Fixing Crucial DDR5 4800 voltage instability in Ishin
I couldn't stand it anymore—even with low-frequency 4800MHz RAM, the game would just crash after two hours of play. The default voltage on Crucial DDR5 4800 fluctuates too much on some boards, causing transient voltage drops when switching between low and high loads, which triggers the game's memory protection. I tried updating the BIOS to the latest version first, but that was a disaster; the crashes actually happened more often. I eventually went into the BIOS voltage settings and manually locked VDD and VDDQ at 1.2V instead of the Auto 1.1V. In Prime95 Large FFTs, the system ran for 12 hours without a single error, and the crashes in Ishin completely vanished. I tried pushing it to 1.3V at first, but temps spiked to 65℃, so 1.2V is the sweet spot for stability and heat. Memory temps now stay between 48-54℃ at 4800MHz. I used the motherboard's profile save feature to back up this config so I don't have to do it again.
