What is a normal temperature range for DDR4?
My memory is Trident Z Neo F4-3600C18D-32GTZN. From start its temperature is already at 48 degree and can rise up to 57 degree when running game. Is this normal? (With DOCP turned on and no O/C)
Anyone pls, what is your average ram temperature?

Yes, that is normal / average for DDR4. Extreme load such as stress test can be near 80 degrees
