So I've been pretty unlucky with ram. In my first build I had to set a stick back, on my next I also had to send a stick back, the replacement was fault and needed sending back, then originally I couldn't find memtest errors on that set but recently tried again and sent them back and got another replacement. I use 2 sets of 2x4GB 1600MHz corsair vengeance, and since getting this last replacement both sets will boot up if I use them on their own, but together it just continues to reboot my PC (mobo shows 03 on the debug led which isn't in my manual, I did wonder if it'd be D3 but then I'd assume it'd be clearer that it was a D).
Using the power of google, I tried upping the voltage to 1.565v which didn't work (now set back down to auto 1.5v), I then tried pressing my cmos button where my PC still reset until I took 1 set out which then let me clear my cmos but after wouldn't let me use them together. I have the latest full release bios, though there are newer ones from 2013 that have increased memory compatibility but are beta drivers. I'm not sure it's wise to use beta bios versions, though if I did I'm not sure how I'd do it since @bios shows the latest stable version and on the mobo site when I extract the exe for the bios it won't run (maybe due to windows 10).
All in all, I underestimated issues in matching RAM sets even though originally they played nice together apart from occasionally BSODs... Also I did test the new replacement with 12 passes of memtest86+ which passed, though my last set seemed to pass too. Using the new set so far to check how it holds up. Anyway, any ideas?
