MSI z87 X-POWER 100% GPU load at idle

guys,
i have just bought the z87 x-power. System specs are:
-i7 4770k
-2 x Asus 6950 1 gb in crossfire
-16 GB GEIL ram
-Samsung 840 series ssd
I have flashed the latest 1.3 bios.
My problem is that even when my system is idling, the GPU in PCIE slot 1 (the uppermost slot) runs at 100% load. If i enable crossfire, both cards run at 100%. It draws A LOT of power. The temporary fix i have found for this is to disable crossfire in CCC and enable it again. Once i do this, both cards work fine and the power consumption and gpu temps return to normal levels. But i have to do this every time i start my PC.
I have tried the following to no avail:
-swapping the cards around (the second card is in slot 5 as per the boards instructions for running two cards).
-removing the crossfire bridge
-swapping the power connectors
-uninstalling and re-installing the drivers (i'm using the latest 13.11 beta drivers).
-using driver sweeper to completely remove all GPU driver data.
-restoring optimized default settings in bios
-swearing.
-praying to allah, baby jesus, mick jagger.
The problem persists even with no drivers installed (using gpu-z to check the load and temps). This leads me to think its not the AMD drivers causing the issue.
has anyone else encountered this issue? it's doing my head in!

I googled your problem and alot of people seem to be having the same problems because of a bitcoinmining malware.
Check Processes when your gpu's are @ 100% to see if u can find : iehighutil.exe
Just a thought.
thanks Mojo. have had a pretty thorough look and i dont have that process. Do you know if that malware uses any other names? I noticed that atiedxx.exe was using a fiar amount of system resources and it disappeared when i disabled and re-enabled crossfire. a search on atiedxx.exe doesnt return much in terms of malware.

  • Msi z87 g45 power cycling

    I recently built a new pc in November and haven't had a problem with it until now. It doesn't post doesn't beep and won't boot as well. No display and it does this very thing with nothing plugged in at all (obviously the psu is plugged in).
    My specs:
    Msi z87 g45 gaming
    I5-4670k (not over clocked yet)
    Gtx 660
    Corsair vengeance  2x4 gb ram
    60 gb  Kingston SSD
    Evga supernova nex750b psu
    The problem started yesterday when I had removed all of my components to route my psu cables.
    After getting everything installed correctly I plugged it in and hit the power button and it came on for a second and turned back off I thought I had forgotten to plug the 8 pin cpu power in until it turned on a second later and immediately turn off. I quickly killed the power and had a look inside but nothing appeared to be wrong.
    Now every time I turn it on it sits there turning on and off until I unplug it.
    I've tried switching the ram the psu and reseating the cpu several times and nothing works.
    I did manage to get it to stay on by shorting a jumper labeled "J1" but  there's no display or anything other then the fans and LEDs being on.
    Anyone know what could cause this? Everything is brand new  and  has only been running for a month and was running two days ago.

    I have tried clearing CMOS by the button the battery and the jumper.
    The only bios setting that I changed was to set my ram to run at 1600mhz which is what it's rated for (it was running at 1333 on the auto setting)
    The thing that puzzles me is that J1 jumper that is right next to dim 1.
    If I hold a screwdriver to it during the power cycling thing it stays on as long as it's being shorted but I don't get a display or anything everything is on and spinning but it doesn't boot. As soon as I take it off it reverts back to the cycle of on and off.
    I've searched google for any possible incompatibilities or fixes but I couldn't find any.
    Also something I forgot, I accidentally bent one of my usb 3.0 pins to the point where it touched another pin. Could this have caused my problem? If so rma wouldn't work cause I bent a pin. I'm totally fine with buying a new board but I'm not sure if it's the board or some other component.

