Low Voltage

We have 2 Apple XServes and one of them is reporting Low Voltage on the CPU 1 Vcore at 1.21 volts. The second Vcore is reporting normal at 1.27 volts. The other XServe is reporting a normal voltage of 1.27volts on both Vcores.
Is this anything to worry about and what exactly is going? Any help or thoughts would be very much appreciated!
thanks in advance,
Bill

The word from Apple on this is that the voltage core thresholds are somehow hardcoded into the CPU itself. If you compare one box to another, the thresholds can be different.
While your number may not be out of spec for the G5 processor, it is possible to be out of spec for the thresholds preset in the processor. (Extremely annoying, no?)
My experience with this required that we swap out processors to fix the problem. Little else we tried would fix it, as there is no way to change the thresholds that System Monitor sees.

  • Getting low voltage from the Macbook Pro Case

    I'm getting low voltage throughout the casing whenever the brick is plugged in my 2011 macbook pro 13".  I can run my fingers across the case and get the 60hz hum from the ac current.  Pretty neat effect, not sure if it's totally safe or not.  I tried plugging it into several outlets and changed the surge protector, with no changes happening.  Anyone else getting this issue?  Thank you for listening!!!

    I have exactly the same problem. How did you fix it?
    Is it magsafe adapter issue?

  • Portege R930: DDR3-1600 SDRAM Low voltage (1,35) or standard voltage 1,5

    Hi again,
    Just wanted to know if the two sorts of DDR3-1600 SDRAM RAMs (one is called low voltage memory) that are available on the market are compatible with my Portege R930 i7 Toshiba?
    Thanks!!

  • Low Voltage FB-DIMMs

    A question for Apple:
    Is the new 2008 Mac Pro compatible with low voltage (1.5V rather than 1.8V) FB-DIMMs?
    For example, these: http://www.acmemicro.com/estore/merchant.ihtml?pid=5236&step=4
    (I do realize that an Apple approved heatsink would have to be added).

    Why take a chance? they don't mention ECC. There are other places with good prices.

  • Low Voltage at "CPU 1 Core"

    Our Apple Xserve is reporting (warning) Low Voltage on the CPU 1 Vcore at 1.21 volts. The second Vcore is reporting normal at 1.27 volts. The amusing is the warning is going out by e-mail when Retrospect is making an backup.
    Is this anything to worry about and what exactly is going?
    Please Help!
    Thanks to you

    Do you do anything else that uses both processors? I am just curious as to why only with Retrospect.
    Yes, a low voltage warning is something to take seriously. Most likely your CPU, MB or power supply are about to take a dive.

  • PWM-520 low voltage problems

    Hi all.  I am having a problem with an FP-PWM-520 module and I'm hoping that someone can help.
    I have a Fieldpoint system with two FP-PWM-520 modules in positions @7 and @8.  The two modules are powered by a dedicated 24V supply.  One module works properly but the second module does not output enough voltage to run our equipment (~4-6V per channel at 100% instead of ~24V).
    I measured and got 23.96VDC across V and C.  I tried swapping the modules to see if it was a problem with the terminals but the problem moved with the module.
    Is there a configuration setting that i missed or is the module toast?
    Thanks,
    Dave

    Hi Janell.  Thanks for the reply.  Here are the clarifications you are looking for.
    1. The power supply is connected to the V and C terminals at postion @7 in the Fieldpoint train.  The V and C terminals at position @7 are then jumpered to the V and C terminals at position @8.  As originally connected, the two PWM modules share the same power supply.  This power supply is used exclusively for the two PWM modules.
    When I say that I swapped modules it means that I took the two modules and switched their position in the train (ie: the module that was at position @7 was moved to position @8 and the reverse was done with the other module).  When I swapped the modules, the low voltage outputs followed the module that I suspect has a problem.
    2. I did try isolating the supply to each module.  The result was that one module worked properly and the other still put out the low voltages.
    3. I will try this in the morning.  Is it possible that the PWM modules are interfering with each other?
    Thanks,
    Dave

  • Low Voltage and Audio (AC97) Lost in Game

    Hi, someone please help me. i have search the forum with no luck.
    i have installed the monitoring software provided with the msi cd and during gameplay, the alarm goes off in win98 (i don't play game in xp). the voltage (most of it) falls below the normal level. the 3.3v fall to around 2.8v. sometimes, the pc just went off without warning. is it the psu problem? how to check? is it harmful if i keep using my pc ignoring the alarm? are there any other reason for the voltage to drop other than faulty psu? fyi, i have 350w psu with 2 hdd, 1 cdrw, 1 fdd, 1 agp, 1 pci, 1 thumb drive in use and 1 casing fan.
    another problem, my audio come and go in most game. it all started after i install directx9. i try directx9b but the problem still there. my sound driver is up to date (v3.59). i think it has nothing to do with psu problem bcoz this problem exist long b4 the low voltage problem. last time, i reinstall everything and use only directx8.1 to solve this. i don want to do this now. i found similar problem in this forum but there are no conclusion. anyone know how to solve this? or maybe i can downgrade directx9 to diretx8.1?
    Thanks, in advance.

