MemoryCoin / Re: [ANN] MMC.1GH.COM - GPU mining
« on: January 01, 2014, 01:07:02 am »I have two R9 290s on a 1000 watt power supply that was mining script for over a month. Why does my video card make a chirp noise when I run the GPU miner. I tried it on one GPU only same problem. The temperatures are way lower with this GPU miner than with scrypt. Any suggestions?
Thanks

It is called a coil whine. It happens because scrypt does not stress the VRM's on the card like this does, you may need to up the volts or get a PSU with less power wobble. It is perfectly normal to hear this on cards when being pushed hard.
