Asus TUF Sabertooth X99 Motherboard Review

While XMP dictates the memory operating frequency, voltage, and primary timings, the secondary and tertiary timings are set at the motherboard vendor’s discretion. That can lead to performance differences in memory-intensive workloads.

We used G.Skill’s Ripjaws4 modules set to their 3GHz XMP frequency to test memory bandwidth and latency numbers.

Asus' motherboard shows strong bandwidth levels with the memory clocked at 3GHz, although the latency is higher than on ASRock's solution. This implies that looser tertiary timings are being set by the motherboard.
