now, if I were you I wouldn't try this "at home" unless you have a nVentiv Promethia cooling system or Vapochill, or something similar.
