I have a Maximus V Formula motherboard, 3770K cpu, 980TI gfx card, and 16 GB of Corsair Vengeance RAM.
I have been running stable for years, and I had a Windows 10 update the other day. But after it did its preloading, it did not reset, just shutdown. I tried resetting and powering on and off a few times, then I noticed it was showing a qcode 32. I put a single DIMM in the A2 slot, then things started getting weird. It started cycling in an endless loop: qcode 14, 15, 20, 36, and If I let it go for a minute, would add 03. The CPU and RAM LEDs would cycle back and forth. If I try to boot without RAM, I get qcode 55. I gutted my whole system, did a thorough cleaning, cleared the CMOS including removing the battery for the duration of the cleaning. Put it back together and get the endless cycling of qcodes. I have been running stable with this setup for years, so I find it hard to believe that all 4 DIMMs failed randomly and at the same time.
