with this patch applied (and the debug patch) dmesg output is:
...
[ 107.149105] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 0 vddc:
800
[ 107.149107] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 1 vddc:
900
[ 107.149108] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 2 vddc:
910
[ 107.149109] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 3 vddc:
920
[ 107.149109] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 4 vddc:
930
[ 107.149110] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 5 vddc:

[ 107.149111] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 6 vddc:
950
[ 107.149112] amdgpu: [powerplay] vega10 SCLK vddc_lookup_table state: 7 vddc:
980
...
And the soc voltage under stress stays at the set value:
# cat /sys/kernel/debug/dri/0/amdgpu_pm_info
...
GFX Clocks and Power:
800 MHz (MCLK)
1541 MHz (SCLK)
1269 MHz (PSTATE_SCLK)
700 MHz (PSTATE_MCLK)
981 mV (VDDGFX)
161.0 W (average GPU)
