AMD Rog Strix B550-F gaming fails to boot with dual-channel configuration – yellow LED indicates Dram remains active
Hey there! I see you're dealing with some tricky issues with your rog strix b550 f gaming rig. The yellow LED for DRAM stays lit but the PC won't even power up. Your specs look solid: a 5800X2 CPU, GTX1070 GPU, Corsair Vengeance LX RAM, and DDR4 3200 MHz. You mentioned updating the BIOS with a USB stick, but now you're only getting a boot when using RAM in slots 3 and 4 or just slot 4. That sounds like it's stuck in single-channel mode.
You said it worked fine in dual-channel before, which is good news. The RAM seems okay too, since it booted normally then. I noticed similar problems with your b450 tomahawk max—still no fix yet. It’s possible the CPU is fine, but the DRAM setup might be causing the bottleneck.
Here are some ideas: try reseating the CPU, updating the BIOS to the latest beta, moving the GPU to another slot, booting with just RAM in slots 3 and 4, or even clearing the CMOS. If none of these help, maybe wait for more BIOS updates.
Performance loss in single-channel mode can be noticeable—typically around 10-15% depending on workload. But it really depends on what you're doing. Let me know how it goes!
What kind of CPU cooler are you using? I’ve seen similar issues where someone forced the airflow too much, causing a solder joint to crack on the motherboard.
It's quite quiet in the dark room. The friend has the identical cooler, CPU, and an X570 motherboard. So far, there have been no issues.
If someone has helpful details or knows about a fix, please let me know. It would mean a lot to me. Thanks ahead of time. Apologies for the unclear English.
