3 or 4 Phase power?

does anyone know whether they use 3 or 4 phase power on the k8n neo?
usually they state it in reviews, but i can't seem to find it mentioned at all anywhere.
can anyone relay anything about this? ta.

You can try to clear CMOS and try out with another video card.

  • How much phases power supply does the 875P Neo FIS2R got ??

    How much phases power supply does the 875P Neo FIS2R got  ?(
    And will it be enough for the Prescott  ?(

    Prescott will be made on a 0.09u process so it should use less power per MHz, I wouldn't worry about that.
    According to what I see it has 6 power regulators which usually means 3 phase.

  • Three-Phase Power Analyzer, Etc.

    Hi All,
    I'm not sure if this is the right board for this question, or if I should ask it on one of the hardware boards.  Let me know if I should move it, please.
    I need to set up a LabVIEW-based system to monitor the following:
    1.  Output from three-phase power analyzer (480VAC, 0-100AAC) - this could involved monitoring formatted power-quality data from a power analyzer OR monitoring voltage and current on all phases, then doing the power quality calcs in LabVIEW
    2.  DC output current (0-200ADC) - This needs to be relatively fast (2000 samples/sec), but not very precise (0.1A resolution would be fine).
    3.  DC output voltage (0-600VDC) - Again, this needs to be fast but not very precise.  See current specs, above.
    4.  CAN bus - I'll be monitoring a CAN bus and processing CAN data, probably using an NI USB-8473.  I have much of the CAN code written already.
    Any suggestions on how I should proceed?  Has anyone had good results with specific power analyzers tied into an NI-based system?  What about current probes?  High voltage meters?  Is there any pre-written LabVIEW code for three-phase power analysis?
    Many thanks in advance.

    Hmm... I have used a few three phase power analyzers from Voltech, Valhalla, and Yokogawa with LabView.
    Right now I would say Yokogawa has my vote. Either the WT230 or (if you got the budget) a WT500. I am currently using both and find the Yokogawa supplied LabView vi's complete and full featured. Since neither of these can measure 100 amps directly you will need to use external current transformers. For best results I recommend buying matching current clamps from Yokogawa when you buy the analyzer Their use is pretty straight forward just enter the scaling factor into the instrument and the readings will be ranged correctly.
    DC current and voltage that high will require a current shunt and some scaling for your voltage. Then you could measure it with any decent DAQ device, maybe a cheap as a NI-USB6009. We like to use the Agilent 34970A with a 34901A multiplexer card for this application. The 34970A/34901A is our Engineering Lab workhouse it has the benefit of ISOLATED CHANNELS direct measurement of 300VAC/DC and it can read thermocouples.

  • P67A-GD55 board stuck in "CPU is in 1 phase power mode" loop.

    New build: mobo: as stated, CPU: i5-2500k, Cooler: Cooler Master TX3, PSU: OCZ700SXSP, RAM: 4x2GB PNY DDR3-1600, GPU: EVGA GT440, HDD: WD500AAKX, DVD: LGGH22NS50.  System assembled without a hitch in Cooler Master Centurion 534+ ATX case.
    Moment of truth:  Switch PSU on. System launched into loop of CPU 1 phase power mode = on for fraction of second, off for 1-2 sec.  The indicator is led 1 of 6 lighting briefly with each cycle.  The FP power led lights up and the fans all spin during the brief on periods. Started disconnecting peripherals and power connections, removing ram and at each test there was no change.  Got down to just PSU and mobo with still no change.  Pulled CPU power connector leaving just mobo 24 pin and still no change.  Reseated CPU and switched coolers somewhere in the middle of that. 
    What have I missed that will get this system to boot?

    Last update to this thread, just to say problem completely solved with the replacement mobo from MSI.  This one booted up the way it should and my new system is purring and running quite cool under all default settings.  Have just two 120 mm case fans, one intake and one exhaust, plus TX3 cooler on the i2500k.  MSI software says CPU is running about 29 degees and NZXT sentry 2 fan controller says bottom of heatsink is 23-24, with all temps min the case < 25 and no warm air exhaust.  Must be the relatively mousy GPU (EVGA GT440) not cooking everything in the neighborhood.
    I didn't build this for gaming, just for running a very large number of browser, Excel, Windows Explorer et al windows at the same time without hanging.  It's doing that now under W7 Pro 64bit.   to MSI for backing up their warranty and   from me when I use the new rig.

