Question DRAM light CPU light reboot loop on a new AM5 build
Question DRAM light CPU light reboot loop on a new AM5 build
So finaly I decide to build a full new setup:
Ryzen 5 7600
Noctua 140mm NH-U14S
Radeon RX 6750 XT
Ssd samsung 980 PRO NVMe
Corsair vengence ddr5 2x16 5600
Mobo msi b650 mag mortar That I swaped for a asis TUF b650 plus
Psu XPG cybercore 1000W platinum
Built the pc, installed windows, and all the necessary stuff. Than the pc started to get unstable to the point it wont boot, was traped in the dram then cpu light and restart loop, but was able to enter the bios and sometimes it would boot, during tinkering it got even more unstable, to the point of losing access to bios.
I tested everything, then I swaped the mobo, in the process I got 2 bent pins, I dont know how, so they dont gave me a refund, at this point I installed the asus B650 plus. Well the nightmare continued, bios updated lots of additional tests and tinkering until I came to the conclusion it was the processor, they gave me a new one. More than 30 days of testing prior to that.
Intalled the CPU on friday, enjoyed the weekend with my new setup, the only config change I did was to set the ram to 5600 on the ai twek on bios (directely on the setings not using DCOP, dumb, but was working, did that becouse I didnt know that XMP for amd is calle DCOP).
Now on monday, pc wont BOOT WTF???? DRAM, CPU light loop, but I can acess bios.
I dont know what to do….
Tryed to reset the CMOS shorting the cmos reset pins, checked if bios is up to date (it is), checked the RAM in diferent slots, they only work in prefered position (2 and 4, or only 2 or only 4), when only 1-3 or 1 or 3 is populated I get a solid DRAM light, no bios access. All the other parts were extensively tested.
The strange part is that it worked fine for the weekend, tryed run several games while checking for temperatures, the only strangish event was my ram sometimes reaching almost 70 oC, but I read thas ok for DDR5.
Now some hypotesis:
-did the faulty cpu fryed the mobo parcialy? And now isnt working properly with new processor?
-did my wrong setup of the memory broke it?
-did the faulty cpu, damaged the mobo, and the mobo damaged my new cpu?
-configuration or assembly mistakes?
Posting this from my phone, last sad fact…
Welcome to the forums, newcomer!
The rams should ideally be placed on slots A2 and B2. For the processor, you might consider running the whole platform without the separate GPU to check for POST and display issues. Also, try loosening some screws in an anticlockwise direction to ease the stress on the cooler.
Updated: took the power cord overnight, the next day I connected it and it booted up, ran some tests (cpuz, afterburner), everything worked fine. Turning off with the cord plugged in, came back from work and it still wouldn’t boot, same issue. Also noticed the CPU light came on, then it restarted repeatedly. Even tried another pair of DDR5 to check, but the problem persisted.
Updated: I attempted all possible methods, focusing on cooler performance and memory stability. I removed the screws of the noctua in several steps, booting through each half-turn until I fully removed them. I inspected the processor and its pins. There was a burn mark from the previously faulty Ryzen 7600. See the images in the link below:

After that, I installed the stock cooler and it worked the first time. Great! I plan to do more testing this weekend.
Now I have some questions:
- The process of removing and reinstalling the CPU seems related to the POST behavior. When I swapped the RAMs, did the POST path change?
- I tried installing the stock cooler because it stopped POSTing when I moved the cabinet. Was there a different POST path when changing the hardware?
- I attempted to install the stock cooler but it halted POSTing when I shifted the cabinet. Also, note that the faulty CPU left a burn mark on one pin without affecting its function.
...
If everything works out, I’ll close this topic and move forward using the stock cooler.
