Why is my Corsair Vengeance DDR5 lagging in Dead Space Remake?
When pushing into the deeper sectors of the Ishimura, my RAM usage spiked from 22GB to 48GB in under three minutes, which caused these micro-stutters due to instruction blocking. I noticed the memory controller voltage on my Corsair Vengeance DDR5 6000 (48GB sticks) was dipping by 0.03V from 1.35V during heavy asset swaps, causing frame times to jump wildly between 16ms and 42ms. I first tried bumping the virtual memory to 64GB, but that was a total waste of time—it didn't fix the lag and actually added 10 seconds to my boot time, which was beyond frustrating. Eventually, I dove into the BIOS and manually locked the VDDQ voltage at 1.38V while tightening the timings from 36-36-36-76 down to 32-38-38-72. Using Resource Monitor, I saw the response latency drop from 88ns to a steady 74-78ns. The first time I locked the voltage, the sticks hit 56℃, so I had to overhaul my case airflow to bring them back down to 48-52℃. Now, the bandwidth is rock steady at 84GB/s with almost zero jitter. I saved this as a BIOS profile, and it's been flawless since.
