64 gb won't run at the same as 32 gb

[madman7]

Hey all,
I went from 32 gb memory to 64 gb memory. The memory is from the same company and same model (G. Skill Flare X DDR5-6000). I could run the 32 at AMD EXPO with DRAM performance mode set at aggressive. I can run the 64 at AMD EXPO but only at AMG AGESA Default. If I try competitive which is less than aggressive it will black screen and lockup on Windows. I don't dare try to run aggressive. AMD EXPO sets VDDIO Voltage (VDDIO_MEM_S3) , DRAM VDD Voltage and DRAM VDDQ Voltage to 1.40V. Any settings that might help get the memory to run at least competitive?

Thanks

Nothing new. More RAM = more stress on the IMC = slower speeds and/or timings. I'd leave it with just expo.
