Optimizing RAM timings for MSI MPG Z890 EDGE TI WIFI in MHW?
It's honestly ridiculous that a high-end board like this would let my frames collapse while loading Elder Dragon areas. The memory controller on the MSI MPG Z890 EDGE TI WIFI was swinging between 60% and 95% bandwidth utilization, causing these brutal 1-2 second freezes. I tried bumping virtual memory to 64GB, but that just made the whole OS feel sluggish—complete waste of effort. I went back to the BIOS and dialed the XMP profile down from 6400MHz to a more stable 6000MHz, while nudging the DRAM voltage from 1.35V to 1.38V. In AIDA64, the read/write bandwidth stopped fluctuating between 82-91GB/s and locked in at 88-90GB/s. The loading stutters are completely gone. I had a couple of reboots at first because the timings were off, but loosening tRAS to 88 fixed it. RAM temps are 48-55℃ and VRMs are 52-58℃. Exported the logs, and the bandwidth is finally flat.
