Vcore and cpu ratio

Hey, i have the K7N2G and i have some problems changing the vcore and cpu ratio in bios...
my cpu is a XP 2100+, it only boots with default vcore and 1.625, and default cpu ratio... if i change the cpu ratio it doesn't boot... what's wrong? what can i do to change de vcore and cpu ratio without crashing? the max fsb that i can use is 157 (~=2050Mhz -> 157*13).
I have OCZ-EL 256Mb

Wonkanoby....I think you are incorrect (but not 100% sure). I have a 2100 Tbred B and I don't have to use the wire trick if I put it in the EPOX...ASUS..... The nforce2 should unlock the Tbred B core, am I mistaken here?  I also had the same problem as the above user, but I CAN get the msi to unlock it at some lower multipliers. I'm a little confused why the asus and epox nforce2 boards unlocked my chip, but the msi will not. Any ideas?

  • Vcore and CPU Temp

    Hi Guys,
    Is it safe to run the CPU Vcore at 1.6V for long term day to day use ? I need this voltage to keep my system stable (i.e. running 2 X Prime 95 for over 24 hrs). On some fourms, I was told it is ok so long as the voltage don't go above 1.65V yet on another fourm, I was told never to exceed 1.58V. Not too sure which one to trust so will just try on this MSI fourm    
    Has anyone actually measure the CPU temp with an external temperature probe and compare the result with the temp. reading off the mobo (i.e. thru' corecentre, Speedfan etc) ? I'm just wondering how accurate are those temp reported by the MSI mobo ...  
    My current temp via Speedfan running 2 X P95 (100% load):
    CPU: 53C-54C
    System Temp: 32C
    Room Temp: 24C
    NB: 51C
    If I switch off my aircon, my CPU temp could shoot up to 57C to 58C at room temp of 28C-29C.
    I think the above temp is a bit on the high side (as compared to ASUS board) hence I'm questioning the accuracy of the mobo temp reading...
    Here is my rig:
    P4 2.4C @ 3.2 GHz
    MSI 875P NEO FIS2R
    Thermalright SP-94 with 80mm TT SF2 Fan
    Corsair 3200LL PRO 512Mb X 2
    Ratio 5:4
    RAM Timing: 2-3-2-5-8
    PNY FX5800
    2 X WD 120GB SATA HDD
    TDK DVDRW0404N Dual Format Writer
    Audigy 2 Sound Card
    480W Antec True Power
    Thermaltake Xaser III V2000A Alu Casing

    Ok, I've taken out the Audigy card, and no, I still need to pump up my Vcore to 1.6V to keep Prime 95 stable.
    If Vcore = 1.525V, 2 X P95 fails within the first hour.
    If Vcore = 1.5875V, 2 X P95 fails after 13 hrs.
    So I guess my mobo is not affected by the Audigy card

    But than again ... I need this card to play Need For Speed - Underground  
    Just wonder if the Audigy card is so power hungry that it draw so much current from the mobo that one need to increase the Vcore and Vdimm to keep things stable...
    With the Audigy card, my voltage settings are:
    Vcore: 1.6V
    Vdimm: 2.7V
    VAGP: default voltage
    DOT: Disabled
    MAT: Turbo
    Will see if I could maintain at default Vcore if i remove the card.
    Thanks for replying.

    I can get very stable overclocks with my 2.4C at much lower VCore and VDimm voltages if I just remove the Audigy card.
    I have to keep my VCore at 1.70V with the Audigy installed. My CPU is idle at 32-35 degrees, so I'm not too worried about it dying on me (plus, it's only a cheap 2.4C).
    Just to give you an idea, I'm running the following:
    2.4C at 3.0 GHz (250 FSB)
    MSI 875P-FIS2R (BIOS: 1.8)
    1GB Mushkin Level II (5:4, 333MHz @ 2-2-2-6)
    SoungBlaster Audigy
    DOT: Disabled
    MOT: Fast
    VCore:  1.70V
    VDimm: 1.85V
    VAGP:   1.70V
    Now, *WITHOUT* the Audigy card, the same system works stable at:
    DOT: Disabled
    MOT: Ultra-Turbo
    VCore:  1.60V (possibly even lower)
    VDimm: 1.70V
    VAGP:   1.60V
    I know it sounds hard to believe, but *Reilly* will definitely back this claim up. Just take the Audigy card out and see what your results are. ALSO, I have read postings in ASUS board forums that PCI slot 3 works much better with the Audigy than any other. Can't confirm that, though.
    Post your results!!!!

