I'm running: ASRock Z87 Extreme 4, Intel i5 4670K, and 2 x 8GB DDR3-1600 9-9-9-24 1.50V.
It is very unstable at the main board's own "Turbo 4.2 GHz" profile (paging errors, and consequential filesystem errors) but no faults are found by memory tests. Manually changing the DDR3 to run at 1333 makes it much more stable, with two blue screens in a week.
Blue screens usually occur when the system is not under load.
What should I tweak first to troubleshoot this?
1. Relax the RAM timings a bit, 1600 10-10-10-27?
2. Up the memory controller voltage,
3. Reduce the memory controller's speed
4. Remove the overclock entirely, and try XMP presets again?
5. Something else?
At what point should I think the RAM might not be up to its rated speed?
p.s. The "Turbo 4.2 GHz" setting gives:
CPU All-core ratio: 42 x 100,
CPU cache ratio: 39
I locked BCLK ratio to 1, and BCLK/PCIE to 100.
CPU Input Voltage is 1.9V, LLC level 2.
The adaptive voltages are set in such a way that editing cannot reproduce the values.
