I've recently purchased a G.Skill F5-6000J3636F16GX2-FX5 32GB RAM kit (2x16GB), but I'm having issues getting it to post when using AMD EXPO settings. My CPU is a 7600X3D, and I'm using an ASUS B850i motherboard. I'm fairly certain it's a RAM problem because I've tested another RAM pair (Micron 2x32GB) that works fine in the same system. The G.Skill RAM also fails to post on a different motherboard.
I even exchanged the RAM for an identical kit at Microcenter (couldn't swap it for another model as it was part of a bundle), but I'm facing the exact same issue. With EXPO settings disabled, the system boots without issues. Interestingly, I can make EXPO 'work' if I set it to EXPO and reduce the speed manually from 6000MHz to 5600MHz, but 5800MHz fails as well.
I've also tried increasing the memory voltage from 1.35V to 1.4V while set at 6000MHz, but it still won't post. Does anyone have any suggestions?

It sounds like you might be hitting a compatibility snag with the memory profile. Some RAM just doesn't play nice with certain motherboards or CPUs using EXPO settings. Try checking the official compatibility list for both the motherboard and RAM. Additionally, you might want to update your motherboard BIOS if you haven't done that yet. Sometimes newer BIOS versions improve RAM compatibility. Good luck!
If you've already swapped the RAM, it's less likely to be a defective stick. You could try testing the memory in a different slot on the motherboard, just in case there's an issue with the slot itself. And if that doesn't work, lowering the speed like you did might keep it stable, but it's not ideal if you want to utilize the full speed of your RAM. Hang in there!
Trying different slots is a good idea. Also, ensure that your motherboard's settings are correctly configured for the RAM speed.
Definitely check for BIOS updates! Also, have you tried tweaking the timings manually? Sometimes that can help get things stable.