  • Question on FSB, CPU ratio and VCore

    Hi:
    I have been reading several postings on overclocking CPU. As far I can tell, people recommended increasing the FSB freq. in the BIOS until it cannot boot any longer.
    I have KT3 Ultra, Athlon XP 1800+, and DDR 333MHz.
     ?( How does changing the FSB freq. affects DDR freq? Is it 1:2 ratio? For example, if FSB = 133 MHz, then DDR is 266 MHz. If so, is FSB limited by DDR rated freq?
     ?( Does changing the FSB actually changes the clock signal feeds into the CPU?
     ?( Does changing the FSB only affect CPU? Does it affects the PCI bus?
     ?( What is CPU ratio? Is it an internal clock multiplier to the CPU?
     ?( How does CPU VCore affect the overclock?

  • Multimeter and CPU-Z Vcore readings vary

    hello again,
    Funny enough I got my digital multimeter connected to the motherboards Voltage Check Point to check it out.
    I have the P67A-GD65 and i7-2600K @ 4600MHz and my issue is that I set the Vcore to 1.345 manually, but the actual Vcore is 1.352V according to bios and CPU-z. However the multimeter is showing 1.360-1.362V.
    When prime5 is running the Vcore in CPU-z goes up to 1.392V at which point the mutlimeter is showing 1.403V!
    Why all those readings differ so much?
    Regards

    Why all those readings differ so much?

    a high end meter can cost several times the whole motherboard

  • MSI k8n neo2 and cpu vcore...

    Dear All,
    I just check out with core cell my vcore and i find it @ 1.5v ... but a64 .09 should have 1.4v? I also tryied to set vcore in bios at 1.4v
    but in windows i always find 1.5
    I check it with ntune and core cell...
    What happens?
    tnx

    Use cpu-z from www.cpuid.com to check the voltage .
    The mobo bios may still autodetect winchester to 1.5v , if thats the case change
    cpu_vid from startup to 1.4v .

  • KT4V CPU ratio

    Hi,
    few days ago purchased MSI kt4v mainboard. I have a question about cpu ratio settings in bios.
    These are the options MB offers me:
    14.0
    15.0
    6.0
    7.0
    13.0
    12.5/13.0
    14x and 15x at the top. But when i try to set 14X133, the real setting is 4x133 !! Same with 15x (5x133). So, these 2 settings don't work! CPU is unlocked, becouse i can use all other ratios! I updated BIOS to 1.8 and it is the same! :(
    Also i have a question about AGP: i have radeon 9000, but i can not choose AGP 8x in BIOS! I can only select 1x, 2x, 4x .... WHY?  ?(
    thanks for your answers.

    i'll assume you are running your ddr333 at ddr333.  if it's on auto then try setting it to spd and then making it 333.  then try setting ur multiplier to 10 and fsb to 150 and then put ur fsb up in increments of 5.  once it fails to post then bring it down one at a time.  default clock for xp1700 is 1.466.  10x150 will put you at 1500 and should be possible.  if you can make it to fsb 166 then stop and up your multiplier to 10.5.  then keep upping your multiplier until it fails to post.  upping your vcore might help.  i'm not really all the familiar ocing xp chips though.  i've heard sometimes you don't have to up the vcore.
    as for the radeon.  i looked for bios updates and unless you have a 3rd party radeon (ie. not made and shipped by ati) then you are probably out of luck with that.  i know most nvidia's are 3rd party anyway so they all have different bios versions.  best thing to do i guess would be to rma the card.  i'm sure if all radeon 9000's didn't work at 8x with the kt4 there would be lot more posts like yours.

