Question DRAM voltages - XMP profile vs. running at lower frequency

[Turbonium]

If my memory has the following as part of its XMP profile (at 6200):

DRAM VDD Voltage: 1.40 V
DRAM VDDQ Voltage: 1.40 V
DRAM VPP Voltage: 1.80 V

Can I just duplicate the values safely (obviously not exceeding them) at a slower speed of 5600?

Note: I tightened the timings but left the voltages to default/auto, and stability was an issue (my game crashed a few minutes in, then later I got BSOD). I'm assuming this means I need higher voltages.

Should I just increment it by 0.05 V at a time? Or would it just be safe to skip straight ahead to 1.40 V? I'm guessing it's safe, but not necessary/excessive/inefficient, as I'm only running at 5600.

Help would be appreciated.

(I figure 1.25 V should be sufficient; as long as I find it stable at that voltage, it should be fine to run 24/7, right?)

No one knows the quality of your silicon in this hardware combo to be certain for what X volts works with Y timings. When you say you tightened the timings, how tight? screenshots are worth a 1000 words, can you upload some?

Corsair Vengeance matched pair of DDR5 sticks rated at 6200 at those same timings, at 1.40 V.

I'm currently running the stick at 1.25 V with no issues so far (was unstable at default of 1.10 V with the same above timings).

Will post screenshots later.
