Hello guys,

I have a Sapphire RX5700XT reference card and have done the undervolting.

I would like to know what your experience and your maximum settings of overclocking and undervolting.

Indicating which model and settings loaded.

My Sapphire RX5700XT Reference have this settings:

1890MHZ
1000mV

With this settings i have low my temps about 10 degrees.

The memory clock are stock.

Best regards

When I used automatic overclocking it set my memory to 875MHz and my Core to 2150 MHz.

I think my undervolt got set around 1450MHz.

I have a reference XFX 5700 XT

It's Asus C6H, not CH6; Fighting the wars that matter.

With my Sapphire Pulse RX 5700 XT, I'm using these values:

GPU Core Target: 1880 MHz @ 1000 mV (I definitely didn't win the silicon lottery with this one)

Memory @ 875 MHz
Power Limit: 0

Fan Curve:
30º -> 15%
50º -> 25%
65º -> 35%
75º -> 45%
85º -> 65%

Maximum temperatures after several hours playing Shadow of the Tomb Raider:

Do I need any registry hack to unlock undervoltage or wattman is all I need?
Afterburner doesn't seem to work, also I have ZERO experience with AMD cards...

Your power consumption for the XT seems too high for the reported clocks... I'll check mine again later but I remember at least my clocks being around 1900mhz-1950mhz for those 160w.

EDIT: Found a pic.
