Don't GS - I could not even get them stable at 3400MHz mate. Relaxed timings, even had the voltage up to 1.5 but no joy. Same bloody DDR4 that we used at Cambridge (don't think you made that event) what was it three or four years ago. Just pleased that I got dual channel to work. The fist set of DDR4 ram I played with, were original DDR4 and could only get one stick working at a time. LOL
Good to see how well you have done mate. Very pleased too see you kicking butt and taking names in the benching scene.
