I also lowered the TDP, but I just used the "eco mode" that my motherboard provides, which either lowers the TDP to 105W or 65W. I also read somewhere that one needs to POST multiple times for the context restore to kick in, which could make sense in my case, as I left it on with EXPO disabled and now it does not memory train any more even with EXPO disabled (at least the POST screen is only visible for like a second and then my OS boots up). But when I set up my system I spent much time fiddling around with the BIOS, so I'm not 100% sure if it is memory context restore that solved this in my case.
