How to calibrate memory stability on Onda 9D4-DVH?
Just as a massive dragon was about to roar in my face, the game vanished—another random crash to desktop. I did some digging and found the memory controller on the Onda 9D4-DVH was having timing drifts of 6.2-8.5ns while running at 2400MHz. I tried the 'Auto Overclock' in BIOS first, which was a disaster; it sent me into an infinite boot loop. I learned my lesson: don't force OC on old platforms. I manually bumped the memory voltage from 1.2V to 1.25V and loosened the timings from 16-16-16 to 18-18-18. After four consecutive passes in MemTest86, the error count dropped from 22 to zero. Sure, map loading takes about 2 seconds longer now, but at least I can actually finish a hunt without the game dying. Memory temps are at 42-48℃ and the CPU is steady at 64-70℃. Switching the power plan to 'High Performance' made everything feel a bit more awake. Frame times are finally stable at 8.2-9.5ms.
