should we remove any MPT modification with the current GPU BIOS for R-mode to work or to be stable?


I followed this for MPT and use APPLE Straps.

- Under Feature Control, set:
DS UCLK: Check (Enable)
GFXOFF: Uncheck (Disable)

- Under Overdrive Limits tab, set:
GFX Maximum Clock 1440 MHz
Memory Maximum Clock 960 MHz
Power Limit Maximum 0%
Power Limit Minimum 0%
Memory Timing Control 1 [For computing (mining), default is 2 for gaming]

- Under Power and Voltages, set:
Maximum Voltage GFX 1050 mV [must not be lower than this as the MVDD default value in the vbios is at 1350 mV and the VDD must be within 300 mV range with MVDD or components may get degraded and permanent damaged]
Maximum Voltage SoC 1050 mV [must not be lower than this like the Maximum Voltage GFX]
Minimum Voltage GFX 750 mV
Minimum Voltage SoC 750 mV
Power Limit GPU 126 W (120 W for non XT)
TDC Limit GFX 110 A (105 A for non XT)
TDC Limit SoC 12 A (10 A for non XT)
(If 126 W was chosen for Power Limit GPU then for TDC Limit GFX is 110 A)

- Under Frequency tap, set:
GFX Maximum 1260 MHz
Memory DPM 3 - 910 MHz

- Under Fan tab, set:
Zero RPM Enabled: Uncheck (Disable, for those who have high memory temperature)
Stop Temperature: 50° C
Start Temperature: 60° C
