Z77 Sabertooth Problems

post #1 of 5
Thread Starter 
Hi guys,
Hoping to get some advice from here as I'm close to tearing my hair out! thumb.gif. Apologies if its a little long winded....

Anyway, I had a Q6600 with a P5Q Pro motherboard and GTX460 gpu. Ran for years without any problems. Started to feel slow with the games I was playing so I decided to upgrade to Ivy Bridge and Z77 board. I opted for the Sabertooth and 3570k and also purchased a AMD 7970. This was all going to go under watercooling as my aim was to have a silent setup. I also purchased a XFX Pro 1050w which turns its fans off to help achieve this.

With the 7970 on order I ran my system with the GTX460 which had no noticeable issues. The psu made loud whining noises which were easily audible over the case fans. This was RMA'd and determined faulty (coil whine) with a new unit bieng shipped out. The current one still makes the same sound although it is not as loud. Once the 7970 was installed I noticed a very loud squealing and crackling noise coming from inside the GPU area of the case. I thought it was the GPU so I sent it off for RMA (hasn't been tested yet). However, when I put my 460 back in, the exact same sound was reproduced.

I have tried using 3 separate PSUs, each one results in the same squealing and crackling noises at the gpu area. I was told by the retailer to take the gpu out and check if the squealing noise is reproduced. Obviously no sound was produced but that was because it was using the on board graphics. I didn't spend close to £800 on 3 components only to run games off the iGPU! Testing the GTX460 on another computer yielded no squealing issues so that card is not faulty. It is only when it's connected to the sabertooth and under load it (or the mobo) makes a sound. Running the windows aero benchmark and any game reproduces the sound but on idle it is silent.

The retailer is saying swapping the mobo won't solve any problem as it is the combination of all the components that contributes to the sound. I argued my point saying that regardless of using 3 different PSUs and 2 different GPUs (i.e. many different combinations of components) the problem still exists. Can anyone advise me which component is causing the issue?

Thanks in advance...

Have you stripped off any of the motherboards covers to look underneath? If you are 100% sure it has nothing to do with your psu's or gpu's then i can only think that a componant on the board is making the noise. What make and wattage psu's were you using?

Do you have any fans installed that could be rubbing on something?

Hi Chewy,
Thanks for the reply. I've not stripped away the motherboard cover yet as all the piping for watercooling is in the way but I'll have a look when I have some time. The PSU's I was using were the XFX Pro Series 1050W and the OCZ StealthXstream 600W. Currently the computer is completely passive (at idle) apart from the GPU fan so I'm sure it is not an issue with any fans.

Those are good quality psu's so i'm sure we can rule those out.

As you have tried various gpu's it does seem like the board is the likely cause, I would take the board out of the case and set it up on a bench and see if the same thing happens, If it does you have your answer. Are you sure it has nothing to do with any of your watercooling loop? noisy pump perhaps? air in the system?

Agreed, it all points to the motherboard, the same combination of GPU and PSU has been tested in another system with no issues, it only occurs with the Sabertooth. It is not due to the loop as the pump is on a low setting which is virtually silent and the loop has been bled of air. I've emailed the retailer regarding an RMA as it looks like the best way to proceed is to test a new motherboard. I'll keep the thread updated on any changes but thanks for your input Chewy so far smile.gif.
