How to stabilize Crucial DDR4 3200MHz for S.T.A.L.K.E.R. 2?
Getting a black screen and a full reboot is the worst, and it turned out to be signal instability. The voltage on my Crucial DDR4 3200MHz was fluctuating between 1.2V and 1.35V, which triggered checksum errors while loading the massive open-world assets. I tried downclocking to 2933MHz first; the crashes stopped, but the FPS drop was way too noticeable for me to accept. I went back into the BIOS and locked the DRAM voltage precisely at 1.37V, keeping the temps stable between 44-49℃. Interestingly, the voltage bump alone didn't fix it; I had to disable CPU power-saving states and lock the clock speed before the memory controller actually behaved. CPU package power stayed around 78-85W, and the motherboard heatsinks felt warm to the touch. After a grueling 4-hour stress test, my memory latency improved from 72-78ns down to 65-69ns. The power delivery is finally sorted and the temps are holding at 44-49℃.