    RMA the VGA as Henry said
    Small Update:
    two things: 
    First:
    I noticed that the gpuz, report it when VGA is under load ( furmark )  the voltage  VDDC value the higher value is 0.96, is a low voltage ? 460gtx under load  must be near 1.02 ?
    Second:
    My reseller told me that behind the card must have an sticker "void warranty if removed " over OCP protection but the card does not comes with that sticker is that possible ?
    Thanks in advance

  • CS4 100% gpu load on second gpu

    In CS4 64, my second gpu goes to 100% load in photoshop. It happens with opengl drawing and also with opengl drawing off after I open up a simple image like a flat bmp. If I close the bmp it's still 100% on that second gpu. It turns up the fans and costs power.
    I'm on windows 8.1, have two hd7950's in crossfire with rather recent 14.7 whql drivers.
    I was wondering if anyone knows a solution.

    Photoshop has a problem if you had two different GPU in you machine. Are both the hd7950 the exact same ?? If so report to Photoshop Family Customer Community
    I have also see hits on  hd 7950 crossfire compatibility searches on the web
    Photoshop CC and CC 2014 GPU FAQ
    Are you using more than one video card?
    Multiple video adapters can cause problems with GPU-accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model.
    Otherwise, crashes and other problems can occur in Photoshop.
    Note: Using more than one video adapter does not enhance Photoshop's performance.

  • Is My MSI Z87 MPower MAX Safe?

    Hi everyone!
    May I ask is my MSI Z87 MPower Max safe?
    Intel 4770K - Idle = 45 Degrees Celceius / Open For Long Time = 53 Degrees Celceius
    MSI Z87 MPower Max = 42 Degree Celceius
    Core 0 - 3 and Package - Idle = 40 Degress Celceius / Open For Long Time = 48 Degrees Celceius
    May I know is that safe and normal? because I got the Noctua NH-D14 heatsink fan.
    Thank you!

    its safe!
    for 4GHz CPU frequancy that temp is all good if it tops out below 75C when its under maximum load when you get around to testing it then its all good and you have nothing to worry about!
    so try intel burn test till it hits maximum temp it runs at and see how hot it gets (remember any temp under 100C is safe but the lower the temp is under that the better!)
    so get the cpu a maximum sustained load to see how high its  temps go to and report back to us but it looks fine so far and maximum temp is the most important metric to have (idle and light load temps say very little as they sound totally fine so far)

  • N660 TF 2GD5 - PerfCap/GPU load/Power consumption problem

    Hello,
    at first, sorry for my english, I will try to do my best.
    I have problem with my GPU when I play Battlefield 4. Problem occours with newest Nvidia drivers, also with beta and older drivers.
    Problem is that I have huge FPS drops periodically, coming maybe every 5 minutes for 15-20 seconds, for example in BF4 it means FPS drops from 50fps to 15fps, really annoying.
    It does not matter at scene complexity, it´s the same in huge battles as when I am alone looking up to the sky.
    I was searching why is this happening and GPU-Z helped me to indentify PrefCap, and immediately GPU load + Power consumption going down from 100% to 40-50%
    I have a screenshot, but can´t findout how connect attachment (external links are not allowed).
    Could somebody explain me what is the problem and why is this happening? I am thinking about to sell my MSI graphics card and buy another one because of this, I don´t want any throtling problems because of compatibility or whatever   
    Is there any way how to turn it off or disable? Register, something.
    Thank you

    you seems to be right guys.
    I undervoltaged my CPU by -0.1V, lovered Frequency to 3600MHz and problem is gone.

  • MSI Z87-G45 will not load OS with two SATA HDD's connected

    I have an MSI Z87-G45 board and I am attempting to connect a second SATA HDD. Each time I connect the second disk and then power up the workstation I get the following message:
    Reboot and Select proper Boot device
    or Insert Boot Media in selected Boot device and press a key
    The primary HDD is a WD 160GB drive and the secondary drive that I am attempting to connect is a WD 2TB drive. I am not trying to dual boot, I just need a second disk for a little more space available. I am not sure if there are some settings that would need to be changed in the BIOS, but I would think that by default I could connect a secondary HDD, and it would be recognized as such. Anyone else dealt with this or have any pointers? This is really driving me crazy.
    I should note everything else with the workstation works perfectly, it's just when adding a second drive, it will no longer load windows 7 from the 160GB drive.

    That is one reason this is driving me crazy, I have made sure that the 160GB drive is primary in the boot process. Is there anything else you can think of that may be causing this?