    12V/18A. it is cheap, so it might not be the best psu. i play all kind of games in 98. just don't want to mess up with game in xp. when it happen like my sound problem, i reinstalled everything. if i use xp to play games, there would a lot to do.
    i had installed mbm 5 and here is the lowest/highest voltage recorded. 2.66/2.96 4.81/4.87 11.19/11.55.
    Anyway, the sound problem seem ok after i change something in bios. something in ram timing. i set from auto to manual without knowing the function. what dhould i set for the best setting for this timing?

  • Low Voltages - Should I Be Concerned

    My positive voltages are reading a little low, but I don't know if it's enough to be concerned about.  I've never really paid much attention to them before, but since I want to do some OC'ing, I'm noticing them now.  I'm using a Antec TruePower 330w which came with my case.  I thought it was supposed to be a good PS, but now I'm not so sure.  Also, the voltage readings differ between Core Center and the bios PC Health readings.  Here is what they show:
    Core Center:  3.3v =  3.47 - 3.48,  5.0v = 4.87 - 4.89,  12.0v = 11.66 - 11.72
    Bios:             3.3v = 3.21 - 3.25,  5.0v = 5.0 - 5.06,  12.0v = 11.68 - 12.01
    The readings fluctuate between the numbers shown.  Do I have power supply problem?  Will I if I start to do some OC'ing of the system and video card?  And finally, which readings are more accurate, the bios or Core Center?  Thanks.
                       

    There will always be some fluctation even with the most powerful powersupply, depending on idle / load mode, what hardware, MoBo, what bios / software used etc etc. However the critical levels, according to the ATX std.is
    11.40v min. on the 12v
    4.75v min. on the 5v
    3.14v on the 3,3v
    In idle mode, even a bad PSU could hold the values quite good, but it´s differant under a longer period in load mode.
    To find out what values you got under load, you can use speedfan ( or other alike software) , which gives you min./med./max-values on the differant lines.
    Speedfan is a good alternativ to Core center for temp / voltage control.
    https://forum-en.msi.com/index.php?topic=28332.0
    If it´s a newer truepower 330w model, you should have 22amp on the 12v line, which should give some possibilities for OC with stability. If it´s an old model that have less then 20amp, you could be on the limit.
    D/L and use 3dmark03/05 and prime95 to check stability.
    https://forum-en.msi.com/index.php?topic=33850.0
    OC stability is not only about a good psu, it´s also a lot of bios settings that needs to be done.
    The most important ones would be mem.voltage / agp/pci lock and disable spread spectrum.
    Max RAM speed depends on RAM quality, if it handles 1:1 OC or if you have to lower speed to 333mhz (5:4).
    You also could add your spec./sig with what Radeon model you´ve got.

  • [Athlon64] Low Voltage Problem

    Just built a new box and ran MSI PC Alert to check voltages, temps, etc.  The monitor program reported all temps, fan speed and voltages as good except 3.3v was reported as 0.56v!!!  I immediately checked the Bios and found the following voltages: Vcore/1.5v  12v/11.9  5v/4.9  Batt/3.0.
    Since I couldn't find a phone number for MSI Support, I sent them a request form listing my concern. No response for 4 days.  Sent Antec a request and they advised me to check their power supply with a volt meter which I did.  The voltages were right on.  The system ran very stable for a few days then started having the BSOD.  I continued to monitor temps, fan speeds and voltages and all appeared fine with the exception of the errant 3.3 v which is steady at 0.56.  The BSOD may be related to my US Robotics wireless lan as the common denominator seemed to be when accessing the internet.  Updated the driver for this devise this AM and haven't had a problem since.  My main concern is the low 3.3v reading.  Any suggestions on what I can do to bring this reading into specs would be appreciated.

    Hi,I also have a the same problem,3.3V shows as0.56v with my k8m neo-v
    But its working solid as rock,no other problems
    I installed PC Alert3 and 4 ,speed fans,and EVEREST to check it out.But All of them showed 0.56V LOL
    No replies from the MSI support as usual.
    First i thought it was a BIOS problem before I saw your post,because my sempron+3000 cannot use
    cool and quiet . Waiting for the BIOS to support cool and quiet. 64 2800 is OK.
    I checked with different PSU(much powerful) units and diferrent combinations of memories(all tested with mem86)
    I still dont know if this is a hardware or software problem,I am gonna try with WIN2K not XP and
    find out whether it still shows 0.56V.
    I know that if its really 0.56V ,it will not even boot.I am thinking its a sensor problem of the mobo
    since everything is working fine,only 3.3V problem.

