UPDATED: Nvidia’s “deadly” flaw and how to fix it – no more squealing!

It is no secret that I am huge fan of Folding@Home project, or that I love to play computer games (when I find time :-(. Both of these activities put high amounts of strain on components inside the computer, and any weakness in product design can be easily discovered.

This tale speaks of a company that makes great chips, but also has a serious design flaw: PCB design. As long as story about “Built by Nvidia” components was told, there were isolated cases of “squealing”. This squealing is caused by vibration of copper coils, and is not present on products designed by people that take attention at these things. Read: if your card has Digital Voltage Regulation Module (DVRM, as Iwill originally called it – Digital PWM is more popular these days) or all solid-state caps and shielded chokes, no sound should be produced. But, if your part has coils or non-shielded capacitors/chokes, you could be “enjoying” in squealing sounds of electronics.

To make the matters clear, certain products from BOTH ATI and Nvidia can squeal under load. ATI moved to clear the issue, Nvidia didn’t. Unfortunately, I wasn’t able to record squealing with any of my microphones (upcoming test lab will feature ultra-sensitive microphone equipment), but in a silent computer with three Noctua fans, any non-standard behavior is noticeable. This high-pitched noise is often eaten by the sound of fans, but if you have a silent rig, it gets really, I mean REALLY – annoying.

The squealing is only appearing when the GPU is cranked all the way up, in Folding@Home, Far Cry 2, Crysis: Warhead – the same cards that squealed like pigs in Crysis didn’t do the same in Unreal Tournament 3, Fallout 3 or Race Driver: GRID.

After experiencing squealing with my reference Nvidia GTX280 card in the past month or so, I’ve thoroughly checked following products:

  • ATI Radeon X850XT
  • ATI Radeon X1800XT CrossFire Edition
  • ATI Radeon 2900XT 512MB
  • ATI FireGL V8600 1024MB (2900XT)
  • ATI Radeon 3850 256MB
  • ASUS EN9800GX2 1024MB TOP
  • ASUS EN9800GTX 512MB TOP
  • EVGA GeForce GTX260 Core 216 896MB x2
  • EVGA GeForce GTX280 SuperClocked 1024MB
  • EVGA GeForce GTX280 SSC 1024MB x2
  • Gainward GeForce 8800GTS 640MB
  • Gainward GeForce 8800GT 512MB
  • Palit Radeon 4850 512MB x2
  • Palit Radeon 4870 512MB x2
  • Palit GeForce 9800GX2 1024MB x2
  • Palit GeForce GTX280 1024MB
  • Sapphire Atomic 3870 512MB
  • XFX GeForce 8600GTS 256MB XXX Edition

“Squealing” appeared on several Nvidia and a single ATI board – and on EVGA 680i motherboard. On EVGA’s 780i and 790i FTW boards, where Nvidia design was replaced with EPoX engineering brilliance, no squealing appeared. I never noticed any squealing on following motherboards:

  • ASUS M3A78-T (AMD 790GX+SB750)
  • ASUS Maximus Formula (X38+ICH9R)
  • ASUS Maximus II Formula (P45+ICH10R)
  • ASUS P5E Deluxe (X48+ICH9R)
  • GigaByte MA-790GX-DQ6
  • MSI K9A2 Platinum (790FX+SB600)

Since squealing is coming as a consequence of a high-amp 12V rail, I decided to test the cards with several power supplies:

I also had that luck of testing the 9800GX2, GTX280 and ATI Radeon 2900, 3850 and 4850/4870 cards on two continents. First place where I did the test was Livermore, CA, using standard US 110V/60Hz current. Second location was Zagreb, Croatia, using standard Euro 220V/50Hz current.
This is the list of products that squealed in Crysis/Crysis: Warhead/Far Cry 2/Folding@Home:

  • ATI Radeon X850XT
  • ATI Radeon X1800XT CrossFire Edition
  • ATI Radeon 3850 256MB
  • ASUS EN9800GX2 1024MB TOP
  • EVGA GeForce GTX280 SuperClocked 1024MB
  • Gainward GeForce 8800GT 512MB
  • Nvidia GeForce GTX280 1024MB
  • Palit GeForce 9800GX2 1024MB
  • Palit GeForce GTX280 1024MB

As you can see, quite large number of cards produced some sort of noise, but with different variations. Most irritating were ASUS/Palit 9800GX2 and Nvidia’s GTX280, while other cards produced more subtle, but still high pitched noise. Power hogs like ATI Radeon 2900XT and new babies such as Palit Radeon 4850 and 4870 didn’t squealed. The reason is very simple: ATI pioneered the usage of digital power management (excellent design by Volterra) with 2900XT/V8600, went back to cost-effective analog capacitors/chokes on 3800, saw squealing re-appearing and again went digital with 4800 series. Result is very simple – no squealing under any circumstance.

