The Gigabyte Z790 displaying an amber CPU status LED?
Finished constructing a new system this morning, with all components documented. When I turn on the machine, everything appears functional—fans are running, the graphics card lights are on, and the CPU status LED shows a solid amber. However, there is no video output visible on the monitor, whether through the onboard HDMI port in the motherboard or via the video card's HDMI connection. I checked various forums and discovered it might be related to memory issues, so I tried accessing one DIMM (slot B1), but no improvement was seen. I also learned that this specific variant isn’t listed in the motherboard’s compatibility list for the G.Skill Ripjaws S5 64GB (2x32GB DDR5-6400 CL32). Additionally, the M.2 SSD I purchased isn’t explicitly supported (the WDS100T2X0E is listed, but WDS100T1X0E is not). I’ve sent an email to Gigabyte, but they haven’t replied to my tickets opened early today. Could it be a faulty memory or M.2 drive? Any suggestions for further troubleshooting would be appreciated.
Gigabyte responded to both inquiries. Regarding the RAM, it mentioned technically it could work but hasn't been confirmed due to missing testing. For the CPU, a yellow status light usually indicates an issue, though not always guaranteed. If the SSD isn't compatible, that might also trigger the yellow light. The same applies to the RAM—compatibility problems could cause the same result.
Means the mobile device fails to boot due to a CPU issue. The exact error remains unclear, but it could stem from various factors like faulty CPU, defective MBOO, or insufficient RAM. This scenario is unfamiliar to me. Since the system doesn’t require any drive to start up, removing the SSD might help verify if the problem lies there. That’s feasible. Yet, Intel systems tend to handle RAM mismatches well, so I’d consider other options first. The repeated message about being out of stock isn’t helpful—next time simply inform them you used RAM that wasn’t in stock, as they can’t confirm its status.
Thank you for your message. I haven't assembled a PC recently. Could you share some ideas on how to assess the situation? If the CPU or motherboard is faulty, are there steps you can take to determine the issue? Since I don’t have spare parts, what options do you have?
In this situation, it's unclear which component is defective. You have two choices: return both the motherboard and CPU for an RMA or send them to a repair shop to identify the issue. Initially, clearing the CMOS is recommended if you haven't done so already. It could be beneficial.
Why would you clear CMOS? I'm curious about the outcome, just wondering if it could complicate things further. Also, I've removed the CPU cooler, the SSD, and one of the DIMMs. What remains are the single DIMM (I think it's the correct slow, A2) and the CPU. I double-checked that the RAM is properly clicked in and I took out the CPU before re-seating it.
Everything stays the same...
Interestingly, I also noticed there are no beeps when I start it up. That seems unusual. I attempted to connect headphones through line_out on the mobo and headphones on the front panel, but still didn't hear anything.
If mobo is hanging up during device recognition, clearing CMOS might assist. It’s one of those situations where you think it won’t help but it’s only a short wait—let’s give it a try. See what happens below; also note that the board isn’t posting properly. This isn’t the correct procedure. To hear the motherboard beeps, you must connect the speaker on the motherboard to a specific header. Tip: it’s often provided with the case instead of the motherboard itself.
Understood, thank you! I'll attempt to reset the CMOS and observe the outcome. Regrettably, this model (Fractal Design North) lacks that speaker. It looks like a low-quality part, possibly removed from the system.
Just a note, I realized I needed to join the two 8-pin CPU power cables. I wasn't aware of it before. Everything is now functioning correctly.
