PC Stops Running Dual Channel Now
PC Stops Running Dual Channel Now
I assembled this system around a year ago and everything functioned well initially. After six months it stopped booting into Windows. The EZ Debug LED lit up on the motherboard, pointing to a DRAM problem. Troubleshooting revealed dual-channel mode wouldn’t work. Each stick operated correctly on its own in any of the four slots. I replaced them with Patriot Memory Viper 4 Series DDR4 sticks (2x4GB, 3000MHz). They performed well for about six months. Around three weeks ago I upgraded to Corsair Vengeance RGB PRO 2x8GB 3200mhz sticks. They worked fine for the first couple of weeks but then the issue returned—dual-channel failed and both sticks functioned independently in all slots. I also installed a SK Hynix 1TB M.2 SSD at the same time. Please assist with the CPU situation.
Check both controllers and see if the system boots normally without changes to memory settings.
Turn off the dc power and verify functionality. Position sticks in slots A2 and B2. If successful, configure frequency, apply 1.35v drive voltage, and adjust primary timings manually. If issues persist, download Aida64 via motherboard → SPD section. Record timing details and capture photos. Ensure the page is expanded to display all timing labels. Access BIOS and enter the recorded settings.
There are no new updates available. Your issue with the b550 gigabyte remains unchanged. Please let me know if you need further assistance.