Solution
If you own a card that squeals, you might ask yourself what to do. At present, only EVGA makes its own custom design cards with GeForce GTX 260 Core 216 and latest GTX 280 designs. All other partners are forced to use Nvidia’s reference design and well, squealing may or may not appear on your setup.

If you own a card that squeals, you should do following things:

  • Change the power cable. Incredible, but it did work on some cases reported by my friends.
  • Is your power clean or “dirty”? Putting a power-filter such as UPS might help.
  • If these two fail – mod the board.

Note that for instance, one Palit 9800GX2 squealed, two didn’t. After the mod, not a single one did. EVGA GTX280 Superclocked board (nV reference design) squealed, SSC ones (EVGA design) were good as gold. Gainward’s 8800GT continued to squeal after the mod.

We’re not talking here about “if you get Nvidia card, it will squeal”, but rather this issue is an isolated one, or “just how lucky you are”. However, this does not absolve board designers from full blame on this issue, since the “slaughtered pig squeal” issue could have been avoided by using digital circuitry.

Personally, I decided to go with warranty-voiding “coloring” of the board using color-less nail polish. For this experiment, we took Palit’s GTX280 and dismantled it. Daniela took each and every power component and soaked it with polish, and where she could, Daniela filled the inside of the capacitor/choke. We also removed all the factory-default thermal paste from the GPU and replace it with Gelid’s GX-1 compound. That reduced load temperature by 3 degrees, as we wanted to lower the thermal load of the PCB.

After putting the card back in the system, we turned Folding@Home back on and saw that squealing was almost gone and we only had a CPU and PSU fans on (OCZ Vendetta + Thermaltake Toughpower). It is not a 100% solution, but with all the fans back in the system, the board continued to fold and rock in games.

Conclusion
This issue is only the latest in history of recent scrutiny on Nvidia parts. Personally, I do not understand a dumb move done by circuitry designers who decided to continue using old, analog power management in time when Digital PWM is becoming more and more available. It is not true that Nvidia didn’t knew about the issue, since the first reports about squealing are traced back to nForce 680i and GeForce 8600GTS cards. Nvidia’s GTX200 series debuted at $449 and $649 price points and there is no explanation why more expensive digital circuitry could not be used. ATI introduced digital PWM with 2900XT, went back to analog with 3800 series, saw squealing re-appearing and went fully digital with the 4800 series. Case closed as far as Red Team is concerned. I spoke with several sources inside Nvidia’s and ATI’s partners, and they all moved forward to clear the squealing issue in their own custom designs, such as EVGA’s FTW series of motherboards of latest GTX200 cards.

We hope that GT206 and GT212-based cards will feature digital circuitry and that Nvidia will move in 21st century, as far as PCB design is concerned. Nvidia, here’s a free hint. If you need a contact in Volterra, I know a guy that knows a guy, we can make GT212 work all nicely, and SILENT!

P.S. I wish to thank Ivan and his girlfriend Daniela for all the help and dismantling their own GTX280 board. BTW Ivan, sorry to put it in public, but the digital camera on Sony Ericsson P1e sux. I wasn’t able to kill the noise even after 20min per picture in Photoshop. Grrr…

UPDATE February 1, 2009 00:40AM CET: I decided to update this article with a detailed picture of GeForce GTX280 and markings where nail polish or hot glue should be applied. Note that I haven’t tried the hot glue method myself. What needs to be isolated are the caps (marked with red line), but in case of Palit GeForce GTX280, squealing didn’t stop until Daniela put nail polish on the remaining power distribution elements as well (blue line).

Caps should be the ones producing squealing sound, but in case of our card, nail polish was needed elsewhere as well.

  1. haha, I never taught that my pictures will end up on the web, especially this public…

    And I must say that two of these pictures(the one with the coin, and one left of her) are taken with my SE k810i and they are just fine for the pictures taken with mobile phone ;)

  2. He he… well, you know – life with Canon EOS-400D (Digital Rebel XTi for honorable North American readers ;) and Nokia N93i can make you spoiled ;)

  3. Maybe I can help…

    I used a Sony ICD-SX78 set on highest quality, mic sens high and Low Cut Filter ON.

