It's generally accepted you don't fix working machines. It can introduce hard to pinpoint issues like this.
After a year the heatsink compounds harden and it could be as simple as these are not working as well as before. Only a new tech points to temps. The seasoned tech redoes the work.
Tell more about why this was done.
Hello,
Last week I reassembled my PC. Dual channel wasn't working at all before. Now it is. I also cleared CMOS after the reassembly. PC started freezing after 2 days of flawless experience. It freezes with buzzing sound, pixelated screen and code 04 (same thing happens when I remove RAM from slot A2 while the PC is running) or with code A0, which is more like complete lockdown. In both cases hard reset is needed. I figured out that I can give it temporary fix by reseating the CPU cooler. Then it works for a day or two and then start crashing again. Please mind that the exact same PC was running smoothly for about an year before in single channel. The bad thing though is that it now isn't working in single channel either.
Thank you for any clues.
My PC:
mobo: Asus Maximus VIII hero
RAM: Corsair Vengeance LPX 3000Mhz
CPU: Intel core i5 6600k
GPUs: RX 570, 1070 GTX
PSU: Corsair RM 650x
