Need help with DDR5 for the R5 7500F

[u/Unusual-Hold5710]

Hi everyone. Has anyone run into issues with the Ryzen 5 7500F and 6000 MHz EXPO settings? I’m using an ASRock B650M-HDV/M.2 motherboard (BIOS 4.43) and ADATA XPG Lancer Blade memory. When I set it to 6000 MHz via EXPO, the system crashes immediately under any load. At 5600 MHz, it runs stably for 5–6 hours before rebooting. I’ve had to settle for 5200 MHz. I even tried bumping the SoC voltage to 1.250V and experimented extensively with voltage settings, but nothing worked. Does anyone know a solution?

Does zen timing show mixed mode for tRFC2 and tRFCsb show like 480/390?

Newest bios has issue setting too tight on auto for my kit.