    BFG 8800GTS 512 OC (G92) – fan@25%
    Zotac 9800GTX – fan@35% (min in Riva T.)
    All other fans stopped except for PSU, Corsair VX450W which is pretty silent.
    You can my mouse click and a slight rumble in the background – my 2 hard drives. Otherwise, I tried holding my breath as much as I could… :D

    I made 3 tests, from 10, 50 and 100cm, by turning on folding clients for both video cards in the following order:
    both off -> 8800 ON -> both ON -> 9800 ON -> both OFF

    Here are the results:

    http://www.soundupload.com/audio/9ynj960qsssa7kgt
    http://www.soundupload.com/audio/fst8bpitt4uvum0n

    The Zotac 9800GTX has a higher pitch than BFG 8800GTS, but combined they are louder.

  4. Please make the following corrections in my previous post:
    - Corsair VX450W (0 instead of o)
    - You can hear my mouse (add hear)

    Thanks :)

  5. @Chipicao
    Yup, that is the exact same sound we were/are getting from our card…You really caught it well…it almost pierced my ears when I listened to it :P

  6. Oh, and Theo, Asus Maximus Formula has X38+ICH9R chipset and Asus Maximus II Formula has P45+ICH10R :) :P
    Just thought I should point that out :P

  7. WOW, I really didn’t think such a thing existed. When my 8800GT “squealed” in both Crysis and Far Cry 2, but ONLY those games, you have to wonder how to even approach a problem like that. I really thought I had just some isolated, weird fluke, or a gremlin or something inside my box. Thanks!

    My xfx gtx 260 black edition squeals a lot, in 2D, in 3D, any time.

    In 2D when i move a windows (in windows :D), this squeals…

    And when the GPU puts in 2D and slow down de Mhz (to 300MHz), dont squeals.

    A question:

    All nail polish arent conductors, dont?

  13. Good article..

    I just can stand that squealing and will get a AMD just to be on the safe side.

  17. Hi there, got a XFX 260 Black Edition. Mine is silent in 2D and in COD World At War, but it is insane loud in Crysis, Trackmania, and Stalker Clear Sky.

    I’m not sure if RMAing can help here, i mean this Thread makes me think every second GTX has that problem…

  18. RE: me3850 – Not sure what gfx card you use, by your nick I would say its the ATI Radeon 3850… I’ve only tested Nvidia cards with this type of fix, and it worked in my case.

    RE: Mick – the squealing appears when the GPU is loaded to heaven’s high… I had various experience with the cards, some squeal, some don’t. Sadly, it is more “luck of the draw” than anything else…

  19. Hi Guys,

    Firstly, great article, I’ve been interested in getting an evga gtx 280 for some time, after reading this article, i’m not sure if the one i intend to buy is one of EVGA’s new designs which wont squeel.

    Here it is:

    Can anyone tell if this is the new “squeel-less” design?

    Thanks in advance,
    Dave.

  29. This would be much more helpful if the pictures were higher quality and if the components that need to be painted were diagrammed.

  30. Correct.

    More and more people are getting aware of their squealing card and want to do something about it. Including me. The 200 series are a disaster. (asus engtx 285)

    Can’t find any information about the specifics of applying the nail polish. The technical data (why this should work) Some people are talking about a “hot glue” solution. Just need a little bit more info to take the step of trying this my self.

  32. Hot glue or nail polish will do the same thing. By filling the room between coils and the carrier you can stop the vibration that produces that horrible sound.

    What to do is very easy – fill in the holes. Hot glue or nail polish, does not matter, for as long as the material does not conduct electricity.

    This could have been resolved in the other way, by using higher-quality and better-designed PWM, such as going digital, but sadly, nvidia seriously dropped the ball on this one.

  33. Hey nice article, can u send me the pictures that Ironsole got sent please, because i just got a GTX 280 and it whines like a bugger.

    Any help will be appreciated. :)

  35. i dismantled my GTX280

    there is two components which upper half is moving. Its L16 and L17 on the front off board in upper right corner.

    Do i need to cover in polish them to ?

    I will cover in polish all C components.

  36. Hey Ironsoul tell us if it worked!!

    Im still unsure about this…

  37. i took off all white termo pads. Did i do wrong ? Did i do incorrect ?

    Will Arctic Silver 5 thermal paste do the thing ?

    I think that you removed thermal things from the GPU and replace it with Gelid’s GX-1 compound.

    but now i look in a picture and understand that white things have remained.

    what to do ?

