So i just did a pretty big system upgrade. Went from a 4 year old motherboard and cpu to the Asus Z170-a and an i5-6600k.
Yesterday, after I had finished the last of the installations, I went to boot things up and got a solid dram led. This was a problem for about an hour as i tried several combinations of the two sticks of ddr4. then something changed (really not sure what) and i was able to post! at that time i only had one stick in the B2 (far right) slot. so things posted, i was happy, i shut things down and threw the other stick in the A2 slot (as suggested by the motherboard manual for single instance dual channel) and for some reason, now the CPU led was lit and again back to no post! after another 45 mins of moving ram around i found that as long as the sticks were on separate channels, i'd post. The problem is that their preformance is sevearly hindered now.
At this point im not sure what to do! I've checked some other places (reddit, toms hardware) and really got no help :/
some notes:
system is watercooled
running 16 gigs of kingston hyperX 2133 ddr4 bought as a kit of 2x8
powersupply is pretty new so im sure its not that.
cpu has been overclocked to 4.6 ghz but that was after this problem so im pretty sure its not related
xmp switch is off
tpu switch is off
system boots when memory is in [0,0,1,1] configuration.
There is no fan connected to the main CPU headder (however in the bios i dissabled monitoring of that as it gave me errors).
if you can think of any suggestions please let me know! thanks for the help!
