urbanriot I started my x99 journey with a gigabyte X99-sli; for equal parts because it had a more sensible lane allocation even with 28-lane CPUs (which mattered at time of purchase) and I still had high hopes of doing SLI or crossfire on the system.
However, that board did finally die, which from the symptoms suggests a vrm on it grenaded itself for how suddenly it failed.
Board I’m running now, is a sabertooth x99 I picked up secondhand. With the 6950x, lane allocation is fine. It’s m.2 slot is also faster as a plus. Though I do agree that Asus boards can get quirky.
