How to optimize memory bandwidth on ASUS ROG STRIX Z890-A Snow?
The memory bandwidth on this setup was a joke; despite having a top-tier Z890 board, loading certain scenes felt like I was running single-channel memory before it just froze. The signal integrity on the Snow edition felt shaky at 7200MHz, with the memory controller hitting massive delays of 115-140ns during peaks. I tried lowering all the graphics settings, but the game looked like a pixelated mess from ten years ago, which was just masochism. I went into the BIOS, disabled Gear Down Mode, and manually bumped the SoC voltage from 1.2V to 1.25V to kill the signal interference. According to the logs, peak bandwidth jumped from 55GB/s to 68-75GB/s, and those infuriating freezes finally stopped. Disabling Gear Down Mode caused some random reboots at first, so I had to loosen the primary timings by 2 counts to get it stable. RAM temps are 50-58℃ and VRM is 62-68℃. Everything is archived in the monitor tool, with fans humming at 1400-1600RPM.