  • Z87-G45 GAMING unable to enable EIST when changing CPU ratio

    Hi
    I need some advice please.
    The moment I change the CPU ratio using the +- my options for enabling turbo core and EIST gets greyed out.
    I get the option to se the ratio to Dynamic mode and have tried it but the CPU still does not throttle down multipliers in Windows even if idle.
    Have tried the following.
    Loaded BIOS 1.3
    Cleared CMOS left out battery etc.
    Still does not allow me to enable it.

    Quote from: Froggy Gremlin on 25-June-13, 00:47:21
    500/(128)/500/1024(A). Try with the Power Options in Windows set to 'Balanced'.
    I found my minimum processor power state was set to 100% restored that to default 5% and now it clocks down the mulit.
    Now the voltage only stays at what I specified in the BIOS, can I somehow control that by setting vcore to auto and using the offset to limit volts on 1.190V?
    **Edit**
    Installed the MSI Intel Extreme Tuning Utility and found a setting that allows me to put core voltage mode to adaptive and now volts are down to 0.695V
    Thanks so much for all the help

  • X79A-GD65 (8D) - Get stuck at 12x cpu ratio multiplier or 1200MHz

    Hi all.  Just wanted to see if anyone else observed this with the new X79 chipset motherboard and the 3930K or 3960X sandy bridge-e cpu.
    When trying to overclock the motherboard in any way
    1) CPU Ratio set to any number
    2) Per Core Maximum ratio / multiplier
    3) OC Genie II
    and then trying a CPU stress utility such as Prime95
    The CPU gets locked at 1200Mhz, or 12 x 100Mhz and never goes higher than that.  At the same time, the temperature sensors believe the CPU is locked at 91 degrees celsius.  So I believe on this bios version of 1.2 on the MS-7760 motherboard (X79A-GD65), it thinks 91 degrees is too hot, and never goes above 1200MHz.  I've also tried OC Genie and manual overclocking at bios version 1.1, and I cannot go over 1200Mhz.
    Only at stock speeds (no overclocking), with the 3930K, at full CPU load tests with Prime95, it does go to 3500Mhz, or 35 x 100, correctly.
    Right now I cannot overclock at all, whether with OC Genie, or manual cpu ratio multipliers.
    Tweaktown and HWBot and several other websites have observed this.  I'm running the latest 1.2 bios, and still get stuck at 12x.
    http://hwbot.org/forum/showthread.php?s=51e18bdfe400391d0955716a5c66343d&p=138647#post138647
    http://www.tweaktown.com/reviews/4423/msi_x79a_gd65_intel_x79_motherboard_review/index5.html

    Scratch that.  It was happy yesterday, but first boot of the morning today and back to stuck at 12x/91C.  Will changing other voltages remedy this?  I read something on a review website suggesting this was a problem with the actual 3930K/3960X chips, and not necessarily a motherboard issue.
    If I raise my cpu base clock from 100 to 125 and use a 36 multiplier, the machine forces the memory to run at 2,000 MHz, which according to the SPD shown in bios should be OK, but I couldn't get it to boot like that.  Is there anything I can change to allow the machine to work in that configuration?
    Edit:  Just read yet another OC review (this time on HardwareSecrets) and found the following:
    "The “correct” way of overclocking Intel CPUs with Turbo Boost technology is to change the clock multiplier that each core will use when the Turbo Boost technology kicks in."
    I just tried changing the core ratio limit for all six cores to 45, setting the cpu ratio to auto, and leaving the core voltage at 1.375V, and it seems to work again.  Boots into Win7, coretemp displays correct temperatures, and when I load the cpu using prime95, it hits 4.5GHz.  I will try setting core voltage to auto also so that the cpu doesn't stay at 1.375V at idle when not necessary.  I'd still like to OC the memory in theory - not sure how much boost I'd get by running the memory above 1600 MHz.  I'll be using this PC for some computational fluid dynamics, so every bit of speed I can eek out of it will be put to use.
    Edit 2:  Auto core voltage works, vcore drops to 0.840V at idle, and idle temps drop back down closer to room temperature (using an Antec Sonata Elite case with a Corsair H80 water cooler, so slightly less airflow than ideal but I have the case fans optimized for now by relocating the system blower fan to a drive bay and adding a 120mm fan in the lower drive bays pulling air out of the side of the case).

