I think that was for me :DQuote:

However, these issues about underclocking, RMA if you can etc. are described quite detailed in the original post ;)
I am sure that it is not required to change all the capacitors !!!Quote:

I have been thinking A LOT what kind of capacitors would be good enough for
that purpose and I am not still sure.. There are much more 'moving parts' in that circuit, that I thought at the starting point. At least following aspect are critical:
- Very low ESR ( value of < 0.05 ohm, I do not know exact value yet)
- Very high ripple current (value > 1 A , I do not know exact value yet)
- Capacitance value 470 uF (or higher BUT very high value causes other problems..)
I am working all the time to make good specs, but it is not easy beacause I found
very stange aspects that have to be re-checked (I will post this info soon...)

Before make that modification please post following details:
- What is your card model/version
- What labels there are at top of those "c136 and c143" caps e.g. "4 8 470 6E"
- What kind of Sanyo capacitors you are going to use (the one I mentioned ??), AND how you can obtain those in small volumes ( I have not yet found a place :p: ) !
Ah ha :D Ok.Quote:

There's also some 'Sanyo OSCON' caps on there, 220uF / 10v .. the specs are:
3370mA
27Ohm @ 300kHz
Any good?
You mean these ?Quote:

.. I think no good for replacement for the originals, because they are leaded (bulky) components (=hard to place etc.). I wonder those should be ~ same size, SMD-components like shown in here:
http://www.semicom.co.uk/manufacture...ducts_svp.html
Yeah those, well, the first link isn't the exact ones I found but very similar.
Are you going to go all the way and actually replace the [believed to be] faulty caps now?
No at least now.. I have to solve some/many aspects before I will modify anything (e.g. capacitor specifications !), and therefore a unmodified card is required.Quote:

thanks! i feel better. im scared the returns dept at this company will start to accuse me of time wasting and say it must be my system.... :mad:
the dual fan gainward didnt BS, but it only lasted an hour in my system because i couldnt hear myself think
It is wierd that they (=that company) have not heard about BS-feature, because so many are complaining !!Quote:

Sika, the audio test... I think you may find it interesting to know that I seem to have this problem, I think.
I don't have a cd audio cable, the noise doesn't come through my speakers. It comes from the actual card? There's no weird noises (high pitched squealy noises) when the card is idle, as far as I can hear, but when I start something 3D some funny high pitch noises seem to come from the card.
Is this the same thing you're talking about? I always assumed this was normal. My other Leadtek 6800 also makes these noises... but I don't know if that one black screens. Haven't had time to test. It has '44 470 6E' caps.
EDIT: By the way, your sound links dont work :(

Anyway, you test proves that this is a common feature of BS-cards and maybe also feature of BS-cards-in-future !!!!!

I know those **** -links.. it is angelfire again ! I managed to download them by copying the link and paste it a new window - not so nice but working !
Copy pasting the link in a new window ( tab actually ;) ) worked.
Those noises seem really bad on yours, oerhaps not the same thing I am experiencing? The noise actually comes out of your speakers aswell? Mine makes noises, but not as bad as what I heard from your recording ;)
Please, note that I amplified those signals VERY MUCH and only the frequency variation is relevant. These noise signals have been recorder by connecting mic-input directly to audio-out.Quote:

I think I have an audio cable laying about somewhere. I'm not entirely sure if my motherboard onboard sound/soundcard ( not your regular Audigy2, Audiotrak Prodigy here :P ) even has the pins for the cable though. I don't remember seeing them before...
I'll have a look and get back to you shortly.
My onboard sound has the 'CD-IN' pins. I'll try and find a cable, switch back to onboard sound with some headphones, and see what happens...
I can get 200pieces for 15€

the MSI is really quiet. barely audible. thats a plus point.
the gainward is loud enough to be heard in the next room with the door shut. and my speakrs have to be on pretty load to drown out the racket.
but thats about as scientific a response as i can give because ive removed both cards and have no intention of inserting either of them again. sorry
He wasn't actually talking about fan noise :PQuote:

Yes, as markiemrboo commented this is different issue in addtion to a poor fan of GW-cards.Quote:

If you want to help/test it in a proper manner, please follow the instructions in post #1.
oh yeah, i did have some strange whining noises coming out of my speakers for a while. i never imagined it was due to the card tho.
I figured it was due to either some kind of interference from the mess of wires round the back of the pc, so i tidied them up. it made no diference.
then i thought it might be the cordless phone my wife insusted on putting next to the speakers. so i moved it and it stopped.
So this odd noise is quite common feature ! Do you still have that sound with your new MSI ?Quote:

Nice job SikaRippa !!! This post answers some questions, or at least gives a way to find a soultion for this 6800LE problems.
I only want to describe my case and share with you all with my observations. I also ask you for eventually answers or comments about it. I've got GW 2100LE, with the capacitors marked as: 43 470 6E, and I don't expierience these BSs! I can run 3D mark 2003 (2005) many times, I can play some 3D games (Half Life2, SWAT 4, Toca2 etc., Far Cry, Splinter Cell 3 etc.) and nothing – no BS. I run also at overclocked card (355/810 Mhz, 12p,6v) and all is OK. But one thing bothers me, and it happens randomly. Especially when the card is overclocked, and especially in FarCry and Splinter Cell 3 – I get these “hang ups” with very high and annoying noise in loudspeakers. The game freezes for few seconds, and mainly freezes for good (Splinter...), sometimes it goes further (FarCry). Always I am able to back to the desktop though. As I said – I run on 4 unblocked pipelines and higher then default freqs. but it happened on default parameters as well.
What do you think about it? Is my card faulty? What should I do next?
Thanks and best regards...

Hi ! Do not worry about language, I am not also native English speaker and wonder the guide might be 'very bad language' for native speakers - but I do not care, since the most important think (for me) is the information itself !Quote:

- Is you card looking like the figures posted (which one) ? If not could you post a figure of it OR provide a link to web-page having such figure OR explain what is different comparing those cards ?
- Have you used the card for a long time ?
- Do you think that the noise is similar to those examples ?
- IMPORTANT ONE: when card hangs, is the noise high or low frequency ???
It is interesting that you have encourted quite similar freezing features than 'markiemrboo' (see posts above), it would be nice to know wheather your card has also *fixed* like 'GW version 1b'. I am just wondering IF this fix would remove BS, but makes card freeze sometimes (????).