  • 3-Phase Power Monitoring

    Hello,
    I am planning to measure the Power consumption in a building which has a 3-Phase voltage system. Each line is 220V. I am interested in measuring real time kVA, monitor it with Labview through a data acqusition module. I will measure separately the Amps of each phase as well and i will calculate from that the Power Factor for more accurate power measurement. Do you have any suggestions on what voltage/current clamps should i use? These clamps should give reference voltages in the range that the usb NI modules vould monitor. Please also give me your opinion if the thinking of this project is right. Any other better solutions?
    Thank you,
    CK

    Have you thought about using the power meter PM870 from Square D (now is Schneider Electric)?

  • 2253iX California Power Supply USB Communication Issue FIXED

    I figure I would post this in the event someone else runs into the same issue.
    When trying to communicate to an 2253iX California three phase power supply through USB using labVIEW, it would always fail in the initalization block, when asking the unit for the model ( *IDN? ). The display on the instrument would display Error -113 "Undefined Header" Turns out the USB Com port driver doesn't work when registered as COM9 or greater. It has to be COM0 through COM8. Uninstalling a device in that range and reassigning the power supply's COM fixed the issue.

    not surprising... 
    I have been using California Instruments 5001iX AC source and 3091LD AC load for years and communications (RS-322, GPIB, USB)  have always been hit and miss when answering an *IDN? query.
    Even the newer series 2 models have these issues, but seemingly only with *IDN? query.
    I just put a loop in to query it several times before giving up.
    Also I have found Ci's set of IVI vi's are usless crap and have made my own using SCPI that work a lot better.
    What really makes me sad is Ci is still far superior than Elgar when it comes to AC power sources.

  • Power calculation using Rogowski coil

    Hello,
    I am trying to decide if I should build a VI, or if SignalExpress is capable of computing power based on my transducer selection.
    I am trying to calculate three-phase power of a system by using a 2-wattmeter method. I have a NI cDAQ 9178, Rogowski coil, and a NI-9215 module. 
    Since the output voltage of the Rogowski coil is 90 degrees out of phase from the actual waveform, I cannot simply multiply the voltage and current waveforms to obtain real power. I need to integrate the signal of the Rogowski coil and then multiply the two signals together.
    Is there an option on SignalExpress that allows me to integrate the signal or phase shift the Rogowski output voltage?
    Thank you.
    Solved!
    Go to Solution.

    Hi Jcesar,
    I think that the best way would be to integrate them in LabVIEW if you have that possibility, other wise a way to do it in SignalExpress could also be to add a LabVIEW step on your SignalExpress project, here you can find a guide that has something similar with a numeric integration.

  • Does the Master2-far have 2 phases or 3 Phases?

    Does the Master2-far have 2 Phases or 3 Phases(Power circuitry)? I ask this as I was reading that the Dual core Opteron cpus will require 3 phase circuitry, Is this true?

    Quote from: tcsenter on 11-April-05, 05:02:13
    "The memory interface -- all four slots -- are directly connected to the first CPU socket. The second CPU accesses the memory through the HyperTransport of the first CPU.  Theoretically eight slots (4 for each CPU like on the VIA K8W) would be possible but through the restrictions of the ATX form there is no room left for the additional four slots...The HyperTransport interface to the CPU runs at a speed of 800MHz up and down stream and provides a bandwidth of 3.2 GBit/s per direction."
    -- Valuation of the MSI™ K8T-Master2 from 3D Chips.net
    DDR333 = 2.7GB/sec (5.4GB/sec in dual channel mode) of bandwidth that the 2nd processor will be taking from the 1st processor's Hypertransport bus.
    But hey, its your money.  Use it as unwisely as you wish.
    Well in any case I will as It was My money and I didn't ask about the interface, I asked about the power requirements, Which You neatly side-stepped and ignored, So You're really , But then I run My cpus and ram at DDR446, Not DDR333. And this is with the one 512Mb Dimm in My Sig with Cas 2.0 timing @ 223MHz.

  • Power Analysis

    I am trying to develop a 3 phase power analyser to determine the output torque. I have found suitable voltage and current sensors and interfaced them to LabVIEW. The current waveform is sinusiodal but the voltage waveform is much more complex. Because the motor is driven by a switch mode variable speed drive, the voltage waveform across the motor is made up of many small pulses and is not sinusodal, it is atually a PWM(Pulse Width Modulated) square wave. I have perfomed a FFT frequency analysis and can see the fundumental and its harmonics, butb does anyone know how to proccess this waveform and determine the voltage accros the motor?

    Hi Danny,
    My expertise is in LabVIEW, and not 3-phase induction motors, but
    perhaps if you can give me some details on what type of processing
    you'd like to perform I can recommend a course of action in
    LabVIEW.  Specifically, what kind of processing are you looking to
    perform on the voltage signal?  You're looking for the voltage
    across the motor, but are you looking for an instantaneous value, a
    predictive model for the future voltage values, an average voltage over
    a time window, an RMS value at a given time, etc?  Can you refer
    me to the necessary equations to calculate the output torque of the
    motor?