  • MS-1722 (GX720) BIOS 1.0H CPU Ratio

    I have a MS-1722 (GX720) with a Intel P8400 CPU.
    The original flashed BIOS is 1.0H. It recognizes the P8400 as 2.26GHz. However, the Ratio is shown as 6.5 Actual and 8.5 Max. The multi should be 8.5 Actual for the CPU to operate @ 2.26GHz.
    CPUZ shows the CPU operating @ 1596MHz, multiplier x6. Memtest+ also shows the CPU frequency @ 1596MHz.
    Windows shows the CPU operating @ 2.26GHz in General System Properties.
    I don't know which to believe? I'm leaning toward CPUZ reporting correctly.
    I have contacted MSI Tech asking about the available updated 1.0M BIOS and if it will correct the above issue. MSI replied that the updated 1.0M BIOS is for additional Quad CPU support, they did not comment if it would address/correct the Ratio issue I'm seeing with my P8400.
    I do not want to flash my BIOS if do not have to, especially if the BIOS update does not resolve my issue. Does anyone know if the 1.0M BIOS update has Dual Core CPU improvements?

    So, if SpeedStep is disabled and Power Scheme is "Always On", what is controlling the CPU step?
    Let me try to explain:
    When it comes to Intel processors and automatic frequency & VCore adjustions, there are three main CPU features that produce effects that look the same to you, but work in different ways:
    -> EIST (Enanced Intel SpeedStep Technology)
    This feature needs to be enabled in BIOS & within the operating system (by selecting a proper power scheme).  This is the plain and simple SpeedStep function that will allow the system to shift between different frequency points (by adjusting the multiplier) and VID points, depending on CPU workload.
    -> C1E [Enhanced or Extended Halt State]
    From the outside, the C1E feature will (just like EIST) cause multiplier and VCore changes.  However, this feature does not depend on Windows Power schemes, but will work even though the Alway On Profile is active and EIST is disabled.  The C1E function is also different from EIST, insofar as C1E is actually a CPU power or more precisely a CPU IDLE or Sleep state.  All processor core can enter this state independently, accompanied by VCore and Multiplier adjustion.
    -> Thermal/Overheating protection
    Intel processors based on the Core Architecture have a feature that will cause multiplier and VCore to decrease the lowest possible level (even & especially under full load) as soon as the processors core temperatures reach a critical level.  This enforcement of voltage and frequency reduction will help the processor to cool down.  If the temperatures keep rising because of a broken CPU Fan or very high environment temperatures, the processor will initiate a shutdown to prevent damage.
    Quote
    Is this considered the optimum operation?
    Yes, of course.  I can not think of one simply reason that would convince me that turning off these features is a better idea than enjoying their effects.

  • FM-A75IA-E53 + A10-6800K cpu ratio is locked

    Hi!
    As Russian's MSI forum is dead I'd ask here.
    New board FM-A75IA-E53 (bios 2.0) + A10-6800K + 2x4Gb 2133MHz GSkill Ares RAM
    Post, Boot Win7_x64 boot is Ok. But problem comes from Sun Virtual machine player.
    The virtual machine is failed to start due to virtualization is off. I have search in the bios but failed to find 'SVM enable' switch. Despite it was described in the manual. (hint: bios 2.0 'SVM enable' is absent)
    The bios was updated to 2.2.
    'SVM enable' switch appear with Enable/Disable options.
    Win!
    But!
    The CPU Ratio and Turbo Ratio is locked now. The lines to set the ratio is active (highlited, not dimmed as disabled) but on action on mouse click.
    Does it common error with this mobo+cpu+bios or it is my motherboard bug?
    Please help.

    You need to use +/- keys to change ratio settings not mouse click.

  • CPU Ratio not changing

    Hello,
    I have a K7N2G (Bios ver 3.7) with an XP2500 Barton CPU and any changes
    that I make to the CPU ratio has no effect. The FSB changes do stick though
    and I've set all bios options manually.
    J10 is in user mode and J11 is at 133/166.
    Any ideas?

    newer bartons are factory locked like the P4
    only the older ones can alter multipliers
    prior to week 39 or so last year