  • MSI Z87-G65 adding PCIe cards, how will the GPU PCIe remain?

    Hi,
    I'm about to to buy a MSI Z87-G65, but currently having issues with Realtek 1150, while its really much better than past sound cards, i have issues with drivers, since MSI also run the same sound card, i want to run a HT | OMEGA eClaro 7.1 Channels 24-bit 192KHz PCI Express x1 Interface Sound Card and im also not too keen of the choice of MSI on the network card, i had issues on my GT70 on my lan and wifi, that has been worked out but i hate the Killer software/panel, this PC will also transfer a lot on gigabit so don't want to deal with poor performance, so im planning on a good trusty Intel EXPI9301CT Desktop Adapter Gigabit CT 10/ 100/ 1000Mbps PCI-Express 1 x RJ45.
    I know when you run SLI on PCIe 16x, the first goes to 8x and the second to 8x, when 3sli is ran it goes 8x4x4, but im using the layout like the following, wondering what speed will the first 16x PCIe slot will run with the configuration below, 16x or 8x or 4x?

    You can't run nVidia graphics at 8x 4X 4X. Tri-SLI is not possible. Crossfire is though. Download the pdf English manual at an MSI Website. It gives all the information of the lane assignments.
    To answer the question, if other PCI-E 16X33 slots are used other than the primary for graphics, the primary will indeed drop to 8X.

    I don't really know if your non-identical cards working fine when  combined crossfire.I think two identical card  either for crossfire or sli are the best solution to avoid troubles. Apart from that ,you have enabled your crossfire setting from your driver ,right?(and your driver is up to date,I suppose)
    Edit:
    P.S though Having a dual gpu card combined with a single gpu one with crossfire...I think that's impossible.

  • MSI Z87 Mpower fancontrol and disabling the iGPU

    I have two questions about the Z87 Mpower mainboard:
    First of all it seems that I can't control my CPU fans (2 Corsair SP120's, 3pin). Moving the sliders around doesn't change anything and they keep running at full speed. Is there any way I can check the voltages that the fans currently run on?
    Secondly I want to disable the integrated GPU but I can't find any settings in the BIOS that allows me to do that. Am I not looking hard enough or is this (quite basic) setting just missing?
    Interesting specs:
    MSI Z87 Mpower (basic version) with the latest BIOS (for now)
    Intel i5 4670k @4.5GHz @1.3V
    Corsair SP120 high performance edition (3pin version)

    Im not sure if this is the case with your setup, but on most motherboard the CPU_FAN headers are PWM controlled, not 3pin, this means that even though you are changing and the motherboard is trying by sending the pwm signal your fans are not recieving it as they are 3pin, in some motherboards the manufacturers does offer the ability to change the CPU_FAN header from PWM to voltage control (asus if im not mistaken does with Q-Fan from auto to manual), and this would be the only way to control you Corsair 3pin fans from bios on the CPU_FAN header.   
    MSI is amazing on bios though, im about to switch from ASUS to MSI out of their really good implementation of PWM control on pure bios, but all my fans are PWM and im going to use some splitters that will draw power from a psu molex and control them all with the PWM signal of the CPU_FAN header, at least thats the plan.   Asus is very restrictive on their bios on PWM control, 40% is what their new ROG series have, while MSI allows 12.5%, 25%, 37.5%, much lower than what asus offers.  But on pure software, MSI is behind, its impressive what Asus has done with FANXPERT2, ability to by pass bios restrictions and fully control fans from 0-100% with mulitple points of tweaking... its very nice.
    But back on the subject, check if you motheboard allows or has an option to change form PWM to Voltage control on the CPU_FAN header, else you will need PWM fans to control them via that header.

