Fixing stability and crashes for Vastarmor Radeon RX 9070 XT?
Using a top-tier RX 9070 XT only to have it crash on a beta loading screen is just laughable—the disconnect between the hardware power and software stability is a joke. The Vastarmor Super Alloy was hitting a wall during massive asset loads because the motherboard's PCIe lane voltage was dipping around 0.85V, triggering a storage controller checksum error that nuked the whole system. I first tried limiting the CPU core count in Windows, which stopped the crashes but slowed down loading times by half—a total waste of time. I eventually went into the BIOS, forced the PCIe link speed to Gen4 instead of 'Auto', and set a PCIe voltage offset of +0.03V. In CrystalDiskMark, the read errors (which were hitting 5 per hour) dropped to zero, and the crashes vanished. I did notice the SSD temp spiked to 75°C after the voltage tweak, but installing the OEM heatsink and tuning the fan curve brought it back down to 60-66°C. CPU temps stayed around 65-71°C. I exported this voltage and driver combo as a backup, and the CPU is holding steady at 65-71°C.