  38. Heya guys,

    the story will be updated later tonight my time – thanks for your patience, but I was busy with the other project – we will also address the squealing situation on the upcoming site.

    RE: IronSoul – after you’re done insulating the caps, put the pads back on. Apply generous, but not too much paste on the GPU &(remember, whole GPU has to have a contact with the cooler), but DO NOT REMOVE pads from the memory.

    You cannot achieve same level of thickness with the paste, and you have danger of “yawning”, e.g. lack of contact between the cooler and memory/pwm chips. This could fry the card.

    You can try to remove the pads and put paste on, and then do a dry test – connect the cooler with the card, and then remove it – if there is solid amount of paste on the cooler, joint went well and you don’t need pads.

    If chips only left a scarce amount of paste on the cooler, then you do not have a good contact.

    Hope it helps ;)

  39. ah there go my 200+ $ video card :( Now i need to wait when Accelero Xtreme GTX280 will come to shops in my forgotten country. Because in here i can not buy 3M™ Hyper-Soft Thermal Pad No. 5503S or http://www.rapidonline.com/productinfo.aspx?tier1=electronic+components&tier2=semiconductor+hardware&tier3=thermal+pads&tier4=t-flex+200+gap+filler&moduleno=68127 or other thermal pads :(

  41. My GTX260 only squeales during high-framerate situations. For example in the menus of some games where fraps shows around 1000 or 2000 fps. I’ve squealing also during a 3DMark 2001 Benchmark test – there I’ve also a very high framrate.
    During “normal” gaming (e. g. Crysis) I can’t hear anything istead the fans.
    If the GPU is “cranked all the way up” I don’t have any squealing but in high fps situations I have.

  42. EDIT By Blog owner – A person posted an offending comment and didn’t gave out his e-mail details for private verification, yet offered a good explanation why this case is happening across the Nvidia’s line-up.
    Information given should be considered valid, but probably coming from a person who is a member of the team that should be blamed for this design choice

    - PWM power supply controllers have been present in high to low voltage conversion power supplies for almost a decade now. There simply is no other way to convert power efficiently for the required load (GPU current). The statement that NVIDIA isn’t using PWM power supply controllers is 100% wrong, and actually the controller has nothing to do with the high pitched squealing noise heard.
    - In fact, what amplifies the writer’s lack of understanding of what a PWM power supply is the fact that he cant recognize the same power supply controller on the GTX280 that exists on the high-end AMD cards. See the black square on the top side of the card, on its bottom right corner (right under the red “1” in your picture)? Notice it has a V on it? Could it be “V” for Volterra? Looks like NVIDIA has some Volterra contacts of their own already … maybe they just don’t know the author’s guy?
    - Even worse, the author doesn’t understand what the difference is between digital and analog controllers. It has nothing to do with the existence of PWM control, and all to do with the level at which the control parameters are configured (SW registers or HW components). In fact, Volterra is known to NOT be a fully digital controller, but rather a hybrid. Other controller companies, such as Primarion, which have been featured on products like 8800GT and 9800GTX, actually design fully digital PWM buck converters – but none of that is relevant to this issue.
    - The squealing isn’t necessarily caused by the vibration of high frequency coils, mostly because coils don’t exist in most of today’s high end inductors – there is just one strip of metal. In fact, that squealing could theoretically be caused by any component on the board, though inductors and capacitors are the biggest culprits.
    - The statement about “solid-state” capacitors isn’t clear what you are referring to, that term doesnt exist for caps, however actually a large variety of caps (from MLCC’s (small brown squares) to ALE’s (cans)) have shown an aptitude for creating noise, some better, some worse.
    - The 12V rail isn’t a high current rail. Everything in life is relative of course, but on a DC-DC buck converter power supply, it is the output (the ~1V on the GPU) of the power supply that carries all the large currents, the input has a current roughly 10x smaller for this application.
    - Changing a power connector to make the problem go away isn’t an indicator of “bad supply power”, but rather that the noise is coming from the PSU of the computer, and not the graphics card. I guess that poor circuit design isn’t limited to NVIDIA engineers ;-).
    - Inductors have air gaps in their casing that allows for heat to escape (as well as from their leads). Covering your parts with nail polish could help the sound go away, it could also help shorten the life of your board dramatically.

    I wish I could tell you more about actual root cause of the problem, but as you can probably guess, I will be putting myself at risk at that point. None the less, clearing the record on the many false statements made in this article was something that needed to be done.

