LED lights up and stays active after a restart only.
I have some ideas, though I'm not sure they'll work. Still worth trying, right? My next thoughts are expanding the LLC or boosting the positive vcore. If that doesn't help, I'd like full memory specifications—timings and voltage details. Confirm the die manufacturer with Thaiphoon Burner. All this info can be gathered from a screenshot. We can dig a bit more. Let me know. But I'll need to go over it again tomorrow.
Definitely and appreciate your help here and I am willing to try anything. I just built my PC (1st timer) 3 days ago and while I can use it perfectly fine when I am booted into windows by manually power it off and power on, this red LED issue whenever I restart is really annoying me. I spent weeks of research to pick these components just to get this annoying issue is frustrating. I have also contacted MSI for support but still waiting for their response. So I am new to this but have googled and tried to increase LLC and positive vcore as follow: LLC Mode: Auto > Mode 1 (I googled and it appears Mode 1 is the most aggressive settings) VCore: CPU Core Voltage Monitor: VCC Sense (the other option is Socket Sense) CPU Core Voltage Offset Mode: Auto > + CPU Core Voltage Offset: Current 0.832V > +0.020 All the rest at auto but I am listing the current voltage below: CPU SA Voltage: 0.910V CPU VDDQ Voltage: 1.200V CPU AUX Voltage: 1.840V DRAM Voltage: 1.204V Eventual DRAM Voltage: 1.204V In terms of ram, please see screenshot from CPU-Z before I strip my SSD. It is Corsair ram and is labelled v3.41. Based on that, it seems to indicate ram is Micron die, 16GB per rank, and possibly a B or E rev? If this is essential, I can load back up my SSD and check with Thaiphoon Burner.
Thank you for your feedback. Everything appears to be in good shape. I believe the problem isn't related to memory at this point. I've reviewed some information about your motherboard and found two common suggestions: 1. Re-seat the CPU and cooler—bending is a known concern with socket 1700 over time. 2. Consider replacing the power supply unit. A forum discussion mentioned PSUs designed for Haswell systems, though I'm not certain that's directly applicable. For more details, you can check this link: https://rog.asus.com/forum/showthread.ph...sue!/page4. If you have a PSU available, it might be worth trying one of those options.
Here’s a revised version of your message:
Thank you once again for your response. To give you a clearer picture, the full specifications of my new built PC are listed below. All components are brand new: CPU: i7-12700 (non-K), Cooler: Fuma 2 Rev b Mobo: MSI B660 Tomahawk DDR4 WIFI GPU: Strix RTX 3080, 10GB RAM: Corsair DDR4 3200 LPX (16x2), Storage: WD SN850 2TB, PSU: Corsair RM850x, Case: Torrent Compact Bios version 7D41v27, OS: Windows 11.
Regarding your suggestions, I’ve checked the CPU again and confirmed it’s in perfect condition—no bent pins or issues. My problem only appears during a warm reboot (100%), which works fine on a cold start and under any load when using Windows. If there were bent pins, I’d expect some intermittent problems, but that isn’t happening here.
For the second point, the resource you mentioned seems more relevant to cold boot rather than warm boot. Although I can’t rule out a PSU issue, I don’t have a spare part nearby. I’ll reach out to MSI support locally to see if they can help.
Additionally, the CPU red LED lit up immediately after resetting the system—even when the hardware is minimal (CPU, cooler, 1 RAM). I’ve read that a warm reboot doesn’t trigger POST on this setup, which seems to be the case. This makes me feel like the system might not start POST at all during a warm boot and get stuck with the red LED.
I’ve searched extensively online—over 50 threads over the weekend—but haven’t found a solution that matches my situation. I’m hoping someone else has encountered a similar issue and could offer guidance.