  • Which MSI Z87

    I'm in the process of moving back to ATX in haswell, I dont overclock as much as used to, looking for mild oc around 4.2ghz, i prefer a cooler and more quiet build.  I did a Z77GA43 build for a friend, and i really liked the way the BIOS manages PWM fans. 
    I dont really care much about 8/12/16 power design, but i do care about fast booting, the z77GA43 was by far the fastest loading PC i have ever built, hoping the MSI Z87 does follow that trend, if any of the mobo boots faster please let me know
    Another thing that i do value is clean sound, in the past i had issues with mouse movement creating static sounds, this is something that i would like to avoid if possible, dont need to be ubber just not ruin it with noise.
    Another thing that im looking for is two slots separation between 16x PCIe slots, i do plan to move into SLI setup in the near future as soon as i can afford a 4k monitor, probably will be next year.  Also that the first PCIe slot isnt the 16x, as ill be using a big cooler like Thermalright Silver Arrow SBE and will pass over it.
    Stability is the most important thing, not only OCed, but stock, drivers and support has to be there.  One other thing that i do value is the nic.... not a huge fan of killers/qualcom, but on my MSI GT70 with the newest drivers seems steady enough, and while i would prefer intel, i think i can live with the killer 2205.
    Fan control on bios is extremely important, hopping i have the same presets as the Z77GA43, 0%,12.5%, 25% this are the three that im interested.
    This is the planned build
    CPU: i7 4770k
    CPU Cooler: Thermalright silver arrow SBE
    Memory: Crucial Ballistic Sport Ultra low profile 4x8GB  DDR1600
    CASE: Fractal Design Arc Midi or Define R4
    CASE FANS: 6x Noctua NF-A14 PWM
    PSU: Seasonic X660 (will be upgrading when i move to sli, but for now its fine).
    SSD: Samsung 840pro 512gb
    HDD: Hitachi 7k1000 1TB
    GPU: Galaxy GTX780 + Accelero Extreme III (i wish i would have gone with N780 but i couldn't wait).
    So the motherboards that im considering are, my budget is $220 at the most,
    MSI Z87-G45 GAMING - Cheapest but no seperation on teh PCB for the audio.
    MSI Z87-GD65 GAMING - Idk if its worth the extra $$$, features like extra bios is nice but only once in 7 years i have used it once, nice to have when you are in trouble, the extra power design might be better, but i wont oc that hard for it to make a difference.
    MSI Z87 MPOWER - More expensive but this one seems to have the board sperated PCB for the audio, and imo looks nice with the yellow glow.... the audio seems different in design on the CAPS, not sure if its better.
    So help me decide, atm im thinking on going with G45 as its really nice and cheap, but if you think the Mpower will have better audio and less prone for noise on the sound card, ill do the effort.

    i agree GD65 is the best balance and should be good enougth for what you plan to use! any of the higher ones would be overkill and a waste of money really!

  • MSI Z87 G45 GAMING erratic BSOD/freeze @ 2300, stable @1600. Can't solve.