  • P45-C51 - Noise from CPU Phase LEDs

    Hi,
    I've just finished setting up a new PC based on the MSI P45-C51 (MS7519) mainboard (see full specs for the system in my signature).
    Everything works fine, but.. The CPU Phase LEDs LED1, LED2, LED3 (the three blue LEDs in the upper right corner of the mainboard) emit some kind of very annoying high frequency noise as they flash (in sync with the hard drive activity LED on the front of the cabinet/tower).
    It's very important for me that I have a silent PC, so I've gone into great detail choosing the most low-noise components for this specific machine. Everything on this machine is very silent - except for the motherboard, which I would have expected would be the least of my problems when creating a low-noise PC!
    So my thoughts and questions are:
    - Is there any way I could turn off the flashing of CPU Phase LEDs (in BIOS, jumpers, software)?
    - Could it be a PSU issue (is 400W not enough for this setup)?
    - Or is it just a faulty mainboard (has other users experienced a similar noise from these LEDS)?
    I don't even see the reason for why the LEDs are there. The mainboard manual only has a very short and practically useless explanation of the LEDs. It only says what power modes they show (1 and 3 phase power mode) - not when and what to use them for..
    Hoping that someone can shed some light on this issue, and hopefully help me solve the problem..

    Now that I found out that the problem wasn't related to the LEDs on the MSI mainboard, I shifted my focus towards the CPU - The Intel Core 2 Duo E8400.
    From searching/reading about this specific processor on various pages found via a Google search, it sounds to me like a lot of other users have this issue to - it's called CPU whining - some kind of piezo vibrations caused by the extra power (that would normally be used by the CPU) which is being thrown back into capacitance when SpeedStep throttles down the CPU (no load). So it's not the CPU per-say, but the capacitors and voltage regulators that generates the noise (at least from what I am able to read). I guess it's not directly related to the MSI mainboard, and so maybe this post isn't even relevant in this forum any longer..
    When I write it's not directly related to the MSI mainboard, I mean that perhaps if I mounted this CPU in another mainboard, maybe the problem would go away - so I think it might be the combination of this specific motherboard and this CPU that creates this noise. A lot of other Intel Core 2 Users doesn't seem to have this problem, while others again complain about it. I guess it's also a very subjective question about how sensitive your ears are to high-frequency noises (probably in the 15.000-18.000 KHz range). Some write that they hear the sound, but don't care, while others hear it (and like me, are annoyed by it) from across the room through music, conversation and/or other background noises.
    Long story short, the users of the MSI HQ Forum (especially Jack t.N. - a lot og appreciation and thanks goes out to you, my friend  ) should not use more time and effort on this issue..
    Except if there's something that I might still have missed in the BIOS settings, that you think I need to try out first, or if this "newfound knowledge" raises any other questions or inspires a possible solution!
    I will leave the post open for a few days just in case.

  • New System - No POST, No Beep Codes

    Hey guys,
    So I built a new system last night, powered everything on and everything seemed to come on as expected but there was absolutely nothing on the screen.  The system MIGHT be posting properly because I see the keyboard lights flash when I first turn it on, then the Numlock light stays on as normal.  Also, when I press the numlock key it toggles the light as it should, and a ctrl-alt-del on the keyboard seems to reset the system as well (fan speeds change and lights blink just as they do when pressing the actual reset button on the case).  Additionally, when I had the drives connected it sounded like it was checking them looking for something to boot (even though the hard drive is blank right now).  However, I'm not sure that they're just making noise simply because they have power and are doing things like spinning down after not being used for a minute or two.
    There are no beeps or alerts coming from the motherboard that I can see/hear.  I also disconnected all the drives to see if that helped, but it was still the same thing.  I have not yet tried to take the mainboard out of the case and running it with only CPU/RAM/video; I plan to try that tonight as a next step.
    I'm guessing that this means there is something wrong with the video card, but I'm not 100% sure, and wanted to see if others had ideas before I try exchanging the video card.  Unfortunately I don't have another PCI-E system that I can simply test the video card in.
    This motherboard should beep if it detects a problem, correct?
    Are there any LEDs on the board that could help me diagnose something?  I don't think it came with a D-bracket.  There are the 4 CPU_Phase LEDs on the board, and I believe two of them are lit up while it's running, but I'm not sure how to interpret those LEDS.  Anyone know what exactly they indicate (more than what the manual says, which is just that 2, 3, or 4 lights indicates that the CPU is in 2-phase 3-phase, or 4-phase power modes).
    Am I correct in assuming that since the lights on the keyboard seem to behave as normal and that ctrl-alt-del works as normal that the motherboard is probably okay?
    Any other ideas or suggestions?
    Thanks!

