Gigabyte 570 OC Windorce 3x and MSI 570 TwinFrozr II both use the reference PCB design with 6 phase VRM (4 for GPU and 2 for memory). They simply put a custom cooler on top. MSI cards have similar incidents reported....
Gainward 570 Phantom, Gainward 570 GS Goes Like Hell, Palit 570 Sonic Platinum all have 8 phase VRMs (6 GPU and 2 memory). Same amount with the GTX 580. All these cards have identical PCB since they belong to the same graphics card manufacturer group.....
- Asus GTX570 DirectCU II also has 8 phase VRMs (6 GPU and 2 memory)
And so far I havent seen similar incidents with any of these cards on the net. Which really brings me to the conclusion that this problem is only for the reference design 570 PCB with insufficient VRM phases.
