Right now the single stick is running steady at A2.Submit Build Help/Ready post Submit Troubleshooting post Submit other post New Here?

quotemsg Yeah, the two 4GB sticks are the same, Ill try moving one to the. The sticks were on grey slots (A2, B2) which were recommended in the manual. Or try to put the two 4gb ram stick in 2nd and 4th slot. Have not tried to use different slot patterns yet (just came to my mind). I'd probably buy a new one and a new case where I could change the the rest of my hardware. Is my main concern a bad RAM slot on the MoBo? Because I'd not look forward to RMA it. I switched the sticks, same thing happened (although I let the Memtest go on 'only' for 10 hours). Memtest passed cleanly multiple times for 17 hours. I removed the second RAM stick (both 8Gb HyperX 2666 w/ XMP) which seemed to fix it! Played, watched videos, torture tested and did everything I could think of and no crashes anymore. I cleared CMOS, tried to play (safely) with RAM timing profiles, no OCs. Prima95, FurMark and few other hardware benchmarks/torture tests crashed a few times, sometimes not.Īt this point I suspected PSU or RAM, maybe MoBo or CPU. I tried to run a memory test (Memtest86, Memtest86+, mdsched) but they all got stuck at some point (again random, usually after few passes without errors). Sometimes DirectX, sometimes other system files. Few times I got a crash into OS with dll-problems. Sometimes the PC was unable to boot, MoBo giving (seemingly) random error codes. Sometimes the PC rebooted itself when it crashed. Usually a hard reboot with 5sec power button was needed. The freezes happened in random intervals, sometimes 2-3 hours, sometimes 2-3 minutes into gaming. It all started after OS re-install, yet I did it again and the problem remained. I lately started to get random (so it seems) crashes especially when gaming. 2x8Gb DDR4 Kingston HyperX Fury GTX 1080

i7-6700k (no overclock apart from which is caused by RAM timing w/ XMP) Hope someone will have time to waste enough to read this fully?