    Hi All,
    I would welcome some advice. I am about 4 months into a new machine build:
    * MSI Z87 G45 GAMING motherboard
    * i7-4770K Haswell 3.5 GHz & aftermarket heatpipe cooler
    * 4 x 4Gb G.Skill SNIPER DDR3-2133 PC3-1700  (F3-17000CL11D-8GBSR)
    * GeForce GTX 650 Ti  w/ 2 Gb Video RAM
    * Samsung 840 Pro 256 Gb SSD
    * Thermaltake 700W Toughpower
    * Win 7 Pro 64-bit SP1
    The system seems to run fine at the default 1600 MHz RAM speed, however if I implement either of the X.M.P. profiles (which kick the memory speed up to the RAM's advertised  speed of 2133 MHz), the system will occasionally (every 8 to 48 hours) freeze or BSOD.  The BSOD stop codes are inconsistent in number (0x00, 0x41, 0x1E, 0xC4) and driver.  When the system freezes, there is no consistent behavior.  I am not doing any other overclocking besides using the X.M.P. profile in the memory. 
    RAM timing on the 2133 X.M.P. profile is: 11-11-11-30.
    I have updated the BIOS to 1.5, including the ME, and updated all drivers in the system.  All irrelevant hardware and drivers are disabled.  Also I have done the following:
    * MemTest+  5.01 for over 30 hours, all 4 sticks in.  No errors.
    * Intel BurnTest on 'Very High', 10 passes, no errors
    * Prime95 for over day with 90 C CPU temps constantly being hit.  No errors.
    * Unigine Valley Benchmark for 30 minutes; no issues
    I increased V_DRAM from 1.60V (from the XMP profile) to 1.65V, and I also added  +0.10V offset to increase the CPU I/O ANALOG , CPU I/O DIGITAL  and SYSTEM AGENT voltages.  Didn't seem to help.  All other CPU voltages are default from [auto].
    I rolled the memory speed back to the default 1600 MHz, and the system seems stable as a rock.
    I don't really need to have the memory run at 2133 MHz, but it irks me that the system is not stable with the rated components, and I'm befuddled why the stress tests seem to pass just fine, then the system will randomly hang with arguably a far less demanding load than the stress tests.
    Note that I have not yet:
    * reset the CMOS when changing to X.M.P.  Perhaps I should?
    * reseated the graphics card or CPU.  The latter will require R/R of the thermal grease, which I will do if needed, but it's a pain.  Since the system is stable at 1600 MHz, I assumed that all basic systems are working as they should.
    * Tried to work my way up in memory speed step by stem from 1600 to 2133 to see where things fall apart.
    * Tested the video memory
    I suspect main system memory, despite the clean bill of health from MemTest, and based on many of the comments to others with similar problems from the veterans on this board.   I don't want to push the CPU voltages too much above the default/auto values, for fear of damage and reduced lifetime.
    Also, the power supply is a nice unit from an older high-end gaming rig. It is rated at 700W.  The PS does probably have over 30,000 hours on it (24/7 use for 3-4 years), however.  Strange that it would work at 1600 MHz fine, and with only slightly more power load at 2133.  I suppose stranger things have happened. 
    I've read the suggestions to run only 2 sticks, rather than 4, but I can't justify dropping $140 on new memory (I don't really need the extra speed benefit, it's more curiosity and just not knowing at this point).
    Anyway, perhaps more seasoned souls than I can share their thoughts.  The system is perfectly usable at 1600, but I'd really like to know where the lockups are stemming from.  Troubleshooting is maddening because of the inconsistency in the long times before failure and lack of repeatability to reproduce the issue.
    Thanks in advance for your time.

    Thank you both for the prompt replies.  I'm learning a lot.
    Turns out I also found this from G.SKILL in going over reviews of the memory modules I have.  Another user had a similar configuration as mine and was having similar problems.  G.SKILL replied:

    We are sorry to hear you were unable to get two kits working in the same system. It is not guaranteed two kits can operate at the rated specifications since they were not pre-matched, tested, and guaranteed at factory. With multi-channel motherboards, perfectly matching memory is necessary to achieve high frequency. This is why we must offer high capacity 32GB, 64GB kits, otherwise we can just sell one module at a time and have you purchase as many as you need. Unfortunately, memory does not work that way. If you purchase a 16GB kit rated at DDR3-2133, you should have absolutely no issues. For any further questions or concerns, please feel free to contact us directly for assistance.
    Thank you

    Not knowing any better, I simply purchased two "kits" of 2x4 GB each and installed them.  Perhaps worse, if the modules were matched, I may well have mixed them up so the matched modules don't even sit in the same channels 1/3 or 2/4.  G.SKILL seems to have a pretty responsive board, so I'll ask them what they suggest.
    Also in the end, I really just want a stable machine. This is a basically an office/engineering machine.  My initial thinking was that if the system was unstable at 2133 then there is something wrong with it that needs to be fixed.  It sounds instead like getting to 2133 is not guaranteed, and is much more of an art than simply throwing the modules in and powering up the system.
    I'm perfectly happy at 1600 knowing the system is stable.  Indeed realizing now that 2133 requires overclocking, I may well have backed off to 1600 even if everything had worked just fine at 2300, just to trade extra stability for the (small) performance improvement that I would likely never notice anyway.
    I'll put together a post for the G.SKILL forums, and if I get anything useful I'll post what I learn here for completeness. 
    Thanks again for the fast and informative replies.  It's much appreciated.
    Best,
