Didn't mod this card, I only used MorePowerTool to be able to reduce core voltage and to adjust the fan curve
I read some comments, included yours, about difficulty to modify the bios of these Gigabyte cards, and I prefer to leave untouched
If I brick this card I won't have warranty, so I'm happy with the hashrate of 54.5Mhs and under warranty for 3 years
Oh alright. Thanks!
After bricking it, I was afraid to use MPT as well to increase the Memory frequency and reduce the voltage.
Will try this now!
