Hello,
I was looking to upgrade my Asus Z97 Sabertooth MKI with a 4970K from 2x8GB DDR3 to 4x8GB DDR3 (32GB). I have two sets of Crucial Ballistics Tactical RAM. A single set worked fine for over a year - never a crash or any instabilities. I can get it to post with 3x sticks, but as soon as I add the 4th stick it goes into a continuous reboot loop (never POSTs / MemOK light lit red - pressing it doesn't help). I'm 99% sure I initially had my old 4x4GB G-Skill in this same MoBo and it worked with all 4 slots.
I loosened timings to 9-9-9-24/2T @ 1333 and juiced it up to 1.65v or a hair above and still no POST (XMP = 8-8-8-24/2T @ 1600 / 1.5v). Bclk is stock @ 100. I got it to post ONCE by placing the two older sticks in the same channel and the two newer sticks in the same channel - but only POST'd once. All sticks appear to be good as it will POST with any combo of sticks as long as I don't add the 4th stick.
Any pointers here? I know the RAM is not on the QVL - but I'm betting I can get it to work with a little help in the right direction. This system has been so stable with a mild OC that I haven't dug deep into OC'ing and RAM tweaking on the Z97! My X79 Sabertooth system didn't seem to be so finicky with 4 sticks (but uses a 4-Channel DDR3 controller, and is only running 4x2GB sticks!).
Thanks in advance for your help
