That's why I use dimm watercoolingThat's my bottleneck as well, that trade off.
Like, I need more voltage to be stable but then it gets hotter and makes it temperature unstable. So I lower voltage, temps fine, now it's voltage unstable..
I hate B-Die and it's temp sensitivity.. Max I can run in the summer VDIMM wise is 1.50v. That tops at ~45c which is still stable but 1.53v (for 4500C17) gets to 48c and that is the point at which my DIMM'S go "nope".
