Low hissing noise frequency coming from Mobo

[Scrullet]

I had previously posted in the overclock section because after about 3 years of my system overclocked, it started to turn itself off regularly. Even when idle on desktop. The problem seemed to stop when I turned off my clocks.

See thread below.

Anyway, since it started happening a week or so ago, I've been noticing a strange hissing or bzzzing quite faintly in my case. I removed all components and even my Corsair H50 to eliminate that from the problem. I installed a stock heatsink and removed all dust etc and the hissing still persists. It's coming from around the top area of the CPU/Capacitors. Could this be my issue for an unstable overclock? Seeing as it ran stable at 4Ghz for the past 3 years.


Any thoughts would be greatly appreciated.

The UD3R V1 was renowned for mosfet problems with overclocks.

Thats why the V2 had much better VRM and power delivery

Cheers for the reply Tom! I forgot to mention that I have the rev 2.0 version. Think if I replace the board I could have some luck?

Well my 950 eventually just stopped overclocking.....

It will be difficult to work out whats what without changing the mobo. Its not worth spending much on though.

It may be time to start thinking about changing to 1155

Yeah, that is the plan eventually! Currently saving for all the parts. I was only worried about the hissing incase it could damage any other components? I was going to replace it with a cheap board for the time being.

The hissing is common when capacitors start to fail. When you overclock they have to provide more power than when you don't and over time they will degrade, definitely much quicker, when you are overclocked.

Gigabyte offer a three year warranty on boards IIRC (that's if it's the same as GPUs) but a mate of mine sent his back recently and they did not have anything to replace it with so they sent him an X79 board. Nice of them of course, but inevitably useless when it came to him sticking with his I7 920.

As for the hissing damaging the components? well if the capacitors are on their way out (and it sounds like they have failed hence the unstable power delivery/overclock) then yes they could damage your CPU (I would imagine it's the CPU power delivery area that's developed a fault).

As I say if you've had it less than three years and have a receipt I would RMA it. Gigabyte are pretty fantastic when it comes to warranty.

It's just symptoms of an overclocked system in the long term really. Most never notice it as they don't keep the stuff for long enough but it's pretty much the reason why I don't overclock anything any more as I want it to last the long term.

Thanks for the swift and awesome response AlienALX. I'm going to look into sending it back then. Pretty sure I still have my overclockers.co.uk receipt of purchase.

Awesome. They may even repair it tbh. I've seen the same board sent back before (only working of course lol).

Definitely so.

Are you sure it's the mobo and not another component or the psu?

Not to stress the point or add drama, but you are in a situation. You want to get your data backed up as soon as possible, but doing so may actually put enough load on the system to tip it over. Depends on how long it's been like that.

Bad capacitors where a big issue a few years ago, when a lot of cheaper sub-standard (incorrectly made alledgedly) capacitors entered the market from Taiwan. That's why you see mobo manufacturers boasting about Japanese capacitors; higher cost and more reliable. Looking at your pc components nothing is that old to be mixed up in that issue, so it's probably as you have deduced your overclock that's caused it. A poor psu with high ripple can reduce the life-span of capacitors too.

Heh, I remember that. Affected many Nforce 2 boards.

Pretty sure my board was made in Taiwan. The hissing only accurs around the top of the board. I've even stopped my case fans to identify it clearer. It's a weird hissy frequency and I don't recall it doing it in the past. It's only just occured now that my computer wont overclock anymore.

I'm not too bothered about any data lost. I had re-installed windows as part of my troubleshooting. I had tried redoing my clocks again and stress testing with OCCT but even the slightest overclock was turning my computer off. With low temps too I might add.

I've filled out a Gigabyte RMA form as I believe I'm still within the 3 year warranty. I purchased it on the 27th of August 2010. We'll see what they say when they get back to me.
