If you have more than one module, swap them, see if the fault moves to
the other bank.
Then, if it does, the memory module might be faulty, or, incompatible to
the mainboard.
If the fault remains in the same bank, or, if it appears randomly, i. e.
sometimes in any bank, sometimes it works, check the supply voltage for
spikes. Once the capacitors inside the power supply, or, on the
mainboard leak, their capacity drops down, causing excessive noise on
the supply voltage. This will typically lead to a system hung, or,
random memory faults. Checking the supply voltages can be done using an
oscilloscope (ac mode), or, a RMS voltmeter set to ac (to get just the
ripple). Compare the results with them of a good power supply.

Makes perfectly sense, the memory fault causes thinks like this. Since
Kingston is pretty good stuff, if compatible to your system, a power
check might really be a good start chasing that fault.

Good luck
