With this 840 G3 works perfectly fine for BS 11.2.3, but cannot get updated to 11.4 (starts boot then reboots, never getting to GUI)

That is OC 0.6.6 (I suppose it must be updated to 0.6.9 for 11.4, but never got round to it yet) (even OC 0.6.5 is OK for 11.4)

edit:

In the end I simply gave up on this update

Instead used full 11.4 USB installer (with same OC 0.6.8 EFI) and upgrade/update worked perfectly fine
