Issue with CPU indicator flashing while DRAM remains illuminated on B650 Eagle
cpu - ryzen 7600 x
motherboard - gigabyte b650 eagle
ram 16 gigs 2×8 4800 mhz essential
plus 16 gigs 6000 mhz team group
gpu 9070xt xfx mercury
psu gigabyte ultra durable 750 gold
plus 400w bronze
both cpu and motherboard are brand new because of another rma problem, hoping to avoid another return issue
attempted basic troubleshooting such as re-mounting cpu ram in all slots with both single and dual channel.
trying to short the power switch instead of the reset switch only shows cpu error if reset remains active.
i’m unsure what else to do since i don’t have a usb drive, and i’m considering buying a new cpu or motherboard to test components individually, but i can’t afford it or wait 2-4 weeks for rma return.
please help.
also, the cpu fans start, but the gpu lights are on while the gpu fans stay off, and there’s no video output detected.
Avoid combining memory! Discard all other DIMMs, retain only one DIMM in MoBo and verify if the build functions, then perform POSTs and boot to OS.
With DDR5 technology, there are no single-channel configurations. Each DDR5 DIMM contains two 32-bit lanes, effectively making it dual-channel even with a single DIMM.
DDR4 systems, featuring only one 64-bit channel, were indeed single-channel when using just one DIMM.
Proceed with breadboarding the assembly.
Move the build out of the PC case, place MoBo inside any cardboard box. Disconnect the GPU and all storage drives, including the OS drive. Install only the single DIMM in the correct slot (typically the second slot from the CPU, but confirm according to the MoBo manual). Connect the monitor to MoBo, and attach the 24-pin ATX and 8-pin EPS power cables. Use your Gigabyte PSU as the power source; the alternative 400W PSU is insufficient. Connect the keyboard and mouse, and connect the power pins on MoBo with a short circuit between the + and - terminals to enable startup. Check if the system powers on and boots into BIOS/UEFI.
Breadboarding steps:
Spoiler:
Follow this guide (click here for details).
This process demonstrates how my Aurora and Astral builds looked during the initial component assembly, including breadboarding and configuration updates.
They didn't combine them separately because I believed the ram was the issue.
I don't understand what breadboarding is. Also, tried what you mentioned earlier, but it didn't work. When I was home before writing it, it didn't boot to BIOS.
If even the simplest components—CPU, motherboard, RAM, and power supply—fail, then one or all of them are faulty.
Take the PC to a repair shop for diagnostics and repairs.
Alternatively, return the CPU and/or motherboard via RMA.
Without proper testing, it's impossible to identify which part is defective.
After acquiring the replacement parts, test them with minimal setup before installing the new components into the case.
Breadboarding refers to the process of connecting electronic components without soldering, using a flexible board that allows easy adjustments and testing.
I have already tried that approach:
The concept is to build the simplest setup possible—just CPU, CPU cooler, motherboard, one RAM DIMM, and power supply. A keyboard and mouse are for BIOS navigation, while a monitor is used to view the image.
Take a look at the image I shared about my breadboarding. Upon closer inspection, you’ll notice I’m only connected to the motherboard via the monitor, KB, mice, and Ethernet (the latter required for installing Windows 11). There’s no GPU in the motherboard. Since my CPU (R7 9800X3D) includes an integrated GPU, I can view the image directly. I also have power connected—24-pin ATX and 8-pin EPS (the red, Cablemod paracord sleeved cables).