    You can try to clear CMOS and try out with another video card.

  • MSI P67 GD65 2600 k cannot OC to 47x multi

    I tried everything with the voltages, it just won't post at 46x multi no matter what voltage all the way to 1.6V
    I can boot at 46x multi @ 1.3V but it needs 1.35V to be stable
    I'm on watercooling and the 1.6 BIOS.  I think it needs a bios update to do high multi properly.  Other people with otherboards had the same problem with not going up in multi but with a BIOS update they were able to get really high.  I'm at 32C on idle.
    I'm pretty annoyed because I got MSI because of it's SFC and Hi-c CAP instead of sticking with EVGA.  I found out it has only 6 phase power.  Some people with the same board were able to do 5.1ghz though.  I can't even do 47x multi.  I'm highly positive it's the BIOS.  Please respond saying you will update the BIOS of 1.7 to be able to do high multi.

    Stay calm young man, and slow down on emotional statements. The P67 chipset is brand new and all the manufacturers are trying to find solutions with Beta BIOS releases. Just read some other forums, and you will have similar problems throughout.
    Write down precise cause and symptoms and then report them to MSI technical. Every user's feedback helps to get to the solution. You cannot expect that someone here has all the answers. There are more questions currently than answers. Put your pen to paper in a rational and constructive manner and let MSI know exactly what you are experiencing.

    Nice runs there.  I'm right there too @ 4.8 with 1.4 makes 70C.  Having stability problems tho whenever I raise the BCLK.  Did you add some VTT to get to 103 ?

  • Vcore in 3.7mod BIOS Challenge for Aicjofs :)

    Aicjofs,
    I know that youve been asked before about the Vcore settings in the bios for the K8N neo4, but I thought Id bring up the subject again just in case there is new info.  Its my understanding that the bios is locked down for Vcore voltage based on the chip your running and I think it was 1.65 maximum no matter what.  Just wondering if you figured out how to unlock that setting so that no matter what CPU is there, you can run it up to 1.65 volts. 
    Im having the issue where I set the Vcore to the max of 1.4 volts for my CPU and overvolt of 9.9%  (Total set of 1.539 volts) but in CPUZ it shows as 1.488-1.5.  Now Im pretty sure this means my PSU is at its max even though theres no change in the other voltages,  probably going to have to get another  PSU........again :(     
    But I would still like to try to get into the Mid 1.5 volt range or higher for overclocking reasons.  Power need more power 
    Just wanted to ask or get others opinions.  (I really want to hit that 3 Ghz mark with my X2)

    Opps I just now saw this... 
    Here is the low down on what I know. 
    - Voltage regulator overvolt protection is ~1.7v
    - Voltage regulator is 3 phase, and not quite as high quality.
    - CPUz and the MSI board don't match up.  The only way to see for sure is but a multimeter on the board.
    - The Vcore is somewhat unstable compared to other boards. 
    - My board seems to undervolt, and it seems others have the same issue, why yet others don't.
    More each of these points again...
    - I don't see MSI giving us 1.7 for the obvious reason.  Another thought on that, if the overvolt is at ~1.7v then 1.6v is probably somewhere near the max stable for this design and it's longevity(Most systems set OVP at 5-10% above what the system is designed for under normal load).
    - 3 phase power and it's implementation on this board is probably the reason of the less stable Vcore compared to other boards with 4 phase or more.
    - Like I said the only way to know for sure is to hook up strait to the board.  In my particular case the voltage was closer to the lower CPUz value then Core Center/BIOS.
    - Seems the 3 phase problem again(not really a problem it's just the design).  Although if you have wild swings there is a problem.
    - The undervolting is bad because the general concensus for A64 90nms seem to be 1.6v max in the OC community.  Our boards only do 1.59v on the best day and if they undervolt you can't attempt to maximize your overclock.
    So now the BIOS thing.  It's there, the code is written into the BIOS, it's selectable.  The problem is somewhere before the menu code there is something that locks out these higher values based on what CPU is installed, or possibly what the max VID is.  Since ours are 1.3-1.4 then the options aren't available.
    I have talked with other BIOS modders that do MSI stuff, and 2 of them called it "super" locked.  Which really means if we were good enough could be unlocked but that requires more disassembly then is worth it.  There are guys that could do it easy, but getting their time, especially for an MSI board is limited.
    Like I said, it's there...
    But Wagon, what happens if you set 1.45 and 9.9%?  Should give you 1.595 in theory and probably about 1.53-1.55 in CPUz.
