disable loadline and apply a fixed voltage!
No one has news about it ulaTDClimitPerDPM and ulaNoCalcVddcPerDPM?
I've play with aTDCLimitPerDPM table,sounds like auto limit TDC for DPM state,tonight i will make some test...
The values after usMaxVoltage_0_25mv are two, the first 00 is ucEnableGB_VDROOP_TABLE_CKSOFF and the 01 is ucEnableGB_VDROOP_TABLE_CKSON; I think that GB is Guard Bands and CKS is clock-stretching acording to this amd pdf
, and seems related to VDROOP, but I don't have tested it.
Maybe they are only disabling some other vales into the asic profiling table, like:
About the ulaTDClimitPerDPM and ulaNoCalcVddcPerDPM I don't have tested them.
I also have included into OverdriveNTool registry powerplay editor the per dpm ucCKSVOffsetandDisable values, if somebody wants to test. It should work for 590 gpus or previous polaris gpus changing ucEnableApplyAVFS_CKS_OFF_Voltage to 1 into asic profiling table.
It is the 0.2.8 beta11 version, I think it have some problem with the fans profile but tede says is a driver problem, so keep it in mind. Edited:
It seems that 19.5.1 Driver is solving the fans problem, so tede was right.
