I'm having a bit of a frustrating problem with my AM5 setup, where I occasionally get a no-POST issue. Here's the breakdown:
**System Specs**:
- **CPU**: AMD Ryzen 7 7700
- **Motherboard**: Gigabyte B650 AORUS ICE AX
- **Memory**: 32 GB DDR5 (2x16 GB) ADATA XPG Lancer Blade, 6000 MT/s CL48 (only EXPO enabled)
- **GPU**: Sapphire NITRO+ Radeon RX 7900 XTX
- **PSU**: DeepCool PX1200G
- **System Age**: About 1 year
**Timeline of Issues**:
- **Day 1**: The system lost video output while idle but powered on; a restart fixed it.
- **Day 2**: On a cold boot, I got no video output and noticed the DRAM LED was lit. Swapping DIMMs helped initially, but later it failed to POST again. Tried Clear CMOS but still no luck.
**Current Situation**: No video output, DRAM LED lit, and the DIMMs aren't helpful anymore. The fans also spike to 100% during failed boots, which is new for me.
I've only changed BIOS settings to enable EXPO and Secure Boot. I'm not really sure where to go from here, especially since finding compatible DDR5 to test hasn't been easy. Any thoughts?

Just a heads up, I had a similar situation where replacing the RAM didn’t fix the problem. If you’ve tested a different DDR5 kit and are still seeing the same no display and lit DRAM LED, that could indicate something else is off, potentially on the motherboard itself or the CPU.
Have you tried booting without EXPO enabled? Sometimes RAM that's technically compatible can run into issues with certain settings, even if it's been stable for a while. Also, check the RAM compatibility list for your motherboard just in case.
I already checked the QVL and it seems my XPG Lancer Blade isn't listed. But you're right, it worked fine for months. I'd like to try without EXPO, but I can't access BIOS since there's no video output at all. I even did a full Clear CMOS, but it didn't help.