  • DAQ of low voltag signal

    Hello,
    as I´m quite new to LabView and DAQ this question is hopefully easy to answer.
    I´m trying to read a voltage signal from a device referring to a temperature ( 10mV = 1°C). When reading the voltage with my DAQ-Card with a rate of 1000 Hz, I see the voltage I expect (300 mV) and peaks with 2,5 V and above 10 V. When I connect to a oscilloscope I can´t see those peaks, but just the right voltage. My question is if this is a problem arising from the small voltage? Does my Card internally amplify the voltage? Do I need to amplify the signal before connecting to the card?
    Thanks for your answers!

    It should be quite easy for the DAQ-Card to read a 300mV signal at a sampling rate of 1kHz.
    I can't explain why you are seeing peaks of "2.5V and above 10V" - this sounds quite wrong - in fact most DAQ-Cards are not even capable of directly measuring anything greater then 10V.
    Most DAQ cards will measure using a default range of -5V to +5V (instrumentation amplifier gain of x1) unless you specify otherwise.
    In traditional DAQ programming, you specify your expected maximum signal range and LabVIEW/DAQ chooses a suitable board gain to cover at least your signal range. Board gain values are typically 0.5, 1.0, 0.5, 0.2, 0.1, 0.05, etc, etc, although not all boards have as full a range as some others do (it varies depending on cost/specification) - for example, the NI-PCI-6025E low cost board only has gain/ranges of 0.5 (+/-10.0 V), 1.0 (+/-5.0 V), 0.1 (+/- 500 mV) and 0.01 (+/- 50mV).
    So to answer your specific questions...
    i) No the problem you are seeing is not due to your lowish signal.
    ii) Your card can amplify the voltage prior to the DAC (digital to analogue converter) - although you need to program this as you deem appropriate.
    iii) Normally you don't need to amplify the signal yourself (except in special circumstances).
    Final advice - you should always try to use the default "differential" measuring mode in order to minimise noise - and check to make sure that your signal source is ground referenced to your PC/DAQ board by some route.

  • Low voltage radings? read this 1st

    I was concened about a problem with the rig in my sig, I had a low 12 v rail of 11.43
    so the brand new shiny 600w PS I just bought , or so I thought, was at fault, so I pop in my old trusty Antec 550 True control , same problem.  
    humm what is up? I bring home from work my good old trusty DVOM and check voltages on the molex connectors with the system powered up, now I get 12.35 and the 5V rail was 4.99
    so before you run out and get another PS best check it 1st , might save you some bucks!
    I emailed MSI about the issue , so we will see how that goes

    this issue goes for most motherboard out there.
    its partly because they use cheap parts.
    a cpy temp can easily be 20celcius off.
    also some programs shows wrong from time to time so always check in bios.
    and 11.4 is borderline.
    5% -+ on 3.3v 5v and 12v rails is within acceptable.

  • Low voltage FW on MBP 17"

    Does anyone have a trick for disabling the FW800 port on the MBP 17" in order to get higher, more stable voltage/ current on the FW 400 port?
    Digital camera backs will not run tethered unless they are connected to a powered FW repeater/ booster.
    Any suggestions?
    MBP 17"   Mac OS X (10.4.7)  

    hi - Welcome to Apple Discussions!
    if nothing is plugged into the FW800 port, that port does not draw any power.
    i.e. on MacBook Pros: Both of the FireWire connectors provide unregulated 12 V power, with a maximum combined load of 1.5 A. Developers should design to use 14 W sustained power, or less. One port may provide up to 14 W if no power is drawn from the other port, or both ports combined may provide up to a total of 14 W, such as 7 W from each port, simultaneously. (source)
    so, if the peripheral is not running stably using one port with the other unused, i would look to the tech specs on that peripheral... does this spec require more than 12V unreg and/or 14 W and/or 1.5A ?

  • Low voltage on kt3ultra2-non raid

    I have an kt3ultra 2 adn an xp 1700+ throughbredd ver b.
    The max voltage that i have in bios is 1.6 !!!!!!!!!!
    Haw can i have max 1.85 ???
    Thnaks...

    The defaults on these boards only allow +/- .1 volts on the Vcore so your only option to get 1.85 is by modding your processor, the socket with small wires, or the voltage regulator on the board to allow adjusting voltages above that.  The easiest way I have found to do it, and it will void the warranty on the CPU, is to use a defogger kit or conductive pen to close all the L11 bridges which will default the Vcore to 1.85.  You can adjust it back down in BIOS if the heat becomes a factor.  There is no beta BIOS or other version for this board that will allow you to adjust more than .1 either way as far as I know.  I have looked everywhere and never found one.  Good luck.
