Alright been trying the latest 0.4.4 trm and getting mixed results. On the one system I have with the 3 vega 56, only one of the video cards is at 2130, but the other two cards are hashing at their normal rate. The thing is when i run the AMDmemtweak, it tells me it changed the settings for all 3 cards. I even went back and added a --i 0,1,2 and that again it tells me i updated all of them but when i run the miner only 1 gpu is running at the increased rate.
I'm also having issues with running the memtweak on my other miners, they are all having pathing issues, even though i know i'm typing everything correct. All the settings are the same with the one pc that i have amdtweak working. So im not sure whats going on there.
But i do have reports for the 1 gpu that is mining with the memtweaks, it has been hashing for two days now at a sustained 2130 rate and with a pool side hashrate of around 2030. I havent been able to do much yet but will get power readings later. I can say that the temperature of that one card is sitting at 66c while my other 2 cards are at 51c, which does suggest a higher power draw.
Super quick update #1
I was finally able to run the program by going to cmd as an admin and typing in cd c:\
hitting enter, then finally typing WinAMDTweak.exe and going from there.
So far I was able to apply the memory setting to two of my other x3 vega 56 rigs. These have different firmware on them. One has the 18.0.5 and the other the 18.0.6. So far they been stable but the hashrate increase in CNr has been much less than it was on my other computer. I'm thinking the drivers maybe? Hitting around 2k on all 3 vegas with the AMD 18.0.5 drivers, and between 1910-1990 on the one with the 18.0.6 drivers. Thats still a bit higher than their original setting but not by much.
miner settings and amdmemorytweak settings are the same with all cards.
