Hi everyone! I'm dealing with some intermittent POST issues on my ASUS PRIME B650M-A AX6 motherboard, which is paired with a Ryzen 7-7700X processor and G.SKILL F5-6000J3636F16GX2-TZ5NR (2x16GB) memory. The RAM is officially supported, and while the EXPO I profile mostly works, sometimes my PC fails to POST after a minute or two, forcing a reboot and often landing on a POST recovery message that reverts back to the JEDEC timings. I've noticed that when I use the JEDEC speeds (4800), the machine POSTs much faster without issues. I'm considering enabling memory context restore to possibly help with boot times, but I've seen mixed reviews about its effectiveness. Lately, I've observed that my SoC voltage (set to auto) hovers around 1.24, while VDDIO is around 1.376. Although many suggest achieving 6000 MT/s CL30 with a lower voltage, like 1.2, my system won't even POST at that. Since these specs should be manageable for the Ryzen 7 7700X, I'm left wondering if it's an issue with my motherboard's quality or maybe my luck in the silicon lottery was less than ideal. Has anyone else experienced this with an ASUS B650 board? Any tips or solutions? Thanks!

It sounds like you might be dealing with the notorious silicon lottery, which can really impact overclocking stability. EXPO/XMP settings are kind of hit or miss since they are essentially overclocked profiles, and perfect stability isn’t always guaranteed. One thing you should definitely check is whether your RAM sticks are in the recommended slots according to your motherboard manual – it might be counterintuitive, but slots further away from the CPU socket are often preferred for dual-channel memory configurations.
Thanks for the tip! I’ve already confirmed that I put the DIMMs in slots 2 and 4 as recommended.