  51. Are you sure squealing is non-existant for 4800-series ATI cards?

    I know my card squeals when running Folding@home full load. It is that only some cards use digital PWM?

  52. Blimey, I thought I was the only person in the world to experience this!

    I don’t get it anymore with my current setup (790i ultra board, x2 8800 GTXs SLI) but in the past I used to get a terrible squeal from my X800 XT PE whilst playing Guild Wars (probably the most graphically intensive title I had at the time) but nothing else…it was absoutely bizaar and didn’t know how to even start approaching it.

    Not that it will help me today but I have still got that rig at my father-in-law’s house…I might go into it with some nail polish and see I can stop the squeling for research purposes!

    Does it make any difference what colour the nail polish is? :P

  53. I have found another cause and solution. Apparently the PSU may not be the only factor but nearby expansion cards as well.

    My Gigabyte GTX-295 was squealing horribly anytime I started a game like GTA 4 even with VSync on. I discovered that the problem was being aggrevated by an Adaptec 5405 SAS controller in the PCI-E slot next to it. I had moved the Adaptec to another slot farther away to keep the heat it generates away from the GTX-295. When I started up GTA 4 again the squealing was gone completely and stayed gone even after several hours of running the game. I have an Auzentech Forte 7.1 next the GTX-295 with no problems.

  58. I purchased a new videocard. Nvidia GTX 285.
    It’s annoying,even when i watch some videoclips in Youtube ,when i connect Yahoo Messenger,and other different web sites.
    I would try like Daniela did ,but i’m affraid,maybe i damage the card.
    When i start a game,the noise is only during the loading,after that,whan i’m playing,there is no more “noise coil” at all.
    Would you recommend me to RMA the videocard,or trying to apply nail polish ?

  59. Always the same rule – RMA first. Claim weird annoying noises coming from the card… and you can freely link to us and state that you do not want to void the warranty, but that the sound is very irritating…

    • I agree with Theo. RMA the boards with squealing. Show NVIDIA and card manufactorers that this kind of cheap design is not accepted by their customers. I’m glad I recommended an ATI card to a friend who just built a new PC. A Sapphire Radeon HD 4870X2.

  60. You don’t want to open a power supply its like opening a TV you’ll get the worst zap of your life, the capacitors carry way to much electricity even if you haven’t used/plugged your power supply/TV to the ac outlet after 20 yrs.

    RMA your power supply it will prob die on your ass

  63. [...] Cred ca e coil-noise. Nu prea ai ce sa-i faci si nu e acoperit de garantie. If you own a card that squeals, you should do following things: Change the power cable. Incredible, but it did work on some cases reported by my friends. Is your power clean or “dirty”? Putting a power-filter such as UPS might help. If these two fail – mod the board.

  64. I covered the caps and their bases with clear nail polish and the squealing is completely gone. I started up ATITool’s 3D view which normally gives me the loudest sqeals and the sound was replaced by a quiet hum. Thanks a lot for this advice!

  65. Hi,

    hopefully I am not too late to ask this but, what can go wrong if you do this? Can I ruin my gfx card? It’s only 2 weeks old, but it squeels so loud, I’m going to lose my nerves with it…the case is an opened one and it’s right next to my head, which doesn’t make things any better.

    It’s a GTX 275 by BFG, btw.

    Hvala za odgovor! ;)

  66. I have just done this modification using nail polish.
    -My card still works
    -Coils are silent now in normal gameplay
    -Still a (much more faint) squealing when at very high fps

    Thanks a lot for the tip ;)

  79. This article looks interesting, probably a solution for my squeling hd5770, but i have a question :

    The pictures are unfortunately have a very low details and the writing is not as clean to me…probably you can to tell me EXACTLY what parts must to “paint” with the nail polish on the capacitors ?

    All over, only @ the top, or under the capacitor (inbetween the board and the capacitor) or everywhere where i can ??

    I really don’t wanna to harm the gfx card. Please make it clear. Thanks.

  85. Igarashi said: “For a long time, I feel very embarrassed men nail, but in the end I was afraid to come here to nail

  86. I feel your annoyance. I never had any luck with
    this kind of thing, either. So happy to find out I’m not by myself!

  87. Have you ever considered about including a little bit more than just your articles?
    I mean, what you say is valuable and all. But think about
    if you added some great pictures or videos to give your posts more,
    “pop”! Your content is excellent but with images and video clips, this website could definitely be one of the very best in its niche.

    Great blog!
