Yes mine boosted at stock mem and boosted with manual mem speed and timings. Did not boost with Auto mem and XMP, did not boost with any vcore modifications (+offest, -offset, manual override)Oh, that's a curious idea. Set the voltage to work at all, return to auto, set timings manually? Will check that, just need to get myself the XMP table on my phone.
But did it boost on stock? Without the XMP? In my case there is completely no difference between the 3600 XMP and stock JEDEC 2133.
Edit: set MHz, volts and timings same as XMP to check whether that would make the CPU boost. No luck at all. Still works, but still on 3800MHz. (Yes, dialed it back from before when setting auto on voltage and clocks).
